NA V6 NOTES
1978-83 TURBO V6 NOTES
The following are some things I have learned over the years regarding the 1982 Buick Regal Grand National. I have been an '82 GN owner since 1990 and have met many other '82 owners since then. I would like to thank Al Thompson, Dave Anderson, Dan McCann and everyone else who has shared information with me about their cars. If you know something that may be useful to others, please let me know, and I will include it here.
DISCLAIMER - Although I believe that the following are all true, please verify them before making any decision involving the restoration/modification of your vehicle. If you disagree with something, have additional information, need clarification or have a question not addressed here, PLEASE leave a message on the MESSAGE BOARD!
SPECIAL PARTS and OPTIONS
GRAND
NATIONAL EMBLEMS - The emblems from the '82 were also
used on the 84-87's. They are still available from GM (part
number 25516222). They are placed in similar but not exact
locations as the black GN's. Apparently the emblems were not
ready when the conversions began, due to a disagreement over the
use of the name with NASCAR. The early cars were recalled to have
the dealership install the emblems. Therefore not all '82 GN's
had emblems installed in their proper locations if at all.
LEAR-SEIGLER
SEATS - The Lear-Seigler seat frames are not unique to
the 82 GN. The seat covers however were. The covers when new
appear black and silver, when faded are charcoal and gray.
Contrary to the press kit, The V6 logo
is stitched in the seatbacks on the front seats only. The rear
seat should have covers like the front buckets. A sharp metal
corner tends to poke through the driver's side outside lower
bolster. When recovering, this corner should be padded or
otherwise addressed. Lear-Seigler seats from 1983 Century T-types
and 1984-'86 GN/TR's are similar substitutes, but the backs of
the front seats are cloth and the V6 logo is different.
REAR
WINDOW DEFOGGER - This is one place where not all '82 GN
are optioned the same. Although not listed as a "required
option" in the press kit almost all cars have an electric
rear window defogger (RPO C49). A few, however, do not and this
can be confirmed by the lack of a switch on the instrument panel.
(Had the rear window simply been replaced with glass without the
defogger grid, the switch or at least the hole for the switch
would likely still be there.)
DASHBOARD
TRIM PLATES - The instrument panel, radio trim and dash
plates (bezels) are unique the 82 GN. All are a brushed charcoal
finish to match the other interior trim. They did NOT
have any sort of numbering to indicate which of the 215 GN's a
particular car is. The radio plate is likely to be
missing or damaged by the use of an aftermarket radio. The plate
above the glove box should say "REGAL". A similar plate
with a GN emblem was used on the later GN's (GM 25519072). Note:
Some '82 GN's have the later style plate with the GN emblem. This
was likely owner changed. There was no mid- production change.
The last '82 GN to be converted, C&C #215, has the
"REGAL" plate.
CLOCK
DELETE - Since the ETR radio already had a digital clock
the analog clock in the instrument panel was deleted. The delete
should have the yellow/orange "6" emblem with
"GRAND NATIONAL BUICK MOTOR DIVISION". I don't believe
this part was ever available separately. Note: It is rumored
that some cars were furnished with an analog clock instead of
this plate, but it is not clear whether they were delivered this
way or if the clock was dealer/owner installed.
REMOTE
TRUNK RELEASE - This is another one of those options
that a few '82 GN's seem to have. While possibly original, this
is something that is often added by dealers or at the purchasures
request. The only way to know for sure is to see a window sticker
or build sheet.
GRILLE
and HEAD LAMP DOORS - The grille and head lamp doors are
chrome trimmed with black. They were supplied by Buick and
available as part of the Regal's Sport Coupe Decor Package (RPO
Y44) which also includes completely black tail lamp bezels. (The
GN's tail lamp bezels were the standard chrome.) The grille and
head lamp doors were not available from GM parts division with
black trim. (Paint to match.)
DOOR
HANDLE APPLIQUÉ - The chrome outside door handles had
rectangular decals applied to them. They were charcoal gray to
match the darker paint of the car. These are missing from many
cars by now.
FRONT
AIR DAM - The three-piece rubber air dam was installed
by Cars and Concepts. It is unique to the 82. This is probably
the part most likely to be missing from a car not taken care of.
It is also one of the most difficult parts to find. The center
section is prone to the most damage.
ALUMINUM
WHEELS - These are GM production units (RPO N78). They
are not unique to the 82 GN. They were standard on the 83 T-type
Regal and were optional on other 1982-84 Buicks in, including
four-door Regals. Be careful, similar rims prior to 1982 used a
flanged style lug nut, not the correct conical type used in '82
and beyond.
