Your channel is sooo underrated. I love all the experiments you do. Honestly I have been getting into turning my own car, subaru brz. It took me a good 4 year to feel comfortable enough to do it. I would love seeing you talk about the tuning process and challenges you work with when when running various test with different hardware.
This! Best content on youtube for petrolheads!
This is really great R&d content, very educational... Super underrated fosho
I agree
Agreed, this is heavily underrated, you deserve a lot more views than you get.
I suspect if you title your videos more something like NON-VVT VS VVT - Dyno tested. titles can be what makes or breaks a videos exposure iv found!
Would love to see the machining involved in making the 20v vvt solenoid fit. Cool concept and cool vid
You can see it between the alternator and the engine block.
I'm guessing he is using the solenoid on a remote block to send the pressure in a plate right behind the vvt pulley.
The tricky part is the machining considering how little space there is behind the pulley.
Pretty much as above ^ . the solenoid itself is a walk in the park. just remote mounted it. pulley not so much. getting the oil through the cam and into pulley is the tricky part
@@Garage4age Would you be willing to offer kits for sale for this retrofit? vvt is what i like the most about the 20v. The looks and modbility of the 16v i like better though
@@Garage4age hey! Just thort I'd check in on ya. Hope all is going well. Been missing ur videos. Watching from ohaupo in waikato.
@@javinhunt1199 Hey man, I'm still around. Just been working like a normal person unfortunately , so haven't had much time for this. plus the turd is getting pretty tired, so saving it for one last thing before comes out..
Hearing the ITB resonance change when the cam phased was very entertaining.
Thanks for the testing! Love your work.
This one just proves why manufacturers spent so much time/money developing VVT technology over the last 30 years.
Already want to get full vvti on there !
@@Garage4age next up.. maybe dual vvt... Just for exhaust, it zero out on retard side.. cant wait to see this.. yum yum...
Then plonk the dual vvt setup on turbo 🚀
@@Garage4age would you use beams cam gears or something like that?
indeed. today's VVT can be tuned for either performance or efficiency much more precise. i don't get why some people went back to fixed timing!
Mate, we’ll done! I could imagine you have spent a lot of time getting this sorted. Hats off to you sir!
As said a few dozen times, your channel and your content is a gold mine of information and is criminally underrated.
An excellent practical example of the benefits of VVT. 👏
Awesome! If Toyota just fitted vvt to the 16v they wouldn’t have needed to develop a whole new 20v head (twice)… great work man.
Haha yeah. they just needed to put the itb's, vvt & same size cams as 20v runs, on a stinky old bluetop and probably would have gone better
I think this is the best test you've done to date, never heard of this being done to a 16v. Please post a vid of how you did it and all the machine work. Next step would be is to control how much the vvt advances.
Not ready to give away how i done it just yet. plus still in testing stages, need to run it for awhile makes sure its reliable. I looking into full vvti, see if its is possible to adapt. The pulley on there is pretty limited what can do with it. is a sealed unit
@@Garage4age here in South Africa I remember some time back the guys that where doing rallying with the ae111 20v did do a mod to the vvt gear which allowed to control how much it advances, it involved drilling two holes in them and adding a threaded stud and nut which you then adjust, so it's definitely possible just don't have the exact details of how it's done.
@@shahengovindpershad8599 Yeah probably isn't that hard to do, just need one to dissect to have a look inside. The travel isnt too much of an issue on this setup. Just a fully variable setup would be better
@@Garage4age
I’d be happy to send you one to test on
@@mikemikeyee nice one! Message the man :)
Now do TVIS and VVT :P
Love the old school sound of the 16v 4As, but as a beams guy I always love the way the tone of the engine changes with increased revs. its instantly recognizable that this engine has VVTi as soon as the throttle opens at low revs.
This ain't no intelligent VVT is is binary lol. VVTd. d=dummy. What does the I even do?
VVT on the 16V? Really cool, hope you'll eventually post more info on it although I'm sure replicating it is beyond my skills :D
It's great to see those mid range gains with VVT. Epic to see it on a 16v. Really nice work!
For toyota enthusiast, we all know that 20V vvt pulley is hard to get & becoming pricey each year. Would love to see you posting other video using other alternative vvt pulley that is easier to get & cheaper. ❤
Love that you really let ideas sink or swim based on the dyno. Been loving your channel!
Wow! That's a huge difference. It would be very interesting to see dyno test stock flywheel vs light flywheel. Great channel!
another great video! love the detailed testing. your videos had blown away so much hearsay about engine tuning. love it!
