Well, I'm sad to say this, but it's time to sell my Buick :frown: 1987 Grand National The car is mostly stock with just a few mods. It has been a garaged daily driver almost its whole life. I believe the car was owned by the original owner up until 5 years ago, when someone owned it for...

I need a decent used driver's side front corner light for my 87 GN. A scratch or two or even a crack that's hard to see would be acceptable, just needs to be presentable from a few feet away. I also need at least one presentable center cap because I lost the turbo 6 on one of mine. I...

Just went for a drive and noticed my third brake light wasn't coming on. I pumped the brake pedal a few times with the car off to check for sure, and smoke started coming out of my hood. Smelled kinda like coolant burning, only a little different. Popped the hood and there's brake fluid...

... and my car is slower now... ????? I don't know what to think about this thing anymore... A week ago I took it to the track: Hot and somewhat humid outside, running 15psi of boost. Car feels flat on the top end, and only picked up 16mph from 1/8 to 1/4 Ran 14.4 @ 90 mph with a 1.99...

Stock turbo, Dutt Neck IC, RJC power plate, all fuel system mods, TT chip. No wastegate solenoid, Wastegate is hooked straight from the barb on the compressor housing to the wastegate. I have an aftermarket adjustable wastegate actuator, and whenever I tighten the rod, boost won't go over...

and only picks up 16-17 mph from 1/8 to 1/4... Feels pretty flat up top, so i'm thinking the stock valvesprings are the culprit. Would stock weak valvesprings make it where I can't make more boost? My car has 170k miles on the stock engine, but the heads were "reconditioned" at the...

:D

I posted a big thread about this a while back, but now ive found out some more stuff. When i ease into the boost, I have no problems... however if i get on it pretty good, as the turbo spools, I get some audible knock (pebbles in cylinders sound) and sometimes the scanmaster will register...

When I hit the gas and the turbo starts spooling I get audible knock and then up to 6 degrees of knock retard on the scanmaster, then it tapers off and goes away at WOT. It's an 87 GN, stock motor 91 octane, 12 psi of boost (until i get this figured out) Turbotweak chip for 91 octane Dutt...

Anyone know the specs on the driver's side intercooler bolt? I lost mine, and now it's vibrating and making knocking noises and freaking me out. So I need to go pick one up.

Whenever I hook up direct scan, my car will drive around fine most of the time, but sometimes it bucks and throws a code (something to do with the ignition system). Then it'll run crappy for a while then buck and run fine again :confused: Unplug direct scan cable from the ECM and it's fine...

I've been trying different gaskets on the turbo to header connection because it was leaking (car had a graphite gasket when I got it). I got stuck out on the road and tried a paper header gasket (worked for a couple hundred miles to get me home and such), then it blew out. Then I got the...

I noticed that on my GN at the front corners of the trunk on the wheel wells that it looks like some water has been dripping. (light orange rusty water :eek: ) it seems to be seeping through the seam there below the trunk lid, but outside of the trunk seal. If you can't picture what i'm...

go for a drive and take pictures of course! :tongue: boost > gas mileage :(

If it goes bad I know it can limit boost to 10psi with a stock wastegate actuator, but can it also cause overboosting? Can a custom chip control the wastegate solenoid and raise the boost a lot?
