I responded to a turbo request over in the modular forum a while back, try a search and see what you find. I'm not much into the modular kits, I had to do some research then to supply that person with some kit manufactures.
Keep the boost low on pump gas with a good tune and reliability will not be a problem. I had my kit on for a long time and the motor was completely stock. A little to greedy with the boost one day and it blew a headgasket, other than that, no problems.
