m20b25 parts on a m20b20?

[shaun_89]

Hi, ive got some spare parts from my old 325i track car i was thinking about putting on my 320i.

Ive got the the 325i:
inlet
afm
throttle body

My first question is that the 325i was a chromie so had the earlier management and the 320i is a late spec so has the better management. Is there any differences in the throttle body/afm fitment between these?

My second question is do the ports line up on the 320i head and the 325i inlet?

My third question is that will i see any gain from the larger parts from the 325i? I know 320i lacks low down gunt as it is and i dont want to completely kill it off with larger inlet ports in the manifold.

Thanks

The 2.5 throttle body makes a nice upgrade on the 2.0, ive done the conversion myself.
Theres a how to guide in the zone wiki, just take a look its nice and straight forward to do
