Hi lads,
I know of a wee 318is needing mechanical work, I'm thinking of buying it with the aim of dropping something with more horse power into it.

I was thinking m30 but in terms of cost, ease of transplant etc are there better options out there?

All suggestions welcome

For ease of transplant, I would suggest another M42 or possibly M43 engine.

However, why not be completely different, and fit an M40 318i donk in there? Probably a 'cheap as chips' option, while you rebuild the original M42. winkeye

Tbh I wouldn't entertain a 4 pot :D I need that 6 pot growl, so I should have mentioned an engine with a minimum of 6 cylinders :wink:

Any suggestions on a 6 pot?

3 options 170bhp fuel guzzler m20 b25 , same again but more so m30 of there is 24v's m50 m52 .

cheapest conversion is of course the m20 if being a regular visitor of your local fuel pumps is your thing .

I like the idea of an m50/52 but they spoil the engine bay of an e30 by totally filling it. Still keep looking at them though

M52 is a smaller and lighter engine than that primitive cast iron boat anchor that is a M30. Also has the correct number of valves andf cams.
The M30s one advantage is that it has holes that add up to 3500cc in the middle of it.
