Ok well when getting my 96-97 b18c swap its going to come with a a/c compressor, my 88 SI currently has a/c but its all leaked out and will need an over haul (line has small hole in it). so my thought is why not just go with the r134 compressor that comes with the engine rather than run r134 in the old r12 compressor. I plan to get a new condenser, evaporator, expansion valve, and drier as well as O-ring kit, and conversion fittings other than having the new compressor's fittings welded onto the old crx A/C lines and removing the long lower mount bolt off the jdm b18c a/c bracket is there anything else to do or note? I know ill need to change the connectors going to the compressor as well. I read in another current a/c thread i will need extra oil for the compressor?????? Im not an a/c expert so all help is appreciated. Thank You

I'm actually going to be doing the same thing, I figured the only thing that you'd need to do is get custom lines to and from the compressor. You would be adding the amount of oil the integra calls for

Probably just converting the lines is all you need to do, but getting the old R12 system closer to the design of a 134a system by adding a parallel flow condenser and the correct filter/drier might help you in the long run. Feel free to review my current thread where I add a NEW Sanden 134a unit (From EG-97-2001CRV), install a parallel flow condenser, and a 134a compatible drier. I've yet to have it charged due to the holidays and am by no means an ac expert, but was tired of seeing people buying used/reman TR70's that fail. Hope it helps you. https://honda-tech.com/honda-crx-ef-...r-crx-3214534/

Using the B-series compressor is the way to go. I don't know if your build includes a traction bar, but you may need the extra clearance depending on engine mounts. I also had to flatten a spot on the frame by the pulley for belt clearance. You may have to remove the condenser fan or use a pusher fan because of header clearance. The hoses or conversion fittings are the hardest part, wiring is easy.

Which car / year model drier and condenser should i order?

Also im currently running the innovative mounts traction bar and will be running their billet mounts as well.

*Edit* Not sure how the traction bar and all that will/would affect the set up as I'm not familiar.

Well I'm not running a B series motor but the 97-2001 B20 CRV used the same series Sanden Compressor as the D series EG. So I would order a CRX Parallel Flow Condenser, R134a compatible Drier, then use the CRV bracket (Assuming the B20 bracket is the same as B18C) so you could run the Sanden 4993 Compressor which is made for R134a. You'll still need line modification to connect the lines. I got my new Original Sanden 4993 at acparts.com for a very fair price and is truly NEW not a copy remanufactured unit. You'll need to call them as the newest Sanden version 4993 is not on the site. The older version 4955 is. I don't know the difference between the two, but I figured the new one may have improvements to it. I would not call their toll free number as last time I did I got a private residence.

Not the same, the B20 uses an a/c bracket made for d series compressors...the B18C uses a true b series compressor that's larger

I was planning to use the jdm a/c compressor and bracket that comes with my type r swap, i guess the question becomes what year did japan start running r134

JMZ400

I guess then to me as long as the CRV bracket bolted to the B18C, allowing one to use a D series compressor which is smaller according to you, would be helpful in this situation where space is almost non existant.

For me "real question" is: Going forward what compressor is more readily available and affordable. The Sanden 4993 can be bought NEW FROM Sanden for $320ish and about $100 less from ACParts.com