RED
PIN STRIPING - There are several variations to the pin
striping installed by Cars and Concepts. Most should have a
single red strip running just inside the silver/charcoal boarder.
Some have a double red stripe, or one red and one black strip.
The second stripe may have been added over the boarder to cover
poor workmanship (paint bleeding under the masking tape). There
are different variations to the ending of the stripe at the
bumpers. Also, some cars also have red striping added around the
mirrors, rear spoiler and wheels. This is likely dealer or owner
installed.
STEERING
WHEEL - The steering wheel, column and dashboard where
regular production. They are listed as charcoal but appear to be
black. The wheel, column and dash should all be the same shade of
charcoal/black. The steering wheel is leather wrapped and the
leather covers more of the spokes than later wheels. The center
of the horn button is a black tri-shield emblem. It was also used
on later black GN's (GM part number 25518979).
CENTER
CAPS - The center caps are also unique to the '82 GN,
but are very similar to caps used on other Buicks. The correct
cap is chrome with a black tri-shield emblem. They can be
assembled by using the chrome body of a cap with a colored emblem
and the emblem of an all black cap. These caps have a tendency of
being loose and falling off. One trick is to wrap the the
mounting tabs with a strip of electrical tape to tighten their
fit.
REAR
SPOILER - The rear spoiler was added by Cars and
Concepts. While it is unique to the '82 GN, it is very similar in
appearance to the '84-87 spoilers. They are of different
construction and materials. The '82s are more fragile (especially
the end caps) and do not hold paint as well as the later pieces.
When laid side by side, the outer dimensions of the two are the
same. Since 84-87 units they are plentiful, they would make
suitable substitutes for the original spoiler. Once installed on
the car, it would be very difficult to tell which was used.
OTHER
OPTIONS - While the '82 GN package came standard with
many options, it was not completely "loaded". Some
options you will not find on (most of) the '82 GN's:
DOCUMENTATION
WINDOW
STICKER - This is probably the best form of
documentation for an '82 GN. It will list the VIN number, the
body serial number, the Grand National option package (RPO T2E),
and the dealer the car was delivered to.
BROADCAST
SHEET - Broadcast sheets may be found inside doors,
behind the dash, under the hood insulation (driver's side), or
just about anywhere else. In the lower right wagon section, it
should say "GRAND NAT". The six digit "body serial
number" should match the number located on the upper right
of the trim tag on the cowl. This is a different number than the
last six digits of the VIN. Note: There may be two different
style broadcast sheets.
COWL
TAG - On the cowl tag (under the hood, near the
windshield) should be the codes 84U and 84L for the paint. Maybe
the car was repainted, but the original color was Charcoal Gray.
There should also be an 82 (model year) and CC1 (T-Tops) on the
tag. The cowl tag will not prove a car is a GN, but it can prove
it is not.
VEHICLE
IDENTIFICATION NUMBER - There is no way to decode from
the VIN whether a car is a 1982 Grand National or not. The VIN
should follow the format 1G4AJ474xCHxxxxxx (x = any number). If
the car is a Sport Coupe (Turbo), the format is
1G4AK473xCHxxxxxx. As with the cowl tag, it will not prove a car
is a GN, but it can prove it is not.
RPO STICKER - Looking for the sticker
under the decklid with the RPO codes like the 1984-1987 Grand
National have? Sorry, GM didn't start using the RPO stickers
until 1984. Only the window sticker or build sheet will have the
codes.
RESTORATION
"BUICK"
SHADOW LETTERING - The decals are still available from
the original supplier. If you own an '82 GN, let me know if you
need them. Note: There are some reproductions around that are
black and slightly different size, be careful.
REAR
SPOILER - While unique to the '82 GN, it is very similar
in appearance to the '84-87 spoilers. When laid side by side, the
outer dimensions of the two are the same. Since 84-87 units they
are plentiful, they would make suitable substitutes for the
original spoiler. Once installed on the car, it would be very
difficult to tell which was used.
INTERIOR
SLATE GRAY - The gray interior of 1982 Regal was called
"Slate". It is lighter than the gray used in later
Regals. SEM Vinyl and Plastic Color Spray in "Warm
Gray" (SEM 15183) is an excellent match.
LEAR-SEIGLER
SEAT FABRIC - There is a little controversy about the
cloth used on the Lear-Seigler seat versus the regular production
fabric. The press kit refers to the cloth as "Gray
Brandon". The 1982 Buick Interior trim fabrics, vinyl tops
and exterior color booklet refers to the production cloth as
"Gray Brandon" also. When comparing the production
cloth swatch in the booklet to NOS '82 GN seat covers, they
appear to be identical in both color and texture. Confusion
probably resulted when comparing new, silver appearing covers to
old faded, gray appearing covers.
