The best thing to do with an HR is combined the two! VHR bottom end with stronger rods and pistons and HR heads with cams, add some boost and you have an animal of an engine!
Just for info, coming from someone with experience with the VQ platform and having swapped an HR into a DE platform I can confidently say that DE to HR is relatively easy, however a DE to a VHR is a lot more of a challenge. There's some great info you shared, and I appreciate your attention to this amazing engine platform.
I'm currently swapping a HR into a 2007 infiniti g35 coupe that had the DE motor in it and I am having some issues with ignition. The cars anti theft system life remains red and the car keeps running the starter and only runs after 20 or so times turning the key. Any advice would be most appreciated
@@vapor_knight8883 On the new ECU you've got to disable NATS. The person who built your harness would likely offer this service. If not, you'll need to have someone disable it in a tune or flash it or something
You really know your stuff man. Great video. Btw, in the real world, there's not been much of an improvement with the extra displacement of the G37. Sadly, the added weight/refinement offset the HP gains. If you wanted a lighter and more agile car, the G35 with the HR is probably better.
The HR and VHR share the same block. The "slightly greater displacement" of the latter is a function of the greater stroke imposed by a different crank/rods and can't be determined by simply looking at the outside of the engine.
I built a Ford FE 428 years back and used a Rhoads cam and lifter kit, it had pump up hydraulic lifters that kinda did the same thing. that said I have a VQ35DE now, and love it, and respect the HR's around :-)
Just bought a 2023 Nissan Frontier which has the new VQ38DD engine with a compression ratio of 11:1. Thing pulls hard and I'd like to see a comparison done with this engine.
It's very similar to the vq37 drove one of them frontiers and floored it and it sounds exactly like a stock g37 just that it doesn't go up all the way to 7400 rpm but yeah the engine sounds exactly the same
I own a 2004 350Z and a 2014 Q60S . Both have 6 speed manual transmissions. I can tell from experience that my old 350Z has a LOT more bottom end torque then my newer Infiniti. But, the Infiniti's 3.7l engine winds up a bit higher and has a bit more power at the top of the RPM curve where as my older 3.5l seems to develop it's top hp at much lower RPM. Basically, I can get a strong pull from the old 350Z at as little as 1800 rpm where as my newer Infiniti's 3.7l engine does not start to pull strong until at least 3000 rpm. As for acceleration, the 2014 Infiniti I have accelerates to 60 at the exact same time as my old 2004 Nissan 350Z. Of course, the Q60S outweighs the old Z by over 500 lbs. Gearing is the same. By this I mean the cars run the exact same road speed at the same RPM. Advertised HP for the two cars is 287 for the Z and 330 for the Q60S. Both engines run very smooth and neither uses oil. The one thing the 3.7L does not do that the 3.5L does is that start up rattle of the timing chain. The old 3.5L engine will give you this fraction of a second timing chain rattle at start up where as the 3.7L in the Infiniti is dead quiet at start up. So, Nissan must have done something to that chain tensioning system in the newer 3.7l engine.
@@corvettezr1ism Yea right. Well? it has a clutch, and a six speed shifter. It was made in 2014 and is an Infiniti Q60S. If you knew what you were talking about you would know that although rare, the Q60S made in Tochigi Japan can be ordered with a six speed manual. It was the last year for this setup. I believe I know the difference between an automatic and a manual transmission. If I had a way to send you a picture I would.
The only thing I don’t like about the vhr is the vvel system. They constantly come into the shop with problems and the vvel always gets screwed up some how. Other then that they are great engines. I’ve owned two hr’s and I can’t get enough of them.
I have 41K miles on the vhr in my Z and haven't had any problems whatsoever. The engine runs quietly and smoothly, using virtually no oil between oil changes.
This is true, the VVEL mechanism heat stresses the oil. The recommended Nissan engine oil that starts out as a 5W-30 gets sheared down to a 5W-20 after about 3K miles according to used oil analysis reports.
I love racing G37's in my G35xS.... (2008) I usually always win. That 7 speed transmission is supposed to be superior to my 5 speed. (I guess the Intake, Exhaust, & other small mods add up. My G35 is FAST! Just did the Waterpump & Gallery Gaskets also, so she's ready to run for a while!)
