Long time no update. Been running without a coolant overflow tank for like 14 years... finally made one:

Re relocated my battery back to the front, but I'm using a smaller 51R battery now. There was just enough room to fit it in front of the transmission:

Stumbled across some threads about aftermarket cams eating the exhaust rockers on H22s. Solution seemed to be using an oil with high zinc phosphorous (zddp) content and plumbing extra oil to the head. I've been using Brad Penn oil since the swap so the ZDDP part was already good. Today I added a 3an line to the head, hopefully no damage has been caused before this and the extra oil keeps the exhaust cam happy.

I also gave the bay a clean for the first time this year:

Next big project has begun: A/C

This system is going to use an OE compressor and evaporator but pretty much custom/universal everything else.



First problem; I went to mount a new compressor on the H22 but discovered that even with my custom engine location there wasn't enough clearance. So I did what I always do; cut up the stock part modified it:

Image

Image

Image

Image

Image

Image

Image

Image

Image




I ordered a universal condenser that should fit and it even has a built in drier so I don't need to find a place to mount the massive OE one. It's is also a parallel flow type condenser so it's more efficient than the crossflow type 3G's came with.

I also discovered that Honda used standard threads/fittings on the A/C components which saves me the trouble of welding new threads onto the evaporator. FYI the top port on the evaporator is a #10 and the bottom a #6.

The condenser and some other bits won't be in until next week but I was able to test fit the service ports and start looking at hose routing:

Image

I also received a case of industrial envirosafe refrigerant, I'm interested to see how cold this stuff gets compared to the regular.



The rest of the day I spent redoing my P/S system. I moved the reservoir further away from the pump and routed the other hoses through the fender area.

Saw an Eric the Car Guy video on cleaning condensers with this stuff a while back and decided to try some on my evaporator. It did seem to work pretty good:

Image




Evaporator box done and installed. If I'm lucky I won't need to touch this thing again for a long time:

Image

Image



I welded some #8 and #10 threads onto the compressor fittings so I can screw the lines on. The only other welding I should have to do is welding on the pressure switch port.

Image

Image



Here is how I am planning to route the hoses. They come out of the evaporator, down the shock tower, around the transmission, under my new battery tray, then run along the bottom of the radiator. This keeps them fairly tucked:

Image

Image



I also did the wiring modification for single wire compressors. Problem was when I went to test it the clutch wasn't engaging. After lots of troubleshooting it turns out I screwed it up years ago when I installed my Rywire harness. It wouldn't have been so hard to figure out except that the A/C wiring diagram in the manual has an error which was very inconvenient.

Small update, I got the weld in switch port and a universal binary switch:

Image
Image

Unlike the original port this one is male and uses a schrader valve. This way I can replace the switch without losing refrigerant. The universal switch opens at similar pressures as the stock one but unfortunately the stock connector doesn't fit on it so I will just have to use some female disconnect terminals.

The condenser is supposed to be here on Thursday. I also ordered some 10" fans that I am going to mount on it as pushers. My current 12" fans won't really fit on the front without a big rework of the hood latch. (The 10s will probably still require some modification.)

Here is the new condenser mounted. The mounts on each corner are just some spare end link bushings I had, they just happen to fit into the recessed portion on each corner:

Image



I did a little more welding than I first planned. I joined 2 #6 90° fittings with some #8 tube and then welded the switch port onto the middle:

Image
Image



All the A/C lines after crimping:

Image



Final install:

Image

Image
Image

Right now I have a vacuum on the system. If it holds overnight I will charge it in the morning and see how it does tomorrow (going to be in the 80s).



Still working on the fan situation. I did a little mock up with cardboard and I think I will be able to do a shroud. One of my current 12" fans should fit on one side but I may need to step down to a 10" on the other:

So update on this A/C stuff. Last weekend I got it finished, charged the system and... no worky. After spending most of the day rechecking everything I did I eventually determined the brand new GPD compressor was no good. It was turning on but the low side wasn't coming down enough, only to like 45-50psi when it should be ~30psi.

Problem is when I bought it I could only find GPD, UAC, and Four Seasons brands listed for 92-01 Preludes. Well after a ton of time on the Google I found the Denso 471-7052 compressor (made in Japan baby). It's listed for the 2001 Civic not the Prelude and there is a small and kind of silly reason for this.

Image

Image



Now here is why this Denso compressor isn't listed for the Prelude. On the back just under the top right mount bolt there isn't as much of a recess (Denso at top):

Image



Because the H22 A/C brackets have small tabs on them to help when installing the compressor this means the Civic compressor won't sit flush:

Image



The solution is as easy as you are thinking, a few seconds grinding down the top right A/C bracket tab and:

Image



Aww yiss. The only other small differences I noticed between the GPD and Denso are that the Denso uses studs to hold on the fittings (which can be removed and replaced with bolts) and the wire is a few inches shorter on the Denso.

I put in 1 can (6 ounces) of industrial Envirosafe and it was blowing nice and cold. The sun was already down though so I put in a few more ounces from another can and will be testing it again tomorrow in the heat. I will be working on finishing the fan shroud tomorrow as well.

And it's done. The fan shroud got somewhat elaborate so it took me a bit longer to do but it is all together and I did a few mile test drive today - it was so cold I had to turn it down. I'm going to do a proper long test drive tomorrow.



Here is the fan shroud/air duct. I was able to fit one of my nice USA made 12" fans on the right and a cheap 10" on the left:
Image
Image



Clearances are quite tight on the car. I had to shave down the fan housings, hood latch + support, and P/S cooler fins to get everything in:
Image
Image
Image
Image



Also made a heat shield for the compressor:

Did some quality of life improvements to the interior.

Added a cig lighter port to the side of the console area:
Image
Image



My roll bar slightly blocks the view from the rear view mirror, so I made a spacer to lower the mirror:
Image
Image


I welded some material to the gas pedal to push it out a little and make it easier to heel-toe:
Image
Image



Also did a video on the custom AC setup in case anyone wants to do something similar: https://youtu.be/gXvup7p4S1E
