Well, it's one opf those things where I'm using factory turbos that I rebuild and they are selling these things for not much more than I can buy a used core and rebuild it. Actually they are selling for not much more than some cores. In one of my other projects I am using two 84-85 GN or 85-86 tbird 5 speed turbos (same turbo essentially) and they are selling these new for around $135. But I don't want to be the guinea pig.
Maybe I will try one on my wagon. Don't have any real money into that engine so if something happens I won't be out anything. I'm building a blow through carb setup using a stock 84 3.8 with 86 GN cam & springs, 86-87 headers, 85 GN turbo, 4 bbl carb, no intercooler, but w/ meth/h2o injection. And I bought the engine for $10
