Engine/Transmission (1994 - 1998) Critique my recipe- Need advise

[NCovey]

I am looking at doing some serious(to me) bombing on my '96. I have what I think is a good recipe, If you have any advice or corrections, I would really like to hear them, so here goes-



Already have installed-

KDP tabbed

Gauges

215 pump

SBC Twin disc clutch

4 inch downpipe into 5" into 5" stacks

6-speed



Planning on getting-

o-ring and 12mm studs

a good cam-not sure who's yet

ATS 3 piece manifold

HTTB2 turbo

370 injectors

delivery valves

3K GSK

#5 plate

Intake system to meet the needs of the Turbo



Is there anything that I am overlooking, or something that won't work? Any input is appreciated. I am looking for a streetable 500+ with the possibility of light towing. Is this possible? Thanks in advance-Nicholas

No one has any input?

i would go with a bigger turbo. htb2 is a good turbo but i think you are going to have to much fuel for it. looks pretty good other wise.

Do you have any recommendations? Should I find another turbo, or would cutting the fuel a little be a more dependable option?

Skip the 3KGSK and go for the 4K with the 60 pound exhaust springs.

You'll need atleast the killer B2 on that setup, I'm not sure about the SP66 I've heard that the compressor surges on them but of course that was on 24 valves. Either way definitely go with the 14 housing.

I wouldn't go with 370's, go with DDP stage 3's they will keep your EGT's down more than 370's and they are the same HP. I know they are twice the price, but with 370's you have to run more turbo than necessary to keep it cool... . more lag with bigger turbo and not as streetable. Since you said you want to tow a little bit I would think cooler EGT's and the least lag possible are a major concern.

I don't know if it's a good idea to run a 5 plate on a 215 pump, I'd go for a 100 plate... thats a 10 plate with no top end defueling like a 0 plate, hence the name 100.

I recommend a #10 over the 5. % was designed for the small pumps. Add some timing, ported head, cam, to keep egt down, good for 500+. I did my own head porting and used the cam profile I co-developed with Lawrence at Diesel Dynamics. Oh, and don't waste money on delivery valves. I made 800 hp with the stock 181s.
