I have a 98 GS-R. Im still considering about turbo charging it. I want to do the Greddy turbo kit w/ Greddy intercooler. If i do this kit do i have to do any internels, or can the stock motor support this turbo kit. I plan on changing my clutch and flywheel when i blow it up as well. I hear you should do internels but greddy claims this kit works with the stock motor. Any help will be appreciated. Thanks!
