hey wats up. i got a b17wit ctr pistons took it to the machine shop they measured it cyl walls are taperde. so they bored it .25 over didnt straighten them. so the bored it .50 over. first is that too much or will it be able to handle it ? second i wanted to use oem pistons but they dont make oem pistons .50 over correct ? so now im looking for .50 pistons over that will fit onto my stock rods i found je but they only have them in 10.5-1 compression n i wanted to be alil high then that any1 have any suggestions ok thnks

 

and also i have a b16 block so i could take the 1.7 crank , rods and use the ctr pistons in the 1.6 block rite? and wich is stronger the 1.7crank or 1.6 ok thnkas

 

any1 opinons suggestions anything

 

i think honda does make a .50 over, not a 100% sure.

 

RSmachines makes pistons in .50 over.

 

ok but is .50 over too much or wat ? thats wat im really worried bout i dont want to be racing it and the cyl wall crack ya know
