I see. But how will the older computer work? Do the newer ecm's fit in the older cars?
Like already mentioned the later models are a much better base to start. Newer engine with the recipient pcm and wiring...

boy, i've learned a lot in 3 months.
i just bought hptuners this week. i hope to get it on my laptop and testing this weekend.
it turns out i designed a custom aluminum intake for clubgp guys.
i'm working with a top engine builder to develop cnc ported 3800 heads. i/e cfm at 28" water on a superflo 600.
.100 80/54
.200 133/109
.300 184/141
.400 215/169
.500 223/177
.550 232/178
this is with 1.84"/1.52" valves. he still has some chamber work to do - we'll see if we can get it above 240 cfm. i like an exhaust/intake ratio around 75%. small exhaust ports help spool turbos, and let the engine accelerate faster.
as far as turbos: the 35r wheel is up to 80% efficient, and up to 65 lb/min. the p trim t04 wheel isn't a good match down low. turbonetic's f1 wheel is better. they have an f1-35r with dual scroll housing, and dual ball bearings. it should have near instant spool with stock tc, and 700 hp potential.

the cam will be custom designed. however, it will have ~206° duration, and at least -18° overlap for stock idle.
my goal is 500+ whp on pump gas, no lag, and flat power curve. the porsche gt2 makes 530 hp @ 6500, and 505 lb-ft from 2200-4400.
nocutt, do you have a t4 p trim turbine in a t3 divided housing?? the borg warner s200 does that.
i've been planning to run a divided t4 housing. that would change quite a bit.
Have you decided CONCRETELY what compressor and respective hot housing you will like to run?
i assumed you had a divided t4 housing...so i was close to buying an F1-35 with .70 a/r divided t4 housing from full-race dot com. i probably would have be fine with that.
knowing that you use a divided t3 housing, i'm considering the borg warners again. specifically the S258, a 58 mm compressor (80.4mm exducer), divided t3 .83 a/r, p trim t04 wheel from bullseye racing dot com. i expect spool with to start <2500 rpm (NO ONE can give me an approximate number) which is perfect for my stock torque converter.
on a late model supra, and .76 a/r non-divided housing, the S258 made 588 whp, with 'good' spool (he used it to autocross). my ported heads will flow within 15% of stock 2jz heads for similar hp, and my exhaust valve is much smaller for even better spool.
