what engine ?

[fastdave]

Thinking of a engine 4 tourer does anyone know of 2.5 or more that puts out over 280 or 300 bhp thinking about a z3m engine approx 320 bhp?just interested in yr ideas cheers dave.

lots of options with the only limiting factor being how much cash you want to spend.my non bmw engine conversion has relieved me off over £7000+ so far.

As fuzzy says theres so many options its a 'how long is a piece of string' type thing, do you want it naturally aspirated or forced induction? (turbo/supercharger), both are possible from bmw's own products.

E36 M3 non evo engine 286bhp
E36 M3 evo engine 321 bhp
Z3 M roadster 321bhp
E34 M5 3.6 315bhp
E34 M5 3.8 340 bhp


Take your pick for normally aspirated

Or you could buy a proper engine like an S14 and spend loads of money for the desired HP

E46 M3 engine is also a possibility!

Thanks guys idealy i want naturally aspirated bmw power and non stressed meaning it puts out this power as standard i just believe this would be economical than trying to build a 2.7 or 2.8 ect

its cheaper/easier to build a 2.7/2.8 than alot of the engine conversions esp s50 imo.. the s50's are hardly none stressed either, @nearly 100bhp per litre
