325i Sport Tech 2 Question

[/// KAMI]

Basicly i have a Tech 2 Sport on a H reg and i was thinking of putting in a mtech 1 bottom end and 6 branch manifold and a good camshaft and bigger throttle body....would this keep up with a 2.7? and also how much would it cost for bigger throttle bodys?

Thanks In Advance

If the 2.7 had you on the end of a tow rope you would be OK...

If you're doing anything with the bottom end it's got to be m52 crank and m20b20 rods to amke a 2.8L M20. That'd keep up with a 2.7

my first thought was the Tech 1 Side skirts !!!

I think what he's getting at is the pre-facelift M20B25 had higher compression which was brought about by having different pistons.

what pistons do you use for that then... 2.8 or standard 2.5.

and of cousrse what power gains are there..

how much bhp does the 2.7 have,,,, im still new to the bmw e30's

Depends which "version". Anything from 180-210bhp.

The M20B28 uses 2.5 pistons. It's a stroker.

The 2.7s are strokers, the 2.8 is a longer stroker, but achieves a good compression ratio with some easily available standard bmw parts. Power should be around 200bhp for the 2.8L conversion with a chip to match.
