I had a1985 G.N. I done many things to mine,test pipe,Stage 3 chip bigger turbo , 2 Flowmaster ,but one thing that seperated mine from other was the exhaust,kind-of like Mustang exhaust,2 Chrome pipes going to the rear bumper ! Test Pipe,done away with converter
I just ran into your channel...subscribed and as you for details on the build, right after I commented found this video. Great job man! It took me almost six years to finish mine from the frame off, but thanks to GOD it is done and better than new. IMOP.
bro this grand national so hard, my dream car fr fr🙏
I told you last time that this is the best GN I ever seen and it's fast as balls, great job.
Thank you man! I’ll be out testing it this weekend… maybe I’ll get a Dragy Vid up.
Super nice car. well done with everything :)
I almost got those rims but I chose the XXR 521 in all black. Looks sharp!
What lug pattern did you go with?
Perfect!! Don't change a single thing
Thanks man… that’s the plan for now. I have a TA motor and a 4L80 swap planned for the future but that’s about it.
New hood felt with the original Buick turbo V6 logo would be a nice 👍🏻 needed finishing touch! Awesome GN! I’m hunting mine
Hi! Yes I had the original hood insulation on there, but after blowing a charge pipe off it damaged the insulation, but besides that, the insulation sags and rubs on my piping due to the Champion race intake being higher, and also rubs on the AC dryer…..it just made a dusty mess all over the place all the time. I may do a black aluminum hood liner eventually, I’m just afraid it will rattle.
The hood skin is a nice piece. I have one on mine and it doesn’t rattle a bit
Beautiful car!! I wouldn’t expect anything less!!
Thank you!
Your car is awesome. It's at the top of as far as a street car. You have the right combination that you can enjoy on the track and the road. Lots of luck with the TC . Enjoy and I'll be on the lookout for more content.
Thank you man! Since this video was done, I’ve swapped converters about 3 times and had about 3 different 2004Rs transmissions in it. Currently, it has a fresh Janis stg 3 full billet 2004R in it and a Circle D billet single disk converter. I’ll be 60-130 Dragy testing it in the next couple of weeks to see if it slowed down over the PTC 9.5” non lock converter. I’ll post the Dragy video and an update on the car. Thanks for watching my stuff!
Dream car!!!
Thanks for sharing bro
Thanks for watching my video!
That's the best looking GN I ever seen on TH-cam by far nothing even comes close to it and it's fast as hell on top of it, great job buddy.
Wow! Thanks for the great compliment!!
Nice and simple🎉
That cool good looking car.
Thank you man!
Such a great looking car with a stout build. Can't wait to see what it puts down.
Thanks bro! Dyno vid is canned and edited. Probably drop it on Friday. It’s got “bonus” footage at the end too. 😎
Man what a beautiful car
Thanks Randy! If you aren’t already sub’d, please do. I have more Buick content coming!
You should put a roll bar or cage in it I love the look with one.
Haha.. no roll bar for me. This is a street cruiser, roll bars suck in street cars.
Awesome car. I'm currently building a TA performance aluminum v6 block w/ se heads rjc intercooler 5inch downpipe w/4 inch exhaust. 72/70 precision turbo. Full Throttle speed is building the motor. Hoping low 9s or high 8s
Sounds like a killer build! I have a new TA block sitting in my closet, planning my long term build on that. Bryant billet crank, Oliver billet rods, Diamond gas ported pistons and using my current TA top end. Not sure if I’m doing a 6870 or one of the new Xona rotor 71mm V bands. Still in the planning stages. Need to save up more moolah….
I've been running these Buicks since 87. I found a really clean one 2 years ago with a broken motor and decided to just go all out for my final time. It is a money pit. I lost 2 Buicks in my divorce and had to start all over. I refuse to put an LS motor in my car. These Buicks were meant to have the 6 in them.
@@justdust7964 You are correct….these cars just aren’t right without the turbo 6 LC2 engine.
Very nice, running almost the same exact combo as my GN. Except for e85 flex. Got me thinking,. Good content, will be following. 👍
Thanks man! Subscribe and follow along. Next big trick will be going back to a lock up converter and doing various tests with it….
Very nice car!
Thank you sir!
🔥🔥🔥🔥amazing car
Thank you man! It’s a work in progress that never ends.
Love this car!! Not really my liking on the low profile tires, but hey I’m not hating on ya
Looks good brother! You need to come by and take me for a ride.
Absolutely man! I'll hit you up next time I head over to your side of town. Usually its during the week when I come over there.
Has this car ever been at the GS Nationals in Bowling Green, KY? It's THE Buick event that all good-looking Buick perf. cars should attend. Nothing else like it. Larry Rose
No sir. I’ve never made it to BG for the Nats. The car really doesn’t fit any classes to be competitive there. I’d have to change the turbo cover to be legal for THS, and even then it’s probably .5 too slow to be a threat.
