That looks a lot like a turboneutics T4/T3 turbo. Because i have one on my accord. The turboneutics T4/T3 turbo is good for 450 hp. If you are looking for 650 - 700 hp you need to be running a turboneutics T series. You would have to do some descent modifications to fit one in your engine bay. What type of fuel system are you running? Most importantly are you planning on running a stand alone computer (If you are shooting for those high number I sure hope you are). It could be a T4 in the picture which could produce almost 600 hp but to me it looks like a hybrid. I am just curious it looks really good. I am currently doing the same thing. I blew my first engine when I put my turbo on it. So right now I am running a used engine while I rebuild my old engine with Darton sleeves, Je pistons, Cunningham rods etc. I want an engine that handle close to 20 lbs of boost. Good work though, and keep me updated on how your car progresses and I might be able to help if you have any questions.
