I recently purchased an 87 zinno 325is coupe that had already been M50 swapped. Well, i recently found an already OBD1 converted S52 with a freshly rebuild head (5 angle valve job, MLS gasket, ARP studs, TRM chip, the works...) motors only got 90k on it. Soooo me and my roommate are going to be pulling out my m50, tranny, driveshaft, and diff, and dropping in the S52, ZF tranny, 328 driveshaft, and 2.93 posi diff. all in the timeframe of this 3 day weekend.
-So far got a new tranny crossmember
-AKG mounts (the ones that are in there would work fine but i prefer non-rubber mounts)
-328(E36) driveshaft to mate to the zf output flange (6 12mm bolts 96 BCD versus the getrag 260's 6 10mm bolts 78 bcd)
-2.93 rear diff, hopefully this will feel nice with the ZF's tighter and lower gear ratio.
-BMW coolant
-Mobil 1 synthetic 5w30 motor oil
-Royal Purple 75w90 gear oil
-New guibo & CSB
-The rest of the usual 24v swap parts (different brake booster, E34 oil pan etc.) I should be able to take off of the M50
We are hoping that's it but please let me know if there is any other parts you guys can think of.
So far the only thing i can think of thats in question is the shifter linkage. When the car was M50 swapped by the PO, he used the Z3 short shifter and i dont know if the linkage was modified to account for the 10 degree rotation.
As far as wiring goes just going to label everything, double and triple check some diagrams, test everything, and just take it one wire at a time.
Cant for the life of my seem to be able to get any pics to show right now so check out my other thread to see how she sits now: http://www.r3vlimited.com/board/showthread.php?t=277382
Suggestions are more then welcome!
Shes getting pulled in the garage tonight to get started so stay tuned for some pics!
