I'm looking to turbocharge my stock B18C1 GSR Engine. For now, I want to run a turbo kit on a stock engine and sometime in the future I want to look into doing the internals for more power potential. I want to either get a kit thats tried and tested and has the potential to provide more power without swapping all the turbo parts OR put a kit together with parts that I source. My bolt-on kit goal is: 300 HP with front mount on stock engine, injectors and 255 fuel pump. My future potential goal is: 400-450 HP with front mount, fuel management and internal work. I was looking into the XS Engineering Kit, Greddy Kit or Turbonetics Kit as a start. What do you guys think? Is it doable? Any advice / experience would be appreciated. Thanks guys. Sorry I forgot to mention: I will be getting a aftermarket clutch / flywheel setup (probably ACT, Clutchmaster or SPEC) for the added HP. I will be running 93 Octane, thats the best I can get locally here in NY. Would prefer something that will spool at around 3500 give or take a couple of hundred RPM.
