Hello,
I'm currently rebuilding the top end on my 79 911Sc with 9.5 Forged JE Pistons with original German rings. I'm coming up with an end gap of .011 (with reconditioned cylinders) which is on the high end of the Porsche specs. JE recommends a gap of around .004 per one inch of bore which comes out to .015 with there rings.
The guys at EBS Racing say go with the Porsche specs. I guess I'm worried if the gap is to small at .011 and if they close up, I'll be doing another top end. On the other hand, I don't want to lose compression by increasing the gap more than required.
I'm running the stock CIS injection with the Web Camshaft 20-21 grind.
If you have any comments on this subject, please let me know.
