Carbs may give a little more BHP,

But may also give lots less, run badly, use more fuel, be less driveable, harder to start.

You sill still need a ignition control system as well.


I would only consider it if.

1) Going from a single carb
or
2) The stock ecu setup has a complex imobaliser.

Looks a good one. A lot of work is already done

Didn't realise that the 18i was a SOHC engine. Not the early / mid 90's version then?
Just how heavy is that motor (as a guess)
I had always assumed that BMW units were seriously heavy things.. too heavy .. are they?
Also how tall is that engine.. as in how much above the top frame rail?

thanks.

For what it's worth I think Twin is spot on with his comments. There are numerous reasons why manufacturers have abandoned carbs for years now. I know it's mainly to do with emissions but bad emissions come from less than perfect running - the same thing that causes loss of performance. If it's a challenge you are after then going the throttle body route may be a better option.
Whatever way you go have fun doing it
