Ok. I currently have an LS and will be doing a rebuild in the next few months. Not sure if Im going VTEC yet or not but eh. I have a set of B16a pistons for when I do this. Will I need any modifications to the rod or piston to get them to fit? Anyone have this setup? thanks guys.

 

I don't have the set up dude, but I know that b16 pistons have the same bore as the LS block (81mm) and they don't have to be machined to fit on LS rods.

If you're going aftermarket rods, then the slugs will have to be machined to fit on them, like every other oem piston.

But with stock rods/pistons you'd be all set
