Yeah I had a ear to ear grin with my rev per 98 kit ,until the nikasil started peeling off. Wasn't the pistons it was the nikasil.
Go to the other forum and look it up , never ever trust them again.

 

Justgot to cross my fingers I geuss

 

Just a quick note boys, it is the sulfur content found some gasoline grades that causes the nikasil to break down. By all means use fuels with as little as possible sulfur content to provide longitivity.

 

Got 50,000 miles on a GMR 98 in Rev Perf cylinders, still running strong .

 

thanks guys for the heads up thought all news would have been bad with this 98" kit
