The GN is good

Hey, yeah i'm only like 15 so I just want to talk about the GN and or GNX and don't get all pissed if I'm wrong about something.

I got some figures and some questions so anyone who has this car could help me out.

Yeah, the first thing is that I think the '87 GN/GNX is a nice car is because it's well-built and fast.

GNX: 3.8L V6 Turbo 276 bhp @ 4400 rpm, 360 ft-lb @ 3000 rpm.

GNX: 0-60 in 5.5 seconds, 1/4 mile in 13.43 seconds @ 103 mph.

That's for the GNX, but the GN is a bit slower.

'69 Comaro(COPO 9560) 427 V8 430bhp @ 5200rpm, 450lb-ft @ 4400rpm.

(COPO 9560) 427/430bhp: 0-60 in 5.3 sec, 1/4 mile in 13.16 sec @ 110 mph.

Now that '69 has a huge engine(427 V8) and is only thenths of seconds beating the GNX. GNX only has the little 3.8L V6, but it also has a turbo. Well, i guess what i'm trying to say is that engine size isn't everything.(and the GNX is a sweet car)

One question what would it take to get a GN to about 500 bhp?
:yugosmili :feedback:

My favourite car is an Alfa Romeo Spyder; the classic one from the mid '60s to the mid '90s.

My favourite American car is either the early-mid '60s Lincoln Contintental 4-door convertible or the '71-'73 Buick Riviera "boattail" coupes. Or some other one I haven't thought of yet.

What all do you want to know about the GN

I just wanted to know what would it take to get the GN to 500 hp, and how big is the turbo?

I don't own a GN, but I plan to get one. My dad had a Buick T-type so that's the only one I've got to be in.

Keep the feedback comming! :iceslolan

It doesn't take a whole lot man, Andy can tell you better than anyone though.... someday i'll be able to inform you, hopefully in another year or so...

Keep in mind that the figures on the sixties cars are in SAE gross, not SAE net, and they weren't as efficient at getting power to the wheels. I'd take the GNX any day :)

a GN or a GNX??? there is only 547 GNX's made.

why is are all the HP goals 500 HP? Anyway, do you mean 500 crank or 500 at the wheels

The Goal of 500 seems easier than 700 or 1000, and then there is the money issue. I'm talking about at the wheels.

(and yeah there is only 547 GNX made so I think he means GN)

(i thought it was cool when i just saw a GNX let alone even seeing one for sale, and plus I would think that most people would keep the GNX in some place and not drive it much.)

I'm saying if I could have any turbo Buick, I'd take the GNX. I realize that it's much easier to find T-Types and Grand Nationals.

LOL

The GN was rated by Car and Driver in 86 0-60 in 4.9. The GNX was also tested by C&D and they posted 0-60 in 4.6 on it.

Anyone seen the March 1987 edition of Popular Mechanics? The cover story was a battle between America's fastest cars.........Corvette B2K Callaway, and Buick GNX........anyone whanna guess who won in all tests?? GNX is the best. Fastest production sedan in '87. I'd give anything to own one.............................

I just bought an 87 GN in June of last year with 50K original and it is an awesome vehicle. I'm old enough to remember when it was new in 87, but now, I'm enjoying owning one.

I do all of the work myself and have made a few modifications and now it spins 1st & 2nd gear with the stock turbo. They don't make cars like they used to with full frames and don't have one rattle in it 17 years later.

Some insurance companies also will insure it as a classic if you meet the requirements. I was glad I was able to because it costs peanuts to insure that way.

The GNX i see has the same base engine as my buick regal, a 3.8L V6, which i plan to supercharge (look in regal section, i have some questions), what else could i do to it to increase hp/torque?

anything you want to do to incrase HP will depend on the ammount of boost you can run.

Your block may be the same but the crank and pistions are not.

It's Spelled Camaro!!!!

bring you camaro to Ohio... I will show you how to spell camaro buick style.... :evillol:

I would take the Mustang Boss 429 anyday. My dad had a 70 Mustang Fastback with the 302. I think that any 64'-70' Mustang would be a blast to own and restore.

You deffinatly need to drive a GN then. :evillol:

This may seem like a weird question, but where can I get a factory turbo for the GN? I want to put it on my LeSabre (86), and have decided that putting the whole GN motor in place of the one I have is not cost-effective.
Does the GN have a Manifold Air Pressure or Manifold Air Temp sensor?
Is there a way to regulate the wastegate using the vacumn?
What I really need is a bunch of schematics for the GN...
