I'm doing my first turbo build, and I'd like to hear some advice. Here's my define:

B18C1 block
ITR Crank
Eagle rods/Wiseco Pistons 9.6:1
B16 Head
AEBS IM
CTR/ITR Cams
PeakBoost Kit(A/C Ramhorn)
Garrett GT3071
Specs:
50 a/r 4inch inlet

71mm 56 trim wheel

flow: 46lbs/min

max WHP rating: 475whp

Turbine

T2 flanged .86 a/r

57mm 90 trim wheel

Copied directly from site.^^^

RC 750cc injectors
Walbro 255lph
Tuned on Hondata S300

I've been doing some more research, and I'm wondering what spool time would I be looking at? I'll be shooting for 350-375whp.

Also, I've looked through every discussion of GT30R vs GT35R. Should I have upgraded to the GT3076? Or will the GT3071 be a good turbo for this setup?

Up top, I need advice

 

That turbo will be fine for your setup. No need to upgrade since your only shooting for 350-375whp.

 

Well it's more along the lines of 350-400whp pump, more on race gas. Now I know the turbo's good to about ~475whp, so around 400whp on pump is doable, then?

 

looks like a good match to me
