This legit answered so many questions I've had for years about JZ flow and turbo sizing. Appreciate you guys for getting into the nitty gritty here!!
Will the results be somewhat the same for RB26’s?
@@hellghost1410 completely different motor, timing control is completely different, cam setup, etc…. So no.
@@hellghost1410have A watch of motive video they had a g35 1050 video for the RB
@@leighmanton7298 thanks mate yeah I already had a look and went for almost a 1:1 of their build
@@hellghost1410 nice one 👍🏼 what size ar did you get for the g35? Is it on boost before 5k?
The 0.83 Ar housing should have been tested on G35. That is the sweet spot
That’s what my g35-900 turbo has a 0.83 Ar housing 😎
Amazing job. Love the content. Nice to have creators that speak to those that enjoy more of the nuances of performance and engineering. You did a good job making it more in depth without being overwhelming. The community needs more of this.
I’m seriously amazed how nicely you guys went through all of the data. Thank you for making it so easy to understand and for going to all that trouble just to help educate your audience. What an amazing episode!
I love that sound of the turbo spooling up and that deep whistle, combined with that awesome straight six sound. 10/10!
So cool seeing you guys work with Franz! Absolute top notch tuner and he makes some really amazing wiring harnesses. I met him back in the day when he worked with the DSG(Dent Sport Garage) guys and it's so great watching him get this kind of recognition.
Great vid!
This must be one of the most informative videos on the channel. Thanks for doing the research, guys. I'm sure it will save lots of people the hassle of guessing what setup will work best for their needs, with there being as many opinions as people out there. Your findings also seem to confirm the big mystery of the small compressor housing not working as expected on my S13's GT2871R.
Really enjoyed both halves of the video!! You guys are always enjoyable to watch and informative 😎
This was a truly cool test you guys did, did not expect the spool characteristics to change and improve so much by upsizing exhaust housings. High Quality content from SA as usual. DP you're looking svelte bro, keep up the good work.
Appreciate you guys doing this kind of back to back testing
Great back to back testing, I love this kind of content. Keep up the great work guy’s
30 minutes of pure gold.
Guys, you have here, in your channel everything we need to learn, listen and share. The data followed by feedback is the most precious we human beings can have, numbers without knowledge are useless and this transcends in all professions, hobbies and little things in life even!.
I'm looking forward upgrade my S3 8P as well and i want to maintain as much as possible the throttle response and this video is a HUGE guide to what should i look into it.
Been waiting for this video for over a year! Awesome job guys!
For a street car, I'd be setting that G30 on the 1.01 housing - and then mapping in boost by gear, letting it rip in 4/5/6 and reigning it in for 1/2/3.
Would make an awesome street car.
true
Yeah, but Supras long ratio's you'll find that full boost by 3rd is fine. I run 15psi in 1st (600+whp), 19psi(700whp) in 2nd and 26psi(850whp) in 3rd onwards. Sometimes i knock 3rd down to 22-23psi depending on traction and tire condition. But you get about 110mph out of 3rd gear, so there's no need in limiting boost above 70mph. I only change into 3rd around 60-65mph.
@@Skirk84 on my old TT6, I needed to boost holding back in 3rd as well, on a 275/40 18 tyre. The Syvecs TC was cutting in, so I brought the boost down till the TC wasn’t kicking in too much in the logs
Hated the noise of it missing…
I make more power than this in my 2j car with my gtx3582r and used to use boost by gear with my 235's as it was needed but with 275/60/15 MT ET Streets totally not necessary. With a good compound it should hook with full boost due to the powerband.
G30-101 is the best fun street car...
But sadly they didnt try G35-83 which i suspect will be the best compromise for higher rpm flow and keeping better spool (they gone full circle getting slow spool like g30-63 when using g35 with 101 housing) 😓
G35 + 83 would have been interesting to see.
And when it comes to response, i think Japanese builds are where it's at. Japanese builds rarely go north of 700 hp because they don't use big turbos, and they also focus a lot on suspension tuning.
They rarely go over 450. Buddy
very cool episode boys! always love these detailed comparisons esp with tuners giving us the WHY. the supra rips!
I just wanna say, i think speed academy has some of the most tasteful builds/car collections on youtube. And all the info you get from these build videos is unmatched. I love when y’all get into the nitty gritty on these builds. I’ve been watching since the Targa Newfoundland build, it’s amazing to see how far y’all have come!!! Here’s to many more builds!!!🍻
Amazing Content, really enjoyed the way you guys put this together and always anchoring back to the goals for the car. Thanks so much
Man that car is just so beautiful. So cool that you guys got to Dyno all those different turbo setups.
