Hi! I was wondering could somebody tell me everything I'll need to buy to do a 95 M3 swap into a 95 325i? Thank you!

you need an s50, a new ECU, and thats about it!

**nghiadeghet** · 04-10-2006, 07:53 PM

Really? Wow. Thank you for the info!
I thought it would take more than just that.
It would be a direct fit right?
I'm new to BMW's. I was always a Honda guy.

yea, i mean, someone may be able to pop up w/something else, but thats basically it, thats all you need to make it work, however you may consider doing some other mods, like suspension, just b/c the m3 engine is probably a bit heavier than the 2.5, might make your weight distribution a little bit off...

better brake's and suspension too would be helpful + exhaust system. Otherwise, you're set.

Make sure to get new engine mounts.

it all sounds so simple doesnt it? lol

good luck with this man.

You need the engine, the ecu, the vanos ecu, the wiring harness and full exhaust.

Brakes not nescesarilly, a good set of brake pads will do the same.

What is a vanos ecu? The wiring harness is the same.. and the exhaust will fit up.. If his ecu is a 413 he can even use this for a 95 M3 engine.. So really he just needs the engine.. Nothing else.

Yup. Just the engine. Since it is OBDI, it should just all be plug-n-play. You will probably need a chip for the S50 though, but that would be a good time in getting a performance chip from TMS, AA, or Dinan.

No chip needed.. The 95 M3 used the 413 and 506 ECU.. which is the same as the 95 325.. But, I would chip it just the same.

Gauge Cluster also.

Hmm.. Maybe only the EU M3 engines have that... they have a 2 ECU's, one for the engine and one for the VANOS.

Why do you need that? Not for the speed reading... You can put any E36 clock in any E36..

**B_w.** · 04-14-2006, 11:20 PM

why do you want to do the swap? you could turbo the 325 and make much more power
