Does anyone know if Kawasaki 75mm XC Wiseco rings fit the cosworth pistons?
The kit doesn't come with rings

Just for reference i have just measured a brand new Wiseco piston and the ring width gaps are as follows. Top and second ring thicknesses are exactly 1mm.
Oil control ring groove is exactly 2mm.
Measured the piston as you may not have rings to compare sizes and the bottom assembly of three parts would be sketchy to measure accurately.
These are the XG ring format.

Hi speed111
I would contact Cosworth (if it still exists) and ask them what kind of rings to use. Don't take any chances because you might loose a lot of money...and end up with a defective engine if you use the wrong piston rings.

I agree it could be an expensive mistake
and thanks Gus I'll give them a go but a long shot I think
