so whats the deal ,I been doing research on these pistons they say to be for a low budged setup they are cheap and they dont handle much hp like pass 500 whp.
is it really that they dont really expand like cp's je ,arias ,wiseco bc of the silicone ammount
any info in these pistons would be great

thanks

 

What else can be said that isn't in the archives? The pistons haven't changed, nor has the general opinion on them - they are budget-only, unless you get a perfect tune when shooting for high-hp.
