i think they went out of business. but yeah when they first came out with a turbo kit for the k-series using the gaurdian system( then supposably self tunning piggy back) they made 350+ hp depending on the block and mods. stock a3 running that system made 320-330. a2's made arround 320-350+. man those where fun days at the shop. but their design wasnt casted iron manifold. it was a tubular design slightly longer than a cast iron design.
here's a link to a used one
