A B18C1 can be built all-motor to be better than the B18C5 AND cost less too? Could you explain? I was under the impression that the B18C5 was a superior motor to build up for N/A applications (one example: higher cost to port and polish a B18C1 versus paying extra for a B18C5). Lemme know; I had given up all hope of an affordable all-motor build-up for my gsr.

Maybe I should ask in the engine forum
