Bad things about a rb26,your hearing stuff from the wrong people my friend.rb26 is up with the jz,bullet proof.Givin' an sr20 is a badass little motor.But give me rb anyday.More work to install in a 240/silvia but worth it.But back to Donny's question these guys could point you in the direction with your plans.
