If you are talking about Turbocharging a NA Supra, i dont htink u can use the factory turbos. The NA engine (2JZGE) has different internals and mounts than the Turbo Engine (2JZGTE). They sell a turbo kit that will fit a NA supra, which will bring it up to supra tt power, stock tt power. I think. Also , u can do an engine transplant, which is pretty costly, but check www.powerhouseracing.com for the specifics on that.
