Does anyone know where I can get a JDM Type-R throttle body?

And how much power will it give me if I put it in my 98'GSR?

 

check the classifieds on here, just bolting it up probably won't do much you will need to port match your IM to utilize any gains, check max bore the can overbore your tB to type r spec or larger for like $100 or so dollars