Can’t wait to see this race, these 2 will be a great matchup with the Supra hitting boost early in lower gear, that gtr is going to kill in the corners though. Looking forward to it and thanks for keeping us entertained Pete and Dave!
I really enjoy this analytical type of video. Keep it up guys, love your channel!
Thank you for the deep dive into the curves! Love hearing about the analysis where you look at the overall power band, rather than just the peak numbers. The earlier spool of the G30 and the increased power/torque at lower RPMs was pretty interesting to see.
This was a great deep dive! Just as interesting, if not more, than a build series. I hope to see the same conversation about the GT-R prior to track time. Thank you for sharing your hard work!
I just got to the point when you explained what you plan to test back to back on the dyno. Epic guys, thanks for this.
I still appreciate this video so much for the 2jz community. Great job guys.
Finally someone making a proper video of testing all the housing garrett turbos are so great loved this vid dont think people are even realising this is minimal power car has a cat and e85 would be a massive jump
Great content guys… good to see these back to back, data laden.
Good choice going with the G30 1.01ar. Perfect street/track setup.
What a great video guys, fantastic stuff. For me, the most interesting things were actually on the second part of the video. In my humble opinion, I'd pick the G30 turbo with the 83 housing for better response. Looking at the graphic, yeah, both housings are spooling alright after 4500 at peak boost, but it's not only the shifting point, but the posibility to hold a gear lower in the revs and have a better pick up in the middle range, around 3500-4000 rpm, with the advantage of losing less time shifting, specially in the second to third gear shifts. But I get what Francis says about the 101 housing, it's easier to modulate the throttle if the response isn't that snappy. I don't know... I'm an NA guy, don''t mind me, lol. Cool stuff guys, love it as always.
I’ve been eyeing the G-series turbos for my next iteration build on my 2JZGTE swapped Mk3 Supra: and this video just demonstrated exactly what I’ve been wondering about which size turbocharger to choose!
Beautifully done guys - thank so much for this content!
I somehow find you on every video I watch 😅 hope all is well buddy!
@@Godeepgts11 Where there’s a Supra, there I am. 😂 All is good bro; I hope the same with you. ✌️😎
Any supra content is good content haha
It was a great video with all that data and your thought process with the build.
Can't wait to see this tear up the track. Keep smashing it fellas.
Great video guys! Love this technical stuff, super interesting and helpful
Amazing to see the effect of using proper fuel in a performance car!
Amazing video. I wish someone would do this kind of in-depth back to back on a 1J, but this is still so informative and well presented. Loved the techy 2nd half of the vid.
True, the 2j gets all the love lol.
Finally a turbo sized for normal power and not 1000+ HP! This was an awesome comparison of turbines and housings. I learned a lot from this, very very cool!
I love it! Tons of great data and information, especially since I'm currently struggling to pick a modern turbo upgrade for my car right now too :)
Lots of cool info. Wish we coulda seen the .83 on the g35, but the g30 1.01 was cool too. Good choice fellas thanks for the video.
One of the best video I've seen on RUclips. Turbo sizes, exhaust housings, pump vs 105, air box, filters, all the graph, etc.
Only thing missing is seeing the plots for the boost pressures and air/fuel ratios 😉
Having in the tuner giving some insights is really awesome for understanding. Keep it up guys. The Supra will dominate on the track 😈
I would have kept the G35-900....future turbo on my 7MGTE 😎 or a comparable Boost Lab one. 🤔 That's the size I'm aiming for after my old ball bearing 67mm.
Unbelievable now how a 62mm turbo can outclass an old 67mm.
Omfg I'm so exited. Your content is really amazing man. Keep it all up. Love the 30 min as well
God damn! This is going to be a great face off between the R34 and the Supra man cannot wait! Awesome videos like always Dave and Pete!
Great video! Thank you for this 🙏
Pete and Dave I’m so excited to hop onto your channel every time you guys upload. I haven’t got much into hands on modifying, or track driving but your channel has got me so much more excited about it just seeing you; showing off your community, talking about the nitty gritty, and the love y’all have for what you do is just so infectious to me. I can’t wait to see the R34 and the Supra face off, no matter who wins you two now have some absolute, minty unobtanium in your fleet that I hope put big smiles on your faces every time you drive. Thank you for going through all the effort to put this out there
The Super turnout a beauty. You must be proud of the hard work to get here.
Great content! Considering me and my buddy talking about turbos for the 2j this is perfect!
Great video and yeah love the nerdy stuff keep it coming!
Excited to see this, guys.
