Euro P&C's?

What is the difference between 2.7 p&c and "Euro" 2.7 p&c?

Thanks

I think I looked this up recently. There is no Euro P&C for the 2.7. There's the 911S and 911 pistons which have different compression ratios. The USA vs. Euro argument comes out when you're talking about 3.0 and 3.2 engines...

P.S. Unless, you're talking about the Euro Carrera MFI, which are MFI-based pistons, and won't work with CIS. What's the real question here?

I'm taking delivery of a ROW (Japan) 74 2.7 CIS engine with 68,000 kilometers which I plan to rebuild as per your book. I'm lining up S cams and I have a set of webers to use, so I guess the question is; given the low kilometers, the pistons and cylinders should be well in spec, however I was looking to up compression and don't know where to go from here... are the CIS cylinders appropriate for hot-rodding my engine?

Are the Euro 9.8:1 3.0 pistons listed on the Pelican Parts website compatible with CIS or Webers or both?

This would be part # 99-0174-916.

Thanks.

The 3.0 Pistons would be compatible with CIS and Webers. Although, to get max performance out of the Webers, you would want to upgrade to a more agressive cam, which wouldn't be compatible with these pistons.

The CIS 'S' cams would go well with the 911S 2.7 pistons. I have a set of newly reconditioned 911S 1974 cams for sale if you're interested. $495 incl shipping...

i think you mean the MFI version of the 2.7 piston, which has a flatter crown, valve reliefs and the same 8.5 compression. generally used with performance cams and carbs.

No. My 2.7 is long gone. I have a 3.0. I am looking for pricing on 9.8 pistons and also pistons to push the 3.0 displacement to a 3.2 short stroke, both of which would need to work with Webers and S cams.

Any ideas?
