1rotty 40 Report post Posted June 27, 2011 How well would a 4cyl e36 box work behind my 2.8 e30?? Are the ratios the same as the 6cyl boxes? Any help much appreciated Quote Share this post Link to post Share on other sites
BM WORLD 1283 Report post Posted June 27, 2011 the gearbox will lean over a little if mated up to a m20 block , but otherwise will work ok . 5th gear is 1:1 on all 5spd e36 boxes. so you will be wnating a taller diff ratio like 2.93 to 3.45 etc Quote Share this post Link to post Share on other sites