I understand what you say here but please understand that there's MUCH more to this event than just the heads up race and three bracket classes. Some specific race classes were formulated by RRA's (race rules administrators) with the input from those who want to build their cars to certain standards to race in a specific class. There's also a superb car show that would definitely showcase your fine GN. And you'll be around 1000's of folks who can truly appreciate your GN. That's what is also very satisfying. Being around all of those great BUICK people. Thanks & Good luck! Larry Rose
🏆
great looking car. looking forward to the next video.
Thanks 👍
Love it ! It's perfect
One of my top 3 favorite cars of all time!
Wish mine was that clean. Need to install my ecu-gn will be looking for your dash vid
Thanks Kurt. Dash vid will be dropping soon, along with 1 wire alternator upgrade vid which is needed when you remove the stock cluster.
Where do you get that "eco-gn"? Is that the one that's supposed "plug n' play" that's also called the "blue box"? I've heard nothing good about that one. They are said to be modified Mega Squirt computers.
Love the car buddy. Almost identical to my vision for my own 87 hard top. Question - what size tire in the rear, and did you mini tub and/or notch the frame?
Thanks man. No mini tub or frame notch. I did roll the fenders with the Eastwood tool tho. Rears are 18x10”, 4.75” back spaced with a 275/35/18 R888R
@@AJsSpeedShop thank you for the info!!
it's a shame you don't have the factory rims it came with on. But anyways in 1987 I owned a brand new Corvette and raced a black car called the Grand National. That day I dropped off the two chicks I had in my front seat went to the Buick dealer and bought one, unfortunately mine had T tops.
That is one beautiful GN what kind of brakes are you running in the front and rear.
Hi! Thank you! I’m running Wildwood Dynalite from brakes and stock rear drums. I keep the drums because they clear the faces of my Weld drag wheels.
Absolutely beautiful build may I ask what the ccw wheel specs are? They fit perfect mini tub?
Hi. No mini tub or frame notch. Wheel specs are:
18x8, 4.5” BS, 255/30/18
18x10, 4.75” BS, 275/35/18
@@AJsSpeedShop thanks so much that’s crazy I would’ve never guessed it was stock no tub great job on the build it’s gorgeous
I don't care how old these cars are. these cars are just so damn cool!!
What offset are your ccw wheels I’m trying to purchase those same wheels for my GN and I will hate to grab the wrong offset….thanks
The fronts are 18x8”, 4.0” BS. Rears are 18x10, 4.75” BS.
@@AJsSpeedShop what tire size do you have on the rear 305/35/18?
@@didiergutierrezbarajas4853 it’s a 275/35/18 rear and 255/30/18 front
@@AJsSpeedShop thank you nice car I’m doing the same set up like yours but leas power I just need it to drive me around and look nice at the same time thanks for your help….👍🏻
@@didiergutierrezbarajas4853 absolutely man. No problem. Good luck on your CCWs. I had a lot of issues with them getting mine right. Took about 4-5 months to get them and send them back to get fixed. I probably won’t ever buy another set of CCWs.
Beautiful GN. Those CCWs look perfect. Is your car mini tubbed?
Hi, no sir. Not tubbed or notched. Just rolled the inner fender lips and wheel well trim moldings. Plenty of room for 275/285s.
Nice ride. Man, I miss my old 87 Buick GN as well :(
What exhaust system are you running?
It’s a 2.5” ATR dual system with old Dynomax UltraFlo mufflers from 1991….it sounds awesome….
@@AJsSpeedShop ok nice appreciate it thanks
Wow that is one beautiful GN, what mods have you add to it, and was a fuel rail i saw or injector rail? How much was that turbo and what additional parts you needed with the turbo? I'm only asking because i'm getting one and don't know if i should get one not to modified somewhat like yours and respectfully taken care of or just get a stock one and mod it myself, it's that i'm in Jurzy and don't know many GN shops, I do own a 2023 M2 and that car is a dream you should try driving one you will fall in love. So yea if you can get at my questions i'll appreciate it.
Sick ride! Have you ever had to adjust the Astro roof? The springs on mine seem to be bad and I’m not sure where to get some
Actually, mine isn’t an original Astro Roof. It’s called a “Sky Top”. The second owner had it installed in March of 1990 by Sky Top in Missouri. I’ve never had to touch it. It works great and doesn’t leak a drop. Hell it works better then the one in my 11’ F150…lol
@@AJsSpeedShop man I wish I could say the same, mine is starting to sag in the back and as far as Ik there aren’t reproduction parts
Did you figure out the thrust bearing issue??
No. Never did. This motor still has the thrust wear problem and it’s a different block/crank/caps from the first few failures. This one still has oil pressure though after 4800 miles so….I’m gonna run it til it dies.
