ID This Mahle Piston, please.
 
I started tearing down a 911/07 engine today. It should be a 2.2T. It's not.


I find that I have 80mm P/Cs of the Mahle Biral variety.


I believe this to be an E piston, yes?

Flip it up and look down on the underside of the crown. There should be some cast identifying numbers/letters.

There should be a casting number such as 80wxx or some such. We need that number

It looks like a 2.0 liter E piston from 69. It's a cast piston and would have used the biral cylinder

BURN-BROS 02-10-2013 02:50 PM

Are you sure it's not a 901/07? I think that is a 68L .... It would have the same pistons as the 69E and would be a 2 liter

It's built from parts. It has T cams, 2.0 T heads with casting dates from '67 to '70 and I think it has a CW crankshaft.http://forums.pelicanparts.com/uploa...1360540962.jpg

I have it listed as a 2.0E, 1969
2.0L has a different casting number and its 9.0CR and the 69E is 9.1CR
