no extra power, mostly appearance/comfort. the sports came with power everything, 13 BC, light mirror, sport seats, LSD (4.10 or 3.73), and premium sound. we never had the m40/4 engines (thank god), only m10, m20 (b25/b27) and m42. i would LOVE to see your car sometime. i'll be here most days from now until mid september. i'm setting up a mobile/handy tomorrow. aber es ist nicht original. ich baute es in meiner garage. wow, SO many things to do here! thank you all for the suggestions! thank you! we have both the 325i and 325is, although the sport is a little uncommon. all of our facelift 318s had m42s. no m40b18 stuff :P did the 88 eta have the 8.5 CR/885 head here? we never got the high CR non-kat pistons like you did here. i'd love to take a set back.
