Need help choosing a maf for turbo car
Well I finally got my hands on a notch. It needs some work and its a lot of new stuff to learn for me. Anyway its a 306 with 42 lb injectors and a cartech turbo kit with I believe a 70mm ITS turbo. When I got it it had a draw through lightning maf and the bov open to atmosphere. I know I need to change things around and the car hardly ran before.
I been reading and this is what I am planning on doing. I am going to mount the bov near the turbo and get a blow through maf and mount it in the passenger side fender near the throttle body. What maf do you guys recomend? I was thinking the PMAS pro tube 3in
Here is a small problem though. The piping is 2.5 inch. The maf is 3 inch would it be affected if I stepped up the piping to 3 inch near the maf then back down to 2.5 inch after? I don't know if that will disrupt the air flow causing the car to run weird.
Any help or recommendations would be appreciated.
