7.3 Turbo piston rings?

[Ironman03R]

Are the rings different from the N/A 7.3 and the Turbo 7.3?

I know on other engines... the pistons are different, turbo runs lower compression - dished and non turbos run flat top.... and the rings are the same. This is for smaller gaser v6's.

The only difference in the piston is the pin diameter, N/A and turbo IDI's have the same comp. I'm not sure on the rings.

Rings are different.

The top and intermediate rings on a 7.3L IDI are a keystone design.
Top ring is 15 degree second ring is 6 degree oil control ring is rectangular.
