I bought my 914 on eBay (I know, stupid, but let's move on) and the owner said it had a Big Bore Stroker 2.2L engine, upgraded from stock 2.0L, freshly rebuilt. The mechanic who went over it, adjusted the carbs, and fixed some other issues said that because the compression was 140# in the cylinders, it could not be a 2.2. He said it would need to be 180# or higher in order to be a 2.2, and he couldn't say for sure unless the engine was torn apart, which of course I'm not going to do. I've taken different PCars there for over 20 years, and they have a very good rep in the St. Louis with the Porsche crowd, so I trust him. Any thoughts on this issue?

Hmmmm.... I'm no expert, but a "stroker" engine is an engine that has been built to increase power by adding more to the stroke (different crank resulting in piston travel increase) rather than the bore (piston size). It's possible that you have stock P's and C's and a longer stroke crank, which would mathematically take you higher than stock, to 2.2. The compression ratio doesn't have to change when the engine is stroked. Shorter rods can be used, the deck height can be adjusted, etc. As you said, there is no way to know without tearing it apart, but DON'T (IMG:style_emoticons/default/biggrin.gif) !!!
