Yea your turbo price is off man. First off the Turbo has been rebuilt! Second, it has not been ran so noone can confirm it has been rebuilt correctly even some reputable shops drop the ball sometimes and in this case the buyer gets the short end og the stick.
Third, and foremost HOW MUCH is the new compressor? I can get one for $50.
Thats a $400 turbo brother , sorry to be the bearer of the bad news.

I can get a Precision BB brand new with all V-band ends for under a $1000.
