Early Eta's up until Sept.1985 had a compression ratio of 11:1. The blocks of these engines is stamped 27 6KA. From 9/86 the compression ratio was dropped to 10.2:1 and these engines are stamped 27 6EB.
If you mean other specs no idea lol. Im in the middle of doing a Euro piston build.Last edited by Eurotrash727; 07-31-2012, 11:55 PM.Comment

ya the super early etas were special with the 11.1 piston. finding the 11.1 pistons is crazy hard. i found a set one time but i ended up not buying them (face palm)Originally posted by Eurotrash727 View PostComment

Ah so i should just look for the casting mark to see if it is indeed a euro specComment

im confused so if they stopped making the 11:1ratio around 9/85 and they went to the 10.2:1 ratio on 9/86 where does that leave my euro sitting at?
I just went to one of those VIN decode sites for BMW and i found this
Production date 1985-09-02
but on my door it said Manufacture date 5/86
does this mean i barely got the compression ratio 11:1?1986 325e (EUR)
