NE1 use multipoint fuel injectors from 5-er to M4x or M5x ?

[DKBMW318]

I was told by a mechanic that the fuel injectors in M4x (the 4 banger) and M5x (the 6 banger) are one point.

The injectors from 5-er (especially M6x/V8 on 530/E34) or 7-er are multipoint. And the trick is they fit the 3-er motor !

I've never tried this but he said it gives more power but bad mileage. Anybody ever/wanna try ?

You can buy aftermarket multi-point throttle systems for the 3 (not cheap though)... the only problem is passing the clean air laws. Here in CA, it is ultra-illegal unless for track use. Dont know about any other states - but your location says Indonesia, so go for it!
