Not sure what the old one is (stock for a basic 97 318ti) vs. 3.25 one on the M-Roadster. Will my exisiting 4 cylinder have any problems driving it? What would be the gain/loss.
nice find! stock ratio (assuming you have a 5-speed manual) is 3.45 so you'll be even slower than stock! you'll have a theoretical higher top end (assuming the 4 can get it there) ... except for being electronically limited to something around 116-120mph. i'm also assuming that the M-roadster one is a LSD so you'll gain there as well if you have an open diff.
