71erE; When you get your engine back together I would also suggest that
you get it dialed in on on a dyno. I've got a 2.0E with S pistons, which is similar to the configuration that you seem to have. The difference is that the 2.0's had smaller valves, a different combustion chamber shape and of-course a smaller bore. As cmcfaul alludes to, you'll need to adjust (ie. retard) your ignition timing some unless you want to burn through a piston. But too much will introduce a whole new set of problems. Essentially the window of acceptable timing will have shrunk since you're increasing the CR. It's best to know where you stand rather than guess and melt a piston as I have in the past.
