SR20DET forged Wiseco Pistons

8:1 compression
Brand New

what is stock bore for sr20?

 

86mm is stock. most people go 86.5mm bore with a rebuild but.....
they will work

 

i could swear stock is 8.8 to 1

 

if your talking about compression stock is 8.5:1
most companies offer 8.5:1 and 9.0:1 but they make up to 11:1 iirc

 

I wouldnt buy a set of pistons and just throw them on my motor. You have to take it to a machine shop so then can assure that the bore of the block and the piston size are the same. I had a block that the machinist would not touch until he had the pistons in his hand. Regardless of what size they are they will work as long as things are done the right way.

 

i'am interested on the pistons ,but i need to know 4 sure the compression
on the box whats the part number?

 

Wiseco makes an 8.8cr and an 11.0cr. The 8.8 is perfect for turbo. You'll have to have your block bored for these pistons. I have the same ones except 86.5mm and I love them.

 

thanx epstein.
