hi people. i need help

i just got my 12at rebuilt.
extend ported, new housings, and all new seals, springs etc etc.

now, i want 160rwkw's, or 215 rear wheel horsepower.

can some one give me an idea on what modifications I have to do?

I'm only running the stock turbo (good condition) and stock 6psi of boost. and a s4 rx7 front mounted intercooler.

thanks in advance guys, really appreciste this

thomas.

 

how much power does it have right now in hp?

 

intercooler and about 10psi might do it.

im not super familiar with 12at

what is the size of the turbo?

 

stock they put out 165hp i believe? I was tempted to do that swap myself until the car i was gonna do it to was bought out from under me... *sighs* oh well

 

I plan on doing that swap one day myself. Would be nice to have a 1st gen 12AT,2nd gen 13BT, and 3rd gen 13REW. Hell if I was rich enough: RX8 with 20B


Anyways, back to reality. What size turbo is the stock one comparable to? You have 2 720cc injectors stock right? Might need more fuel than that to get to 215rwhp.

 

ok, i just want to fix up some things.

i have 2 x 880cc injectors, i believe these are good up to 170rwkw before they reach full duty cycle.

the turbo is small, i'm not sure what i could compare it to but running 12psi+ from it, is going to kill it. its oil lubricated and cooled.

yes the 12at's produce 165 flywheel HP with 6psi and no intercooling. I cannot say what i am making at the moment because its just been rebuilt, and i still have to do 1000kms (600miles) not revving over 4000, then after its done, it will be dynoed at 10psi and 15psi.

so, saying that, can anyone give me some advice?

i was thinking:

3" zorst and down pipe (dump pipe)
custom turbo manifold and s5 turbocharger running 10 and 15psi.

 

I'd suggest a hybrid of some kind. Using a S5 turbo would work well with a larger compressor wheel/housing and a 360 degree thrust bearing.

 

throw your 12a turbo away, or hybrid a later 13b turbo onto your manifold. then get it redone with a big compressor.

 

go 4 a dirty big turbo, up the boost....or......you could always supercharge it??!!

 

cheaply, it could be done with a bit of cheater-gas

sorry

But to get the most out of the engine, make sure you put a "performance" air filter and exhaust on it (with headers as well).

Then you start getting the expensive parts.
# Intercooler
# bigger injectors
# bigger turbo
# possibly a piggyback ECU
# water injection
# lowered compression rotors

That's all I can think of now, but your best bet would be an intercooler, water injection, and the bigger turbo

 

Just swap the S4 or S5 turbo on it. They can easily hit this number. As long as you can get the fuel there and keep it from pinging you should get it quite easily.
