Uhh if you're really serious about this go buy yourself some really good stuff (ie single malt) and brace yourself since it's going to be very hard.

Unless you're blessed with a Gates sized inheritance and can buy one of the schnitzer or alpina 16 valve heads for the M10...used in formula 2 and the like (I believe called the M12, Mark care to comment??), you are looking at using an S14 head.

Now that is NOT the nissan s14 favored by rice racers worldwide...that would be the BMW s14 head used in the e30 m3 (1988-1991 in the US, 1987-1991 worldwide) and perhaps one of the winningest touring car motors of all time.

The only problem here is that the oil drainbacks from the head to the block don't match and there are some other problems associated with running the chaindrive to the dohc's. That is to say it hasn't ever been done there are some drag BMW 2002's in europe running such a setup abet turboed and nitroused as well (1000+ hp). It's just gonna take some fab work and time and money.

BTW, the heads aren't cheap...I should have picked up an s14 engine with a blown block for 1k from a racing buddy but I hesistated and lost the deal. Oh well like I need more engines in my garage anyways. The swap isn't popular since most people do the whole S14 to 2002 swap like coop and nick in the UK. The only reason to stay with the M10 block is supposedly it holds up better under extreme boost.

Some of my friends want to an opposite frankenstein. Use the s14 block and an 18i 8v head and make a huge overbored M10 motor. Just because you can overbore the s14 to larger bore diameters than the m10. Weird but some people have done it as well.

Cheers,

Bernard

    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
