THE LATER ONES HAVE NO HOLES FOR THE INJECTORS .

THEY DO HAVE A LARGER VOLUME BUT WORK WELL

WITH THE RIGHT PISTONS . YOU WILL NEED TO CHANGE TO

A 2002 CAMSHAFT IF YOU WANT TO RUN A 2002 DISTRIBUTOR .

but again, the head is designed for a specific popup piston. With a flattop, you might get a good turbo compression ratio. I keep meaning to check the piston dome against our heads to see how much it would need to be machined to fit an '02...

used a 318i head on a '75 2002. The old e12 head met the legal definition of toast, what with corrosion into the compression chambers. Got a head without the drillings for the injectors, skimmed it, new valve seals, (I bet the SOB machinist didn't check the guides) and installed. Compression with new rings slightly lower that factory new, but ran very nicely with 32/36 and stock exhaust.

But thanks to the machinist, who had come recommended by two independents, it smoked and likes to foul one plug. Now one of the independents tells me the machinist doesn't like to grind valves, so I guess he didn't, and I have a bad valve or guide in there. And it's all back together. Live with it, mo-fo.

since i am still breaking in the engine, i dont know what the full potential of this head will be. The engine feels powerful, and justwaiting to be let loose at 4k plus. I have had it to 5k for a blip, and i could feel power coming on quickly above 4k. So, right now, I cannot answer your question. I had to use it because the engine was built with 10:1 compression and i have to live in crap-o-la californai gas land. So, as a compromise to avoid knocking and radical timing, i had builder use the 318 head because the larger combustion chambers effectively reduce compression to around 9.5:1 which has worked perfectly with CA 91 octane. You can check out Metric Mechanic website to see exactly which head they use in their 2.2 HIPO engines. A nice side benefit of using that head is that it is a casting date much younger than typical E12, or 121 heads, so chambers were clean(er)( although they clean them anyway, and because of the EFI, the plug threads are fresh b/c plug changes were not required as often as with the older engines. I have a "skunk works" Metric Mechanic cam that is rated at "292", but which road tests at 302. Builder will not release cam info to me - says he is writing article about the cam and they are re-doing web site to reflect the comparisons they ran against the Schrick 292. I still have my Schrick 292, so if after i have broken -in the engine and i dont think i am getting the high end power i expect, I can put the Schrick back in. I will also have a completely redone E12 MM head to put on when i leave this lousy gas state.

    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
