SRP, Sportsmans Racing Pistons, I think it is, are forged, and
yes the wrist pins are the same size. I got the wrong ones, I
just ordered by the CR instead of specking out the right pistons
that would of had the right CR for the CC of the head.
CR is determined by cc of the head + cc of the piston crown dish
divided by the cylinder volume so 10cc head+ 5cc dish = 15cc
divided by 150 cylinder cc = 10:1 CR.
for a turbo motor, 8.5 is ideal for higher boost PSI, up to 15, but
fuel is a must, and accurate too.
I would run no more than 10PSI, which will give you 2x the stock HP
approx, so close to 200 HP from a 1.6L engine in a 2500 Pound rig =
tons of fun
