I have trolled through the wheel and tire section for quite a while and also used the search function with no luck...I apologize in advance if this has been discussed. I am looking to swap out my current 15" wheels for a 17x8 front and 17x9.5 rear combo. All of the wheels that i have seen have a...

I am in the market for an-intake fuel pump and I've been reading up on some older post form 2008 about the Walbro fuel pump failing after a very short time in some applications. I haven't been able to find any recent posts on the subject and was wondering if Walbro addressed the problem? The...

I am trying to remove the volt booster and can't figure out where the brown wire goes once I remove the volt booster. The volt booster has a plug that attaches to the alternator on the back passenger side. If I remove the volt booster, i won't have anyway to attach the brown wire to the...

The part I am talking about is the red plug that mounts on the passenger side valve cover. I was wondering if this part is necessary? I don"t have the filter on the one port and have nothing connected to the other port. I currently hace a turbonetics racegate with a turbonetics manual boost...

I just went to change the PCV valve and noticed that it had a funny brass thing mounted inline on the hose going to the vacuum block. After some internet research I found that it was a Kirban's PCV check valve. What are the opinion's on this piece? Is it necessary?

Took the car for a ride, noticed high o2 millivolts (880's - 910's) pulled the car over and tried to adjust fuel pressure on the bosch regulator and it wouldn't budge. Changed to an accufab unit thinking that the bosch was bad and same thing, can't adjust the pressure and it the gauge only...

Does anybody have any experiences with the ECM going bad on them. The reason I ask, is that the TurboTweak chip that used to run great now won't build over 5 lbs of boost and another chip that I had that ran strong no throws a rich (mal 45) code. I have replaced the fuel pressure regulator...

I took the gn for a ride the other day and noticed o2 #'s in the high 800's and low 900's. I also have been getting the MAL 45 on the scanmaster. I stopped the car, popped the hood and attempted to lower the fuel pressure. I attached the gauge to the rail and no matter what i did, i couldn't...

Last fall I noticed that the car started acting funny when I would try to build boost. I was normally running around 18 to 20 lbs of boost with no problems. As the fall went on, if i tried to build 15 pounds of boost, the car would surge and build one more pound than back off and drop two...

I posted in another post that I just purchased an 87 gn. The power windows are really slow. I was planning on replacing the motors and thought that I recalled someone selling a window booster that made the windows move at a faster rate. Does anyone know what I'm tlaking about and where I can...

I just purchased an 87 grand national and the boost gauge and tachometer do not work. The dash is the one with the 85 mph speedometer. Anyone have an idea of where I could get a new cluster or anyone that repairs these? Thanks.

I just installed my street chip last night and took it on a run so the ECM could learn the new setup. All I can say is wow!!! The idle is rock solid at 800-825 RPM, throttle response is instantaneous without any hesitation. Interestingly, the car used to stall when you would quickly let out...

As the post states, I am looking to purchase a center console lid with the hinge preferably from a GN. I am new to these cars and don't know if the console from a T-type is the same console as the GN's. I am set up for Paypal.

Does anyone know where to find a power steering rebuild kit for an '87 GN? Also, is the power steering unit unique to the GN's or are they standard buick regal units?
