B16A2 Turbo Sizing Question
So I have been researching the crap out my build and I am still putting together pieces here and there.
I was thinking of running a GT3076R Turbo with a 0.63 AR but I was looking at the compressor maps and think it might not work out for my car. Should I run the smaller GT3071R because my engine is a little closer to the efficiency islands on that map, or is the 3076R going to make more power while still remaining close to the 3071R's low end spool up. Compressor map links below...
I guess I am just worried about the turbo surging before it even hits the efficiency islands...
Looking to run 10psi and make anywhere between 300hp - 400hp
A few details of the build:
B16A2 9.0 CR, Portflow Headwork, Crower Stage 2 Turbo Cams
Full Race Turbo kit
AEM Fuel Setup with 550cc injectors
hondata s300 dyno tuned
so on and so forth
Many more bells and whistles so if you need any more information on the setup, just let me know.
Looking to do this right so trying to get as much info as possible. Thanks in advance!
Here's some info to help you read the compressor maps...
