Boosted ls/vtec ohh yeah!
Hi everyone, my friend wants me to build his 91 prelude si with the b21a1. My question is does anyone make aftermarket pistons and rods for this engine? I didnt want to custom order anything for it. I was hearing about h23 rods working but I have no idea if that is true. I have not built any of these before so I anyone knows what will work in it or where I can get parts that would be great.

I've personally never heard of any pistons for that engine, but that doesn't mean they're not out there... but I doubt it.

As for not ordering custom pistons, do you really think that's realistic? You're not going to find anything off the shelf for an engine that hasn't been made in 17 years and that not many people modded.
