I'm getting a type R oil pump with the engine, u think that will generate enough oil pressure?? Also do i have to get just the crank balanced alone, or do i need to bring in the rods and pistons too to get balanced? How much does balancing usually cost? i have 1400 bux that i can spend right now on the engine, i just though balancing was a good idea. I also have money for sleeeving coming later on, this will be my first engine build so i am going to take my time.
