Description
Ran these in a motor a few years ago, but the motor had head issues, so I threw the stock 1.8 back in the car.
With these motor, domed pistons MUST match the head casting, and I don't have a 121 head anymore.
Ross Pistons, from Ireland Engineering.
Specs on the pistons:
80mm Stroke
135mm Rods
90mm Bore
Compression 9 to 1
They do have mild scuffing on the skirts, if you're interested, I can forward a WHOLE bunch of pics of the pistons.
Price is OBO, plus shipping
