Hi,
I was wondering if anyone can help, I have a M20B20 currently in the car that's given up so am replacing with a M20B25 engine. Will the MAF work from my 2.0 engine on the 2.5 as it seems very difficult to find one for the 2.5 engine.
Any help much appreciated.
M20B25 MAF ?

DONT QUOTE ME ON THIS, but I have a feeling it won’t work.

You need a 2.5 afm. It will run, but the 2.0 afm makes a 2.5 run on the lean side

Ok thanks for the information, it does seem super hard to find an AFM most of the obvious places have them discontinued
