    which piston set for rxt rebuild

    hi another question, about to rebuild my rxt after loosing two exhaust valves, ski allready has stage one supercharger wheel, 10psi, riva blow off valve, greenhulk waterbox and resonator bypass, opas block off and reflashed ecu for higher revs,ive ordered supertech valves, was gonna order either r&D or supertech springs and retainers? also looking at different piston kits, who recomends what, alot of what ive read on here recomend the cp pistons, and i know i need to go 0.5 oversized as slight marks to bore, but what compression ration they either do 8.4.1 or 9.5,1, was wondring what peoples opinions are?

    The alloy of the different pistons will determine the skirt clearence. I have Not used CP pistons. But I have installed 2 set of WISCO in a RXT & RXP. Both are Back on the water Running HARD Every weekend......

    the 9.5 pistons will add a lot of low off boost power
    but they will not be pump gas friendly
