i was wondering if anyone used these pistons and how they worked out as opposed to cp pistons i'm debating between the both of them for a 600+ whp build and just wondering if anyone else had any problems with either of them

 

They work fine. Wiseco makes them for ENDYN

 

Like he stated above, they are great pistons and you can't go wrong. I myself can't decide between. CP, Wiseco, JE oR Endyn(wiseco). I hear that some people have had issues with CP and the PWC and the reliefs on lower bores being to thin. I think since CP has resolved any possible issues with their reliefs.

 

wiseco pistons ftw! ive used them in every toy ive had, dirtbikes, fourwheelers and ive been runnin them on my ls/vtec for about 6 months now
