    I found a place that will do it, and they need this info before they can tell me how much it will cost.

        Stock Bore: 3.800 Inches
        Stock Stroke: 3.400 Inches

        (Both items can be found in the TECH DATABASE)

        I believe stock combuster chamber volume is 64cc. (Found on supersixmotorsports.com)

        The most cost effective way would be to get GTP pistons/rods.. thats what _I_ would do if I ever went with a blower power adder..

        Affordable and Strong.

        GTP's have run 15+ lbs of boost with their internals.. I think thats pretty damn good.

          check out this page. I found it a while ago and figured it could come in handy. Just make sure to follow it down to the right year and application

            Batman what year is your car? On my 96 the rods are 5.75 the shop that is doing your work should be able to measure your stock rods, if they cant do yourself a favor find another shop [img]smile.gif[/img]

              Rumor has it that thrasher has developed forged pistons for the 3.8L and will be offering them soon. Actually, if you call them, they will sell them. It might be cheaper to go that route.
