ponyboy88

starting to get my motor together finally, just hoping someone here would be able to help figure out what i should expect from it, so i can size the injectors. The turbo kit i brought used comes with a blown turbo so i will either rebuild it or pick up another sized turbo if its way off for my build.

Its going in a relatively full weight 89 hatch, either an aod or t56 behind it, car has to run on 93 octane and be street-able.

what i have, starting from the bottom:

383w, forged internals, 4 bolt splayed block,
brodix T1 215 CNC heads,
trickflow r 351 intake, its set up for a 75mm tb, will prolly bore out to 95mm
PTK single turbo kit for 351 with turbonetics t72 q trim .81 ar (turbo needs rebuild)
2.5 in/out intercooler
3 inch down pipe

whats left is figuring out the tranny, tunner, and fuel/air system

thanks for any and all help,
hopefully ill have pics up soon

T72 is to small for a 383 it will work but never make the power it should or could I would be looking at a PT88 if you are looking to stay T4 frame turbo at the very least and there are other much better T4 frames out now like the B/W s360 stuff with large turbine wheels to keep back pressure low. Back pressure is the one problem with T4 frame turbos and large CID

Yea I'd suggest a 78mm. I use a 70mm on my 351w which is perfect. Your motor sounds decently built I'd go 78mm or do a twin turbo with two 70's
