i've got that extra m20 sitting in the garage, so i was thinking of trying to rebuild it as a budget 2.7 stroker using a 524td crankshaft and eta pistons. it has a ton of miles on it, though, and if it had to get bored out, i'd have to get custom pistons, which would kill the 'budget' part of the equation.

If you can feel a ridge at the top of the cylinder, it sure needs to be rebored. I did build many engines, some with scratches on the wall, some with ridges. You can live with a scratch but not with a ridge. It will eat up the rings or the land into the piston because the ring is not perpendicular to the walls then.

I did race a VW in another life, 1.8L GTI engine, i did open the engine every race, honned the block and changed rings every time. i did it at least 5 times. The block was severely scratched, it eated up some sand (oval semi dirt race). Engine never smoke, no ridge. I finaly sold the engine to somebody, he still run the car, a 82 Scrirocco. He his very happy of the power, bet that he dont know that this engine has revved 8krpm many many times...

    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
