We established a solution about 7 years ago.
We saw a problem years ago that our stock AC compressors were too complicated and also outdated as well as the rebuilt ones kept failing.
So with the assistance of MustardCat we came up with this.
MustardCat designed a bracket for B-Series/H-Series compressors to be used on the B20a5/21a1 motors.
When I did my first H23a swap into my old yellow 88Si, I used our old stuff and combined with the H-series lines to make a weird mix match hose.
While that worked for a while, I discussed with MustardCat about making a custom set of lines for AC conversiont since I already established we could do it and had it running.
He picked up where I left off and improved on my setup and we tested on his lude and then my 2nd and 3rd ludes and came up with the below solution which is still available today.
By going this route we brought the lude into the 2000's but rewiring and making a custom solution that once its completed can keep stock B20/21 motors running for years to come until they stop supporting the B-Series platform.
Just require custom AC lines which are available for sale from the US.
I used to sell them but since handed all products off too MustardCat, and he sells some of my old work but he builds and maintains his current line of support for all 3rd gens.

Wiring it up is shown on youtube.
The TRS090 AC compressor is the civic/integra/crv/del sol/crx B-series compressor.
