91 318i with 325 engine???

[littlemotor1337]

Hello guys,
im thinking to swap a 325 engine in my 1991 318i and i want to have your suggestions. thanks

Depends on what 2.5 you want to drop in there. Are you going for a M20 or a newer model engine? Definetly for sure you have to do the wiring harness also but also depends what you want to get out of it.

and can u tell me what which is a m20?(im a little bit newer in bmw car =D)

[elsabor67]

M20's are the factory engines tha E30's (325s) came with until they changed to the E36 body in 1992. Decent power but depending the mods that you do to them. Most people either keep their M20's or upgrade to a newer engine from a E36 325 or above.

so im better to think to put a newer 325 engine in it?

yeah pretty much. The swap is so common you can find plenty of resources on how to do it, you get better power from an M50 than an M20, and better gas mileage.

can u tell me how much will cost me the swap of a 325 engine m50 in my 91 318(approximatly)

I would also suggest an m50 swap over the m20. That or buy a metric mechanic m42.
