I am doing this swap right now with my 95 525iT. The weak link in your swap may be the transmission if your 95 has a Getrag 5 speed. The S52 engine is used with a more robust ZF 310 or 320 5 speed manual box. The ZF is longer than the Getrag and will require a shorter driveshaft. The 89-92 E34 525i came with the ZF 310 box. I bought an S52 with ZF gearbox from Zionsville Autosport 2 years ago for $3250 and it has been sitting in storage because other things came up that were higher priority. I am finishing the swap this summer.

You will reuse the oil pan, intake manifold, fuel rail, wiring harness, ECU, dipstick, and some other misc parts I am forgetting right now. You will also need a chip for the ECU to properly run the engine. Turner Motorsport sells one and The Racers Edge also sells one. I did a lot of research before I tackled this and have saved useful posts from places like Bimmerforums. Send me an email message and I will respond with PDF files of all the info I found about the swap. mda185 at optonline dot net
