Thread: CP Sr20VE 12:5:1 Pistons in a SR16VE =?

Hi what is the cr when u use CP sr20ve 12:5:1 Pistons in a sr16ve is it the same as what u will get using them in sr20ve
Thanks jeff

12.5 in an sr20 will be just over 10:1 in an sr16

i think it would be the same CR.

Using the pistons in a given block will make no difference, but if you use the 86x86 piston it wil yield less cr when using it with the much lower stroke of the sr16 crank...

^+1. Throw a sr20 crank in there. Just remember if your using 16ve styled piston to notch the pistons for the oil squirters.

Stratton.

This for a racing engine must be a 1600 cc how can i get 12:5:1 in the sr16ve

Have cp make you a 12.5:1 piston for a sr16

Stratton - Post a picture of notched 16ve pistons. I want to see where you put them exactly and how you did it.

what info will i have to give CP to have these pistons made

A little off topic lads but do any of you have an idea what CR standard sr16ve pistons would yeild in a n1 engine(head skimmed from factory)?

Might be an idea for enoehttemi to skim his head instead of new pistons?
