so Im about 2 (or so) weeks away from my supra being driveable again. I blew the HG (of corse) and wayyyyy over heated pupra so bad the pistons expanded and rubbed on the cyl. walls.. so i decided on a full re-build.

so my question is what kind of power can i expect with the following mods.

completley re-built motor.
borred .40 over
eagle rods
arp rod bolts
je pistons & rings
chevette 77 berrings (main, rod, and thrust)
new oem oil seals
completley rebuilt head
MHG
ARP head bolts
intake
full 3" turbo back
hks 3000 pipe
cooleze turbo intake pipe
stock turbo set at 15 psi


thanks for your help and YES i am going to upgrade the turbo... when i get the $$ but i think im going to do a ffim, intercooler, ic pipeing and fuel system b4 i do the big turbo.... probubley endup doing a 60 trim..

From what I see you don't have any fuel mods or anything to prevent fuel-cut. So that 15psi may not be achievable on the stock turbo and electronics. My guess would be around 300-340 at 13-15psi

Shimming the wastegate will not change the level of fuel-cut. It will increase the pressure which your wastegate opens, and hold boost better at higher rpm rather than it falling off towards redline. Do you have a boost controller, because you probably won't see 15psi just from shimming, but it might help you hold the boost especially with a mbc.

I only see an intake and exhaust as your mods for increased power. And the running 15 psi obviously, but without fuel that may be hard to do. A rebuilt motor will not increase your power will it? If so, then I will have the same numbers and they speak of as well. Can someone chime in and confirm these #s?
