I want to convert my car into a sibgle turbo, its a 3000gt sl coupe 3000gt my headers are bad and am looking to buy headers my ? Is would the turboheaders fit my car even tho it has no turbo yet? And would it work with the manifold?

Single turbo would be harder than twin... To convert to twin you need turbo headers, turbos, intercooler, maf from a turbo, and ecu from turbo... Single turbo would require a 99 ecu and a whole lot of knowledge about programming such... Ive got the headers, ecu, and maf you would need sitting around. Im waiting till March to pull the stock turbos and intercooler... Ive got a huge build going on. :-)
