I have one complete twin turbo setup and one almost complete setup, both for big block Chevy, it comes with one set of exhaust manifolds, one set of IHI turbos (size is undetermined right now but will have soon,they are big), two sets of Kinsler mechanical fuel injection stacks with custom plenums, another set of turbo housings, oil cooler and a bunch of misc parts for the setup. I can get more pics upon if you're interested, email me or message for pic requests or more details, price is negotiable.. Thanks for looking
