Larger Air Flow Meter

Post Sat Apr 30, 2005 5:08 pm

Hi, I'm just looking at some other sensible mods I can make to my '88 325i 2dr.

Already got a fast road cam, ported & polished head, re-map ecu, FSE power boost valve, k&n panel filter in standard air box, scorpion stainless dtm system, but on standard exhaust manifold. All of this was done to the car before I got it.

Been thinking about putting the larger throttle body/afm from a 3.5 on it. Is this a straigh swap and will I need to have the ecu remapped once installed?

I plan to get it on a rolling road for a proper set up in the next 3 months, would be interested to see what power and torque it is making with these mods.

M30 AFM has been treid and tested and seen NOT to work.

Dont waste your time.

cheers fella, saved myself a bit of messing around there then!

I suppose from what i've done to it so far, the only way I can go now is to either go for some fancy throttle body induction system/ bike carbs or more displacement. How much hassle is the 3.5 conversion?
