NO RESERVE Very clean, some performance & handling mods, original parts included

1986 Buick Grand National Additional Info:

I bought this car from the second owner in 2003 with 67,000 miles on it, before doing most of these mods myself (rear axle and transmission were professionally rebuilt by well-known GN specialists). It sat peacefully in storage for nearly 10 years while I moved around the country, and I recently moved into the city and I just don't have the time or space to keep it anymore.
I had dreams of building the car for 11's, but I never picked a larger turbo and injectors, but I did a lot of mods around a goal of reliable sleeper. Now I'm kind of glad I stopped where I did with my mods, because everything I did is totally reversible if you want the stock look. The trans has a higher-stall converter, and the suspension is stiffer than most GNs, and no longer handles like a boat.

Suspension & Chassis:
- Energy Suspension Polyurethane body, control arm, and sway bar bushings
- S10 springs up front
- Bilstein shocks all around
- 12" brakes in front on B-body spindles, UB Machine custom control arms, F-body 1LE 12" rotors (retain original bolt pattern), aluminum drums in rear
- Powermaster delete with vacuum brakes and B-body master and slave cylinders
- Line-lock with switch on A-pillar
- Aluminum body braces in key areas (front frame, and trunk behind seat)
- Boxed control arms eliminate wheel hop
- Eaton Positrac installed and all rear axle bearings and seals replaced less than 4,000 miles ago (kept stock 3.42 gearing)
- Battery relocated to trunk for better weight distribution, with dummy battery under hood
- Rear Air Lift air bags
- Larger hollow F-Body hollow front sway bar really cuts out the body roll
- 17" wheels with Continental ExtremeContact DWS tires, about 4 years and 1000 miles ago
Engine:
- Terry Houston 3" Downpipe
- Flowmaster dual exhaust with mandrel bent 2.5" from the Y-pipe with a removable exhaust cutout
- PTE larger stock location intercooler
- Valve springs and timing chain just replaced
- Upgraded Walboro fuel pump and regulator, with voltage boost at WOT
- K&N filter intake
Interior:
- Interior is in VERY GOOD condition- Very rare electronic climate control, which actually works (but doesn't blow cold as it's still an R12 system)- A-Pillar boost gauge
- JVC Head unit (antenna is currently stuck, in case you're an FM radio fan)
- 6x9 3-way speakers installed in the back without cutting any holes in the interior
- Headliner replaced
Exterior:- Body is 100% rust free, including under the doors (pictured)- Repainted for over $3000 around 2002, less than 5,000 miles ago- American Racing 17" wheels, and the original wheels are also included- Front bumper fillers recently replaced, and rear ones are included since I bought a set, but not installed, as they haven't come apart yet. All the bumper fillers fall apart eventually on these cars.
Transmission:
- Performance rebuild by Janis Transmission in Akron, Ohio less than 2000 miles ago (one of the top 200-4R builders in the country, the build was $2,400 without the torque converter, shifts are super firm)
- 9/11 lock-up stall converter with 3200 stall (a bit high for the stock turbo, prepped for a larger turbo I never ended up buying)
- Additional trans cooler
- Driveshaft loop
Recently it seems the stock GN's are more desirable, so nearly all of the original parts are included, including the wheels of course. The only notable original parts I don't have are the radio, exhaust, and the front brakes and spindles. The front suspension components are all the same as any G-body, S10, or Blazer if you love brake fade and want to go back to 10" brakes. The brakes are well-balanced with B-body master and slave cylinders, stopping far better than stock. I still have the PowerMaster brakes if you are suicidal and want to put them back on. Whatever Turbo Buick you do buy, please do not keep the PowerMaster brakes!

All the original wheels are in good condition, one has a bit of curb rash, I don't have pictured. The tires are at least a decade old and should definitely be tossed.
