Will an 850 fit in my 325?

[Yazz325Ci]

Hey all,

I found an 850 engine and tranny (automatic) for sale for $1300 at a scrap yard. It has a 6 month warranty with it so I'm tempted to buy.

I'm just curious to see if it will fit in my '94 325Ci with a little restructuring. My neighbor who is a pretty experienced mechanic will help me do it. But first I want to know if it's been done before and if so, how?

Thanks,

Yazz

You can do it. Just yesterday I saw an 850CSi kit for e30s on sale on my German e30 platform

yeah, you can always do it...

but how many parts are going to have to be custom made for the project?

do it but ditch that auto!

Yes, but the m70 is a horrible engine. It's electronics are a nightmare ... electronic throttles, 2 computers, a tranny computer ... it's complicated as shit. That and it's not really a huge improvement over the m60/m62. If you want to swap a large engine, find a m62b44 out of a 540 and swap that. Almost the same power and a lot easier to deal with.

Dude, that engine has two ECUs. It was basically two 6-cylinder engines posing as a V12. I would be scared to do a swap with it
