325i To M3 Motop Swap?

[echi_sene_frega]

hello BMW community, im a new 1994 BMW 325i owner and i bought the car with a bad motor and i was thinking of just buying a better motor than the 325i motor for it such as the 1999 and up M3 motor for it...yet before i was going to purchase the motor i was wondering if i could even do the swap successfully. would the motor fit? would it function properly? what details would i have to work out? how much would it all cost? id appreciate any and all advice you can lend to me. its great to be part of the community and thanks again.

I cant give any advise at this moment, sorry, but I just wanted to say and I am sure someone from here will have the answer. Good luck mate.

here you go, granted the swap was an obd1 engine, but an OBD2 swap has just a few more steps as far as programming.

hey,

I was looking at this swap myself for my 320. I checked it out with my mechanic. He used to work for BMW and he is trained and everything.

Basically it can be done but there will be quite a lot of trouble as a lot of stuff needs to be changed around. Well i guess you can get the new motor for a reasonable price. I mean in enlnad i can get it for about 3000 pound (slightly more than 6000 dollars) but you will be lloking at spending the same amount on top of the motor for the installation.

But if you have the money it's worth it.

Things to consider when doing this:

Whether or not you want an OBDI or II motor, the OBDII will be a bit harder to install as your car was originally wired for an OBDI motor.

Also, If you can afford to just buy an M3, that would most likely cost around the same amount after motor, and install.

The downside to doing this swap is the cost, but also you have to remember (the more positive side) your cars insurance will remain the same, even though it is as fast as an M3, you will be paying for 325i insurance but have an M3 equivlent car.

The insurance benifit isnt one that ussualy appeals to adults, but even if your in your 20's the insurance will be significantly less than that of an M3.
