im not a fan of something important like a turbo kit and piecing it together with some ebay stuff....even though im a addiment ebayer, the important stuff like a turbo, fuel management, intake,exhaust i try not to cheap out on u know what i mean? good luck and keep us posted....
oh and im not saying nething wrong with piecing together a turbo kit.... but IMHO i would pass on that manifold...try full race