STILL
AVAILABLE? - Most of the special parts for the '82 GN
were discontinued by GM a long time ago. Now many of the parts
common to all 1982 Regals are also discontinued. I highly
recommend getting what you can now. If you need help finding NOS
(new old stock, discontinued) parts, let me know.
BUICK 4.1 LITRE V6 MOTORS - Finding a
Regal with the 4.1 V6 in the junk yard can be difficult. The 3.8
V6 can be a great source of parts and can be found in many
non-Regal and even non-Buick cars. For interchange, just check a
parts catalog or compare casting numbers (or ask the Message
Board). But for those parts special to the 4.1 V6, here
is a list of GM cars
which used the 4.1 litre V6, courtesy
of David Chase, Silver6.
QUADRAJET CARBURETORS - Both the 4.1
and Turbo 3.8 use a quadrajet carburetor. The production number
is located on the left side of the body. According the the Buick
Pats Catalog, the 1982 4.1 V6 may use either 17059325, 17082268,
17082248 or 17082299. The Turbo V6 uses either 17082244 or
17082260. Note: all number may not apply to the '82 GN, since
they were produced in a short time frame.
ELECTRONIC SPARK CONTROL (ESC) - The
ESC system is what made the turbocharger practical for Buick's V6
application. This same system was added to the 4.1 V6 in 1981.
The system uses a sensor to "listen" for knocking. When
knocking is detected, the ESC retards the engine's timing to
prevent it. The more knocking, the more retarding of timing, the
less performance. To avoid knocking (and therefore maximize
performance) use premium, high octane, fuel. The higher the
octane, the greater the fuels resistance to detonation. See the KNOCK, KNOCK page for more detailed information.
MISCELLANEOUS
PRESS
KIT - There appears to be two press kits for the 1982
Grand National. One is the '82 GN Dealer Press
Kit which is dated February 8, 1982. It contained several B&W
pictures, a two-page explanation of the car, two page options
list, an order form and two newspaper ads. (This kit has been
reprinted in Steven Dove's Facts and Figures Book.) The second is
a Media Press Kit that is dated for release on
February 10, 1982. It contained a B&W 8x10 and a different
two-page description of the car. This was probably given out at
the 1982 Daytona 500 introduction.
INVITATION
- In addition to the Media Press Kit, there was A SPECIAL INVITATION given out to the
media to come see the car at the Daytona 500. This helps support
that the Daytona introduction actually happened.
THE
1982 GRAND NATIONAL PROTOTYPE - Almost all printed
pictures of the '82 GN are of the prototype car. The prototype
had different fender emblems, a one piece air dam and N78 wheels
that used the flanged style lugnuts. Before delivery to Buick,
the car had Uniroyal Steel Belted Radial tires and standard
center caps with the colored tri-shield emblem. Note:
According to research by Alan Thompson ('82 GN Registry), the
prototype did not have a VIN. It could not be sold to the public.
It was used at the GM proving grounds to haul parts around and
was later destroyed.
GRAND
NATIONAL FENDER DECALS - A number of '82 GN have
"GRAND NATIONAL" decals on the fenders similar to to
the prototype's. These are likely owner installed. According to
C&C President Dave Draper, this decal was not approved by
NASCAR, and therefore no cars could be sold this way. Source:
Al Thompson, '82 GN Registry.
"1982
GRAND NATIONAL SPORT COUPE" - This name refers only
to the few 1982 Regals that came with both the
Grand National (RPO T2E) and the Sport Coupe (RPO W11) packages.
It was previously estimated that sixteen 1982 GN/SC's were made.
The actual number of '82 GN/SC's is slightly higher, probably
between 20 and 25. Many times 1982 Turbo Regals (Sport Coupes)
are mistakenly called "Grand Nationals".
GRAND
NATIONAL LIMITED? - It has been reported that some '82
GN's were based upon the Regal Limited and could be identified by
a Regal crest emblem on the C-pillar. There are some '82 GN's
with C-pillar emblems, but that doesn't make them a Limited. The
fifth digit of a Limited would be an "M". There are no
registered '82 GN's with a Limited VIN designation.
1982
vs. 1982 1/2 GRAND NATIONALS - Different names for the
same car. The '82 GN was released mid-year, and many times the
"1/2" is added to signify this. I have seen both ways
used by Buick. Sometimes a major change will occur to a model and
the "1/2" will signify if a particular car has the
change or not. (When the 1996? Regal GS received the superchagred
engine, it became the 1996 1/2 Regal GS). I prefer the '82
without the "1/2" since there was no major change made
to the GN (and it is easier to type!).