I have the disadvantage of not knowing anything about turbo’s and not having english as my native language but man, I’ve enioyed this video sooooo much. Especially the dyno runs, I had my soundsystem on full volume to hear that beautiful music that engine makes❤️
Only an info-nerd watches until the very end. That's me, I'm an info-nerd.🤓 Keep it up guys!!! One of the best channels on RUclips!!!!!!! Great balance info on the tech, how to, and all other aspects of car content!!😎😎😎
Very educational video! More of these please should you have the opportunity.
Personally I would have went with the G30 and 0.83 housing.
Was about to go to sleep but hell yeah new vid! So keen for this one
VP MS109 (109 octane) is unleaded and oxygenated if you’re ever needing more then 105 octane. It’s what we run in our car and has been amazing. Great video, love the comparison work you guys did, that’s a lot of work for some amazing information and data!
E85 is about 109 octane and probably half the price of race gas, so there’s that. Plus it has far superior cooling properties. Too bad we can’t get it at the pump in Ontario.
Actually if you use the same octane numbers, the Sunoco is 110 RON, and the MS109 is 109. Sunoco use the AKI numbers, (so 105) rather than the Motor or Ron numbers. The Sunoco EVO10 actually has a slightly higher oxygen content than the MS109, plus doesnt contain MTBE, so wont eat your engine bits.
Great video with all the comparisons! One suggestion: it would have been helpful to bring up a table with key attributes you guys were looking for out of the setup (IE spool, peak power, boost pressure, race gas performance, pump gas performance, etc) in the first column, and then have each setup filled in with the characteristics as you went. Maybe it was just me, but I had a hard time keeping track with all the options.
What a great video to show all these options though!
I really wanted to see dyno hits from 5,000 or 6,000 rpm to actually compare response. I feel like rolls from down low can't really tell the full story. Needless to say I still really like that you guys talked it all the way through. Still stoked on a 2J response build instead of yet another dyno queen.
This was a great video, thanks!
This has just answered all my questions about turbo sizing on my stock 2j. The point on having all the power top end that is not usable on the street is legit.
The biggest advantage of the big turbos is taking out stress on the engine and drive line. Lowering IAT’s and EGT’s is massive for engine longevity and able to lap consistently without having to stop all the time to cool down.
Really really informative... thank you so much.
So much work and just as much data. Thank you very much, this helps a lot of guys out there.
IMO you should have gone with the 0.8 housing on the G30 for a street car. You had ~70ft lbs more tq right before 4k rpm with the smaller housing, that's nearly 20% more tq, but you only gain like 20-30hp up top with the 1.01 housing (which is only ~5% difference).
Car looks and sounds amazing btw =)
This vid solidified how important ar is and made it clear for a 400 to 500whp 3.0L the gt30 .83 or .86 ar is the way to go.
Dave, that shirt at the end is killer haha, can't wait to see some street pull👌
Wow 🤩, it’s 2:51am in Guam and this video was uploaded just 4 hours ago.
Can’t wait to watch this whole video later 😂
Great video guys!👏
Proves what I have been saying for years, a well built engine running a modern turbo always responds better on the bigger turbo, the IAT’s drop, less boost needed and the bigger turbos give better fuel economy.
Another advantage, the big turbos also give a form of boost by gear, in 1st and second engine rpm acceleration means they push slightly less boost which is good for clutches and grip, 3rd gear and up the turbo spool match’s or exceeds rpm gain so you get max power… really enhances the big engine warp speed feel in the car.
Try the two larger turbo sizes on the street and see what you like. Another option is have a switchable map so as the turbos are easily exchanged you could run a smaller turbo on the street and a big boy for the track… But I cannot see you go small now.
Thats cool, the second paragraph explains a lot of Honda turbo builds in particular. 3rd and 4th always pull harder even without a boost by gear computer setup
I agree as long as it's not laggy. But i run a 67mm turbo on mine vs the g35's 62mm and mine is more responsive than this setup, i run boost by gear and am not stressing turbo, engine etc until i get into three higher gears. On e85 im making around 480kw atw on 15psi (low boost). Easy power. And 410kw on pump. Both great for street and super responsive, full boost at 3000rpm
Id run a borgwarner s366 sxe
@@Skirk84 what turbo are u running and what A/R? Also what exhaust manifold (twin scroll or Single) and cams?
Thank you guys for the great content and cars!! I like your channel and the builds you've been doing this last year big time. Thank you. I do think that one of the things I'm disappointed in is that there seems to be no interaction between you guys (even if whomever is reading the comments is from a team of people we don't know LOL). I never see any response from the channel in the comments section. So questions seem pointless to ask and that makes any community feel here seem non existent. Or at best only one sided. I'd like to ask about the choice to run a smaller intercooler and the idea of better low down torque and power for street fun and enjoyment. But it's pointless as you don''t interact. That's what I mean. But thank you for the great stuff!!