You are really a great information source for a guy who got tired of his GT500(still in garage), and bought a 09 G37 Journey to tinker with. I'm 2nd owner, and don't wanna change this car, or spend unnecessary upgrade money. So far Stillen catback, Z1 CAI, and going to Dynosty in Louisville, KY next month. (I live in KY). Old thread, I know...
More like rb26dett vs the vr38dett. Like previously stated 3.7 vhr would be better compared to the vr30tt. I'v heard that the vr30tt isn't as reliable but the vr30tt is more turner friendly and that's probably causing it's bad reliability
to be honest a lot of the reason why higher RPM's don't feel/sound right in the 370z is that the default tuning and VVEL system are really poorly done for high performance and sacrifice a lot of what you want at high RPM's for better efficiency/fuel economy at the low end. A decent tune will make a huge difference for driving it hard because of this.
I use regular gas in my 2007 G35. I've had no power or knocking issues. I've learned that if the compression ratio is more than 10.5:1, you should fill up with premium. After all the years I've owned my G35, I have always filled up with regular. 156,000 miles later my car runs like new, uses one third quart oil after 3000 miles, some of which seeps out of the original valve cover gaskets. My G35 is VERY fast, reliable and I love my blue 4 door sports sedan. Keith Schaedel.....................................5/12/2022........................
@@e46m54nissansr20937 Yea. Doing the same here. Mustangs are slow, 392's put up a good run but I still pull. Also beat an AWD Tesla model 3... ballparked him and he got an early launch
I don’t own my vhr 370z nismo anymore but damn that engine is solid and very linear. One complaint, I hated the exhaust noises. Changed the exhaust more than I change underwear jk obviously but you get it.
Not doubting your comment but it doesn't make sense. The Nissan bean counters could care less about the end user and would be more concerned about reducing costs. Changing the bolt pattern would cost more since it would require retooling the manufacturing process.
Which viscosity and brand of engine oil are you using on your VQ?! (Am running synthetic 5W30 on my 35HR because am scared of engine oil pressure issue or so due to using thicker engine oil such as 5W40 although i want to use thicker one..)
I've built a few of these, right now I've got an 07 HR with a vhr rotating assembly. In my opinion the rods look the same as far a design but with the vhr being shorter I'm thinking that's why they hold up to more boost. It's not much though, HRs usually break if exceeding 500 lbft at the wheels, vhr will hold about 50 lbft more, both in stock form. Torque is the amount of force exerted and generally is what needs to be limited on stock rods. Nice video👍🏼
Seem like the person to ask this question! I have and 08 HR. And I'm considering a 370 shell with engine and gearbox for a drift project as the 350 is Starting to get trashed. With both engines on hand, what route would you go? Keep in mind of the 350 is still road legal and registered. I was keen to supercharge the vq37 as it can handle the power that I need as I'm not going too high. Or do I just keep it Na, build the 35 and supercharged that? Any tips and advice would be much appreciated.
@@BB-pf2cs hey, my bad, kinda late in responding. Id keep the 350z as an HR for simplicity as far as the wiring harness and ecu but I'd swap out your 3.5 short block for the 3.7. Maybe get the heads cleaned up with a valve job and seals. I'd use Juke head bolts and oem HR gaskets, they've been holding up great for me at 10psi. You're basically using the 3.7 short block and everything else HR. The blocks have the exact same part number so it's truly a straightforward swap gaining a bit of stroke and about a 1/2 point higher in compression ratio
The VQ35 and VQ37 while tunable are getting on their age since there is no Fairlady 400Z coming yet. But now the next rage is getting the VR30DDTT and swap into the 370Z chassis. The VR30DDTT comes from the Infiniti Q50/Q60.
@@daneilfan3946 that i cant tell you. But my friend is doing the VR30DDTT swap and he using the 370Z gearbox with a custom flywheel and clutch. Motor mounts are needed to lower the engine
@@MrDaoby if you are lucky. You can get the engine from a co part car. My buddy got the engine and trans for 2/3k. And sold the trans and now only paid 1.5K just for engine and ECU.
VHR uses smaller spark plugs. Smaller plugs have less dielectric strength... meaning worse for spark in boosted applications... but they needed to do that for space the variable valve timing on exhaust and intake.
I have a 370z Upper and lower Mani on my VQ35HR. Sooo... Yes you can. You need the upper and the lower though. Also You can take a 3.7L short block and slap it under the HR heads and now you have total timing controll and something that easier to tune especially with aftermarket cams. The VVEL also heats up oil faster as its oil actuated. Most race teams use HR heads. Though on the street this probably isnt a huge deal.
