ok so i have done alot of reading on this but im still a little inclear as some say yes and some say no, anyways my aircon hose was melted when i had a screamer pipe on it that was pressing up against it, i dont have the screamer pipe on it anymore and i fitted a replacement hose, so obviously i have no gas in the system at all anymore. I want to get it refilled but im unclear what type of gas to get it filled with, some say its r12 gas that it takes and that they dont use that gas anymore and that i am supposed to have the fittings changed to r134a fittings and that i am supposed to have the compressor modified to take the new type of gas, but then others are saying that it was a scam and that r134a can go straight in it without any modification to the compressor and that i just need to get an adaptor for the fill fitting. At the moment it has the stock pale green cap on the fitting. So my questions are:

 

what gas is supposed to be in it, is it r12?

do they still sell the r12?

is r134a safe to use in it if it was made for r12?

does the r134a rot or seep through r12 seals?

do i have to have the compressor converted from r12 to r134a?

if it was your car what would you do to it?

 

thanks guys

R12 is dead....died with global warming.

R134A is the 'environmentally friendly' alternative, it is not as good cars that were made for R12, but on some later model ones you would be lucky to see a difference.

I haven't heard of 134 affecting seals etc....and yes some fittings have to be changed for 134.

if it was my car I'd take it to an A/C guy [or several businesses] and talk it over with them, his replies and knowledge will help you decide who knows their stuff and who you will trust.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