Youre not looking hard enough, we answer questions all the time. We simply cant answer them all though
Not into supras or JZs but this one looks nice. Enjoyed the video but felt few things could have been improved / more thorough.
I think the G35 with .83 housing would really have been a good test and may have been a great compromise between the G30 & 1.01 and the G35 & 1.01.
MAP trace at the very least would have been nice. Either as part of the ECU logs or connected to the dyno.
ECU logs with turbo speed sensor would be nice to see.
Obviously wasnt planned and but for something like this seeing pressure ratio and EGTs would be extremely valuable.
Also don't think that "larger" filter was the solution to the restriction.
Airbox closed 486whp
Airbox open 506 whp (difference peak 20hp / 4%)
Small filter & airbox closed 617whp
"Big" filter 632whp (difference peak 15hp / 2.5%)
To simulate road conditions at least marginally more could have tried moving the blue fan closer to see if there was any difference there.
The wavy dyno chart up top is slightly concerning as that's already got a smoothing factor of 5.
Thanks for the videos guys ✌🏻
Great video guys! It helps a lot to choose a turbo for my project. Thanks a lot) BTW why you didn't choose twinscroll setup to get even earlier spool?
Im happy I sat all the way through that to hear the vinnegar strokes jokes. You got a full blown lol out of me.
That is the best turbo blow off sound I have ever heard on a Supra.
If low and responses what you’re after I’m surprised you’re not using a VVTI head, That paired with the G 35 turbo a truly give you the best of both worlds
Gem of a video... thank you.
Holly cow! That supra made so much power, it blew off the air filter!lol. Love there approach to making usable power and not focusing on peak numbers.
Love this build!
Thanks for the effort
EARLY SPEED ACADEMY UPLOADS. WHAT YEAR IS IT!?
Yeah 😯 really liked this one
2022
Damn. Damndamn. That thing is gorgeous. AND built RIGHT! Tune for fun and longevity, not numbers
Great Comparison video guys! It would be nice to do a comparison with a nice tubular turbo manifold versus that log manifold. In my experience those log manifolds choke up the engine just like that small .61 turbine housing did.
This 2J sounds Sofa King awesome! Great job DP and get ready to spank that GTR
Hope you guys do this type of testing on the S15 too. Would be great to know how the SR20 reacts to different rear housing sizes.
Perfect build 👌
You guys are awesome 🔥
Love gifts presented in my YT notifications. Now time to settle in and enjoy.
Fantastic and informative video on the differences and nuances of small deliberate upgrades and their results. Using data and knowledge from your tuner is the best way to modify and build cars. MKIV Supra owner here and mine is built. I am interested to know how cool your IATs (intake air temps) and engine stays during street, stop and go, and track driving. Mine is also built to be a street/road course car.
Amaziiiiing ep guys!!!
Love the show boys great content. I knew the twin turbo Gtr with less power and 4/11 gears would beat the single turbo Supra, the smaller twins on the Gtr make a load more torque so much earlier in the rev range and I would guess a whole lot more torque revs for revs than the supra,that's why nissan went down the twin route because they wanted response!. I also get confused when north American based youtubers say race track, because you mean drag strip,in the U.K. when we say race track we mean circuit. Thankyou boy's keep it up,would love to see more in depth engine builds being an engineer. ❤
Always love your MKIV content! Few notes from experience: 1) The G30-770 is way too small of a compressor at 58mm for a 3.0L 2JZ. Even the 35 series at 62mm is undersized. Boost threshold will be good, but you have to seriously de-tune in the lower rpms due to the quick onset of torque capable of bending stock rods. 58s and 62s will bend stock rods quick even at meager peak hp. You're better off using a larger compressor because you're having to tune out any response capability of these tiny turbos and your dyno graphs reflect this. A 64mm compressor with a .84 or 1.01 AR seems to be the Goldilocks for stock rods and the closest Garrett option is their FP GT3786R-HTA. 2) As for cams, you mention "GSC 272", but they don't make those. :) Their S1s are 269 and their S2s are 274. I forget which you have? Hopefully S1s as S2s are for 71mm+ per even GSC. S2 or even 272s (HKS or BC) only show gains above 8000rpm with noticeable losses below that across the curve with 71mm+. On a 58-62mm it's all loss vs S1 or 264s. Cheers!
What you think of the pte 6262 .68ar? All stock internals 2jz gte.
