If you dont mind me asking, How much did you pay for the wrecked Z with the turbo engine, then rebuild, and the labor to install (seperatly if you can remember). I'll most likely sell my z and get a turbo, but thought has run through my head from time to time to do a slicktop tt convert. Guess it depends on what it would cost really. One member here did it for 2500 buying wrecked clip, selling old engine and doing all labor themselves.. but i know it would be a bad idea for me to try and do labor myself without much previous experience. So it probally depends on how much I could get a shop to do the swap for.
If your going from NA to turbo w/t28's thats going to be insane.. heck of a differnce and worth any penny im sure.
