I've been thinking about this all day, still not swayed either way. I can see myself (and the missus) appreciating having the air con when staging etc coming into the warmer weather but also see that it IS weight that can be lost and a tiny bit less for the engine to do, though not much as it's obviously only requiring work when it's engaged.

Hmm... lol

Most modern shit cuts the air compressor out on full throttle. I think R32's do this, do S13's?

You don't sound too serious about getting an extra tenth out of your times, and personally, in your situation (already thinking about selling time) I'd leave the aircon in it. Rip the passenger seat out when you get to the track to save 10kg or so......

If you remove the aircon, it'll never go back in mate.

Those complaining that its hot???? Come on guys. I havea std radiator so drive at the track with teh heater fan on high and full blast to try and take heat out of the coolant.

My AC never got regassed after the engine came out years ago, then a line melted with the high mount so out it came, 10kgs is 10kgs

resale and s13 in the same sentance

you guys are f**ked!

But is only ever gets driven on weekends :yes:

If its a track car rip it out and ditch it, chances are who ever you sell it to will use it for the same purposes anyway.

I'll see your permanently on heater (not because the rad can't cool, but because the tap is permanently on) and raise you one glowing exhaust system next to my leg. The rotary exhaust runs so hot I can smell paint on the trans tunnel burning at the end of each stage. Even the handbrake handle gets too hot to touch.

Not such a bad thing in winter, but it gets awful hot in summer (Gallangowan 2008 was a shocker. Even the water out of my camel back drink bottle was coming out hot enough to make a cup of tea)

But yeah - hot and sweaty is so much fun. Lucky I'm such a hard bastard :yes:

Dedicated track car - yeh I'd probably strip the A/C out if it wasn't working well. Anything else and I'd happily leave it in there.

Pull it out and stop being pussy. Silvia's aren't worth shit so why worry about resale. Its only going to go to a skid kid anyway when you sell it so it makes it more drift spec. Win Win.

I just put my battery in the boot so thats 10kg off the front wheels as I had a large battery and moved it as far to the rear left as I could and when I remove the aircon inc under dash that should be another 15kg off the front of the car hopefully.

Weight is weight and I have never seen Ash ever do a trackday so his opinion doesn't count :( Sorry Ash :whistling:

I'm with Bris. Std radiator and heater on FTW!

I'm in a similar situation, thinking of whether to take the aircon out or not. My main reason is to try and get as much airflow to the radiator as possible because out on track the day heat up here is a killer.

Something interesting to add.

I was at a drive course yesterday and had Luke Youldon as my driver/trainer and he insisted on having the windows up and aircon on explaining that the added comfort would keep me fresh and would do far more for lap times than the small reduction in weight would do.

Having said that, once he got out of the car I turned it off and put the windows back down as I prefer to drive that way. It was only 22 yesterday so it was hardly hot weather.

At this stage, it's still in the car.

That aside, just saying it's a valid point. It was interesting to see how some people handled fatigue later in the day, which is when more 'incidents' occured. That will also be car fatigue, tyres etc, also.

Me, i just keep the windows down and kept my sessions to 5-10laps depending on how the car was feeling.

Windows down is far too loud and too much wind to hear what the engine, tyres are doing. Without wanting to sound like a tool, i am basically shit scared most laps i am driving fast so kind of focussed and dotn really notice if i am hot, or the cabin is hot etc. I agree if you are doing races etc. Bt i cant remember the last time i did 10laps in one sitting. Doing 5 laps at a time is a breeze, irrespective of ho hot the cabin may or may not be

I'm a windows down man, but I don't notice the heat in the car unless it's a long straight or it's in the pits really. I really just like hearing my 'gate open up which is better with the windows down :)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
