I accidently posted this in the 911 Technical Forum yesterday....
I'm considering using the stock cast iron cylinders, bored to 85mm, and using JE pistons. I've seen this referenced in numerous threads but I have not been able to find much detailed info on the process.
- When boring the cylinders should they be bolted to some type of a torque plate fixture?
- Should I source the pistons and take them to the machine shop when I get the cylinders bored?
I attached a pic of #1 piston and cylinder. (#1 exhaust valve dropped. Head & piston were destroyed. I bead blasted the piston so it could be used for "desk art". The exhaust guides on the remaining cylinders are all very worn.)
- Do you think this cylinder will clean-up when bored to 85mm?
