At Modern Performance, we dont list custom bore sizes on our website for our pistons, but we can have custom sizes made. Take for example this customer that originally ordered 10.5:1 pistons with .20 overbore for his 2.4 Stratus motor hes swapping into his 1995-1999 Dodge/Plymouth Neon. He dropped off his block at the machine shop and the machine shop BORED OUT HIS BLOCK BEFORE RECEIVING The pistons for some reason to .40 OVERBORE!
So, we custom ordered JE .40 overbore pistons and we had the skirts coated with their anti wear/friction coating. Here are pics of the beauties before we sent them out!
If you ever need a custom bore size larger than .20 over (we stock standard and .20 over) then call us to discuss. We’d be happy to help you.
