So you had 85 GN , that was one with turbo in back and no intercooler . If memory good the 86 was with intercooler in front of fan /pulleys and that one had ceramic intake blade , 14-15lb too .

I Had an 85 GN I sold it about a year or so ago. I looked at my insurance Bill and saw 3 cars too many so had to make a few sacrifices.

You are correct the 84-85 both had the turbo on top of the motor passenger side and no intercooler. I replaced my turbo with only 60,000 miles on it for the 86 model that had a smaller exhaust housing. In doing so I had to clock the 86 turbo 40% around to make it fit the proper orientation of the 85'pipes. The GN was a cool car I always wanted but a pain to work on very innovative for its time in making power but a true knuckle buster. I sold that and 78 chevy straight six 3 on the tree I restored and a 91 3.1L Lumina that I couldn't kill no matter what I did to it.

doing the turbo add to the tahoe is a fairytale at this point. I have little intrest in messing with the truck. Other than some small ecomods to improve mpg's the Tahoe has almost 204,000 miles and its all stock just general maintenence since I owned it. besides I just custom bent the exhaust for that truck and fully welded it a month ago.

The reason I am here is to hear great feedback that you all have when I have one of my oddball ideas. Most peopel tell me I am nuts you guys encourage and refine the idea to be more of a reality. I have a few projects in the way of my goal of an electric build. I need to learn first hand about all that I am reading here, But before any of that can happen I have to swap a tranny for a friends car, tile a few bathrooms, and finish converting my drag car from methanol back to gas this winter. I hope to be working on something this comming spring maybe pickup a frame and build a forklift powered 32 ford or maybe even a cobra that would be something. untill then I am going to keep my ideas quiet I need to reach the level of confidence and am in more of a position to act rather than talk.
