: : : What options exist for hopping up the engine
: : : on a 320i to get around 150-200hp?
: : : The ones I know about:
: : : 1) Buy a 323i
: : : 2) Buy a 323i donor car and install the parts into a 320i
: : : 3) Other options?
: : : Is it possible to install an M3 E30 4-cylinder engine
: : : into a 320i?
: : : I would really like to buy a 320i (used to have one),
: : : but it's just a little too slow to keep up with the
: : : freeway traffic that I encounter. Thanks.

: : Hello,
: : I have a 1502 with 2,0block/E12 head, 300° BMW-cam, dual 45dcoe weber, headers, compression 10,5:1 with 180hp @6600rpm. The engine runs good from 2500rpm up to 7500rpm. Real power over 4000rpm.
: : With a 304° Schrick cam and higher compression you can get up to 200hp. Runs quite good on street.
: : When thatīs not enough, take 48dcoe and a 316° cam. But the engine runs quite bad under 4000rpm.
: : (not real for street)
: : To install the complete 323i tech in the 320 is a good solution, because the small six is quite powerful and runs very smooth. With CIS and 2,3 you can reach up to 200hp. I have a 2,7l engine with CIS and I have about 230hp.
: : To put the M3 4-cyl.engine in a E21 is not a real problem but quite expensive.
: : Here in Germany we have E21 with M5 engines (3,5-24V to 3,8-24V) or big six turbo engines.
: : I know people who put V8 (740i) and V12 (750i) in the BMW E21/E30
: : Everything is possible (when you have te money...)
: : Greetings Oliver Hitzel (Germany)
