|You can see the rear spoiler wing in carbon, but the front hood is white|

Towards the end of R32 GT-R production, there was a change to the FIA Rules which essentially eliminated the Group A category by 1993. Cars now had to be even more similar to the mass produced cars they were based on. The result was the N1 Endurance (or Taikyu) race series, and by July 1991 the first BNR32 N1 cars were rolling off the assembly line.
So it was only natural that when the BCNR33 went on sale in 1995, there was already an N1 version available. Now, as to how many N1 cars were actually made remains a mystery that I haven't been able to solve, however my resources list out these technical differences between N1 cars and their regular road car brothers. (Reference: book, "Shingata Skyline GT-R no Subete" (translated - All About the new Skyline GT-R) published by MotorFan magazine on February 18, 1995).
To increase durability:
1. Turbo chargers used metal turbines
2. Thickness of piston second land increased from 4.0mm to 4.6mm
3. Changes to material used in con-rod bearings
4. Strengthened air inlet hosing
5. Use of air cooled oil cooler
6. Larger vanes in water pump
7. Strengthened areas around cylinder boss head bolt boss.
To increase response:
8. Thinner piston ring gap (top and second - from 1.5mm to 1.2mm)
9. Changes to cam profiles (the exhaust side overlap - 0 to 5 degrees)
To increase cooling ability:
10. Placement of 2 engine cooling slits
11. Air ducts in bumper
12. Elimination of screen in bumper
13. Placement of "hood top molding"
14. Use of multiple oil coolers (optional)
15. Change to shape of rear spoiler
CD: 0.35 -> 0.35
CLF: 0.09 -> 0.01
CLR: 0.14 -> 0.15
(numbers are compared to standard R33 GT-R)
16. Use of CFRP (carbon fiber reinforced plastic) front undercover.
Other than these performance upgrades, the N1 car also had no radio, no rear window wiper/washer, no UV blocking windows, no passenger airbag, and no air conditioning, all in an effort to shave excess weight off the car.
Finally, the price of the N1 car was about 1,200,000 yen more than the standard car, and 700,000 yen more than the V-Spec model (all N1 cars were based on the V-Spec). A classic case of "paying more for less"?
So, the only reference to how the hood/bonnet is different is the bonnet lip spoiler, or "hood top molding" as referenced above.
In any case, I had always been a bit annoyed since I found a slight crease on the front right leading edge of my hood - it was ever so slight, but enough to be noticeable. My theory was, someone sat on the hood for a photo or something, and left the crease! Bastard!! And when I approached body shops to fix and repaint, the answer was always - it'd be cheaper to find another hood and paint versus trying to fix the aluminum hood. So I was resigned to trying to find a good quality used hood.
Anyway - just when my car was at Nissan Prince to get the Getrag installed, as I mentioned in an earlier post, I found the unused N1 Bonnet on Yahoo Auctions. So I bought it and had it sent to Nissan to be installed and painted while my car was there.
(again, these were scanned in hence the poor photo quality)
|This is how it arrived at the dealer|
|Started peeling away, good to see the whole thing was bubble wrapped!|
|Nothing wrong here, either!|
|Aha! Someone found a small bump. See it? Nope me neither...|
|The underside looks very clean too.... this will end up painted grey|
|As the wrapping comes off, looks pretty good|
|So this is what makes it an N1 bonnet... predrilled holes for the hood spoiler|
|On the underside, you can see how cleanly drilled out these holes are|
|Fits perfectly, of course|
|Actually, the black looks somewhat good!|
|Wonder why the trunk is open, lol|
And then when I got it back (but before the professional detail job at RAPT):
In any case, the car looks great now, and I can lay claim to having an N1 bonnet. I think if there is any homework for me, it is to explain how this bonnet lip/hood top molding works, although I suspect it simply helps to divert some air underneath the hood to help cool the engine better?
By the way - look what I picked up on Yahoo Auctions the other day (thanks to Miguel and Matty from Newera for helping me push the bid button):
|Brand new N1 rear parcel shelf - note lack of rear speakers and no rear wiper cut-out - not sure if I will install...|
So lucky me, I now have two brand new N1 items... not sure what else out there would work on my car, but might as well collect them for now...
