Hi, was wondering if anyone could tell me what is involved with sticking an M3 engine in a 318ti Sports Compact. My other half has been going on about since the day I bought my car, but I said no until the engine goes (not likely to happen).

But just out of curiosity how hard is it?

Not straight forward :rofl mine was made a little easier by going half way and fitting an E6 325i engine first (no for sale - see Ebay For Sale thread)

325 engine gave loads more torque and power for very little cost. M3 has given me even more of both - but much more expensive.

There is a lot involved going from 318 - M3:

New engine :lol

Possibly new gearbox - although my M3 is running a 318 box perfectly - great ratios for rallying. Max speed about 115mph but great in gear acceleration.

New clutch

New front struts and brakes (ideally rears too)

New DIY exhaust

New subframe

Move battery to boot

New radiator

Fit oil cooler

Change dashboard, ECU etc...

Very pleased with mine, goes like stink but a major conversion by most standards...

Good luck if you try it. I have a contact who provides M3 kits - inc all parts needed for around £2500. Pm if interested.

I put a 325 motor in my 98 318ti sport too. Simple conversion. just drops in and plugs in.
