    I'm running Riva .20 over 8.4:1 with 20 psi boost. Just make sure if you get some, that they are the newest ones with the reliefs cut properly

    Im running Riva .010 with 8.4:1 comp. But as long as your stockers are still good id leave them alone. Stock pistons are really good!! IMO

    yeah I was thinking of running oem with new rings as I have a few spares.
    was looking at getting them flattened on top but don`t know a great deal about what is a good compression for turbo...
    I have a set of 9.5.1 rivas but think that will be to much compression ?

    Would be able to run higher comp with meth injection. You can chose any comp with the CP's, I'm sure it would be the same for the CP's to suit 4-Tek.

    I think I will run oem and get Les to dome them .
    If I was going with new ones I would probably go SDC custom wsm pistons but I have to get rid of these 9.5.1`s to buy a new set !!!

    The WSM ones Les uses are supposed to be very good, im sure he runs lower comp with his turbo kit but he also runs quite high boost if you not going mad on boost then 8.4 will be fine, just make sure your AFRs stay in check with the stock rings, going lean will burn them out.
