Hey there. I just need some help from you guys with my ac please. I recentlybought a 95 r33 gtst skyline and my first question is if this type of skyline's ac runs off the 134a or the r12? Next the ac wasnt getting cold enuff for me, it was cooling but just not getting cold, so I decided to add more gas to it, i added the 134a and it immediately felt cooler now i have been running the ac for a day now and it blows nothing but hot air I did the diag nostic test and dont know what the results or what im even lookin for all the leds work i figured that out when i put it to 2 i get 20 when i put it to three i get 30 4 i get 41 and 5 nothing happens then six is a setting that you can adjust does ne1 know what this means. also when i tried to gas it first i put the hose on and let out most of the air that was already in it then i added two 12ounce cans of the 134a and it cooled for like a day very very cold i just went on a trip after playing with the diagnostic test and it is now blowing strictly hot air. Can ane1 offer ne solutions.

has it still got gas in the system? sounds like a leak to me.

I have been vexed by the way the auto function works but I think I have it worked out now. When I hit auto at 24c the air comes out the face vents but if i change to 27c it comes out the foot vents until 27c is achieved in car, then it changes to face/foot, and the fan slows to 1 unit, but if the car is cold, it wont up the fan from 1 unit until the motor water is hot enough to do the job. If I want cold air (24c or lower) on my feet I have to overide auto but it still keeps the temp range with the fan going fast/ slow etc.

yea there is gas in the system. i checked the diagnostics all is well checked the sensor on the left side of the steering wheel and cleaned it but still no cold air. i noticed the compressor comes on but then immediately cuts off what causes this and when it cuts on for that split second the little glass window that you check the gas level with is empty when it cuts out it fills up with a white fluid. can my compressor be shot? that would be a bummer cus i was using the ac all this week with no problems. decided to put more gas in it cause it wasnt cold enuff and now it doesnt cool at all. if i let the car sit for awhile and then cut it on with the ac it starts off like its about to cool but after about 30 seconds of that the compressor just keeps cuttin in and out.

also when regassed most of the previous gas was let out by mistake dont know if it was all, attached hose without refill bottle on next end resulting in the gas being let out, then two 12ounce cans (340 grams a piece) of the 134a were put back into the system could the problem be too much gas should i try letting some of it out. If so how do i go about doing this with car and ac on or just letting some of it out with the car off be good enuff?

    • I'd suggest the answer to the first question is at least a qualified "yes". I'll come back to that. Pineapples just don't do a lot to solidify the mounting of the subframe. They do a little bit, and that little bit was clearly helpful to me in the past, but the main thing they are intended to be used for is to tip the orientation of the subframe to try to either dial in more or less anti-squat. You can install them one way to try to increase launch traction, or the other way to try to increase lateral grip (at the notional expense of longitudinal traction). Or, as I did, you install them neutral, which only really offers a little bit of "snugging" up of the subframe. When I did pineapples, that was the only option. No-one had a machined alloy collar like the GKTech ones. There were some other options, but nothing like the slip in collars. And it is clear from looking at them that they occupy almost all the free space inside the rubber bush, so they will do a lot to stop them moving internally. So I thought, "that's the game for me!". Obviously the next/adjacent step is poly bushes, but what's the point in doing that with all the work and hassle required to change them over, when jamming (and I mean literally jamming) some alloy into the rubber bushes probably gives an equivalent, or possibly even superior result? So, to go back to your 1st question, I would suggest, for the investment of <<$100 and a morning spent lying under the car swearing and getting some sore fingers, it is certainly something you should try. Who knows? Maybe your situation is so severe that it doesn't solve it. But it might help a lot. If your problem is as severe as you say it is, the next thing to look at is what the rest of the bushes in the rear end a made from. Things like the Hardrace arms with hardened rubber bushes might be a good thing (for the purposes of having adjustability AND stiffer bushes). Otherwise, just poly bushes throughout could be a help. Or following in my fever dream footsteps and putting a lot of sphericals into the rear? Eliminate undersired movement to avoid the build up of resonances that cause the tramp. Also, if you have adjustable uppers in the rear, and you haven't put effort into adjusting the traction arms to minimise bump steer, there might be some advantage in that. If you don't want to go to the effort of doing it yourself (like I am pretty much forced to in Adelaide, owing to a lack of race alignment specialists) then surely there's a place in Melbs that is able to do it. It will cost $$, But that's life.
    • As someone who has pineapples, and horrible axle tramp... should I change these to collars? Is that what you're saying here? Why did you choose these instead of getting pineapples where you said you had good experiences of? I'd love to even attempt to get rid of axle tramp, I either get complete bogginess or absolute insane wheelspin, anything even remotely in between results in filling-removal axle tramp, to the point where launching the car is just not something I do.
    • Lucky for that, because putting ethanol in fuel only lowers the bulk cost of fuel if it's in 91 Add it to 98, 85% of it even and it quintuples in price. Strange physics. f**k you United, Gouging c***ts.
    • Not noticeably. Arguably, the catless turbo is going to work harder in a different direction, as it will spool up faster, go to higher speeds more easily. Only if it was tuned in the original condition. If it was a stock tune, using the AFM before and after the cat/dump change, then no, no retune needed. If the car is running on a MAP sensor, then it might well benefit from a retune. It might even run a little dangerously without a retune, but it could quite easily be fine.
    • We had this blend that uses 98RON + 10% Ethanol which brought it to 100RON. It's no longer available anymore unfortunately.
