I don't know how many people can really piece together their own turbo setup.. I know that I personally wouldn't know where to start unless I did some intensive research. It's a bitch to piece together your own and takes time gettin it all setup without a kit with instructions. I'd say that unless you absolutely know what you're doing, keep goin with a kit. It'll be better to start off with and maybe help you learn for the future turbo setups you choose to run.
