air flow meter upgrade for rb20 - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

mini skyline · 17th November 2002, 01:07 PM

Does anyone know if the rb25 and rb20 air flow meter is the same, i need to replace my air flow meter on my rb20, i thought about fitting a vg30 air flow meter but it seems like alot of work for what i want.
basically i need an air flow meter for my rb20 that can handle upto 320bhp, i've done a bit of research but can't find what the standard rb20det air flow meter can handle.

It's borderline on the std unit but the only other option is to fit the Z32 Maf unit, I'd stick with the std unit for now..

also since you've used these pfcs before could you give me a bit of advice, is the pfc worth the effort or should i not bother and sell it on, do you know where i can get standard or suitable eprom for the pfc as its got an unknown rom in it and i'm a bit worried about fitting it.
