pistons for rebuild

[turbodsm87]

my situation in that i am rebuilding a motor and my stock pistons are shot. but the bore of my block is still in toleracne. should i find some more used pistons and slap them in or bore out the motor and spend the money on new pistions. What is the diffrence in size on the wrist bearings of a 8.5:1 piston and the stock 7.8:1 pistons??

Look for a good set of oem 2g pistons on ebay. You will have to pay a little to machine the 1g big rods to fit the 2g piston. Other than that they will fit straight in.

As depend how much you are willing to spend? The difference of prices? And if the used pistons look good enough. Just remember to use NEW rings, break them in and use.

I went with new Stock 1G Pistons & Rods - If Xenia altitudes are much above Sea Level I personally would NOT go with 2G Pistons.

Why wouldnt he want to go with 2g pistons. Because of the compression. Many cars have 2g pistons up here in Colorado with no problems.
