Hey there I have a 1993 Nissan skyline r33 series one gts and would like to know the amount of r134a gas that is required for the air con system. If anyone can help it would be much appreciated.

does it currently have any gas in the system?

i know a guy who does aircon work and if he can't find into on the system and it isn't working because of being low on gas then he weighs the amount of gas that he sucks out of the system then uses an educated guess as to how much to put back in. i think the fact that a lot of systems use similar amounts makes it a bit easier.

there is no gas in the system as a part had been removed. i have reoiled the compressor and replaced the part. i have also pressure tested the system and all is good there only need to know the amount of gas that is required as it is not on our chart.

a little off topic, but i'd like to know - can you put the other type of gas in? i think it's r12a. (or r12? whichever wasn't outlawed)

apparently the 32 and 33 aircon works more efficently with that gas compared to the newer type.

educated guess i would say 600-750g of gas. R134a and R12 use different oils. ive done conversions from 12-134 but not the other way. 12 is meant to be a better refridgerant but i still wouldnt run it as 134 is effective. there is a sight glass on the dryer to help or gas it up til pressures are correct

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
