i currently have a turbo, but im building a second motor on the side.i want this engine to at least break 11sec. just wanting to know what people think is good for bottom end? thanks guys.

well you could go , aries , wiesco , etc etc basicly any forged. but you dont have to go forged , a new set of hypertech pistons which arnt forged will easily dip u into the 11 maybe even 10 with the right motor setup plus there not that expensive and there a dame good piston.

thanks mate, do you know what the price is for these?

any forged set will cost about $1100 - 1400, depending on brand and what deal u get.

yep... i sourced around and could get a set of Aries forged pistons for the RB30 for only $800!.. Seriously dude just ring arund and get some prices and your set .. and if your doing up a 2nd motor adapt the rb25DE head ont your rb30 block .. have fun and goodl uck budy .. Some original photos have not been recovered yet.

800? thats good, yeah i think i will tomorrow.if i can get anything for around $1000 ill be happy. thanks for the help boys

Cp have fast become the best piston manufacturer in the world. They are used and recommended by most of the workshops I deal with in australia, and are well priced. Call Qauntum Racing Industries, they are the aust distributor, or Hi octane, who are another reseller. 6BOOST

yes cp are the best in my opinion to

no one has mentioned Ross forgies

you can get wiseco's, 20 oversize, for 1020 trade price not bad bejay hook me up!

It doesnt really matter what brand of forged piston you choose. But, if you are after the best as far as machining tolerances go, CP are the leader by far

I am hearing all this talk of CP pistons, can someone elaborate on what these are please. i am building an rb30 s2 to install into my VS commodore, and would like to hit the 300-350rwkw out of it and i hae never dealt with an rb30 before so i would like some ideas on the best ways to build these motors to get that sought of power
