dwats 75 280

Hello Hybrid Z community, I am a new member, but have been reading on this site for months. I have a '75 280z I am planning a turbo conversion in. I have spent months researching and laying a plan and list of items to buy. I have come across a kit for internally wastegated Garrett t3/t4 hybrid, with intercooler and piping designed to fit in the 280z. My hesitation is that I cannot find any info on this shop, and haven't come across many mentions of it on the site. Does anyone know anything about this shop, their legitimacy, and the quality of their workmanship? Please provide me with any feedback possible. Thanks so much. http://simtecmotorsports.com/S30fmic.htm
