roger 0 Report post Posted December 17, 2006 Any suggestions for engine mods for a 1978 320i? I am thinking na with biggish cam and either 45mm webers or converting to efi. Quote Share this post Link to post Share on other sites

bravo 34 Report post Posted December 17, 2006 Agre although a 78 320 - that's not an m20 motor is it? It would be the 2.0L m10 with Jetronic fuel injection???? Webers would sound bad, and it would go a bit better. Still m50b25 in an e21 would be cool too. Quote Share this post Link to post Share on other sites

bmwsparkle 3 Report post Posted December 17, 2006 if its the 6cyl model, dont bother, they have very little torque, used to own one. Quite gutless. 4cyl, then go hard. Cool motors. Quote Share this post Link to post Share on other sites

bravo 34 Report post Posted December 18, 2006 (edited) It's a '78 so should be m10 (4cyl) They've been turbo'd before too if you like a bit of forced induction. Edited December 18, 2006 by bravomikewhiskey Quote Share this post Link to post Share on other sites
