no major engine parts will work off a 318 to a 325. and the valance, get one off a volvo. someone did the conversion not too long ago

Go for same year parts from second hand yard. The problem with the 'e' engine is valve size (for a start) and the EMU. Put on all the manifolds you like and injectors that flow enought for a top fuelie and you still have a 325e - running rich. You need the 'i' head and emu/chip.

engine management unit. its the term used more in american cars.
the main problem with the e head is the cam. since theres less bearings, its weaker, so it has to have that lower redline. ever seen a 4 bearing cam on a i6 go over 6k? it gets interesting.
the valves themselves are actually bigger then the "i".

Does not want to Rev smoothly
Downhiller, thanks for the enlightenment
I think we only had the "e-motor" in the 5-series then :dunno:
DJHAYTER, are you getting enough fuel :yikes:
Terrains, I bet you that I can tune a 323 or 325 i to Rev as crisply with amazing throttle response, to beat most modern cars
The trap-door AFM is one of the culprits for making these cars feel sluggish and I would love to convert mine to a MAF, so when I go Turbo...

:rofl: I'll take your word on that. :thumbup: I've been doing some research around r3v, and people are doing a Miller MAF with their programmable W.A.R. chip. Everyone who's done it said the throttle response and sound was amazing. If I had $600 to spend right now, I'd probably get itDownhiller, thanks for the enlightenment

MAF to replace VAF
Problem is that the stock trap-door sends a 0-5v signal to the ECU whilst some MAF sensors have a constant voltage supply & check the difference in current.
i.e. a totally different signal is being generated, which you have to convert for the stock ECU or find a OEM ECU that can handle all stock signals and that of a MAF :dunno:
What air flow measuring device did the late, 93 or so, use ?
UPDATE:
I have just tested another MAF, this time from Toyota and see that it changes the voltage signal.
This means if I can find a suitable MAF to replace the VAF, I can change the signal curve with the Unichip :thumbup:
