64 turbo, piston questions...for replacement

Ok, the quest for the right parts begins..

Cylinders to be bored to .020 over.

Need pistons..

Clark's? If Clark's which ones. leaning toward the premium cast or 'hitech'.

Which rings should I use? and which 'hone' for which ring set?

That's enough for now. Any suggestions appreciated.

Forged pistons are the best choice for a turbo but if you have to go cast I would go with the hitech over premium cast.

I used new cast pistons in my 180 turbo.

Six years later it's still running great!

I second the use of forged in a turbo.

If you plan to drive it hard then spend the money for forged.

I installed NOS Pistons and cylinders, and I seriously doubt that I will wear them out in my lifetime. If it was good enough for the cars when new, they should still work just as well today. How many Spyder"s & Corsa's are still running their original pistons today??? If you are building an engine for racing or "performance", then that is a whole new ballgame.

The Hi-tech pistons work just fine, get the Hastings Moly rings and get the smoothest hone you can get the machine shop to do. I use a 380 hone for the Moly rings. No chrome rings and no cast iron rings.
