I do have more questions.. I want to make a ebay turbo and junkyard setup because I dont have 3000 to toss away..I was thinking about a T3 Or T4 can I use the apropriate wastgate to run at 5 psi? and what wastegate should I get that is already set at 4 or 5? And is a T3 Or T4 oil and water cooled? Is there one that is just oil cooled.? Thanks for all the great answers. If there is a easyer to use turbo than the T3 Or T4 let me know your opinions...
