25lb Turbo "How Much HP Gain?"

[lincpimp]

Pretty much what everyone else said. Are you now buying a non turbo supra? They have a different engine than a turbo supra and will not respond to mods well...

Plus you would have to fab all kinds of plumbing to make a turbo work. I have a feeling the turbo is the cheapest part. And that tubo you liked to is a wet flot bearing type, so it will not last as long as a ball bearing supported turbo. Plus you really want to find one with a 360 deg bearing, not the 270 deg type.
