Best boost pistons for 5.3 turbo build

Probably going go with the Wiseco JY pistons but want to know if its worth the extra $$ to go full custom set?

LILHEMI

not sure if wiseco JY pistons are built for serious power. someone else chime in.

Best piston for what? Need more input. Projected power/rpm?

The "best" piston would be a custom unit setup for your specific application by any of the large race piston manufacturers.

Stock pistons have been over 1000hp so I'm sure the ones ur looking at will be fine I'm about to use the same jy piston on my 5.3 build

Call up weisco and ask what the "JY dog" pistons are rated to HP wise. I've heard from 600-1200 FW hp from forum members and have still yet to hear a definite answer. Most of the names I trust tell me they are hype and no stronger than a 2005+ LS piston.

Best option IMO would be to bore it to a 5.7. (3.9x) and buy a piston known to handle the power you want. Diamond, JE, etc....

DemonicZ

No, I'll just buy a custom set or keep the stock

I don't think you can go 3.9x on that block since its the aluminum block.

I think he will be ok with just a set of the JY pistons from Wiseco.

Im using these http://www.briantooleyracing.com/wis...-k474m965.html
at 950whp soon to be 1200.

Get some thick deck heads for it.

DemonicZ

What heads do you recommend?

I've been talking with Martin @Tickperformance a lot about this since I want to build it right the first time. I also have a friend building a 1400hp turbo 408, but that is another monster entirely. haha
Thanks for the help.

DemonicZ,

You're in reno.. Go talk with Bill over at BME(Bill Miller Engineering) in Carson. He builds pistons for race duty vehicles, like Top Fuel and others, as well as street duty and everything in between.. Everything's done in house there for a great price, too.

LILHEMI

holy **** im in reno too. lol didnt even notice. ive heard of BME but dont know anyone that does business there. may have to go talk to him.

DemonicZ

Thanks man I'm just getting started in the LSX world.

DemonicZ

What do you have? I drive a red 98 Z with gunmetal wheels, black berger panel, annoyingly loud exhaust haha.
