I'm rebuilding my b18b block for ls/vtec. I have some SRM forged rods w/ARP rod bolts in my basement. I was thinking of buying some CTR pistons to raise compression. I need to know if the rods and pistons are compatible? I didn't know if they'd fit together without any machining.

Any suggestions? Looking to find a decent priced set of high comp pistons.

They won't work together w/o some modifications. Aftermarket pistons use a floating wrist pin, where stock is pressed in.

 

So, then it's a lot easier if I get aftermarket pistons to use with my rods? Then I won't have to mod my rods from what I'm getting?

 

if the rods are made for oem application then your effin set..oh and find out the rod length.. any rods but ls rods wont work... to long

 

You can tell by looking at the conrod's small-end. If the small-end is bushed with something like a brass bushing, then it's a full-floating wrist pin design and you can't use an OEM Honda interference-fit wrist pin & piston with it without machining the piston for a wire lock.
