I just kept my rb20 compressor connect to its lines but removed it from the rb20 block

this way you dont have to regas your air con

dropped in the 25 and mounted it back up

belt size may be different and your meant to hook up a extra temp sensor or something so I currently have no air con

before you start fitting AC compressors look on the back if its designed for r12 or r134a gas.An R32 I imagine would be for the R12 due to its age ( correct me if I am wrong anybody ). I would be chasing up the compressor that runs R134a as you cannot buy R12 anywhere.R134a compressors run at higher pressures, Ac would still work ok I guess with the older compressor but the newer compressors work better..I am doing the same conversion right now in an AE92 corolla...bought a compressor from the 20 valve blacktop..Just shopping around now for newer condensor...good luck

There are 2 different models of rb20 compressors (wouldnt have a clue how they differ)

They both are R12 gas and you'll need to convert the system to R134a if you want to regass it. (aircon mechs do this for a small price, they replace some seals or something cant remember)

R134a is not as cold as R12, so your rb20 compressor will need more effort to produce same coldness.

R33 compressor would most likely be r134a which would be more efficient than a r32 r12 compressor running on r134a gas

added bonus is that the r33 compressor is smaller and lighter :cheers:

I went with the r32 compressor on mine when i converted as all the lines match up, so it's just a bolt up job. Mine was still working well at the time too so i didn't disconnect it. One less complication in the conversion.

If you go with the r33 compressor then you will need to get some custom lines made up to suit so it adds to the cost. Whether the cost of a regas and lines is less than a conversion you'll have to find out for yourself

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
