///MPROVD 131 Report post Posted August 28, 2012 Get hold of Ray (HellBM), he will sort you out with the right stuff or will do it for you (for a fee of course..) hey yes i did ring ray with a quote of 2300 im not sure is this includes gst i wanted to do myself for the experience as well as the savings which based on this quote i could do myself alot less est a kit to be 1700 ish but getting it done is still on the table it all depends on the advice you guys give me about the problem i may encounter my main concerns being the ecu and the diff if this will effect my response and speed accuracy Quote Share this post Link to post Share on other sites
westy 614 Report post Posted August 28, 2012 I'd be impressed if you could do it for $1700 with ZF. Whats a ZF worth these days? Is there a tag on the diff with a ratio on it? Quote Share this post Link to post Share on other sites

BM WORLD 1283 Report post Posted August 28, 2012 (edited) 325i normally just have the getrag box , which is fine , i have one from a 93 325i in my 328i with a supercharger , had no problems with it. easy enough to sort wiring , only have to join 2 wires together so it will start. and 2 wires for the reverse switch . pull out the fail trans light from the cluster if it bothers you. diffs can eb changed if you like factory 325i with jatco i think use a 3.73 ratio?? will be quite revvy , mayeb change to a 3.46 or 3.15(factory 325i manual diff ratio) etc have done a few conversions over the years just finished off doing a couple in the last few weeks etc. or just buy this one. http://www.trademe.co.nz/Browse/Listing.aspx?id=508464853 Edited August 28, 2012 by Brent HARTGE535i Quote Share this post Link to post Share on other sites

westy 614 Report post Posted August 28, 2012 Pretty sure it's a 250 Getrag. The others sit at a different angle. They are usable but a bit of dicking around which you probably dont want to do, considering it's your first etc. Quote Share this post Link to post Share on other sites

m325i 709 Report post Posted August 28, 2012 The diff thing isn't too bad. Its more like a jappa at about 3k on the motorway. I'm used to it now and quite like it. I would only bother changing it if you do long commutes or for LSD. Quote Share this post Link to post Share on other sites
