so i bought these pistons used. he said they are Wiseco pistons, several times....but... i helped one of my buddies assmemble his motor about a week ago (at the same time bought those) and he had some Endyn RollerWave pistons, low compression. and they looked just the same as these (his were 84mm) with the rolled edges and 'brushed' lookin tops (i cleaned these up)... but i have cant compare them directly cuz its in the car already and he didnt take pics...

now a couple months back i helped another friend with putting his motor in his car. his motor had Wiseco 9:1's in it. now i only remember seeing them quickly, but i sware there was a part number etched into the top of them, and they had a CNC machine finish to them not a hand finish... but i dont remember what the valve relieves looked like...but most of the pics i found on here have 4...the ones above dont have that...

are there two different kinds of Wiseco pistons? or are the RW ones made speical for Endyn?

so...can anyone positively identify them?

 

endyne rollerwaves are just wiseco pistons which endyne modifies, they use the wiseco's as cores so they are essentially the same thing

 

i know that RW are made buy Wiseco and are 'finished' by Endyn....but i have seen both Wiesco's and RW and they are not the same...


9:1 Wiseco...


agian...

 

well...**** in lookin at those, they are both different too...

 

i think those are the rollerwaves, they are the only ones i've seen than have the valve relief as one large one not 2 seperate ones

 

I believe those are Endyne pistons

I bought my car with those pistons in it and they were listed as Endyne's

 

yup endyn's... ive had two sets of them.

A lot of good information on the website about these pistons...

 

**** they look the same to me there...


so i guess they are RW's then....unless Wiseco sold the same pistons to the public that they sell to Endyn...?

They are "made" by Wiseco, but engineered by Endyn.

 

yeah....thought we covered that?

They are not essentially the same thing. Endyn machines them differently to in theory make more power. Hence, the higher price.

 

i am saying they are the exact same material, and i said the wiseco's were just cores that they modified...
