36lbs with a TA33 work just fine.

I miss the Las Vegas Speedrome... that is what it was before they remodeled and built the state of the art facility in Las Vegas. The Gallinas lived in Las Vegas and Marka owned the fastest stock '84 T-type in the Nation. If there is a location I consider moving to just because of what...

Sounds like you want 300 horses daily... and a bottle. Why haven't you looked into nitrous and a Progressive controller so you do not blow it up? I wouldn't look at the horsepower number... you want TORQUE.

Looks to be a fun project... Non Posi rear end car? unusual as a GN... only a handful of the moonroof cars exist (It was too pricey an option for many) Looks legit to me.

I believe all of the stickers can be repopped now... and if not; surely someone out there in the graphics world could create it for you. I predicted years ago when we had discussions on the subject of cloning these cars in Turbobuick chat that eventually someone out there would see the money...

I used a 75 shot on my '84 GN when it was Hot-Air (prior to a group of current mods); TA-33, Ported intake, ported stock heads, ATR exhaust. I was street racing it at the time in Colorado Springs (Thin air) I beat several of the fast cars of the time period, and I am betting they had a bottle...

Interesting read... Mine is surely one of the most loaded '84 GN's Digital Dash and factory moonroof. It also has the nose badge of the T-type car. 96 Build codes.

I purchased a replacement motor ('87 T) and figured it was easy to convert my '84 GN at that point. White Racing Alternator re-locator Terry Houston Down Pipe 3" ATR Single Shot exhaust Jack Cotton set up a Front Mount Intercooler set up for me. S-10 Manual steering. I had a Spearco at...

Drag radials, 2,800 stall converter, Walbro 340 upgraded fuel pump, and 75 horse nitrous "wet" You should be able to do this on "stock" ecm and chip.

Making a come back? Laughing here... no they are not. They are becoming more rare each passing year - as you continue to drive and risk your investments to grandma's turning out in front of you, or someone T-boning you in an intersection. My '84 GN still has Grand National badging on it -...

Nitrous... upgraded fuel pump... 50lb injectors Translator setup ignition upgrade /'87 2,800 converter, upgraded upper/lower control arms, Nitto drag radials, and a wet shot... start small... 75 horses will be noticeable. expected you have scantool

Hmmm... In 1984 when my car came out nobody called it "Hot-Air"... They called it a Buick Grand National. Some of us had went the routes already... a girdled block, ported/oversize valve heads, ATR exhaust, and a brand new TA-33C turbo. You have to start somewhere... ~smile I even...

Intercooling conversion You can convert a "Hot-Air" car to intercooled... it will require longer piping, adapter to intake (or welding a nipple to the intake), reclocking the turbo, and long pieces of pipe to connect... I suggest relocating the throttle body for "blow thru"... It is far...

Some of those rice cars will murder you We have several here in town running low 11's... and a red hatch that has run 9.90's. You would never see it coming.

nitrous works... You don't need a huge shot to see fast spool. I bet a 60 - 75 horse will make a huge difference.

ATR 3" single shot at idle YouTube - 1984 Buick GN Single Shot 3" exhaust Not exactly quiet... :biggrin:

rule violation... "Going Fast with Class" <--- That is the only rule. I own a '92 LX; supercharged 432 inch Windsor, tko-600, and all the goodies... I have owned several and intend on building a "notch" turbo setup someday. It is hardly for the faint of heart. YouTube - Stroked...

All GN's - Are T-types small correction... to another's post. ...With "Interior" and exterior differences. If you look inside the GN's you will see several differences... dash plaque above the glove box states "Grand National"... Steering wheel horn button (someone correct me on this...

Curious - What is your intent? I did the opposite years ago... cut out the bottom... hollowed out interior... ported and added material to ports to get to Felpro 1200 intake size... welded in plate to bottom. Following this with interest.
