    I would go lower compression pistons. Those Todas are very nice pistons, but not great for boost.

    what headgasket are you using? 1 layer? 2 or 3 layer. I have a new felpro 3 layer if you want it. Dont for get that Toda sells thicker headgaskets for people who want to lower comp. i'll sell my Felpro 3 layer for 45 shipped

    dude if you are are trying to sell a headgasket atleast tell him what thickness it is. Three layer tells him nothing.

    Bottom line is if you want to keep your pistons then you will need a thicker headgasket.

    you know.......if i new i would definitly have told him. why do think I asked him what layer headgasket he has? Unless he gets something aftermarket like toda,cometic, etc. the felpro 3 layer is the thickest. correct me if i'm wrong

    i'm guessing you dont know what HG you have on now since you havent torn the motor apart.:huh: If it was me i would tear the head and see what i have. If its a 1 layer then you good. That way you can find the thickest. The only place i know that offers thicker headgasket that state the compression is TODA. but then again i know there more companies.
