The guy is an asshole. Period. His website says "turbo kits take up to 3 weeks to make". When people bitch that their fuel injectors are taking over a month, he said "READ THE SITE. It says takes 3 weeks or more."
The guy can't run a business, doesn't make himself look good through the posts he makes on forums, and is an idiot. All descrepancies between FMax turbo downpipe location (bolts to sr20det downpipe with a minor flange rotation) and his (doesn't bolt to anything but his proprietary exhaust) is because he's a better R&D guy, and his stuff flows better. And that's why he built an exhaust that NA 240sx owners can't use. That's why he built a manifold/downpipe that you need to buy his exhaust to use, or go through a TON of work to fab up stuff to work like I did. He shot himself in the foot, is barely attracting a market, and is an asshole.
Thumbs down. Until something changes, I'll jock their manifold, but never recommend someone buy from him.
