That thread is for, "Oh, that's cool. I want to show every one else." You want to know if this product will work for you.

for one it says Remember these are HYPEREUTECTIC and not regular cast pistons. To me that is one deturent. two they only cost 60 bux.....kinda low dont ya think. And inorder for these to work you'll have to bore your block .030 over

The stock piston is HYpereutectic so whats the problem.I bought one of this pistion about 5 month ago on ebay and its currently in my block.They seems to be in great shape when they arrived at my door and when i measures them.

So these are 7.8:1 compression pistons with the same strength treatening (Hypereutectic) as the stock GT pistons. So I guess these are good for a rebuild?... I don't see it as an upgrade at all unless you need a rebuild and need to go 30 over.

Good Call.
I wouldnt mind a set for my rebuild.

fastest: stock compression is 7.8:1

and yes, if you want to use those pistons, you'll need to have the block bored .030 over for everything to jive together. you may also need oversize rings as well, but im not positive.

There is likely nothing wrong with your pistons if they engine is just running rough. A mild hone and new piston rings would likely solve your issues without having to pull the engine and have it taken to a shop for an overbore where they may or may not drop the block and crack it internally so you'll find out later after its reassembled that coolant is filling the combustion chambers but you swear you torqued down the headgasket correctly and you wonder what oh what could the problem be?

Really? I know.

My point was that these are no better than stock pistons. So unless you have a NEED to bore it .030 over, then there is no need to buy these.

Whenyou bore an engine over, You increase displacement, and at the same time increase the compression ratio a smidge. Good luck if they are sealed power. My friend rebuilt his engine with those last year, and 3 out of 4 pistons cracked their ring lands between the two compression rings.

Another reason I say just re-ring what you got and dont change a thing.

actually the increase in compression from an overbore is more of a gain than the increase in displacement which is very small. the exception to this is if you're doing a massive overbore ( more than .030 by quite a bit ) and preferably if you have several more cylinders.:freak:

They're not weaker? That's news to me. I thought they were basically the same as my 2g pistons... which aren't necessarily "weak" but surely not as strong as the 1g turbo pistons.
