Passed the 60k miles mark in my GNX on the way to work this morning. Picked it up with just shy of 53k miles a few years back and I've been enjoying the smiles per mile factor ever since. No garage queen here, just a subtle beast that's a blast to drive. And with over 60k, it still looks good as...

Door speakers, 1987 Concert Sound system. One speaker is blown so I'm going to replace both front door speakers. I tugged a little on the speaker cover but it doesn't seem to want to pop off, does the entire door panel need to be removed or can I do the swap without pulling the whole door panel...

Title says it all, I need a pair of NOS or really, really good used rear bumper fillers for '87 GN. Please no reproduction plastic or fiberglass fillers, I have tried all of them and they do not fit right. The car is currently in the body shop on hold until we can locate replacements for...

Car is at the body shop now getting some touch up work done. Front and Rear bumper fillers are broken and cracked as expected after 25 years. Purchased NOS Fronts from nos4gm.com (Highway Stars) but still need the rears ASAP. FWIW, I already tried the Kirban fillers (Front & Rear) and they...

My gauges are starting to yellow on the faces and in fact the temp gauge even gets humidity in it every morning. I was wondering if this is still something available through Stewart Warner? Does anyone know if they are still avail, and if so, what are the part numbers?

Just wondering? I spotted a GN yesterday afternoon on Main St in Huntington Beach right near where it meets Beach Blvd and thought it might be someone here. I was driving my 1968 Turquoise/Blue Impala Station Wagon, damn shame i didn't take the GNX out yesterday. It would have been nice to see 2...

Would the 42# 2.4 ohm injectors Mfg'd by Mopar work on a Buick? I have a set I bought for my '86 Dodge omni that I never used and was wondering if I can use them on the Buick? FWIW, the adjustable FPR I bought for the Omni is actually for a Buick, not that it has anything to do with the...

Does anyone sell a kit to replace the factory hoses for the turbo and intercooler? I'm looking for Black preferably since I'd like it to look as stock as possible.

I'm trying to raise my 02 readings at WOT in 3rd from the 760's to around 800-820... would it be better to begin adjusting my fuel pressure up from 43psi at idle, or should I adjust through my Scantool? I have a TT Street chip, running 91 pump and I am getting 2-3 knock retard and normally...

My cruise control seems overly sensitive. Basically, if it detects that I am slowing down it just goes into almost full-throttle to speed back up. If that isn't annoying enough, the burst of speed from the acceleration is WAY TOO MUCH 100% of the time, which means the car then begins to coast...

In the Turbo Tweak instructions, it says's the following regarding MAF: "4. The chip will work fine with either a stock MAF, or a Translator LT1/LS1 MAF setup. For cars with a stock type MAF, it must have at least one screen in it." My car has a stock MAF, but where would the screen be? Is...

just put in a GN1Performance CAI this evening and on the initial start-up the car is running like crap. Super rich exhaust from the tailpipes and it barely wants to idle. O2 reading at idle on Scanmaster is less than 100 which seems odd. When I rev the motor it tends to stumble a little first...

Just wondering where the limit is? Right now I'm at 43psi @ idle with the hose off as suggested. However, with this setting I am starting to run lean with 17lbs of boost in 3rd at WOT. I'd like to be able to safely run 18-20psi boost on pump gas, but what is the limit of static pressure...

I have a Buick Accufab adjustable FPR that I have run on my GLHS for about 3 years. I recently removed it from the GLHS to put it on my GNX. When I installed it on the GNX this morning and fired it up, the regulator sprayed fuel from the seal around the middle of the reg. The reg has safety Torx...

I think I might be missing some detail? I've got my TPS set to .42 at idle, but it runs at 4.14 at WOT. How are you supposed to get the WOT adjustment to 4.6-4.9 without changing the idle adjustment?

Does anyone know what the approximate Fuel Pressure at idle with the hose removed is when running a stock FPR and stock Fuel Pump hot-wired? The Scammaster recommends starting tuning at 43psi with the hose disconnected at idle, but is the stock FPR even close to that range? What about the...

How long will it take on average to install a Hot Wire Kit for the fuel pump?

The power antenna on my GNX does not go up. When I try to pull it up manually, it gets about 2" up and then the motor kicks in and pulls it back down again. Even with the key turned on and the radio on it's the same thing. I guess it's obvious that the cable isn't broken since the antenna...

I just picked up an ’87 GNX and want to do some light mods, mainly exhaust and ECU program. What recommendations do you have? Can the Cat Conv. be removed without throwing any Check Engine Light, or would that have to be programmed through the chip? I really don’t want to get crazy on this, just...
