So it began today and I’d call it a productive day since the shell is in the bay behind the frame. I pulled the good frame outta the bad body first because I figured It’d be nice to pressure wash, sand blast, and POR-15 it all before I put the good shell back on it. When I started this afternoon the car was a shell with no nose (bumper and header panel), engine, Trans or driveshaft. My goal was to at least strip the car of all the good parts, get the front end apart, and spray the body bolts so they would come out easier.

First I unbolted the inner fenders, outer fenders, and wheel wells as one piece and I think that saved me a couple hours if I were to try to pull them out individually. There were three bolts up front that held on to the radiator support, two next to the hood hinge, one under the fender going straight up and two more that required an extension and the door to be open. These last two are between the door and the fender. Once all those bolts were removed their where two or three in the area of the charcoal canister/Battery. Finally there is one in the wheel well towards the rear center of the wheel well. With them off to the side I didn’t like how the radiator support was swaying in the breeze so that was next. Surprisingly both bolts came out easy but the mounts are pretty bad like I figured so going to be calling Kirban soon. With that off to the side I decided to take off the doors. The shell had power locks and windows so those wires had to be dealt with. There is a black rubber seal that goes between the body and the door that houses the wires and plugs. Two screws out and two plugs unclipped and the doors are ready to come off. I found the easiest way to do this is to close the door completely and take five of the six bolts out, leaving an easy exposed bolt for last. Then get someone to help you because these doors are heavy as hell. Slowly take the last bolt out and have them hold up the front part of the door. Once the bolt is out, open the door and it’s off.
Next, I decided to remove the wiring. This section may be different for your car because this car never had a motor in it but I installed all the wires to where I thought they should be. I started in the engine bay with the main junction box. This is located below the wiper motor. I think it’s a 6mm bolt in the center of everything and one that’s out the plugs actually push out of the clip. Now the headlight wiring harness was out and also the main engine harness was too. Next came the computer wires. This is located on the other side of the engine compartment at the bottom of the firewall. If the wheel wells were in you would never know it’s there. These wires have a bracket with two small screws that hold it close to the firewall. Once these are out, go in the car and remove the kick panels and unplug the computer. Now you can pull the wires through the firewall and be done with that. Then I went into the car. I previously put an 87 GN wiring harness into the regal dash and wasn’t about to send a perfectly good, uncut harness to the scrap yard so that had to come out. Once all the wires are separated your almost there.
Then I disconnected the brake lines at the master cylinder and wrapped a rag around the master cylinder just so it all didn’t leak out all over the place. Then I put the car up on the lift and figured it’d be easier to cut the rubber fuel lines that go from the metal lines from the tank to the metal lines on the frame rails. They were dry rotted anyway so no need to be careful with something that’s getting replaced anyway. With that disconnected the only thing left are the body bolts. Also the E-brake cable has to be disconnected. There is a clip that is behind the driver side kick panel that has to be removed to pull the cable out. Once the cables disconnected pull it through the body and that will stay with the frame.
(Just realized if your car has bumper fillers you need to pull the bumpers off or else you’ll break them separating the body. Your best bet is to pull the bumper fillers off the car just to make sure they don’t break)
After spraying the bolts down with PB blaster I went around and hit them with an air gun and they all came right out except for the driver side one behind the wheel. It ended up spinning and when I looked up it rusted out and came out. Once all the body bushings out I centered the body on the lift, not the car. Since our cars frame goes right along the edge of the car here is where you have to take your time and triple check everything. I put the arms of the lift on the pinch weld making sure when it went up it wouldn’t catch the frame. Make sure where ever your lifting the body, the points are as far forward and back as possible to make it less tippy. Slowly lift the body and make sure there’s nothing else connected to it. Once the body’s off I rolled the frame out of the way and “Removed the body”:p...Any questions let me know, Ill keep this as up to date as possible but I can only work on it on weekends. If anybody wants to see something specific I can post a pic of it.

Oh and thanks for all the followers too:biggrin:
 
Here's the aftermath of one night:eek: The car was loaded on to the trialer right from the lift and is ready for the scrap yard. If anybody needs metal for anything let me know or else its all going to the yard

before you scrap it..
you're going to need the inner floor mounts for the buckets and the console floor mounting pads

also the ac box is a little different on the bottom half and the top half is turbo only , and the ac eveporator also is specific

if sticking with powermaster youll need to keep the brake pedal

and if you havent already pulled it youll need the dash , rear body and tail lamp harnesses
and the straps bolts and spacers for the tank and steel lines off the trunk floor

I think you might be a little confused on my swap. Im going from a N/A Regal to a GN so all the interior is already their. The ac box is already their, it was powermaster but I already have the entire vacuum set up, Dash is their, harnesses are their, and so is the gas tank. Thanks for your help tho, all this stuff is the reason I bought a GN nd getting rid of the regal:biggrin:
 
Got most of the engine together after work during the week so hopefully that will be done this week. Made good progress on the body as well. I pulled the power locks, power windows, and wiring out of both of the old doors and the started to put the new doors together. Not long after looking at the new doors did i realize that I also needed the internals of the door to do the swap. I ended up pulling glass and all out of each door, cleaning up the old tracks and greasing them up then putting them in the new doors with the best glass. As a side note does anybody know of a better way to get the window motors out beisdes a hole saw??? it works amazingly but I say poorly designed doors. The passenger side botom had a coupld holes and scales sections of rust on the bottow end so cut patch panals out of the old doors and got that all fixed up. Hopefully next weekend I can attack the frame with the sandblaster and get it POR15'ed so I can finally get the body on its new frame.
 
