How to id a cam


Recommended Posts

So finally got a moment to finish tearing the head off my e30 donor, and upon closer inspection it looks like someone has replaced the cam in this car. Unless Dr Schrick came stock in this chassis :)


Cant tell you how excited I was to see it nestled in the head, but now the question is what cam is it? Should i pull it out for inspection, or just put the head on the 2.0 block and give it a try? This will be a turbo build and as mentioned before this head is VERY clean.

Those look like 318i pistons- 320 after 79, E30M10.


You need to look on the nose of the cam- you'll probably have to take the sprocket off.

If you google schrick cams (maybe put 292 in, as well) you should find Schrick's website-

it has very comprehensive cam info.  You can, for example, find the base circle, (smallest dimension of lobe), measure the nose of the cam, (biggest dimension)

subtract base from nose, and compare that number to their charts and have a very good idea of what you have....

-Schrick cams have the actual grind on the front nose of the cam. (Dang it, Toby beat me).


-Bear in mind, a hotrod cam is not always best for forced induction.  Generally speaking you want longer duration, not lift, with a turbo.  Additionally, you may want to have the valves tested.  Stiffer valve springs are nice on a turbo engine if you decide to up the PSI a bit.


-Those pistons are stock for your engine.


- Also, just take note that late model M10 cams have the distributor gear moving in the opposite direction.  You can not just slap your 2002 distributor and call it ok.


Good luck with your project!

Thanks gents. Will have to look into the cam further to ensure it will work for what i have planned. Had intended on sending this head out to get a new cam springs and possibly rocker arms - with the lack of machinist around thought it best to get all the things that might be needed at one time - but then the cam was found.

    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
