Beautiful car with performance and handling mods, all original parts included!
1986 Buick Grand National Description
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). I had it in storage for nearly 10 years, and I recently moved into the city and I just don't have the time or space to keep it anymore.
The car was built for 11's, but I never picked a turbo and injectors. The trans has a higher-stall converter, and the suspension is stiffer than most GNs, and handles like it's on rails.
Suspension & Chassis:
- Polyurethane body, control arm, and sway bar bushings
- S10 springs up front
- Bilstein shocks all around
- 12" brakes in front on B-body spindles, custom control arms, F-body 1LE 12" rotors (maintain original bolt pattern), aluminum drums in rear
- Hyrdroboost delete with vacuum brakes and B-body master and slave cylinders
- Line-lock
- Aluminum body braces in key areas (front frame, and trunk behind seat)
- Boxed control arms to eliminate wheel hop
- Eaton Positrac installed and all rear axle bearings and seals replaced less than 4,000 miles ago
- Battery relocated to trunk for better weight distribution, with dummy battery under hood
- Rear air spring airbags
- Larger F-Body hollow front sway bar
- 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
- PTE larger stock location intercooler
- Valve springs and timing chain just replaced
- Upgraded Walboro fuel pump with voltage boost at WOT
- K&N filter
Interior:
- Rare climate control, which actually works (but doesn't blow cold)- A-Pillar boost gauge
- JVC Head unit
- 6x9 3-way speakers
- DirectScan scan tool- Headliner replaced
Transmission:
- Completely rebuilt by Janis Transmission in Akron, Ohio less than 2000 miles ago (one of the top 200-4R builders in the country)
- 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
All the original parts are included, and the wheels, except the front brakes and spindles, which are the same as any G-body or S10, readily available if for some crazy reason you love brake fade and want to go back to 10" brakes. I still have the PowerMaster brakes if you are suicidal and want to put them back on.
