i just got a 91 prelude, and it has a knock in the crank shaft, so i am rebuilding it. i was wondering since im tearing it all down what upgrades i should buy when putting it back together. i forgot to mention that its a b21 engine.

if u are goin naturally aspirated get some high compression pistons, port the heads and thatd be pretty nasty set up man

 

not sure what to make of a knock in the crank....maybe bad bearings or something....

anyway, you wont find many parts available for that engine, and i also doubt you will see much performance out of it if you do spend a lot of money on it.....you could get some custom pistons made to bump the compression....thats about it...
