I am rebuilding my 2.0L....again and want to know what folks are running for compression ratios. What compression tester readings are you getting at first rebuild and then once the engine has "settled"? How long did the engine take to "settle"?

The reason for our rebuild is:

cyl #1 110lbs
cyl #2 115lbs
cyl #3 110lbs
cyl #4 45lbs

Thanks,
Chris

A syringe and a piece of plexiglass cut for the head with a hole in the middle.

Gregs numbers are "illegally" high. Even with Euro P+C's we dont get that number unless the heads have been shaved down "alot". Meaning not within the spec of the rules. I have seen 140.. but only when we had what we fealt where illegal heads (for SCCA and PCA).

I still think 250 is too high on the oil temps (especially with 2 drivers)

Stock Beru wires.. or Magnecor's. MSD wires on the carb'd cars (8mm)