Thought about this idea a long while ago couldn't believe my eyes when I saw you'd posted this! Great stuff man! Love to know the implementation details!
never knew you could add vvt! this seems like a top tier mod. and it looks like you now adjusted your rev limiter. so great
You have got to be the most informative channel there is! If you take any suggestions for videos, I'd be keen to see the difference between equal length vs log turbo manifolds, or maybe even twin scroll if you have access to it??
Probably not anytime in the near future, but is something i would like to try at some stage. never been a log fan myself haha
Can’t wait to see what’s coming next
Recently bought a 2nd car to modify for track use. Your videos are super helpful to see what works and what's rubbish. Thanks a lot mate!
You're doing the lord's work. I love your no-nonsense approach to videos, you get straight down to business and the meat. Great work!
Haha, awesome content once again. It's a shame most won't understand your content, but I do enjoy your handy work and sense of humour 🍻😄
awesome channel. ridiculous repeatability in your whole setup and awesome results from your experiments. always a great watch 👍🏼
you get that when you've done so many runs on same car. hit 1000 run milestone while making this video
Impressive gain. Congratulations 👍
Very Nice :) I am from Germany and i love this Chanel. This 4AGE is amazing 🔥 the Test, the Sounds. 😎
No doubt your most interesting and valuable experience of your channel
I've always wanted to see this! Thank you!
Best vvt video evver
Sounds like lots of fun to me.
Stunning car!
Luckily you are making videos about you knowledge. This is really beautiful
For years i thought about how to do this. Thanks man
Awesome boet, vvt on a 16v motor 🙌🏼🙌🏼🙌🏼🙌🏼 well done man
Seems some good gains from it
epic job, that made a huge difference
Love this channel. Interesting experiments with very informative results. Plus you get too hear Toyota's finest scream over and over again.
Impressive job, as usual.
👍
Wow that ripped on the top end, i cant wait to see whats next
Great video, gold, gold, gold, thank you
cannot wait to see you bring this evolution to the 4age community
I'm impressed how consistent your second runs are with the first. The VVT pulley made a good difference up top didn't it!
over 1000 runs on this car. So yeah have got it pretty dialed how to get consistent numbers out of it. big part of it is the oil temp.
Well that was a worthwhile upgrade! NICE!
I loved my 85 Corolla gts!!! That 4a-ge motor was unstoppable
Thank you so much! I need so much this video!
just the vvt off vs the vvt on area under the graph improvements were impressive to me!
VERY cool and look at all that meat you picked up for coming out of corners!!!! wahooo VVT FTW
Please do a video on how u modified your 16v to accommodate the vvt setup...
This thort had beeen in my head for a while, its great to see someone actually carry thiss out.. Great stuff hope to see a video soon of how u went about adding vvt to this 4age 16v
That was cool. Well done.
Game changing moment right here... 👌
What an amazing video!
Whole different animal for sure. There's a lot of tuning potential right there and still have to do the exhaust vvt for even better refinement.
Finally a new video
Great job! really!
Would love to see a twin vvt (exhaust + intake).
Awesome channel content.
Thanks. It would go better with some bigger cams! 😀
Crazy gains in lower rpms with Vvt On.
It will feel like different engine!
Great work
wow impressive how in a single video you set a debate i had with myself from the day i learned to tune engines, thanks for all the work and keep it up! PD: you should start to test real camshafts broooo
this is actually such a game changer for 16v users
Great work mate fantastic content, keep up the good work , pity you weren't into the 2.5 mazda 2009-2013 , one mighty solid engine forged internals are standard .
Outstanding!!!!
Wow 👍🏻 good job
Now, this was an awesome test! Next up, free valve! 😁
Yeayyyy.. long live vvt!
The master.
Great video
Thanks, you got a much nicer power band out of that.
I thought about retrofitting single or dual VCT to my engine but, it's a lot of work for my car. It would be easier to design more aggressive/variable hydraulic lifters, and that's not exactly easy. Variable length intake runners would probably be the best compromise.
Thank you
Nice work 👍🏻
I wanna see a 4-2-1 header
Mate I agree with all the others need to get this video out there also wouldn't mind seeing a twin injection down low first injectors and then up high second set of injectors
now this is interesting
That real nice
Love my vvti 2jz
Awesome 👍
I was just thinking about this
This channel is so FKN good. I suspect you would get more hits if the title was more skewed towards (for example) Dyno Testing Engine Mods rather than the focus on 4age. As some people will think the content is irrelevant unless they have a 4age.
That was killa!
Next step, a crank angle sensor and VVT on the exhaust cam!
Any chance of showing us what and how you've achieved adding VVT to the 16v head?
4:42 no huge lumping distributor there so probably he already has a CAS (unless he tuned it on TPS like the Japanese does)
Great vid, would love to see the effect dual VVT would have.
