Turbo boost?

Isphius · 08-23-2006, 01:48 AM

For the turbo experts, How much hp could i expect from a stock 7mgte(auto trans) with rebuilt head and turbo, Brand new toyota headgasket and torqued arp head studs, Intake/exhaust/mbc, And no other mods except a mk4 intercooler nad hardpipes and as good of gas as i can get? This is all i plan to do untill i can afford an entire extra motor and rebuild. I know i can only get to 14 psi or so before boost cut, But i plan on keeping it about 11-12 just to keep everything safe and unbroken. So basically, Allt hos parts and running 11-12 psi.

You'll hit fuel cut around 11psi, at that point you'll probably be around 240whp.

hmm 240 is still good enough for me. What boost can you run with the lexus afm and 550 cc injectors?

how much boost can be ran without needing an after market fuel regulator?

240 whp at 11 psi? That is only a 10 horsepower increase from stock. Whats with that?

jfunez · 08-24-2006, 02:26 AM

that doesnt sound right......

wasn,t it like 6 or 8 horses for every psi incremented?
I may be wrong but 240 @ 11 psi dont sound right to me.

He said 240 at the wheels. The 230 rating is at the crank. So it is a substantial increase. The stock would be about 200 give or take at the wheels. So im not complaining at 40 extra hp. That would be about 270-280 at the crank. Basically 1jz-ish

That's what I figured, thanks for clearing that up

How much boost can you do with the 550/lexus afm mod? And do you need any other parts to do the swap? ive heard some people need to get fuel computers but some run perfectly fine? i dunno
