I just looked up some codes on Art Glenn's site. Says..... EVO II Mar- May 88 code is 234S1. But 'Late Model 215 bhp' Sept '89-Dec'90 is 234S2...which is the same as Cecotto/Ravaglia (215 bhp versions)Apr '89- Jul '89.
I'll check what my engine says soon.
small details who are different.
I send the informations to Rasmus perhaps he can translate it for you in english.
I have the documents from BMW Motorsport.
The most EVO2 have more than 220hp
Most of them between 225-230hp
I'll scan the details tomorrow an send them to Rasmus and Adwo
..is the addition of the catalyst. I know cos I checked this when I got my late model (215 bhp) car....The cylinder heads have a number stamped on them ( can't remember what it is and it's too dark and cold outside for me to go and check now). I cross checked them against my friend's car which was an EVO II.
BTW my car has had the catalyst removed....perfectly legal here in the UK :o)
I´m currently stationed in Kosovo, and i just found a real battered M3 downhere, i bought the interior from the car(cheap!!)and i´m now thinking about buying the engine, my own car back home is a 195 Hp 1987, but this is 1989 so the engine might be a 215 HP, and i could use that for a project. My question is what ís the difference between the 215 Hp "standard" engine and the non-cat 220 Hp evo II. Any detailed info is appreciated.
The difference between the 195 and 215/220 hp versions:
48 mm throttle bodies
264 degrees inlet cam
inlet channels enlarged to 28 mm