I listen to a whole lot of everything! From Suicide Silence (when Mitch was still alive), Of Mice & Men, Parkway Drive, Attila, ODESZA, Adventure Club, Logic, G-Eazy, etc.
Seen over 600whp on the 35HR. Compression doesn't matter when it's cornfed. the VHR37 rods may be a tad tougher but when running E85 or better fuel who cares?
let's say I took my g37 to a junk yard/mechanic for a engine swap. Is it possible for them to throw in a vq35hr instead of the vq37vhr? I'm a little skeptical of what they did
Why do 37VHR hesitate in initial acceleration VS 35HR? I owned an I35 and an FX35 and now I own a QX50 with the 37VHR and it’s very noticeable. Thanks!
Yea I’ve noticed that when I bought the g37x l, I’ve driven an is250 for awhile until I bought the g, the 250 has great get up and good it really feels like it has more low end torque below 3k than the Vq37, I’ll have to use half throttle and at least 4K rpm to get up to the speed limit witch gets annoying because I just want to drive normally, these VQ definitely don’t have effortless power lol
Yea he mentions that in the video several times. They actually sacrificed low end power even with the longer stroke. He should have also mentioned the gallery gasket and the over heating issues due to vvel
@@nighthawk0077 galley gasket issue was solved after 2010 model year. My g37 had never once overheated. I even tracked it at the dragstrip and around a race course
@@corvettezr1ism do you have a VQ37 or the VQ35 hr or de? When I had the DE in my 03 350, it felt a lot quicker than my 370 just because of the kick it had at lower rpms. It felt more enjoyable to drive because I didn't have to put in as much effort
I got a quick question.is the vq35hr and the vq37vhr cam position sensors in the same place cause I can’t seem to find any in the back but two in the front(vq37vhr)
So should I sell my pristine 2008 g35 sedan AT w/ 65k miles currently and a brand new transmission put in at 45k miles.... OR get a 2014-2015 q50s to start modding for 400hp-500hp sport sedan? Would like to hear your experienced responses.
In regard to Rod differencs; contact JWT (JIM WOLF TECHNOLOGIES) ask for either Ben or Clark. They have tons of knowledge with Z engines and parts. Also Sebastian @ Specialty Z in Canoga Park CA is a high performance Z specialist engine builder.
I think Nissan changed the bolt pattern to charge more. Would it be possible to make a video about the Honda K20C2, sometime? Possibly compare it to older NA Honda K series engines? I know they did away with the typical exhaust design, going with one massive port, rather than using an exhaust header or manifold.
I love my vq37vhr, coming from the Acura TL Type-S the difference in speed is most definitely there, and railroad drive compared to front wheel drive is a whole lot more fun among having two more years to being on but other than that I kind of wish I got the manual but I do have a manual truck so kind of not missing having to shift gears all the time in the daily driver.
There is 0 debate, the VVL technology and the bigger motor from the VHR is far more advance in producing power with efficiency. I wouldn't even buy a HR motor for any price.
Well I can already tell your biased cause you have a 370z. But the differences between these engines are very minimal. The vq35hr is an amazing V6 and barely any different then the 37.
The video literally says they're the same motor on the bottom end. The bore is the exact same. The only difference is the increase in stroke. VVL is nice but it's not a make it or break it technology. To further prove a point, quarter-mile times and street race videos (even though you can't always go off of these) all show that the speed difference is usually focussed around driver mod or tuner experience. Considering you can get a 350Z HR for around $6000-$10,000, and the 370Z is usually $10,000-$20,000 (for one that's NOT brand new from the lot), I would say the choice is easy. Plus the 370Z interior is ugly XD
@@carlinleneker-frisch976 I know the vq40 is from a larger Nissan I have it in my Navara / Frontier what I want to know is a comparison video in the engines and what is different I know.the vq40 is like an inch taller in the block because of the stroke and that's where they get the extra Cubes from but what I want to know how different are the heads do the manifolds fit are the exhaust manifolds going to fit off vq35 or vq37 what I want to know is all the different comparisons if you're able to do that same question I asked before cheers Tony
Can you put the VQ37VHR crank in a VQ35HR and have a custom piston made with a higher pin height and end up with a VQ35HR stroker? Or alternatively, just swap out the VQ35HR short block for a VQ37VHR and achieve the same thing.
