1987 Buick Grand National
This is a beautiful example of the fastest production car of 1987
with a ton of upgrades including the OEM AstroRoof. The engine has
less than 1,000 miles since being built-out by revered Grand
National Northwest with almost too many aftermarket improvements to
The exterior is finished in black and sits on Corvette style 17
inch aluminum wheels with turbo symbol center cap decals and high-
performance tires giving it a tough, custom look. It is equipped
with the rare Astroroof option that functions perfectly. The trunk
has a carpet covered trunk storage compartment and the engine bay
is detailed just as you would expect.
Under the stock looking exterior is where all the magic with this
car lies. The base of the drive-train is the already potent GN
turbocharged, 3.8 liter, V-6 tied to a 4-speed automatic
transmission and rear-wheel drive configuration. That is where the
stock similarities stop and where Grand National Northwest and a
few other helping hands stepped in to perform their wizardry.
Here is a list of all the upgrades and improvements:
Turbo: TE-44 with TiAL external wastegate, in-cab remote boost
Intake: Cold air intake, intake manifold ported by Ken
Heads: Ported by Ken Bodhaine, larger SS valves, hardened rocker
shafts, custom painted valve covers.
Camshaft: 206/206 Roller.
Fueling: MSD 50# Injectors, upgraded fuel pump, Alky Control
Exhaust: Ceramic coated OEM headers (Pacific Performance Coatings),
ATR downpipe, cat delete, performance mufflers, heat blanket on
downpipe and passenger side header to protect AC components.
Ignition: Custom cut plug wires (GNNW).
Safety: Driveshaft loop.
ECM: Turbotweak chip (with spares), Scanmaster in cab.
Aesthetics: Custom painted valve covers, turbo shield, and brake
AC: New AC pump, charged and tested AC system (Auto Air/Heating),
NOS replacement blower motor.
Inside the car you will find a loaded interior with two tone
like-new seats, console, air conditioning, cruise control, power
everything, custom 140-mph speedometer (Kirban's overlay and
calibration), custom turbo emblem in place of tachometer, new
professionally installed (Sound Advice) Bluetooth-equipped Kenwood
stereo with OEM Premium Sound Package and trunk mounted
sub-woofers, Kirban's aluminum horn bezel, pillar mounted boost
gauge and new weather stripping on the door sills.For purists, the
original, unmodified instrument cluster is included with the
The combination of a smallish turbo, roller cam, and head porting
means it spools hard and fast. It has only been tested a few times
on the drag strip, with the boost dialed all the way down and on
street tires requiring a gentle touch....but it still trapped at
115+ mph in the 1/4 mile.
