antil33t 90 Report post Posted October 24, 2012 (edited) You can't, well not easily... the M3 has six throttle bodies, the M50 has one. E36 M3 S50B3x M50 Edited October 24, 2012 by antil33t Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted October 24, 2012 Yeah I don't think they fit straight on.. Could be wrong. Long time since I've had an m50 lol But I remember kerry did something similar with M3 throttlebodys on an m52 (which has the same intake bolt pattern) http://www.bimmersport.co.nz/forums/index....=30332&st=0 Had to make an adapter plate though if you flick through..

thorburn 121 Report post Posted October 25, 2012 Will not bolt up. You'll need to make an adapter plate, modify the oil filter and the tps to get it to fit. To get it to run you'll also need to conjer something up whether it be a standalone or remap Quote Share this post Link to post Share on other sites

thorburn 121 Report post Posted October 25, 2012 You could turbo it for around the same price and get plenty more power. Quote Share this post Link to post Share on other sites

antil33t 90 Report post Posted October 25, 2012 yepp definitely an s50 i am replacing an 400k s50 with a 20k s52 Why? Why would you even bother importing a crappy USA S52? Quote Share this post Link to post Share on other sites

Greg111 13 Report post Posted October 25, 2012 Wha? Were they really 3.2? Thought they were a 3.0L iron block. M52 had the alli block. Quote Share this post Link to post Share on other sites
westy 614 Report post Posted October 25, 2012 Their S50 b30 was the early M50 mota. The S52 b32 was their later M52 thing. All their M52s were iron except Z3 (some S.A. M52s were iron too apparently). Train spotter out. Quote Share this post Link to post Share on other sites

M52s were iron too apparently). Train spotter out. the 3 litre USA only M3 engine is a S50B30US, and their 3.2 litre version is called an S52B32, our proper engines are S50B30, and S50B32... the throttle bodies require a tapered adaptor plate, a modified oil filter housing, and stand alone ecu to work on an M50/52, and in doing so, leaves injector bosses in less than ideal location, you will only gain 3 or 4 rwhp, but throttle response is improved, there is a guy here that did it, then turbo'd it later, and has since removed that motor and fitted an S50B30 and is finally happy...
