So an engine with a 121ti head has what kind of pistons?

The chart is nicely done but is incomplete and might mislead novices.

By exemple. For the 121 head/Tii, it only lists the 10:1 piston which was Euro only. US had the 9.3:1 piston with a different deck height. A novice would think he has a high comp piston as in fact he would only have a regular one.

Same for the e12/Tii, it only lists the 9.5:1 Euro-only piston. Didn't the North American Tii only had a 9:1 piston?

I think the chart is a good start but needs a bit more specificity.

    BMW Neue Klasse - a birth of a Sports Sedan

    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
