Grandfather's '87 GN

Got it buffed today. Still got treesap in it because he didn't realize how bad it was so he didn't have his stuff for that with him. It looks so much better, just needs the bumper fillers and hood emblem put on
Man, she came out beautiful!!!

It's been a LONG time. Car's still around, and broke again lol. Vapor canister is clogged, fuel PSI regulator is still bad, and I still haven't done the fillers. And the alternator crapped out. I got mad and parked it.

So, today I ordered the regulator and canister, and when it comes time to work on it I'll go get an alternator. A high school buddy, and a fellow GN owner, does paint for a living and he said he'll hook me up on the fillers.

Now, in the summer, I roast thanks to the T-tops, and Pap forbids removing them due to the notoriously bad sealing issues. I see the shades are available, but what's the right color? Is it 1598 or 1589?

Also, even looking like this it gets loads of attention and people asking if its' for sale. Answer is still no!

It's funny, looking at the picture you'd think it has 139,000 miles, not 39,000

Wow great read! Welcome to turbo Buick.com. Lots of great info here. I’m local to you. Maybe I’ll see you at Hines. My favorite cruise! If I’m not mistaking my TTA came from Red Holmes. Not 100% sure, I have the paperwork but memory is slipping.

There's a good chance of it, but I might not be in the National this year (I had it at Telegraph last summer, it was pretty fun!)
I'd rather be in this, if I'm honest. I'll daily the GN and take this to cruises.

I like that better too! I don’t take my GN to many cruises. There’s always plenty of the around to look at.

Okay, this is perplexing, but hell, I'll take it!
Got it fired up recently. Alternator is charging it fine, and the canister doesn't seem to be affecting it. I'll take it! (I'm still keeping the new ones as spares)

HOWEVER, it whistles bad under full throttle. I'm trying to get Pap to drive it so he can diagnose it for me so I can fix that.

Here's a picture of my buddy's '87. It was rebuilt by his father, who passed away in 2005 and left it to him. He'll be painting the bumper fillers for me. I didn't know these came with manual windows. He's got it torn apart in the garage at the moment. The trans (apparently a Turbo 400 with a 4th gear added. Not a 200R4) has been nothing but issues since his dad built it, and the wiring's a mess. The car was a victim of an insurance scam fire, and it was his dad's dream car. He's looking to hurt some Hellcat feelings this summer.

Well, it's been two years. Time for an update.

First and foremost: Pappaw has passed on. March 14th 2022. He was 70 and this family is worse off without him.

Onto the GN. It's not mine, but it is staying in the family, as it's going to my aunt.

So what happened to it the last 2 years? Nothing, really. I figured out (but haven't fixed) the whistle. It's the hose from the turbo to the intercooler. I ordered the highway stars kit and that hose was too short. Other two were fine. Also, the Powermaster finally gave up. My uncle and I tossed in the spare but never got around to bleeding the brakes. Hopefully doing that soon, and I ordered another hose today.

Here's a couple more pictures of it from back in the day. Probably 1991? I honestly don't know, there was no date on the photos.

And from when it came home from storage in either 2009 or 2010. And from a month or so ago when I washed it. Reminder that I do have new fillers in the trunk.

What's up with the trunk lock surround?

The originals didn't have one, just a blacked out lock cylinder.

It's just some stick on that says Limited Edition. I don't know if my grandfather put it on, or if the dealership did to try and make it look more special.

It looks like they are on all of the exterior lock cylinders, I'm betting for scratch protection!
ENJOY!!!
The ones on the doors say BUICK. He had similar ones on his 83 Z28 (this car was bad ass. Decided, even after upgrades, that the 305/700R4 was just too slow and put a 383 and manual valve body TH350 in it. Sadly, it burned to the ground one day and that's why we have the Foxbody. He loved this car though. Damn mice/rats

(if you take issue with the plate and flag, please remember it was the 1980s and he was from Kentucky- it was never meant with ill intent.)
You can actually see the hood scoop in one picture that probably contributed to the wiring getting eaten. It was from a 1979-198? Mustang Cobra or GT. He of course had to cut the hood and insulation for it and that may have given them another entry point.

As for the Buick, it put up one *hell* of a fight today. Tried to bleed the brakes, rear left bleeder broke. Spent about 2 hours replacing that cylinder (because for whatever reason the slot on the backing plate wasn't big enough and then the retainer clip design is straight from hell) only to have the other rear cylinder throw the piston.

What makes that funny, it's a line from a movie

No, not taking issue with it. Just wondered, that's all.
I didn't mean to imply you were. I was just aware that the confederate flag stirs up a lot of mixed feelings so I wanted to put that disclaimer out in general towards everybody since they were visible on that Camaro
:)
