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? |

QUOTE(Dave_Darling @ Feb 19 2025, 06:21 PM)  Note: the 96mm barrels (P&C kits?) that will fit into 1.7L heads (w/o machining) are thinner than those that fit in 1.8 or 2.0 heads. The registers where the cylinders fit in a 1.7L are 100mm, leaving only 2mm thickness for the (cylinder) barrel at the top (where if fits into the head). The registers for 1.8 and 2.0 heads are 105mm, leaving 4.5mm thickness for the (cylinder) barrel. Generally the thicker one is better. --DD Dave I keep hearing this same info regurgitated on the interwebs but Ive never encountered such a set of 96mm cylinders & Im not aware of anyone that actually sells them ? |
