What brand of pistons are people having the best luck with? Looks like you can get a set of spi pistons for about the price of 1 oem.

stock
I saw where spi claimed their hyperdryve pistons are suppose to maintain their tensil strength at a 50% higher heat than cast. I figured stock was going to be the answer.
STOCK!!!!!!!
Here is a view from the top.

Wiseco all the way. I've been running them for 4 years no problems 8-25psi. I've seen way to many motors taken out from blowing the casters.

Forged pistons are stronger by far than a stocker (cast) piston. The problem with the forged piston is they are more sensitive to combustion chamber and or engine temp. because they have twice the expansion rate of a cast piston. If for some reason your AFRs are high the forged piston can grow enough to Squeek. That does not mean the cast piston will not do the same thing, It just means it will take a few more degrees before it happens. If you measure a cast and forged piston you will notice the forged piston is built smaller (more clearance) than the cast so they tend to rock in the bore more. The pics are obvious detonation with possible overheating, a cast piston will break where the forged will take the deto. There are of course many variables but you get the idea... forged will bend.....cast break.

Stockers are good and cheap, Forged are the best and expensive. You can run more boost reliably then cast.
Well I already put some stockers back in. I hope I don't do this again, but if I do maybe I will try some wiseco's.