Got some more progress done this weekend. Once I removed everything from the frame I realized two of the body mounts were rusted away and needed attention. Looking around the shop I happened to find a washer that fit in what was left of the hole pretty well. Welded that in that had to make a patch from scratch for the other hole. Found some flat stock laying around so I used a hole saw to get a piece to fit just right. Once both patches were welded up it was time to start cleaning and stripping. Five bags of play sand later it was all clean but alot of imperfections I didnt like. Around most of the welds were little balls where the welds splashed so I grinded all of them down. Also went along and cleaned up the factory welds. Once the cleaning was done and the frame was wiped down the painting begun. I used semi gloss black POR15 and cheap paint brushes. If using POR15 always use cheap beushes and where gloves because this stuff will not come off haha. Did one thick coat at first and did not like how it came out so after a second coat it looked alot better. Next step is front suspension and making up some fuel and brake lines.

Got all the rust taken care of this weekend. Had some spots under the t-tops which caused some rust on the driver side floor. Was waiting for a member to cut their roof apart and donate the parts but didnt feel like waiting any more so made my own pieces. I got all the pieces welded in and looking good but not ground down so dont doubt my craftsmanship :D

Okay so this past weekend I got all the new poly body bushings including the GNX bushing. this actuall went pretty easily. I thought it was gonna be alot harder but installed all new grade 8 bolts to avoid the the damage done to the bolts I pulled out, which were almost non-existant. Next weekend the motor's going in so I decided to put the inner fenders and core support back in just so I could rest a hood on top of it and keep the rain out :rolleyes:. Interior floor is completely rhino-lined to take the noise away and also if it keeps truck beds from rusting I figure if for what ever reason the carpet gets wet the floor will stay perfect. Once the motor, and trans are in, only thing left if hooking it up and reassembly.
 
Where's the pics? I'm looking at doing some sort of bed liner treatment as well so I want to know how you like it once you get her driving again.
 
Will do. Never rode in a GN before so the comparison may not be the best Haha. However we did do it on my dads dart and it was noticeably quiter and even cooler. I also have a t-top car so I'm always afraid of water getting in and rotting the floor out so this way the carpet will stay wet and I can just dry that out instead of the floor getting it all.
 
Might want to see if you can spray in the A pillars and the roof as well. That would keep the rust out of the important areas.
 
Did you box any of the frame at all? Or were you thinking about it?

I didnt box any of the frame rails because first off Im not really going to be making that much power lol. I am planning on putting a roll cage in it and making up some frame stiffening bars. I also went through and rewelded everywhere on the frame I could. Ground down the factory welds as well to make it look better too. Im a mechanical engineering student so testing what I learn seems to be a good idea...as long as I pay attention haha
 
Okay so Febuary is typically a slow month for our shop every year so luckily that means for the past two weeks my car has been sitting inside on a lift also giving me time to wwork on it during the week. The bedliner in the interior worked great and would suggest it to anyone because not only is it incredible easy to do, but works as a sound deadener. Also got the motor dropped in along with the trans and most of the wiring is together. Ive never worked on a GN before let alone installed an older fuel injected motor but knock on wood its actually pretty simple. With three giant boxes of parts, hoses, nuts, and bolts its a good thing I can look on the forum at other peoples cars and figure this stuff out lol. Also ran out to Kirban's today to get some parts so hopefully I can get the turbo on tomorrow and finish up the wiring. Also ignore the rust in the radiator, I just put that in for the first start up, I have an aluminum radiator waiting and I am going to clean everything else around it up.:D

Quick question to anybody reading this. In the pictures their is a wire that I cannot figure out what it goes too. It is behind the coil and it is attached to the blue tape in the engine picture. Let me know if you know what this is cause I cant find anything near it to plug into.

If im not mistaken its the harness for the EGR Vacuum Control Valve. If you are not gonna be using it tape it up it has a 12v hot on it and tuck it away.
DO NOT forget and make sure your ground wires are attaached to the back on the Passanger side head. The copper ground goes to the top of the bellhousing bolt on the passangerside top.

You are correct and its all going to be hooked up. I dont know enough about turbo buicks yet to start pulling pieces off. Ill wait till I know whats needed and whats not. As for the ground wires from the harness im going to attach them down below the motor (on the body of course) but out of sight. I painted the firewall and really dont want to grind the paint off.

but today I got the carpet in, computer wired up, belt and O2 sensor in, driver wheel well...Hopefully this weekend itll be running.
 
Okay so sorry for the lag in updates but slowly work has been getting done. Slowly bolting the motor together and gettiong close now. Unfortunitly I was an a$$hole and broke my power steering resiovor and found a broken wire on my cam sensor so no start yet but parts have been ordered. GN1 performance hise couplers and and MAF pipe. Wheel wells are in and all the little stuff is bolted up. I ran the headlight wires and most of the other wires. Couple questions though and hopefully some experts can help me out. In the one picture I have multiple wires and I dont know where they go and what they do. Also On the wastegate sensor their are two hose nipples, I know where the one goes but what about the other. Also what connects to the valve in the heater hose. Their are also three wires coming up the passenger fender and a hard vacuum line? Finally where the MAP sensor is supposed to be their is some other sensor with a vacuum nipple, is this wrong or in the wrong spot.
