gs to gsx

i would just like to know how hard would it be to turn a 95 gs into a 98 gsx and also about how much would it cost

Did you read the rules.
First, Read the FAQ
Second, use the search
Third, add your year and model into your sig

It will cost well over 7 grand

probably cost $2000+ just to get it to look like the 98 body style. headlights, foglights, front/rear bumpers, side skirts, wheels, reverse lights. paint prep install....

you are better off selling your car, and buying a GSX if thats what you want because that would be cheaper.
