BenEvans 0 Report post Posted September 22, 2009 hey again. as i mentioned in my last post i have just done a 2.5ltr conversion into my e30. the original car was a 1990 320i auto. the new engine is a pre facelift 2.5 with facelift intake/ exhaust manifold and all the electronics including the motronic stuff. also with a 260 manual box. (and obviously using a facelift 325 ECU) i just need to know a few things before i go any further and hope i can get some help. 1. does the facelift exaust and intake manifolds fit exactly onto the older block? 2. can i use the facelift 2.0ltr Air flow meter and throttle body from the original engine? and is there anyone elce on here who has done this conversion like i have with the older block and head? if so did u come across any problems? Cheers Guys Ben Quote Share this post Link to post Share on other sites
BM WORLD 1258 Report post Posted September 22, 2009 use the later model loom and sensors front hub . you will need a 2.5L afm i think the old one will do . a 2.5L afm . the old 2.5 inlet manifold is ok . and you will need a face lift 2.5L ecu . can also get one from a e34 525i m20 .

Guest FrantiC Report post Posted September 22, 2009 Are you using a motronic 1.3 motor setup motor?? 320i throttlebodu does not fit the 325i intake manifold. Exhaust manifolds and full exhaust WILL bolt up, yes. AFM will work, but you best get the right one for the right engine capacity. Quote Share this post Link to post Share on other sites
Gus 5 Report post Posted September 22, 2009 off the top off the head you need the facelift loom (you might be able to use your e30's) and the facelift cooling system (again, maybe the same). I haven't done it for a while so there might be other stuff Quote Share this post Link to post Share on other sites
