I ordered a new set of rings, I told them it was for RS Turbo. The rings I got where from Goetze and said 1.3/1.6l CVH. At Burton they have stadard rings for CVH and another standard ones for RS Turbo. What's the difference?

 

when my new pistons turned up they said 1.3/1.6 cvh on the box so i rang up mahle and they said that they were the correct 1s for a turbo but they sell the same 1s for 1.3/1.6

 

Mine are made by Goetze. Burtonpower has standard piston rings for CVH and different standard for RS Turbo. Apperently Burton power sells different rings for RS Turbo. The part no. is different.

 

Originally, the top ring material was different for the turbo rings.

 

.. gudgeon pins and tapered secondary piston rings for improved oil circulation. ... The Series I RS Turbo was produced until 1986, when the Ford RS Turbo ...

Found this at turbocharger.co.uk. The site is down.

 

Interesting. Completely useless though, but I'll have to check on this.

 

So it seems the pistons rings on a RST was different form a normal CVH.

 

Are there other places than Burtonpower that sells them, i like to compare prices you see
