What would cause this? Is this normal? 87GN, just cruising at speed, the retard and knock will climb, then settle back down, but I notice no change in the motor. Engine runs great. Here is link to video. Have a knock guage too, and it shows the same thing when the scanmaster does, so am...

Can anyone post examples of catch-can setups you have done?

We will be in the Friday night open header cruise tonight. I live the sound of the turbo with the plate unbolted from the TH downpipe. The TE44 really sings. Also, in case anyone is interested, we have an appointement on the Dynojet 248 at 9:30 am Saturday morning. I am really curious to see...

Just installed a new scanmaster 2.1 in an 87. With key on, it works. When I start the engine, i see it display 2.1 for a second, then nothing. There is still power there. Any ideas?

Anyone going to the Lane Show this weekend? Lane Automotive Car Show

I will be taking the 87 "GNAT" to the Lane Auotomotive car show this weekend. I am scheduled to get the car on the dyno at 2pm this Friday at the show. How do you all think this will perform? I have the TurboLink DOS version, and plan to record the dyno session. I will post results after the...

Lane Automotive (imagine having a Summit showroom in your back yard) has a yearly car show/cruise (www.laneautomotive.com). This year they had the first open header cruise/contest. We entered our '87 (you can see us in the pictures at the website). When you take the plate off of the TH 3"...

Anyone watch the bullrun reality tv show? Who are you rooting for?

Here's the situation. The bottom of the radiator shroud came loose, allowing it to hit the fan. Bottom half of shroud is now trash, and fan is bent. What vehicle/motor combination could I possibly hope to find a replacement shroud and fan for my 84 hot-air? And better yet, what...

Dad and I plan to take his 87 to the track somtime in the next month during a test and tune to see what it will really do, fine tune the car, and have a little fun. We plan to hit Osceola Dragway near South Bend, Indiana on Friday's test and tune. First, anyone know how many passes I could...

How about this for a cheap cup holder idea? Get one of those $0.99 cup holders that clip to the door, cut off the "hook" part so that you just have the horizontal tab. Remove the center console and flip it over. Remove one of the screws that hold the top piece to the main piece (probably best...

I need to replace the stock fan due to som cracked blades. I have noticed on the past few SUV's I have had (Bravada, and now the new TrailBlazer), they have belt driven fans that are plastic. Anyone know if any of these will fit our GN's? My Bravada was a V6, and my memory tells me it looks...

I created a customizable window sticker for the later GN's a few years ago. I now want to make one for the 84. Anyone have pictures/scans of one I can use for reference? You can block out your vin if you want. If you have an original, a high resolution scan would be greatly appreciated...

Anyone use that new LizardSkin undercoating? I saw it on Musclecar show on spike last week. Stuff looks pretty cool.

I am replacing some interior panels and recoloring some faded panels. Anybody give me a recommendation on right SEM can color number for the 84 GN? (different than 87). Thanks

Anyone go to the Lane Automotive car show this past weekend?http://www.laneautomotive.com My Dad and I were there with his 87 GN.

Dealer says that the the t/v detent cable that goes to the tranny (25532115) is discontinued. Apparently no dealer in the country has one, and according to few links I have seen the aftermarket one doesn't work. Any ideas anyone? :confused:

I have an 84 GN. The exhaust from the cat back is shot, so I am replacing it. I can't afford to do it all at once, so I am asking if the following is possible. I still have the original cat that the previous owner (my brother) accidently dropped a screwdriver in several times. Anyway, I...

Is there a supplier for new inner fender wells? I need to replace both on my 84GN. And I think the fender wells are different for the 84/85 vs 86/87. TIA

Well, I am in the market for replacing all of my filler panels. After years of storage, they are all dry rotted. Thank goodness the body didn't rust out on me! Anyway, I see that I can get aftermarket ABS fillers or fiberglass fillers. I do not intend to go hog wild with getting it show...
