I guess you live and learn, last year I bought a 86 GN that had rust all along the bottom of the car, it was running pretty good and I was getting a good deal so I bought it. Only after buying the car did I realize how expensive it is to have rusted parts replaced and the car repainted...

Very clean, rust free, doors for grand nationals, regals, & cutlass supremes from 1981 - 1987. These doors were on a car for only 2-3 years, have been stored for the last 20+ years in a heated basement. There is only one very small thumb sized dent on one of them. The weather stripping is fine...

Hello all, I bought a 1986 GN back in September of last year and drove it for a couple of month until the fuel pump died in November. We had such a rough winter in Chicago this year that I let the car sit in the garage for 4 months until today. Finally got a new Walbro fuel pump installed...

Hi Guys, I need a new fuel pump for my 1986 GN. I figured this is a good time to upgrade to a Walbro and hotwire kit. Is Turbo Tweak a good place to buy these items from? They have one listing for the Walbro: TurboTweak - Turbo Buick Custom Chips and Parts I thought there were...

At what RPMs can I expect the boost to kick in? On my '86 GN, the boost doesn't kick in until around 3k, is this normal? This car came with a fuel pressure gauge, it doesn't seem to function normally, it either stays around zero or goes to 100, is there an easy way to measure fuel pressure...
