964 engine rebuild 11.3:1 compression
I'm beginning a rebuild on a 92 964 race engine. I would like to build to 11.3:1 compression. I appears that we can not get there just fly cutting the heads. We are starting with virgin used heads that will completely be rebuild will competition springs and new Mahle p's&c's.
Question
1. Can we cut the cylinder and if necessary machining the piston domes to get 11.3:1 without compromising the piston dome or ring land strength or integrity.
2. what deck height is reasonable for this application
3. Will the chain tensioners be able to accommodate the
change in height of approximately 1mm
Thanks Bob
