Could be carbon buildup bosting the compression, but either way 200+ is good in anyone's language. My car runs 10:1 pistons and a head shave to get 10.5:1 and my comp figures are 215 all round.

160 is fine too for your bro's NA6. Factory specs for NA6 are 190 new and 135 buggered so it's nicely in the middle of the range.

his is a 90 manual, so it'd be 9.4:1 8)
