This is my posting on this forum so please bear with me.
My reason for this post is that I’m hoping I can get some help identifying the motor in my 1988 e30 car. According to Realoem.com the chassis is a 1988 eta. The last 7 digits of the serial # are 4321034 which I understand makes it a supereta but the engine and trans don’t support that. I found the 8 digit serial # on the engine but don’t know how to identify it. It’s hard to read but here it is, 22806386. I believe the engine/drive train came from a 325is but need to verify the year and engine type so I can order parts. A few things that I do know is, ECU # is 153, dual valve springs, rev limiter and tack redline at 6500 RPM, 2.5 cast into head (exhaust side between #5 & #6 cylinders) 885*** cast into head on intake side but no real identifying marks on block. Any help would be greatly appreciated.
