Sorry about you losing your dad buddy. Your GN is absolutely beatiful and with low miles its even better, i had a 87 GN and a 87 white T TYPE and loved them both. Sold the GN because i went through some bad times and totalled the T Type which made me sick for a year because like a idiot i didnt have full coverage insurance and the car was mint with only 24000 miles on the whole car and all stock except a chip and K&N cold air system. Good luck with yours, back when i owned my 2 babys they werent sought out after like today so i didnt really appreciate what i had but they are one hell of a car and head turner.
87 GN here and the powermaster works fine if you maintain clean fluid in it. Most people don’t flush the lines and the rubber diaphragm gets eaten. You also need to depressurize the accumulator ball (“hand grenade” )by pumping the pedal 10-15 if you are going to not drive the car a week or more.
Take your charcoal canister out and move that K&N filter under the AC lines. Just leave the vent line for the canister. It will give you more room. I've owned and raced these since 87 and so much stuff you can do. Eric Marshall at Turbotweak sells the best chips on the market.
Factory alternator is 120 amps it is great. The voltage booster deal for pump is due to voltage drop from wiring. Less than 12 at pump. U need to download MAF Translator instructions. Get a modern chip from Turbo Tweak. My T dropped 13.8 stock 13.2 with chip gutted cat and boost at 19# When BFG Drag Radials came out it went 12.3. Still all stock turbo/injectors/down pipe/intercooler. They make TA series turbos that look stock. Turbo Tweak makes great chips and has a translator called Axis where u can +- timing or fuel. A good torque converter will do wonders. First thing though Replace Timing Chain Set. Has plastic coated gears that cracks and comes off
I would do it up a little bit if i was you as long as you do it tastfully because your not gonna get rid of it for it being your dads so your not giving no disrespect from doing it plus you will enjoy it so much more just by doing a few simple things like you said like front mount intercooler bigger injectors and what ever else you think of.
Powermaster is what the brake system is called. Mine went bad on me soon as i got my 20k dollar worth of work done car back from being restored. I used the monte carlo ss brake booster with the pedal change.
@@blakesmusclecar Yeah not that I would want to wreck it in any condition but having just put 20k into it I was really scared. Light came on but brakes still worked enough to get to a small plaza so I could call a towe truck.
I have a 500hp 600tq car. TE60 turbo, 3inch down pipe, TA headers, pypes 2.5 exhaust, turbotweek chip, razor alcohol injection, t top orginal 74k car, engine rebuild stock still with flat tappet cam. 87 GN does quater mile in 11.5 seconds. Scanmaster G.
@@uptownsamcv Some people go with 3 inch. I'm good with the power I'm making right now. If I was gonna go up in power it would do roller rockers, maybe a different cam, probably run e85 and look into a aftermarket ecu to control it. It does sound bad as far as exhaust goes but the old GM v6s really weren't about exhaust noise like the newer v6 are. My typhoon is loud as hell with the 3 inch exhaust.
@@uptownsamcv The guy who builds grandnationals, Steve V out of Virginia he has years of experience I think he did some tests on different exhausts. I think the biggest upgrade as far as exhaust goes are the TA headers. I'm not 100 percent sure what his recommendations are for higher than 500hp cars. I think once you start using aftermarket internals and different cams bigger may be better. From the buick forums the 2.5 and 3inch flow about the same but you get a deeper sound from the 3inch.
@@blakesmusclecarI REALLY WISH I BOUGHT A GRAND NATIONAL BACK IN THE DAY WHEN THEY WERE A 20 THOUSAND DOLLAR CAR BUT MAYBE I STILL WILL BUY ONE IN THE FUTURE.
@@blakesmusclecarI WILL ALSO SAY BACK IN THE EARLY 90S THE GRAND NATIONAL WAS THE CAR THAT GAVE MY 87 5.0 MUSTANG GT AND MY 93 COBRA PROBLEMS LOL BACK THEN THEY WERE DEFINITELY A FAST CAR.
@@blakesmusclecarGOING BACK 15 YEARS AT LEAST A FRIEND OF MINE BOUGHT A 87 GRAND NATIONAL FOR 20 GRAND WITH UNDER 5 THOUSAND ORIGINAL MILES AND UNFORTUNATELY HE SOLD THE CAR AND LIKE I SAID MY 93 COBRA HAD EXHAUST AND HEADERS AND A COLD AIR SET UP AND GEARS AND I BARELY BEAT HIM WITH MY 93 COBRA AND MY 87 MUSTANG GT ALSO HAD A FEW MODS AND THAT CAR ALSO RACED A GRAND NATIONAL AND IT WAS A GREAT RACE.
Would it hurt the value of the car if you re-painted ? i think a re-paint would be good.. Paint looks good on the video .. good job going to hd video...
GNs were ok but ain't nothing like a GNX with a shift kit for a Muscle Car . Ain't no muscle car touching it ain't too many of them out there but it's the real fucken deal
@@blakesmusclecar lol I was referring to The Ls conversion not comparing the c5 to the turbo regal. why remove what made the turbo regal special in the first place.
Looks fine the way it sits there!!!

Great point! That's probably what killed this one, as my Dad wouldn't ever hardly drive the car for decades.
AWESOME!!! a Grand National and a 96 Impala SS are two cars I would really love to own, they always caught my eye.
Thank you!

Thank you for that information!!! That’s what I was looking for! Appreciate it!
I wouldn't repaint it, I'd have a professional detail and see how that comes out but, looks great the way it is

Love the story. Have one I'm holding onto myself thats fully restored and tuned on alky
Awesome!!!
I love turbo cars after having my grandnational I bought a 92 GMC typhoon
Those were quick!

That’s probably the best way to go

That's badass!

Best thing for it would be a scanmaster. Bob Bailey designed them along with the translator.
Thank you! I will try to find one!!!

Love GNX’s
Don't paint it just do some MT SS 235/60R15 DOT radials on it have some fun with it 160 T stat. Nothing else.. enjoy
Thanks Larry
Too bad people want way way too much for these cars but they are special
Upgrade the whole turbo system
Would make a very nice turbo LS swap.
Noooooo!
Maybe LS swap a standard Buick Regal. I've really been wanting to do a G3 Hemi swap in a Tri 5 Chevy. Just looking for the right car to acquire.
Just buy a C5 better chassis and already has a ls in it
