Ring choice is critical if you want to have long engine life. The excellent factory rings have been discontinued for some time now and there is no suitable exact replacement ring available in the aftermarket. Most, if not all "OE replacement" rings are made of some type of cast ring with a sprayed-on or filled "moly" ring facing. The original turbo 2.3 rings were a ductile iron ring set with a plasma moly facing that would often times last 200,000 miles or more...quite a feat in a heavy T-Bird with a small displacement turbocharged motor.

We've been able to find rings that are made from the same material as the original rings and are then gas nitrited for increased longevity. The "catch" if you want to call it that is that they won't work in standard turbo pistons, so in conjunction with CP Pistons, We've come up with a complete piston and ring package that has the excellent rings and high-quality CP pistons.

These rings WILL NOT FIT STOCK/STOCK REPLACEMENT PISTONS from other manufacturers. These are 1.2mm, 1.5mm, and 3mm thick.