Saad Sirhandi I had a 04 g35 and it consumed oil but wasn’t anything out of control the thing I hated the most about mine was the location of that stupid ass dip stick.. like if you had an aftermarket intake you could hardly get it in.. but I upgraded to an 2014 Q60 IPL and absolutely love the VHR
Does anyone know the stock throttle body size for the VQ35HR. I've read conflicting info some say it's the same size as the VHR some say it's different. I plan on machining throttle body spacers at a friends shop
I have vq35de with vq40de crank and you need to made custom rods because vq40 crank have larger radius. my engine have compression ratio 8.0:1 and wiseco forget pistons. I have ~700-750hp with porshe twin turbos. Sorry for bad English
block is also machined different so that its more stable at higher RPMS and can handle more force and vibrations since it has oil passages around the cylinders instead of them being completely disconnected from the rest of the block (forgot the real terms for them lol) as well as other design features that improve performance. probably also has lighter weight and stronger crankshaft, pistons, and con rods so that it gets better throttle response and higher RPM. and some higher airflow design. IIRC the V angle is pretty different aswell. along with being twin turbocharged of course, which is the main performance gain along with the very slightly increased displacement. Nissan goes up and above with all of their GT-R drivetrain elements, like the dual clutching automanual tranny.
Maybe just swap the crank, rods, and pistons. That way you can benefit from the larger displacement and higher compression ratio without having to deal with the major differences in wiring, timing, and engine management.
Briar Stern I heard the 37VHR from 09-11 model years had that issue too so I’d rather stay with the hr and keep the reliability than run the risk of that vvt issue which is a hefty repair
Yes, they do! It's even worse, though. The 37 has no access port for the water pump, and you have to remove the entire timing chain cover to do it. I HATE this design. The 35 has given me more pain because of this than any other engine. Ford used the same design in their 3.7 duratec V6. They had many lawsuits over it as coolant would leak into the oil pan causing engine damage.
I know this video is old and there is probably an answer to my question somewhere but it doesnt hurt to ask this question as often as possible. I have an 06 350z enthusiast with the rev up de motor. If i plan to do only minor n/a upgraades and keep up with maintenance, do i really need to worry about my car blowing up? I want to push the performance of this car but I'm scared to because i see it all the time that my engine i garbage, cant hold power, blah blah blah. I have 3 inch y pipe open back to a greddy single, short ram intake and plenum spacer. Do i need to worry about my car detonating with minor upgrades if i push it to redline for extended periods of time? Its a drift build so redline is unavoidable.
I'm sure you've gotten some answers somewhere but everybody has different opinions so I'll offer a couple of mine from experience. 1. Run synthetic oil 1 or 2 grades thicker if you're beating on an engine. Oil as thin as water is for fuel efficiency and less drag on internal parts, NOT longevity. When race teams could qualify with a different engine than they raced with they'd sacrifice the qualifying engine with thin oil for a few more hp at the expense of the engine for a better start position. I run 15w40 in my turbo VQ37HR. 2. Don't beat on the engine until the engine oil is up to operating temperature. Get an oil temp gauge. 3. Especially on these cars, watch that the engine oil doesn't overheat during competition. Get an oil cooler and use an expansion style thermostatic valve to regulate flow to the cooler, some cooler kits come with one. Oil normally runs much hotter than coolant but keep it under 280°. 4. If you're constantly at redline, consider an oil pump with a billet steel gear set. At least you have a revup to begin with, they've got better pumps than the regular DEs. 5. Put an aluminum tank radiator in with new OEM fan motors (they're better than most aftermarket performance marketed fans). And when your done with a bracket or heat, or whatever it's called in drifting, let it idle for 5 min so that the fluid temps equalize before shutting it down. Take care, good luck
@@tksperformance8789 man I appreciate the info, thats actually very helpful! I've had the car a little longer and have learned a few things for sure. I do run 15w40 in it now but a big thing I learned about this particular car is that one of the previous owners swapped in the 03-05 de motor so I don't have the rev up. Also found out it has a few engine mods I didn't know about at the time. Has a plenum spacer and throttle body spacer. So this engine has oil pump issues? Is there anything I can do to boost that? I have 30lbs of oil pressure at idle which I've heard is good. The old method of whatever rpm you're at, your oil pressure should be double so at 3k I'm at 60psi. As far as I understand, thats an indication of a healthy motor. I'm going to look into the other parts you mentioned and start getting a part here and there. Haven't beat on the car yet because it still has a lot of issues with the chassis. Bunch of junk suspension parts and brakes are all warped from being beat on by the previous owner. Its been drifted before and I'm guessing the owner before the guy I bought it from blew up the rev up motor drifting it because he didn't have any of the parts you mentioned. Again, thanks for taking the time to offer me that info man, I really appreciate it!
