I only need the AC about twice a year up here in Norway, but I want to keep the system for the long trips I'm planning trough Europe.
Can I choose a smaller condencer or won't it work with the rest of the system? I would like to make room for an rx7 oil cooler below it.

There is a condenser that should be able to fit an RX7 cooler below it...I don't have an RX7 piece anymore to measure, can you check the width? Should be OK.

The RX7 cooler is 120mm tall. Perhaps you could offer that as an option for those interested in tracking their cars?
Come to think of it will probably be more expensive for me to ship the parts across the pond than it will be to fab up something over here. If not I'll get back to you.

Hi all,
I am posting this to gauge interest for the 944 owners who want to keep AC on their cars but have been forced to convert to R134a. The stock AC condenser is a fine unit but designed for R12 instead of R134a so doesn't work quite so efficiently. There is also the ~20-30 years of rocks and birds stuck in the fins on the outside, and dirt and slime on the inside reducing cooling efficiency.
A stock replacement for the AC condenser for a late car is $400, early is NLA. There is a made-to-fit serpentine style condenser available for the 944 but it runs around $500.
Modern cars with R134a from the factory use a parallel-flow type of condenser - rather than a tube-and-fin style the gas flows into the end tanks and makes several passes across the heat exchange surface before being expelled as a liquid. More distance to travel through the condenser means more time to cool, and the passages are designed with R134a in mind.
I have modified an aftermarket parallel flow condenser to bolt-up to a 944 using factory bracketry. It worked so well for my customer's 944S that I am offering this as a service to Rennlisters. Send me your factory condenser and I will send you back a bolt-on parallel-flow replacement - I need the factory piece for its bracketry. I am offering this at $325 including parts, my time, and return shipping. I can build one for you and you send me your old ones afterwards on an exchange basis as well.
It should be noted that 2 AC lines will need to be modified and re-made to make this work. The compressor to condenser line needs to be lengthened and a different fitting attached; and the condenser to dryer line needs a few more inches and a different fitting as well. About $375 total if you want me to make the lines for you as well, or I can give you dimensions to do yourself.
If you would be interested in this, let me know here or PM me.

You can actually just buy one ready to go. That's what I did...seems very high quality, though I don't have a car to install it into yet

That does look like a nice piece...the price is good too.
I don't have the time to do these anymore...so I defer to Griffiths.
I have had a parallel flow on my car since maybe 2009? And it works GREAT.

If you want something that will connect to your existing lines it will, by default, NOT be universal. Universal means it'll work if you can make it work, as in make up a new mounting system and your own lines & fittings. Definitely doable if you have or can borrow the required tools to do it.
