At one time there were FM or TRW Hyper slugs for the 2.2 turbo engines. I had a set which failed in very short order and went round and round with the vendor who insisted that I must have detonated the engine.
Mind you under the same conditions the factory cast pistons never failed!
The vendor finally saw the light when a customers bone stock vehicle that they assembled broke. He stopped selling them after that and the company told him to go pound sand when he requested compensation for his customers.
My machinist with a 383 small block Chevy with a small blower?
The hyper pistons he used on dozens of circle track motor did not take well to forced induction. He found this out a month after I told him he was playing with fire. He was not a happy camper considering the motor was in his work truck. Memory is fuzzy but I think he found a skirt or two in the crankcase.