@@tksperformance8789 looking into the pump, looks like its common to run the rev up oil pump with an aftermarket gear. Is this a good idea in your experience or should I go full bullet pump and gear. I seriously doubt I'll build this car over 400 hp unless I get a killer deal on a super charger kit. Even then I won't make more than 450hp. I know these engines tend to let go at that threshold unless you do internals which I really don't plan to do. So I'll probably keep it around 400hp max.
@@brandondeel3567 yeah I'm not sure what it is about the rev up pump housing but I've heard what you said about billet gears in that housing. I think you can run an HR pump too which in itself might be enough since the stock limit is 7500. HP isn't so much the factor with the pump, it's the extended high rpms that are hard on them. Crankshaft harmonics and I'm guessing the hydrostatic pressure of the oil is really high, that equals high load on the gears. Speaking of harmonics definitely don't run those cheap billet solid crank pulleys, you'd be better off with your stock pulley and ideally an ATI Damper would be a good idea, they're so damn expensive though. I don't have one on mine but i don't track it ever, just a single mid mount turbo for some fun on the highway. I think used Revups are getting scarce, most opt for the DE as a more readily available replacement so that's definitely common to do. Personally, if you like the car I'd find a wrecked HR with a good engine and swap everything if that motor ever let's go. That's what I'm most familiar with, I've got an 07. Actually I'm going to post a new video of a quick pull at 8psi. It's been down and i just got it back together and on the road. Check it out
(QUESTION). when driving an automatic g35, if i press the gas fast then let it go and it makes a downshift sound, and it makes me go way faster when thats done, does that ruin my engine over time ?
“The hr is clearly the superior engine” bro literally every vq record is held by a DE they’re about .4 seconds or so off the fastest 2j’s stop the nonsense
No, as far as i know, they updated ECU and exhaust setup. There are a lot of other things they changed tho, like the autorevup when changin gears, stiffer suspension, bigger brakes, facelift, interior changes etc. Overall, nismo doesn´t make that much more power, but it´s more oriented towards racing.
worst thing on these engines is the trans which have a cap on the dip stick tube on the trans which makes it impossible to diy change the fuel without a pump
This guy doesnt know wth he’s talking about… I have a 2007 V36 sedan 6MT that comes with the HR and I have G37 VHR Upper & Lower Manifold & Fuel Rail installed on my HR and it loves it.
I think the VHR rods look a little bigger and kinda a little stronger then the HR but don’t trust what I say I’m a beginner in cars and I wanna get a g37s coupe if I can in manual. I’m doing hella research on the car and seeing what fits and what don’t 🙂
VHR was mostly Renault, had Renault stamps all over... Supposedly it was changed around later (told to me by a previous mechanic colleague), but don't trust that info... The 370 never felt natural, especially the with the weird 'auto' gearbox 😑 The electronic rev match when downshifting in the manual version ticks me off as well, are they making the cars for grandads or for true drivers/enthusiasts?
Ehhhhhh you’re good on boost until about 500wtq in the VHR. Anything past that, a built bottom end is recommended. The VHR is better because of the torque curve and vvel, but if I were to build a race motor, it would be a VHR with HR heads.

The only thing I don’t like about the vhr is the vvel system. They constantly come into the shop with problems and the vvel always gets screwed up some how. Other then that they are great engines. I’ve owned two hr’s and I can’t get enough of them.
I have 41K miles on the vhr in my Z and haven't had any problems whatsoever. The engine runs quietly and smoothly, using virtually no oil between oil changes.
We rarely get problems with the vvel, sometimes the actuator goes out but it’s usually people not changing their oil
Other than the purpose of this video, today I learned that Bryce is a metalhead 🤘😈
IIRC the primary complaint about the VHR is that the VVEL mechanism dumps a fair bit of heat into the engine oil.
