Just thinking a loud here gents...

1) 2.0 M50 - Would upgrading to a bigger T/body as well as the 525/2.5
MAF bring more power?

2) IF using the 2.5 T/body, The MAF from a 2.5 would need to be
rewired ? IS that advisable?

3) Use 2.5 T/Body - keep original 2.0 MAF ? Any good ?

Your advice / feedback appreciated.

Cheers
Dom

p.s. I:m currently running a 2.0 Euro Spec M50.

Your intake tract is the same as a 525i (actually your throttle body
MIGHT be smaller, I'm not certain) and it makes 42bhp more. So your
intake is not a limiting factor.

For a MAF upgrade you'd need M52 parts and the electronics are a big
problem in this regard.

A used M50 2.5 would be your best bang for the buck.
