Okay, I just recently found out the previous owner of my car installed an FC MAF from an rx7. What are the benefits of an FC MAF over the OEM MAF?

allows for better high-rpm (6k+) breathing, that's all.

I could be wrong but I think in the rx7 maf the part that connects to the air filter is round whereas the the oem part for the 1.6's is square. The only real advantage to this is that its a bit eaiser to make a custom intake b/c you don't have to get a square to round adaptor.


I think I remember reading this but can anyone confirm it?

it's worth about 5 hp give or take from about 6.5-7k. It will cause you to run a bit rich below 4k though even when properly adjusted.

You're right about that, but it's not the "only real advantage".

I used a MAF off of a 1993 MR2 Turbo on my 1991 1.6L. I think it might be the same MAF as the RX7. My car ran very strong and I didn't really have to fiddle with it at all. Don't know if they are any easier to find (I had one laying around heh) but it worked.

Oh my bad, I should've been more clear. #-o I ment that fitting the filter eaiser is the only real advantage to the square vs. round.....i didn't mean that that was the only advantage to fitting the fc amf.

Why would I change it?

 

[Muzicman16]

oh. . .lol i misread. . .yea dont change, very worth having it in

 

[dude]

i have one sitting in my 'parts bin' i am going to have a go over the winter when i am bored, it doesnt really worry me too much about the running rich as i have an apexi fuel controller installed so i can turn it down a bit to lean it out, will post results if and when i do it

Better check your injectors, they might be different too.

Why would they be different? The way you put it makes it seem like it's a bad thing. Or maybe I just perceived it wrong. #-o

 

[Greg G]

No I mean the FC AFM is usually partnered with 1.8 injectors, they balance each other out.