This is true, the VVEL mechanism heat stresses the oil. The recommended Nissan engine oil that starts out as a 5W-30 gets sheared down to a 5W-20 after about 3K miles according to used oil analysis reports.
This is why I use boron additives in my oil even then the oil I use already has some.
Jim Nesta i’ve always run 5w-40 seems to work good
Aftermarket oil coolers arent that expensive 😉

Now do VQ37VHR vs VR38DETT
Bruh VR38DETT is literally GTR VHR ain't doing shit lol😂
@@drippp4257 ikr not even fair n/a vs turbo v6
no the vrh vs the vr30tt
More like rb26dett vs the vr38dett. Like previously stated 3.7 vhr would be better compared to the vr30tt. I'v heard that the vr30tt isn't as reliable but the vr30tt is more turner friendly and that's probably causing it's bad reliability
I never modded it but I loved my 2015 370Z 🥰 I miss it every day, but imo it didn't seem like it was happy at higher rpm.
It was happy but I know what you mean gets real harsh up top. It was e engineered to live at those high rpms
@@stophatingmichael6767 double reinforcement compared to the DE gotta love that
to be honest a lot of the reason why higher RPM's don't feel/sound right in the 370z is that the default tuning and VVEL system are really poorly done for high performance and sacrifice a lot of what you want at high RPM's for better efficiency/fuel economy at the low end. A decent tune will make a huge difference for driving it hard because of this.
I use regular gas in my 2007 G35. I've had no power or knocking issues. I've learned that if the compression ratio is more than 10.5:1, you should fill up with premium. After all the years I've owned my G35, I have always filled up with regular. 156,000 miles later my car runs like new, uses one third quart oil after 3000 miles, some of which seeps out of the original
valve cover gaskets. My G35 is VERY fast, reliable and I love my blue 4 door sports sedan.

They moved the bolt holes to combat theft. Engines that are standardised become swapable and therefore more desirable by thieves.
Not doubting your comment but it doesn't make sense. The Nissan bean counters could care less about the end user and would be more concerned about reducing costs. Changing the bolt pattern would cost more since it would require retooling the manufacturing process.
@A C Depends on the manufacturer and their process. You can always find other places to cut cost.
I love my VQ35HR so quick and fun.
I bet! Probably way quicker than my turd DE 😅
My uncle has both hr n vhr fckin fun n super fast as foo👍
Which viscosity and brand of engine oil are you using on your VQ?! (Am running synthetic 5W30 on my 35HR because am scared of engine oil pressure issue or so due to using thicker engine oil such as 5W40 although i want to use thicker one..)
I've built a few of these, right now I've got an 07 HR with a vhr rotating assembly. In my opinion the rods look the same as far a design but with the vhr being shorter I'm thinking that's why they hold up to more boost. It's not much though, HRs usually break if exceeding 500 lbft at the wheels, vhr will hold about 50 lbft more, both in stock form. Torque is the amount of force exerted and generally is what needs to be limited on stock rods. Nice video👍🏼
Seem like the person to ask this question! I have and 08 HR. And I'm considering a 370 shell with engine and gearbox for a drift project as the 350 is Starting to get trashed.
With both engines on hand, what route would you go? Keep in mind of the 350 is still road legal and registered.
I was keen to supercharge the vq37 as it can handle the power that I need as I'm not going too high. Or do I just keep it Na, build the 35 and supercharged that?
Any tips and advice would be much appreciated.
@@BB-pf2cs hey, my bad, kinda late in responding.
Id keep the 350z as an HR for simplicity as far as the wiring harness and ecu but I'd swap out your 3.5 short block for the 3.7. Maybe get the heads cleaned up with a valve job and seals. I'd use Juke head bolts and oem HR gaskets, they've been holding up great for me at 10psi. You're basically using the 3.7 short block and everything else HR. The blocks have the exact same part number so it's truly a straightforward swap gaining a bit of stroke and about a 1/2 point higher in compression ratio
The VQ35 and VQ37 while tunable are getting on their age since there is no Fairlady 400Z coming yet.
But now the next rage is getting the VR30DDTT and swap into the 370Z chassis. The VR30DDTT comes from the Infiniti Q50/Q60.
can u swap it into a hr 350z since you can swap a 370z trans to a hr 350z?
