I have now taken delivery of my Midnight Purple R34 V Spec.
It is ex Hugh Keir but via Rod Bell Motorsport , the car has been changed as follows.(for me). Standard engine and turbos, different turbo elbows, non V Spec dampers and springs, and a selective boost controller to give .8,1 and 1.1 bar boost. I have retained the large HKS Intercooler and the full Nismo exhaust system.
That therefore is it's spec for anyone interested. It is therefore a kitten against a lot of the cars here but currently feels noticeably faster than my M3 was. Whole car feels great!
Now some questions:
1 How do I learn the options on offer on the dash mounted CRT?
2 I do not believe the A/C is as cold as it should be. Is it easy for ANY garage to recharge the system in a SKyline.
3 Where can I get a "small" front number plate made to mount above the intercooler.

Hi Dave,

Wise choice! I had the privilege of sitting in 666 SKY's R34 recently and whilst I love my R33, I love R34s just as much if not more! :)

To answer your questions,

1) Not sure on this one. :(

2) Any air conditioning specialist should be able to check it out for you. Im not entirely sure if a Skyline tuner will be able to help, or even Nissan themselves. Let me know how you get on since I think I've got the same problem myself.

3) I had my plates made up for me by a company called GT Grafix according to a custom design I sent them by fax (it was even to scale :)) My plate sizes ended up being 14" x 3" for the front, and 14" x 7" for the rear - but I think the R34 sizes might be slightly different.

It sounds like your aircon unit needs regassing. I shouldn't feel too bad, its not an uncommon problem apparently.

One thing I forgot to mention was, you can run diagnostics on the air conditioner by holding down the OFF button for 5 seconds immediately within 10 seconds of turning the key in the ignition (to light up the dash). You will know you're in diagnostic mode when the whole display lights up completely and you hear the aircon unit itself "ticking over".

You can then go through the various stages of testing the sensors, compressor, etc ...

From "The Sky Is The Limit" book:

Sensor check

Sensor check is selected by pressing HOT switch (the red triangle) while in diagnostic mode.
The microcomputer detects whether each sensor input signal is within correct parameters. The
results are displayed on the screen.

If normal, a "20" is displayed.

If abnormal the failed sensor number is displayed. The sensor numbers are as follows:

20 - all is normal
21 - outside air sensor
22 - Inside air sensor
23 - Water temperature sensor
24 - Intake temperature sensor
25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)
26 - PBR
27 - Refrigerant temperature sensor

This should tell you if any of your sensors are faulty.

Mode door position check

(This is probably not the cause of your problems but it is a nifty self check to play with).

While in Sensor check, depress the HOT button again. This will operate the the mode door actuator, and checks the whether the position detection switch is operating. Again the results
are displayed on the display.

If normal, a "30" is displayed.

If abnormal the number of the faulty mode is displayed as follows:
30: Normal
31: VENT
32: B/L (Bi level)
34: FOOT
35: DEFROST/FOOT
36: DEFROST
You should get 20 and 30 for both tests. There are other things you can do as well, but its mainly calibration stuff.

I actually get code 25 on the first test, indicating a problem with my sunload sensor. However, as I later found out you really have to be in direct line of sunlight for this to work. A torch will achieve the same effect. Was quite funny to see my aircon blink "25", then "20" when I shined a torch on the sensor. :)

Always happy to help. :D

I've just found out that Nissan will in fact service aircon units, even on Skylines! (my local one is happy to check mine anyway)

Go to any nearby refidgeration/air conditioning company and they will gas it up for you. Ive done labour work for a refridgerarion company for years whilst studying and Ive gassed up soo many cars, its really simple. If you lived near Coventry I'd do it for you! Any decent fridge maintanance company will charge you about £5 for the gas. Make sure its the right gas though! R22 is used in most older ones but due to the ozone layer being destroyed its been banned...

"The Sky Is The Limit" book -

It mostly covers R32, but has stuff that covers R33s as well (Climate control & HICAS diagnostics for example). The HICAS diagnostics is particularly interesting - I haven't tried it myself but apparently you have to move the wheel from side to side to engage it, upon which your car suddenly starts shaking itself around!

:cool:

Very interesting reading. Tried the aircon. I know that the cooling is not working and the second stage said 3 not 30 but I left it at that.

It will say "3" at first, while it runs its tests.

The first test will also start off saying "2".

While this is happening you should hear all kinds of noises from within the aircon system, when its finished the result code will be displayed which should be "0" in both cases.

ie. "20" and "30"

Im not entirely sure whether my sunload sensor is iffy or not, but it does require a direct line of sunlight to hit it. In other words, there isn't a lot of point running aircon diagnostics at night since you will always get "25" :)

The unit needs regassing anyway. That much I'm sure of. :(
