I was digging through a storage tote and found a set of NPR 96mm pistons and cylinders.
Is there a difference between one that fits a 1.7 vs a 2.0? |

I measured the wrist pin to the piston top for a 90mm piston and it’s 42mm. The 94mm bus piston is at 35.6mm. I assume the 93mm piston would also be 42mm. Interestingly, a Cima/Mahle forged type 1 94mm stroker piston has a pin height of 35.3mm.
The rod length center to center for the 1.7 and 1.8 is 127mm and the 2.0 rod length is 131mm. |
