i am looking to get a new turbo for my car. i bought the car and it has a supposedly bored out turbo, but i want to get a totally new setup and get a forward mounted intercooler. does anyone have any suggestions? take into account that all of the internals are ready for a very high grade turbo as the car was destined to be a drag car b4 i got a hold of it. anyone have first hand experience? what should i take into consideration when shooping for a set up? would i be able to use my greddy wastegate and blow off valve?
