930 Piston rings/cylinders
We are rebuilding our first Porsche Motor, of course it had to be a turbo, that has been sitting for 15 years.... We've gotten it apart, sent necessary parts to machine shop, for cleaning, polished crankshaft, replaced studs, valve job(replaced one valve for poor seating), everything else looked good.
Cylinder #6 had 2 broken rings, no damage to the cylinder, piston or the like. Cylinders don't even look worn.
These cars had Mahle rings/piston sets factory, the only place i could locate the factory chrome rings was from Porsche. Is this a sound investment? Does it matter if we go with the Goetze sets? Trying to keep the car as stock as possible.
The car will be fittted with high flow exhaust and updated turbocharger/intercooler. We just don't want anymore trouble than we've had to make this car as right as possible! Hilarious, I know.
