I have a escort turbo bottom end, bored out with 81mm low comp Accralite fordged pistons, i had the bottom end stripped down to check it over,

The specialist is now telling me it could do with new piston rings, ive had a look on burton power and the ring size is different to what the specialist is telling me,

The sizs are 1mm top, 1.15 middle and 2.85 bottom.

Is there anywhere other than Burton that do piston rings or has anyone come accros this before???

Thanks
