I have an 01 LB7 with 100k miles on it, I am looking to do an inexpensive as possible (yeah I know it always starts like this) turbo upgrade!! Is a "cheetah turbo" an option?? Just seems to be more afordable upgrade, no install kit. Or should I be looking into something different? I have anothe LB7 with about 50k on it that I plan to do studs and gaskets on if I need to. Any suggestions or input would be appriecated.
