What is my engine?

[Gawernator]

This is the part number on the .. cam tower(?), I believe, where it says PORSCHE and the firing order. 944.105.250.6R From google searching I get basically three hits, one is a German eBay ad of a used one for sale, something in Swedish and then an old PP forum post about the same number asking if it could be a euro model. So, is it possible I got a euro engine in my 944? Not sure if that's good or bad. Or a euro head anyways. I know the old Head was cracked, and knowing the cheap PO that's probably all that was replaced.

Try a compression test, if significantly higher than the US 944 (IIRC ~150psi) then maybe...

The engine is best identified by the engine type and serial number stamped on the block, on most cars near the clutch bell housing. Of course, that doesn't mean that the engine has not been rebuilt with different components from what was original to that engine.

I'll go look for that.

Cam covers and heads are the same regardless of Euro or US specs. If your engine number starts 43...... its a US spec, if it starts 41...... it's a ROW spec. Highly unlikely someone fitted Euro pistons to a US block but I did so you never know
