well in Japan they have a differne type of gas than is used over here!! the aircon can be filled with normal gas no worries, just have to pay extra to dispose of the old gas!! But should have been swapped over during compliance!

retro fit is not part of complience.

R12 is not illegal to use.it is for sale.and can be used.WHY BOTHER.i havnt seen a can that needed it.if the pressurse were funny/high it mostlikly needed a newTX valves and replacments are R134A set.

to retro fit you replace the reciever dryer[filter] and the new ones are R134A compatible.service valves adaptors[not needed].

OIL[important] if you use other oils or drop in gasses these can effect hoses and orings and worse clean out the scum on the inside the pipes from the old gass and cheep oil.

if you use PAG type oil you dont.its a good idea to replace oring anyway as high pressure tend to melt them.

R12 is over $100 a kg [about the amount you need]

R134A is around $10-25 KG and good oil is up to $40.[need 150/200 ml.

WHY BOTHER with blend gas or hydrocarbon..

panel shops and electricians use all sorts of fad gasses.these still have R12 in them.SP43F is from memory flavour of the month.This is very good in houshold goods im told.

the problem is the oil.ROCK OIL is the common type and aunty ESTER. VERY GOOD IN FRIDGES.

if they were good in cars then the factory would use them.

speaking of regassing, ive got an R33.. takes R134A.. Got it regassed as it started to heat up at the start of last summer.. I use AC only every now and then (robs power) - thought today I would chuck it on AC as it was quite a nice day, and its barely cold :D

the idea of climate control is you leave it turned on.

when not in use it will leakout.compressor seals ect.

6 months.I would say you got a leaking bit,have a good look for oil stain on pipes and conections.oil on the front hub of compressor will indicate shaft seal.

its normal to get small leaks on the cold side of a/c.as they are cold/wet most of the time corrosion and cracks are comon.

ive replace evaporators TX valves and compressors on R33.

leaks on the high pressure sise are normally works today stuffed tommorrow.

    • Apologies for the long post, but needed somewhere to lay out the entire timeline of events and actions taken:   I've got an 89 GTR with a R34 RB in it. It's been running great all year, driven probably 500KM in the last month. It's not my daily driver, just a weekend fun car.    Build info: R34 RB26 - HKS 2.7 stroker kit, HKS adjustable cam gears, HKS turbo upgrades, Trust intercooler, R34 factory DENSO 440cc injectors, JUN chipped/tuned R32 ECU. All of this work was performed in Japan back in 2019.    Thursday 10/2/25 - It's a nice day and decided I'll drive it to work, I start it up in the garage and I notice it took a few extra cranks and sounded a bit funny. I figure maybe it was just because it was a pretty chilly morning. I pull it out into the driveway to warm up a bit before leaving. As I leave the driveway, it feels very off and sounds like a misfire. I pull it back in the garage to deal with after work and take the daily to work. I was able to diagnose it as a cylinder 5 misfire with the old spark plug test (unplugging each plug until a sound change with the engine running). I take off the whole ignition system, ignitor, plugs, spark. *Important note, it is still on the R32 ignition system with the separate ignitor system. I test each system with a multi-meter and nothing presents as a smoking gun. I put it all back together and it starts up no issue. I go ahead and order the PRP R35 ignition conversion kit. It should arrive today (10/13/25)   Friday 10/3/25 - Another nice day, car starts up great and drives great all day. Very pleased that everything seems to be OK   Sunday 10/5/25 - Decided I'll take it to play some golf, load up and drive to the course about 25 minutes away. Drives wonderful the whole way there, I pull in the parking lot and the engine completely comes to a stop. I do not recall if it sputtered at all, but just remember all of the sudden the engine was off. I roll it into a parking spot, try to crank it back on and nothing.  It'll crank and crank and not even try to start. End up getting it towed back to my house and push it up into the garage.    Items I have checked: Fuel in the tank Fuel Pump relay Fuel pump fuse  Spark Plugs & gap Coil packs Ignitor    I know the cylinders are getting fuel as the plugs smell like fuel after a start attempt. I tried spraying starter fluid into the manifold and cranking and not even a sputter.    I decided to do the live CAS test (removing the the CAS, ignition on and spinning the CAS stalk to see if the injectors pulse and spark is active). All of the injectors were pulsing and I have spark at the plug. The half-moon end of the CAS did seem very loose, I'm not sure how much play is supposed to be there, but it was more than I expected. There was no in/out play of the shaft, just the tip end that is pinned on had quite a bit of play.    CAS Play video   When I put the CAS back in, I stupidly did not re-time the engine. I know I need to do that tonight, however, I do not think it will start given it seemingly was not the issue. My plan is to do the PRP R35 coil kit and retime the engine at the same time.    I plan on ordering the Haltech Nexus Plug-in ECU once they are available again, but ideally would like to get this sorted before firing the parts cannon at it and potentially adding more variables.    Anything glaring that I am missing here, I'm a bit at a loss?          
    • Get it on a dyno. Get something logging Consult. Run it up and find out what is causing it.
    • Looking for a plenum for rb25 de+t neo  Not looking to push much power maybe 300kw at the wheels, is there much difference in flow for Freddy “Greddy style” compared to original Greddy or options like Proflow or Otaku garage?    I won’t be porting the de Neo head for now as I think it’ll be fine 280-300rwkw but appreciate the help and any experiences anyone has between them and any advice. Thanks  Looking at this plenum for now below 
    • engine wise almost no mods: stock ecu Greddy front mount intercooler Greddy forward facing intake w R33 TB stock fuel system, stock injectors, rail etc. Kakimoto racing hyper 3 inch exhaust system Apexi intake filter New NGK –R BCPRES (.8 gap) plugs  
    • Nice one @Pac - looks like a fair few 1600's there!
