Hello All,


Forgive me if this is a stupid question, but I'm looking to get ahold of a '75 '02 and had an idea. I'm curious to find out if anyone has tried or knows if it's possible to put the engine from an M3 (any year) into a 2002. If it is possible, what exactly would need to be done and what do you think it would cost? As of now it isn't something I would do, but a friend joked about it in passing and piqued my curiosity.

You'll find this sentiment echoed pretty much universally, unless you are looking to drastically change the rest of the car into something its not the only M engine worth considering is the S14.

Marshall's project thread is a great way to familiarize yourself with this setup.




And one more, a short on Marc's M2 (at least his customers anyways)


EDIT: Haha, dang it, ray's got it covered.

Anything is possible mate. It just comes down to time and money... Im not usually the type to bitch but damn. Use search on something like this. You could probably find a bunch of swap stuff if you typed "BMW 2002 engine swap" into search... If you're asking about specifics that's totally chill. Its probably hard to figure out if an S54 oil pan will clear the 2002 front subframe without custom fab or som question like that. Other than that, Welcome to the forums mate! Jump in and have some fun!

I hate to say "Search!", but goddamn, there are about a million threads on this topic here.  It is commonly said that the S14 (from an E30 M3) can be very expensive to maintain and is getting harder to source (it seems).  The well-tuned M10 is a great engine and can get 150+ horsepower with new cams, bigger carbs, etc. The reasons  to swap to the S14 are (IMHO): Wow! factor, high end horsepower gains, fuel injection, etc.  

I'm no expert, but I've done a little research on this conversion as well. It has definitely been done. Good luck finding a nice '02.  It's a rewarding and frustrating (in the best way) experience.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
