4AGZE to 4AGTE. Whats the best part of your turbo conversion?
|

OK, I've got a question for all the people out in the world who have converted the 4AGZE to 4AGTE.
I'm interested to know who has done what to what and how it affected the motor.
For instance, Mr X had a bigport GZE and used a RWD GE maifold with a WRX turbo and mircotech and got, say 145rwkw. It comes on boost an X rpm and is running XXpsi. great round town, perfect for track etc etc
I would like anybody who has done this conversion to post up
what Turbo.
What mainfold.
What computer.
What you started with,(eg afm or map)
Rebuilt or not.
What rwkw your getting
why you chose to do it that way.
any other specs that might be interesting.
and the plus and minus sides of the conversion,
As there are so many ways to go and i have now idea how to go about it, Personally i'm not into drag, more track/drift/hill climb. But any info from anybody on the GTE will be great help

well, i'm somewhat similar to Mr X:
bigport GZE (stock internals - AFM model)
RWD bigport mani
late S14 ball bearing T28 with modified actuater
custom mid mount turbo mani
2/1/2 stainless piping/zorst
VR4 cooler
i haven't dynoed it but i'd expect around 130rw/kw - and thats with no tune, and all DIY work at home.
I took it out to the track last week to drift and boy was i happy/impressed with the difference, perfect power and response, and smooth.
plus and minus? well i can only give you pluses in the performance/efficiency side, but only downfalls i can thnk of are shorter clutch lives, driveline issues etc - but thats the price u pay 
do eeet

thanks ae86slaver, diff and box i know aren't the best in the world, but it does depend on your driving and how much you abuse it, i'm more interested in the motor side of thins for now, i'm hopeing to make similar power still charged, but as mentioned, still un tuned, keep me posted when you get it dyno'd i'd like to see what it's getting.

Turbo: T28 0.48A/R Exhaust housing (the baby T28)
Manifold: Custom made in steam pipe
What computer: MTX-8
Engine base: 4AGZE, AFM, big port
Rebuilt or not: Not
What rwkw your getting: Repeatedly makes around 165 - 170rwkw (on 17 - 18 psi) on various dynos around the place.
Any other specs that might be interesting: 2.5" exhaust, runs 12.8 seconds over the 1/4, full boost comes on nice and early ~3000rpm, my driveline is well and truly up to the task 
and the plus and minus sides of the conversion
Plus: nice and quick, easily driveable street car, good on fuel.
Minus: makes my other car feel dreadfully slow, has set a high benchmark for future vehicle mods and purchases.
Edit: Less time asking questions more time fitting turbos Justin

more time asking questions so i can fit the right turbo!
I'm still in a pickel, i have a big port head from my first engine, a small port on the new one, the new one's a map and the oil one's afm, i got plenty of options with that, and then there is inlet, exhaust, turbo, managment.
I figure i might go ask Jake, tell him what i got and what i want and work from there.

Build a big power small port to prove the critics wrong.
NB the small port ports are not that small

a turbo is like the question do you want a 20v or a ze? ze straight line 20v circuit
so if you want shit loads of power go for a big turbo, other wise if you want a track car then smaller turbo wrx s15-t28 even a ct 26 that has been high flowed. its a very hard question to answer with out telling us what you want the car for!

Justin just wants a turbo that will:
be perfect for the track and drifting
be perfect for drags
have no lag
be able to win dyno comps
be able to make 40psi
make that foooly sick VL turbo flutter so many people on this forum want 
only costs $200
and is readily available on the second hand market

AFM Bigport Twin Coil GZE
TD05H-16g turbo (ex-early model wrx)
3inch exhaust and twinpipe dump
Big intercooler 16psi
Not Rebuilt
AFM Gze management
Power: Undyno'd (will have graph next week!)
With a washer T peice for a bleeder, it hits full boost around 5-6k. So it's not a really good setup for drift. This is because of the big exhaust housing on the turbo. I've got a gated boost controller here to go on, that should make it come on a little earlier.
If you pull a td05 from a mitsu vr4 or evo they have a smaller exhaust housing and come on sooner.

im running a moddifed CT26 from a 7M with unknown specs.
pros: huuuuuge power.
cons: by the time boost comes you forgot what you were doing then get the shock of your life
if i did it again id definately go a smaller turbo, mainly cause i drive the thing daily.

Wagon was finished, driven a bit and sold to make way for a VERY quick Toyota project car 
Wagon ran a best of 12.6 or 12.7 (can't remember??) at WSID. The new owner has plans for more power and quicker times.

I had a quick look at it at the nats as it flew past me, sounded real nice, so i'm guessing the new project is very hush hush, all i want to know, Is it another rolla?

Nah not particularly hush hush, but a few purists on here may not agree with the power plant.
It is another corolla and it's the oldest one we've played with yet

Having been down that road, all I can say is don't do it!!! Response is absolutely shithouse  Although it does seem super fast cause you boot the accelerator, wait.... wait some more... then crap yourself when it suddenly screams onto boost after 4k & pins you in the seat
Does nothing useful as a street car. The pick of the bunch for an all round performer would have to be the ball bearing T28 (a.k.a nissan S15 silvia turbo). Great response, and the potential for near 200rwkw figures.

What Turbo. - GT2535 (its a T25 rebuilt to be a GT2535)
What mainfold. - Custom
What computer. - Microtech LTX-8
What you started with,(eg afm or map)
Rebuilt or not. - Rebuilt to standard GZE bottom end, bigport head and cams
What rwkw your getting - 150rwkw @ 11psi (will be retuned shortly after 4AG Alternator and pulley setup)
why you chose to do it that way. - bought it as is, but seems decent to me
any other specs that might be interesting. - Nothing out of the oridinary
and the plus and minus sides of the conversion - + is its fast - is standard driveline is weak (T50 and S Open Diff)
