Could you please elaborate what is so trick about this pistons and does it comes with rings and pins? Thanks.

Sorry for the late reply yes the pistons come with pins and rings

For best power the pistons will come up above deck to best control piston squish

Wt. of piston #1 is 290.22 lock = 1.47 pin = 75.83 ring 21.93


Top ring is 1mm 2nd is 1.2mm oil is 2.8mm

If you can find some better ones for this price let me know

Do you have the specification sheet? What is the comp height? bore is 82mm, also what is the dome volume?

Yes 82 mm bore it has all the paper work (spec sheet)

What is the comp height? Bore is 82mm, also what is the dome volume?

Why do want to know this?

1) to know how much you can machine the block deck... 2) to properly calculate compression ratio (what if buyer uses thinner head gasket... and/or cuts the head to reduce chamber volume... how will he know the new compression ratio if he doesn't have these specifications

I see all that information is on the spec sheet that will come with the pistons it will also have

Depth from timing edge, valve angle, pocket diameter

Would these be good for a small t3 turbo? My tuner says the turbo will max out at 350-375. I am running hks 8.5 lift 256/264 cams with stock valves. will my head work with these? and are they 20mm wrist pins?

I don't think so get some GZ pistons you would be set (oh GZ pistons are the stock super charged pistons)

Take the short block to the machine shop explain to him what you want give him the piston pn's so he can order them for you
