I just sent my deposit yesterday for an SL-R, and am getting ready to buy an engine to ship for fitment. I'm leaning towards the Honda K20Z1 if I can find one with a 6 speed trans with an LSD fitted. It seems that the prices are around $4-5k for a used one with around 20k miles... 200 hp NA and easily 300 with a centrifugal SC or a turbo. Plenty of power to me. I'm psyched about this car, and plan on going up to the shop in a few weeks to select a color for the body panels.
