4inch Inlet..q45 Or Z32 Afm

[drgnball34]

Ive got a GT3040R for my Neo... The turbo has a 4" inlet diameter.. Since the Z32 afm is 80mm and the Q45 is 90mm.. Would it make more sense to go for the larger one and hence be less restrictive? My power goal is 300rwkw. Even with the Q45, it is still 10mm smaller then the inlet size. Would this make much difference in power? How would the exhuast shop go about fabricating my inlet piping? Use 4" pipe and silicone hose reduces for the AFM?

cheers

My mate just rolled the 4 inch pipe down to the right size to fit the q45 and its all good.

4" to 80mm reducer will do you fine

if you want more than 300rwkw then go Q45 if not, just use a restrictor.

Z32 AFM is good for more than 300rwkw

Z32, no problems.

before the turbo the AFM does not pose a restriction. People will tell you otherwise but its most certainly not