@@damnitdang pte 6262 is basically a G35 series Garrett. Too much low rpm torque unless seriously detuned for stock rods. Do searches on supraforums for this overwhelming concensus. 6466 minimum. A larger turbo might seem worse for keeping stock internals happy, but it's low rpm torque, not high rpm hp that will bend the rods. For better low end response do a 4" dp, stock intake manifold, mild cams or even stock, and E85 if possible. It's all a balancing act with stock rods. Or build the lower with 10:1 compression and send it.
@@96SupraTT very informative thanks!, only think is my motor is completely stock. And plan on keeping it that way ,unopen.. until I need to fix it. I bought it from my buddy like this . But it jist have cheap tubular manifold, pte 6262dbb .68ar, sard800cc, old aem v1, fpr. 3inch DP. Will be doing a 4-4.5" DP fender exit. It's a s30 chassy.
I'm redoing the ecu. Bought a emu black, flying leads. And soon a pmu16. Goal is 500-600 91-e85. I was thinking of saving up for a BW8474 black. They say it's a good turbo even for stock 2jz. I'll probably stick to a .83ar if I go that route. My current setup is responsive. Which is good.
I personally have Manley Htuff rods , GTE pistons , GSC S1 Cams and springs to retainers. I was thinking G30-900 1.01AR on e85 or the 1.21AR. a responsive 600whp
Isnt the turbine more problematic beacuse its so small if u compare good old hx35 has 70/60 turbine g30 has 60/55
This video is what I expect from SA. Teaching us what the actual demonstrable and measurable differences parts make on any given project so we can all decide which mods are worth it. Academies Teach.
I know it's not apples to apples, but I love these videos because I'm trying to choose a turbo for the M54b30 in my e46
Same here. I'm probably never going to own an R34 GT-R, but I get a kick out of finding the best, responsive turbo for an RB26.
Thanks!
Great video!
we need more back to back turbo testing.... this is the info ive been looking for. 500hp suprised you did not do 3" cat back.
To me this is thebest looking supra thanks to the colour and wheel combo.
After all the very interesting content I got answers to a lot of questions but gaind even more 😂.
When artec launched the manifold I instantly bought one together with an G30-770 .83. hunting the ultimate response. Difference is I'm using a Vvti and 264° by Titan... I was hoping for 500 at the wheels...as I see now, that's not going to happen without an intake or porting... but on the other hand 10psi below 3000 is nearly as good as stock😅
Amazing video guys but I cannot believe you tried a .63 housing on a G30 over trying a .83 on the G35. I feel you ended up wanting a power band between the G30 and G35 with the 1.01 that the G35 .83 would have delivered. Also I expected to see a G30-900 in this testing as the power delivery would suit a 3.0l better. Regardless, can't wait to see you on the track!
If anyone is interested in seeing a 600hp 2JZ-GTE JZA80 with a G30-900 on the track, look up Eddie Yilmaz on his Sandown track day.
I agree 100% on a 6266 which is a similar turbo the 0.81 open housing is the sweetspot
I feel the same as you. I really wanted to see the g35 with .83. I like to compared the dyno chart with the one of my VR6 turbo.
I do wonder if the G35 with the small housing would be the sweet spot between the two… Great video
This is such great data. Got a potential LS 4.8L project using a couple of turbos. I'm thinking either G30-660 1.01 / .83 thanks guys!
Response is still gonna be very good with the G35. If you really wanna drive it on the track a lot it's gonna live between 5 and 7k rpm anyway.
Boost comes in around 3800 rpm’s for me, t4 will probably have a better response the the vband set up I have. G35-900 1.01
The data was surprising to me. Me and friend did a similar test with our Supras 10 years ago. We tracked the benchmark of what rpm it makes 300 lbs of tq. The whole test was documented on supraforums. Stock engines, Proefi, no cams. 6spds.
Car #1 was a bw 88/75 (62mm) on full race manifold twin gate, e85. Hit 300tq at 3350 rpm
Car #2 was a SP manifold with Quick spool valve on a 67mm billet PTE e85. Hit 300tq at 3150 rpm.
For ref this car G35 62mm on 104 oct made 300tq at 3800rpm. kind of surprising, It was so laggy for a log manifold on 104.
A G35, vvti, QSV, and e85 would be a wild setup. Car number #2 was a monster felt like a V8 on the street.
i love all the data!
My kind of numbers and reasoning for keeping it under 700whp.😃👍🏾 Nice job!
Thanks guys this was reliable R&D from a moderate power level for a known performance level... Always something to think about when using a specific platform. 2jzPowa💯🏁🏁🏁🏁👍👌
i want to go back to the 90s just so i could tell the Supra guys that in the future if your supra doesn't make 4 digits on the dyno people will yell at you.
