how much boost can i run on stock internals?

 

Keep it 8 or under for safety. I don't know offhand of any companies that even make rods for that engine, Crower can do it custom though.

 

Well i have two b20's, and the one that i plan to supercharge is getting a full rebuild, i guess the parts guy can help me out.

Did anyone know the difference with the b20a5 and b20a? what the 5 stands for?

 

If you have one marked only B20A, it's most likely a Japanese market engine... which can be weird, as it could be an Accord or a Prelude B20A. They are very different, and the Accord version (gold valve cover, IIRC) is worth a few bucks to 86-89 Accord owners.

 

Well thats weird, cuz i already bought the b20a out of a junkyard, and the prelude it came out of was beat to crap. It didnt look maintained at all. Not the kind of owner to do a JDM motor. That would be cool though, ill look into that more, maybe call up a dealer.

Thanks alot for your help guys, Kai and everyone is helping alot. I think I've got a handle on what I need to do to this thing to make it work.

I also think I know which superchargers would be ideal, theres a Vortec v-1 I think that might be suitable, and the G60 supercharger for the VW Corrado.

I'm thinking I might do 8-12 psi, (i havent yet ensured that these chargers run these levels) and build the bottom end right to take it, I think the engine builder guy I know can help me there. Also, Ill see how much more fuel Ill need, and redesign the fuel rail appropriatly. Am I missing anything else so far?
