/HKS Turbo Kit/
HKS T51R Kai turbo kit is the largest bolt-on turbo kit offered by HKS. The turbo kit comes with HKS T51R Kai turbo, 2.3" tubular stainless manifold, 60mm HKS GT wastegate which supports 1000+ HP, 4" intake pipe, HKS filter, 3.25" downpipe, aluminum crossover intercooler pipe, and misc. hardware. It's a bolt-on kit. This kit allows you to keep the air pump. The wastegate has a pipe that routes the outlet of the wastegate back to the downpipe to reduce the noise when wastegate opens. We have installed this kit on the project car, hence we can give you technical advices on the installation.
