You are on TB.com which is a good sign. The first thing you need to do, IF you get the car, is read as much info and threads that you can on this site. I am on my third turbo regal and I owned my first 2 back in the early 90's and I can tell you I was lost trying to figure out those cars back in the day. The GN is not your typical big block chevy with points and a carb...you need the knowledge to get these cars running good and a fat checkbook or 3 credit cards.
My point is most everyone on this site that has owned these cars for any period of time will put their 2 cents in to help you out. Dont spend your money unwisely, do your homework. That being said heres my 2 cents: Take all the money you would use on that GNX dash and get you a scanmaster and a Turbotweak chip, and put the rest aside for a rainy day. Those rainy days include: broken trannys, bad MAF, etc... Read what combos work and which ones dont and you will be ahead in the game with a few more $$ in your pocket than I was when I bought my first GN.
