Lately, from various people there seems to be some interest in the Series 3 R33 GT-R. For those who don’t know what a Series 3 is, the informal nomenclature refers to the 1997 and 1998 R33 GT-R models, ie the last 2 years of production. During its production, the R33 GT-R evolved, with various (mostly cosmetic) changes being made both for the 1996 model (Series 2), as well as the Series 3 models. I was going to write only about the Series 3 on this post, but decided as I was writing this that it would be best to highlight all of the changes throughout the production, to demonstrate the differences clearly.
For example, one well known difference is the rear fog light that replaces the right side back up lamp:
Obviously, the Series 1 (or “zenki” [前期] model in Japanese) is the R33 GT-R in its original form. Introduced for the 1995 model year, the comparisons being made at the time were naturally against the R32 GT-R (how it was larger, heavier, but faster and better handling, etc). It is important to note for all R33 GT-R fans that, it was this zenki model R33 GT-R that set the under 8 minute record at Nurburgring. The modifications made later are obviously not those that required significant capital and resources for Nissan to implement. Which really is another way of saying that the Series 1 models were so good that, most improvements in the Series 2 and 3 were really only cosmetic!
Some General Stats:
Total number of R33 GT-Rs ever made: 16,250
(compare this with 43,934 R32 GT-Rs, and 12,175 R34 GT-Rs)
Standard cars: 9,871
V-Spec cars: 6,551 (including N1 versions)
Number of cars by model year:
1995: 8,446
1996: 4,093
1997: 2,708
1998: 1,175
Note: These numbers I copied out of GT-R Magazine. Don't ask me why they don't add up!
R32 GT-R vs. R33 GT-R:
According to my resources, (catalogs and third party books), some of the less obvious differences between the R32 and the R33 are:
1) Elimination of telescopic steering
2) Smaller trunk space due to relocated battery to rear, and strut bar
3) Smaller gas tank – reduced from 72 liters to 65 liters
4) Elimination of the Active Sound System that came with the R32’s stereo.
5) ECU changed from 8 bit to 16 bit.
BCNR33 Series 1 (前期 or "zenki"):
For the Series 1, the available colors were as follows:
LP2 – Midnight Purple
BN6 – Deep Marine Blue
QM1 – White
KL0 – Sparkling Silver
KN6 – Dark Grey Pearl
KH3 – Black
AN0 – Super Clear Red (special order optional color)
The Series 1 chassis numbers range from BCNR33-000056 to 009270 (and apparently with numbers 000094-000100 missing!)
BCNR33 Series 2 (中期 or "chuki"):
For 1996, a few improvements were made to the car:
1) The addition of a front passenger airbag as standard (it was a factory option in the Series 1)
2) The change of the driver steering wheel from a large airbag type to a more compact and sporty type

3) Changes to the shape (more 3-D) and material (cheaper feeling apparently) of the dashboard surround
4) Center console is shallow compared to before (could file CDs upright in the zenki one - reason why is the addition of an additional airbag computer underneath)
5) Deletion of coin slot next to power mirror controls
6) Rear antenna switch moved from above left knee to left of steering wheel behind wiper stalk (replacing the blanked off switch)
7) Changes to the rear finisher (the “Skyline” lettering under the trunk is more pronounced).
8) A special “LeMans” edition car was released in limited numbers – its color was Champion Blue and the car had N1 ducts in the front bumper, a carbon fiber center rear spoiler with adjustable flap, hood top molding, and special commemorative stickers on the C-pillars. These cars were offered for sale only over 2 months during the summer of 1996. [Note: a FAST look-up shows a total of 177 of these cars were built.]
Available Colors:
LP2 – Midnight Purple
BN6 – Deep Marine Blue
QM1 – White
KR4 – Sonic Silver (replaced KL0)
KN6 – Dark Grey Pearl
KH3 – Black
AR1 – Super Clear Red II (special order optional color) (replaced AN0)
BT2 – Champion Blue (for LeMans cars)
The Series 2 chassis numbers begin at BCNR33-021001
BCNR33 Series 3 (後期 or "kohki"):
But then in 1997, Nissan made more than a few improvements to the R33.
The Series 3 is the only one that came standard from the factory with:
1) Xenon headlights (which also means that unlike the others, once on they always stay on, even when using the high beams at night)
2) Larger front lip spoiler (an additional 20mm) – (but with an option to order the shorter one from the earlier models). This also means larger brake cooling ducts.
3) N1 ducts in the front bumper
4) Left side turn signal “grill” is cut out for maximum airflow to optional oil cooler.
Here is a photo of the front of my car, you can see all of these above changes:
5) ABS braking system actuator unit is smaller, with reprogrammed logic to improve stability in braking while cornering situations.
Compare the Series 1:
With the Series 3:

6) Right rear back up light changed to a rear foglight (see first photo above)
7) On braking, only the outer rear taillights light up (not all 4):
8) Door window glass changed to “long life hydrophobic glass”
9) All glass received an anti-UV coating.
10) Interior (seat, door trim) with red accents instead of blue
11) Changes to dashboard facia material texture (somewhat rough tactile feel)
12) Additional bracing in the trunk rear floor area attaching the rear suspension mount to the floor in order to improve the car’s rigidity. Said to be the equivalent of adding another strut tower bar, and also has the added benefit of strengthening the rear crumple zone.
Available colors were the same as for the Series 2, except there was no BT2 color.
(Edit: As Sean Morris reminded me below in a comment, some of the very last cars were available in an R34 GT-R color, GV1 Black. Thanks Sean!)
The Series 3 chassis numbers range from BCNR33-040001 - 043743 (this includes the 4 door R33 GT-R produced by Autech)

So I think that's it! IF I missed something, please let me know. OR if there is a photo of something that should be added here, let me know!