@@daneilfan3946 that i cant tell you. But my friend is doing the VR30DDTT swap and he using the 370Z gearbox with a custom flywheel and clutch. Motor mounts are needed to lower the engine
I'd say bang for the buck though boosting a vq is still better and much easier compared to swapping a vr due to VR pricing for parts.

VHR uses smaller spark plugs. Smaller plugs have less dielectric strength... meaning worse for spark in boosted applications... but they needed to do that for space the variable valve timing on exhaust and intake.

In regard to Rod differencs; contact JWT (JIM WOLF TECHNOLOGIES) ask for either Ben or Clark. They have tons of knowledge with Z engines and parts. Also Sebastian @ Specialty Z in Canoga Park CA is a high performance Z specialist engine builder.
I think Nissan changed the bolt pattern to charge more.
Would it be possible to make a video about the Honda K20C2, sometime? Possibly compare it to older NA Honda K series engines? I know they did away with the typical exhaust design, going with one massive port, rather than using an exhaust header or manifold.

Facts I was gonna get a TL but wanted a rwd car glad I got a G
ummm... did you mention (or did I miss it?) the power/torque increases? any changetro max REVs or REVs at max Power/Tourque?
There is 0 debate, the VVL technology and the bigger motor from the VHR is far more advance in producing power with efficiency. I wouldn't even buy a HR motor for any price.
Well I can already tell your biased cause you have a 370z. But the differences between these engines are very minimal. The vq35hr is an amazing V6 and barely any different then the 37.
The video literally says they're the same motor on the bottom end. The bore is the exact same. The only difference is the increase in stroke. VVL is nice but it's not a make it or break it technology. To further prove a point, quarter-mile times and street race videos (even though you can't always go off of these) all show that the speed difference is usually focussed around driver mod or tuner experience. Considering you can get a 350Z HR for around $6000-$10,000, and the 370Z is usually $10,000-$20,000 (for one that's NOT brand new from the lot), I would say the choice is easy. Plus the 370Z interior is ugly XD

Different manifolds , bigger block , etc
block is also machined different so that its more stable at higher RPMS and can handle more force and vibrations since it has oil passages around the cylinders instead of them being completely disconnected from the rest of the block (forgot the real terms for them lol) as well as other design features that improve performance. probably also has lighter weight and stronger crankshaft, pistons, and con rods so that it gets better throttle response and higher RPM. and some higher airflow design. IIRC the V angle is pretty different aswell. along with being twin turbocharged of course, which is the main performance gain along with the very slightly increased displacement. Nissan goes up and above with all of their GT-R drivetrain elements, like the dual clutching automanual tranny.

Your better off just swapping the whole engine
Maybe just swap the crank, rods, and pistons. That way you can benefit from the larger displacement and higher compression ratio without having to deal with the major differences in wiring, timing, and engine management.
Galley gasket?
Briar Stern I heard the 37VHR from 09-11 model years had that issue too so I’d rather stay with the hr and keep the reliability than run the risk of that vvt issue which is a hefty repair
After 2011 or 2010 it was fixed by Nissan
VHR rods are 1mm thicker giving them about 20% more strength
Do they both have the same water pump???
Yes, they do! It's even worse, though. The 37 has no access port for the water pump, and you have to remove the entire timing chain cover to do it. I HATE this design. The 35 has given me more pain because of this than any other engine. Ford used the same design in their 3.7 duratec V6. They had many lawsuits over it as coolant would leak into the oil pan causing engine damage.
I know this video is old and there is probably an answer to my question somewhere but it doesnt hurt to ask this question as often as possible. I have an 06 350z enthusiast with the rev up de motor. If i plan to do only minor n/a upgraades and keep up with maintenance, do i really need to worry about my car blowing up? I want to push the performance of this car but I'm scared to because i see it all the time that my engine i garbage, cant hold power, blah blah blah. I have 3 inch y pipe open back to a greddy single, short ram intake and plenum spacer. Do i need to worry about my car detonating with minor upgrades if i push it to redline for extended periods of time? Its a drift build so redline is unavoidable.
