Hi All,
So, I'm a relative newbie to the world of e30s and hope I don't get slammed for asking this question. I've tried to research online myself and even called BMW without success.
I bought a 1990 325i Sedan about 18 months ago. Based on VIN and realoem this car is supposed to have the m20 2.5l engine. I'm trying to confirm this is the motor I actually have in my car. The reason I'm wondering is that the head only has 2.7eta on the casting.
So, a couple questions:
What is best way to identify the actual engine? The numbers above the oil pan on the driver side by the alternator are 22166216 but I haven't been able to find a source to interpret these numbers into the engine type and BMW service wasn't helpful.
Is it even possible to put a 2.7eta head on a 2.5l engine? If yes, and I have the 2.5l engine, it seems like I would get a nice performance boost by going to an 885 head based on other posts I've read. Is this conclusion valid?
The car seems way too quick to only have 128 HP so I'm guessing I have the 2.5l, but since I've never driven an e30 I don't have a comparison for my butt-dyno.
Thanks in advance for any help!