VVT + variable runner length ITB-trumpets would yield maximum power band utilization for naturally aspired, only remaining thing to get right would be optimizing compression to fit the variable range the best. Problem is, the difficulty of variable runner length, as anyone who has seen such on the 787B's engine, it goes back and forth to match each given point of the power band that needs a given runner length.. so that would require a linear actuator that was constantly matching the runner-length to the power-band's required length for optimal flow and speed
Another clever kiwi it seems 👍🏻
Love the straight forward testing you do and trialing all the little configurations many of us have pondered but never done. I haven't been following your channel long, but was curious why you aren't using the 20V head? I'm guessing the current 16V head flows better or what is the reasoning? Thanks again.
Haven't done a whole lot of development on the 20v head. 20v little better out of the box (blacktop at least) but has its imitations when comes to cam profiles due to the smaller bucket area.
Impressive. Specially with that relatively low 10.3:1 compression.
You could also estimate the theoretical difference VVL would make with VVT if you merged 2 VVT runs with different lift cams.
That being said this is probably the best example I've seen of why both technologies are great on street cars.
And there come the 2zz vvt+vvl
Did you use the 4age 20v original vvt intake cam gear?
Incredible video, congrats!!
Reminds me of the HKS V Cam they made for the RB26
VVT kicked in yo
Vvt kicked out yo
Great idea and great videos as always.! Now lets see if I got this right.. Stock 16V intake cam with an adopted 20V vvt pulley and stock exhaust cam?
hello, in the meantime I want to congratulate you because your videos are wonderful !! a doubt, however, came to me, so the cam on the intake side is more delayed, the more the shot is on the other regimes ??
Impressive, matching your previous peak tq that was at 5500 rpm now at 2750 and staying above previous peak for another 5000 rpm from there.
I love that you actually test meaningful changes and post the dynos. No BS.
As below, Id love to see the internals on your solenoid block/cam phaser.
Subscribed!
Chuck another phaser on the exhaust! Mod it to expand only the num of degrees you need.
It's awesome!
Was thinking of a way of doing it on a Honda but didn't really have time to go on it!
How did you make the vvt engage on your non vvt head?
I'm really curious about what you came up to make it work, it's really game changer especially with big ass cams ah ah
Good engine tuning since it havent lost any down low power.
👍👍
I'd love to see tvis, vvt and an exhaust cut out, all triggered at the most beneficial rpm in the range. I'm thinking you could really manipulate the sonic pulse that reverberates at the back face of the valves in your favor.
Love your content and I don't even have this engime! Do you happen to have oil preassure in the logs? It would be interesting to see how it is affected by the VVT activation/deactivation.
Pretty much zero change in oil pressure. It runs the same oil pump as the 20v engine the vvt setup come from. It runs about 75psi oil press
My car has VVT and I really like it, compared to the same engine without, it gained 7HP (on paper) and has a flat torque curve, max torque from just 2500rpm, the torque is what really makes the difference in daily driving, it pulls nicely from down low, smoothly all the way to the redline :)
It has 7 degrees (maybe more) of pwm control though+ variable length runners, it may be the runners that make up the power difference actually (long runners same as before facelift, but added short runners for above 3500rpm)
What car is that?
@@Jaredscott89 Mazda 6 1gen, before facelift 2.0 and after facelift 2.0 engine, only notable difference being VVT and variable length runners after facelift, long runners being same between them, but short runners added after facelift.
Had them both apart so am certain that's the only difference.
you def need to make a video to show how its fitted. Also would this work with stock cams? and hooked up to the stock ecu's tvis?
I've been wanting to do something similar with my B16B. Wanting to update it to direct fire ignition.
I sincerely applaud the effort, and only hope you'll keep going!
Unless someone comes out with a stronger block, this is exactly the kind of ingenuity that's needed to bring 4A-GE tuning into the 21st century!
Glad to see focus among 4A-GE enthusiasts around the world turn toward the ultimate reliable powerful engine instead of all the 11000rpm anime bullsh*t that has been so prevalent for decades 🤣
Can't rightly blame people though, the 4A-GE "death zone" above 8500rpm (engine block flex according to ex-TRD engineers, works teams & nzae86) isn't their fault, and it's weird that Toyota didn't catch it/let it go on throughout every iteration of the 4A-GE family, whereas with the FA20 they took steps within a few years, the backstabbers 😆
Thanks. version 2 vvt in early stages..
@@Garage4age there fixes for these problems tho.
Either way it's nice to see this engine getting so much love again
Would love to see the effect of rotating mass: lighter wheels, driveshaft, flywheel, harmonic balancer, crankshaft, etc
I really liked what you did there. Is that retro mod possible on any engine.