I have a TA aluminum block here ready to build in the future.
@@AJsSpeedShopwhat torque converter are you running?? Could be putting to much of a load and wearing that thrust bearing
Could it be a PTC converter issue?
Did I miss it ? Did you say ms3 ?
No it’s an ECU GN, which does have an MS3 Pro processor inside. It’s made by Turbo Tweak
Beautiful car dude. I have an 87 too except mine has t tops. I had my engine built by Steve V out of Virginia. As a t top car mine is making 450whp. I'm afraid anything more would twist the frame. It's faster than lot of the modern muscle cars on the street. My next project vehicle is a 92 gmc typhoon. Really need an ecu upgrade probably should have had one before any modds where made. I'm doing a complete holley ecu system. I see e85 is becoming the go to for the older turbo vehicles. I'm running a alky kit on my GN. I may just have to e85 conversion on the typhoon. Again great looking GN. You sir have got a new subscriber.
Awesome man, thanks! Yeah G Bodies will definitely twist up, even with the braces installed. A think a good drag bar is the key to keeping them straight. I love Sy/Tys too. Turbo Tweak makes and ECU GN for the Sy/TYs also. Plug it in and go. And yes, e85 with a flex sensor and a modern ECU is the way to go. It’ll really save your bacon when something goes wrong/fails. The o2 correction alone has saved me at least 4-5 times when I had a fuel pump issue and a fuel slosh issue.
Keep following along with me, I have a GOOD vid dropping Friday, and a tech vid that should drop early next week. I’ve got a lot of stuff planned for content. 🍻
Did you repaint this car?
The car was repainted in 2018 before I bought it in 2020.
I just bought one in great shape, just the hood peeled from cheap 80s lacquer and other minor chips on car, I’d like to paint it but afraid new paint would devalue it
Very nice! That digital dash setup sure cuts down on having to have a lot of gauges in the car huh? I bought a similar combo from a guy in Allen, TX...it made 597rwhp@29psi. Looking forward to the dyno vid, subbed.
Yes it sure does. That was one of my main reasons for getting the dash, to be able to display MORE data and have LESS BS in the car. Plus I can log from the dash, tune from the dash and have multiple dash layouts if I get bored with one.
I’m going to be shooting a video of the dash and doing a full explanation and review of it and putting it on my channel in the next week or so. I’m getting a lot of messages about it.
And yes, the dyno video is done, I’ll likely drop it on Thursday or Friday. It will not disappoint…
Thanks for watching my channel!
BADASS BUICK BUDDY!!!!! 😎👍
Thank you man!!
one of the best muscle ever built, design is f a n t a s t i c.
Yeah Buick definitely built a legend in a time where performance was dead.
@@AJsSpeedShopNice
CF5 👍
Sweet build! I'm curious what mine will run whem done.. identical build except i have champion iron heads. Cam, turbo, stroker, E85 all is the same!
Good luck on the new build. Sounds like you have the parts for 9s….getting it done is another story. Takes a lot of testing/tuning, repairing and some luck.
Pushing stuff to the limits will definitely discover the weak links.
Good luck on your progress!
That car looks exactly as I would expect a car of yours to look
Thanks man. Wait til the next video drops on Friday.. It’s gonna be a banger for sure…
@AJsSpeedShop You need to check the clearance with the PTC converters, too tight and it will take out the thrust bearing in your engine. There is a thread about this on the forums.
Yeah I’ve checked everything. I’ve chased this thrust bearing problem for 3 years. 4-5 engine builds, 3 transmissions, 4 converters, 2 flex plates. Clearance set everywhere from 1/8th to 1/4”. I’ve measured and adjusted charge pressure, bypassed trans coolers, tried all different fluids etc…. you name it, I’ve tried it. Still have not found the root cause.
1:28 if it is stock, it would be 231 cuin.
“Stock 109 B L O C K”…. Meaning it is a stock/original engine BLOCK. The block is the only part of the engine that is stock.
@@AJsSpeedShop Cool
Video doesn't do this car justice, even cleaner in person!
Thanks bro…. It’s pretty decent but no where near your level of paint detail and quality. Probably before the Hot Rod Power tour I’ll have it paint corrected and ceramic coated. Thanks for watching my vids!
Prime example of a tastefully and extensively modifying a GN.
Awesome! Thank you!!
250+ci is not stock.
It's a stroker 231. He said the block is the stock "109", :.
This car is awesome! But how in the heck does it still have drum brakes???
I kept the drum brakes because they clear my flat faced drag wheels. If switch to disks, I’ll have to get some Strange or TBM drag brakes so they’ll clear my wheels and they are about $1500 a pair. With all the other problems I’ve had, the rear brakes haven’t been a priority.
