Wiseco Vs. CP piston Vs. Je piston

[cobrAA]

I can get all 3 for the same price. any particula difference I should be aware?

[gtrjon]

i literally started this exact same thread! http://forums.gtrcanada.com/gt-r-tec...o-pistons.html i went with weisco but most people go with cp!

Funny, I read this from JE'website and it seems like it's the best option for us..

•JE designs are specifically engineered for extreme applications up to, and including, professional competition. In this environment, the higher compression ratios, highest boost or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy.


thanks for the link!

Weiscos are typically porus and they use the much cheeper 4000 series aluminum. Not my first choice.

Doesnt using a forging process eliminate any porosity?

Forged Wiseco's use 2618T-61 alloy

I used cp upgraded pistons and floating pins as my engine builder had very good luck with them and the weight is extremely close when it comes to balancing

I have had great luck with the wisecos in my honda builds. Ex on my b17a used those with crower rods and added 20psi from a gt35r never had an issue but dyno tuned from day one.

Stand behind what you know, I raced moto GP bikes in Australia an they would see 17,000+ RPM for 30 to 50 minutes straight. We always rebuilt our engines with Wiseco pistons and never once had a issue. Are there better options ? sure there are, but I have developed a trust in Wiseco so thats what I run in my GTR. 500+ whp all day.

well.. I went with JE piston. JE have better ring from factory suited for higher pressure like nitrous and turbos. At the end, however, I think the difference is very minimal so I went with the cheaper too.

All about preference. Pick on and install em. You won't make enough power to fail them so don't worry. I chose cp but shoulda went with je

When ordered that way yes they do. But in general nope your wrong.

It is a higher quality then the 4000 series thay use. Standard forged Wiseco's have greater expantion and ring bypass then higher end items. Im not saying they dont work or live at 500whp bla bla. Im saying of the 3 they are not the best option. And definaltly not my first choise. Although none of thoes 3 are my choice.

This is directly from Wiseco
Pro Tru pistons are forged and machined in-house and are designed to make excellent power with a long life and the best value. Dedicated forgings require minimal machining and insure a strong, lightweight piston at minimal cost. Design work is very detailed to insure the latest piston skirt profiles for minimal rock, tight clearances, and long skirt life. Pro Tru pistons INCLUDE a high quality plasma moly ring pack.

All machining is done on the newest CNC equipment, insuring excellent machining at tight tolerances. Most Pro Tru pistons use a 4032 alloy, however big block pistons and certain small blocks designed for nitrous or boost receive the stronger 2618 alloy. Pro Tru pistons are generally made for a budget minded consumer in the domestic automotive market running a Buick, Chevy, Ford, Dodge or Chrysler.


Plus I just specked out new pistons for a customers engine and had to special order the 2000 al.

That is definatly an assumption. But no

Which would you use? Cosworth, HKS? Tomei?
