Have you seen the price of Porsche 964 hardlines? Here's one:

Glad to see you are involved and responsive on Rennlist. I'm very interested in the kit but am hesitant due to the difficulty involved in replacing the evaporator - I've taken apart a suitcase before and it's a daunting task... the rest of the job seems like a reasonable DIY but getting a specialist involved to replace the evaporator probably doubles the cost of the project.

I'm sorry this isn't what you were hoping before but judging by the amount of emails we have had about this system, I think you are in the minority. In our view, there is nothing wrong with the original airbox and fans, they perform well. The blower final stage can fail and we will release a kit for that soon. I agree on your point about the CCU and servos and we have a development program for that but one step at a time. Nobody will be making a 'cheap' CCU - we have $80K development costs in ours already!
For a lot of people with non functional AC, the main issue is knowing which part is the culprit. Replacing ALL the lines with original Porsche parts is an expensive exercise (some lines are over $400). Our kit replaces everything in the refrigerant loop with new so you don't have any doubt about whether there is debris in the hoses or pinholes in the lines. Having all the kit up front means easier install and access.
The compressor on the engine is an eyesore for many.

The frustrating thing is the insanely expensive replacement parts ie, the servos, fans, and CCU are still required for your system.

In bold text on page 6 of the install instructions:
We do strongly recommend that the original blower unit is overhauled prior to installing the kit. All servo valves and flaps should be checked over and a new evaporator fitted –these are available from Porsche. Non AC cars use the same blower so an evaporator can be retrofitted.
They then repeat their guidance to fit a new evaporator on page 10.
I understand why they want you to fit a new evaporator - the new ones from Griffiths are apparently a better design, and you know the fins aren't clogged and there are no leaks... but it's another $600 part to add to the project and then all of the labor involved in the process. Then you really want the upgraded alternator to run the A/C compressor at idle, but to get full power out of it you need to do a serpentine belt conversion, etc etc... the whole thing is a slippery slope. Somehow you end up spending 7 or 8k on the project, which covers a whole lot of A/C recharges at $170 a pop.

Use the controls, evaporator, servos and single fan from a 2000+ GM or Ford pickup, package it in a box that will fit in the dash, and it would better and cost peanuts. Combine that with your electric compressor, And you have a winner!!

The CCU is a joke by modern standards, don’t redesign it, throw it away.

The guys at Driftworks have just installed one of our kits in their RWB Turbo - video below. Awesome car:

Do you guys have a lead time on your kits currently? I tried emailing some questions a couple months ago (including that one) but never heard back.

Lead times are on the website ( 3 to 4 weeks at present ). Apologies if your email was lost - it's a busy time of year for us - we have over 100 kits on order at the moment!

All good, I totally get that. The email was about the lead times, and I saw in one of your videos you mentioned the development of a heater kit. I was just curious where you're at with that as well (may need to also do electric heat)

For 964 RS that came with no AC at all, can I swap its CCU with another one from 964 that has AC and hence can it work plug & play with your system ?
Better yet, can I send you the CCU with AC to be configured and made sure functioning well as control unit of your AC system ?