I'm sure you've gotten some answers somewhere but everybody has different opinions so I'll offer a couple of mine from experience. 1. Run synthetic oil 1 or 2 grades thicker if you're beating on an engine. Oil as thin as water is for fuel efficiency and less drag on internal parts, NOT longevity. When race teams could qualify with a different engine than they raced with they'd sacrifice the qualifying engine with thin oil for a few more hp at the expense of the engine for a better start position. I run 15w40 in my turbo VQ37HR. 2. Don't beat on the engine until the engine oil is up to operating temperature. Get an oil temp gauge. 3. Especially on these cars, watch that the engine oil doesn't overheat during competition. Get an oil cooler and use an expansion style thermostatic valve to regulate flow to the cooler, some cooler kits come with one. Oil normally runs much hotter than coolant but keep it under 280°. 4. If you're constantly at redline, consider an oil pump with a billet steel gear set. At least you have a revup to begin with, they've got better pumps than the regular DEs. 5. Put an aluminum tank radiator in with new OEM fan motors (they're better than most aftermarket performance marketed fans). And when your done with a bracket or heat, or whatever it's called in drifting, let it idle for 5 min so that the fluid temps equalize before shutting it down. Take care, good luck
@@tksperformance8789 man I appreciate the info, thats actually very helpful! I've had the car a little longer and have learned a few things for sure. I do run 15w40 in it now but a big thing I learned about this particular car is that one of the previous owners swapped in the 03-05 de motor so I don't have the rev up. Also found out it has a few engine mods I didn't know about at the time. Has a plenum spacer and throttle body spacer. So this engine has oil pump issues? Is there anything I can do to boost that? I have 30lbs of oil pressure at idle which I've heard is good. The old method of whatever rpm you're at, your oil pressure should be double so at 3k I'm at 60psi. As far as I understand, thats an indication of a healthy motor. I'm going to look into the other parts you mentioned and start getting a part here and there. Haven't beat on the car yet because it still has a lot of issues with the chassis. Bunch of junk suspension parts and brakes are all warped from being beat on by the previous owner. Its been drifted before and I'm guessing the owner before the guy I bought it from blew up the rev up motor drifting it because he didn't have any of the parts you mentioned. Again, thanks for taking the time to offer me that info man, I really appreciate it!
@@tksperformance8789 looking into the pump, looks like its common to run the rev up oil pump with an aftermarket gear. Is this a good idea in your experience or should I go full bullet pump and gear. I seriously doubt I'll build this car over 400 hp unless I get a killer deal on a super charger kit. Even then I won't make more than 450hp. I know these engines tend to let go at that threshold unless you do internals which I really don't plan to do. So I'll probably keep it around 400hp max.
@@brandondeel3567 yeah I'm not sure what it is about the rev up pump housing but I've heard what you said about billet gears in that housing. I think you can run an HR pump too which in itself might be enough since the stock limit is 7500. HP isn't so much the factor with the pump, it's the extended high rpms that are hard on them. Crankshaft harmonics and I'm guessing the hydrostatic pressure of the oil is really high, that equals high load on the gears. Speaking of harmonics definitely don't run those cheap billet solid crank pulleys, you'd be better off with your stock pulley and ideally an ATI Damper would be a good idea, they're so damn expensive though. I don't have one on mine but i don't track it ever, just a single mid mount turbo for some fun on the highway.
I think used Revups are getting scarce, most opt for the DE as a more readily available replacement so that's definitely common to do. Personally, if you like the car I'd find a wrecked HR with a good engine and swap everything if that motor ever let's go. That's what I'm most familiar with, I've got an 07. Actually I'm going to post a new video of a quick pull at 8psi. It's been down and i just got it back together and on the road. Check it out

They probably made the rods slightly beefier to go with the increased compression ratio, which would increase strain on rods
VHR was mostly Renault, had Renault stamps all over... Supposedly it was changed around later (told to me by a previous mechanic colleague), but don't trust that info... The 370 never felt natural, especially the with the weird 'auto' gearbox 😑 The electronic rev match when downshifting in the manual version ticks me off as well, are they making the cars for grandads or for true drivers/enthusiasts?

Vq37vhr will be able to handle boost fairly well in a stock bottom end. I believe 600-650 whp is a reliable number to pump out

It can Handle the Horsepower, but once you get to 450tq thats borderline death. You can run 700hp, but your Torque needs to stay at 400 to be safe
Torque is what breaks parts.
Ehhhhhh you’re good on boost until about 500wtq in the VHR. Anything past that, a built bottom end is recommended.
The VHR is better because of the torque curve and vvel, but if I were to build a race motor, it would be a VHR with HR heads.
Thanks for watching! 🤟🏻
