I have an epp fmic setup im putting on with my d1sc. I bought it from another member. The elbow to the tb is a 4" to 3" reducing elbow. I talked to Bob and he said they are designed for the stock tb. It is way to big for my tb though. What did everyone else do?

i thought the 4" was too big for mine when i got it too, but once you clamp it down its tight. granted i just finished my project and havent gotten in boost yet, but after i clamped it i yank on it pretty damn hard for piece of mind and it didnt budge

Cut it where it reduces from 4" to 3", but not too much.

AFASTYZFR1 your setup looks like mine. Was the elbow really big compared to the throttle body? Did you just clamped it and make it tight?

I have the EPP kit. Yea, it was large so it could fit aftermarket tb's also. I just trimmed it to fit. Mine fits snug over tb without clamping it down.
