Has anybody heard of swapping a 2.5 or 2.8 6cyl into a 318? I am hopefully going to be buying a BMW soon, and want a 5 speed. It is really hard to find the 325i (4 doors) with a 5 speed, at least on Ebay and other sites. I am also wondering how much a complete engine setup would cost for the 2.5, and if the tranny would match up at all. Any ideas? -JinX

In theory it is possible to do it because the 3 series is developed for 4 and 6 inline engines. So on the 318 there is the right space to fit the 6 cylinder engine, but the problem is the cost that may be very high, and the law. It depends on what is your country.
However in europe there is a factory that puts even the V8 of the M5 in the 3 series!
Another problem after the swapping is that you have to put a more powerful braking system on the 318.
Bye:rolleyes:

what year car are you looking to do the engine swap in?

Obviously you can put a 6 cyl in the 3 series, but the price will be very high. i would keep looking for a 4 door 325i 5 speed before you put a 6 cyl into 318.

Hey, i saw that you're looking for 325i's
well, i have 2 325's. i dont know if this is the right gen for you, but one's an '89 325iX 2 dr, 5 spd. with 180 k miles, white with tan interior 6 cyl... 4700 or negotiable

then i have a '91 325iX 4 dr, 5 spd, 124k miles, power everything, it's a nice blue color, well more like silverish blue. 5500. but negotiable.

i can have it shipped anywhere you want. but you'll have to pay it of course.
