HalfSpec's 2014 FD AC Group Buy
« on: March 20, 2014, 09:55:40 AM »
Welcome to my 2014 FD AC Group Buy.

It's Getting HOT


Time to COOL THINGS OFF


This is the follow-up to a successfully group buy from last year.  As with last year, I’ll try and keep this brief, however, it is very important that you read and understand this entire post before you jump on board.  I’m in the process of getting my pictures updated so please bear with the pics from last year while I get everything straight over the next couple of days.


Offerings:

Note - The lines in the images above are shown with the $30 fire sleeve option

*LS1 Samberg R134a AC Lines = $400 USA shipped or $425 shipped to Canada. This is ONLY for people running Samberg radiator and suggested condenser.

*LS1 Custom R134a AC Lines = $440 USA Shipped or $465 shipped to Canada. This is for every other configuration. The reason for the price difference is because these lines take 3X+ the time it takes to build the Samberg lines because of the custom sizing and the back and forth we’ll have to do via PMs. Eventually, I will be able to lower the price on certain configurations (I.E., people running a hinson radiator), but as of now I have no set templates for any other configuration except for the Samberg config.

**LS2/LS3 R134A AC Lines Samberg/Custom. LS1 line prices above + $20. The extra $20 is due to the pricey custom compressor block. This option is for LS3 compressors that came off of SS Camaro's and possibly some LS2 compressors. Please PM me for more information.

Fire Sleeve = $30. This is an option to add fire sleeve to the line runs going past the manifolds / headers. It is not required, but it’s a nice addition.

LS1 Wiring / Control kit with purchase of lines = $90 shipped USA or $95 shipped to Canada. If purchasing separately the price = $110/$115 shipped USA/Canada. This is a kit that interfaces the RX7’s A/C button with the LS1 PCM. It also provides the wiring to the A/C compressor and pressure sensor. The advantage of using this kit is that when the PCM receives A/C requests from the RX7 A/C button it will safely control the compressor. Features enabled with this kit include:
a.   Completely plug-and-play. No splicing required
b.   Stock RX7 A/C button activation
c.   Compressor over-rev at high RPM protection
d.   Idle compensation
e.   Refrigerant low-pressure protection
f.   Radiator/Condenser fan control (as long as your fans are PCM controlled)



LS2/LS3/Universal Engine wiring / control kit rev 2 with purchase of lines = $135.00 shipped USA or $140 shipped to Canada. If purchasing separately the price = $155/$160 shipped USA/Canada. Prices shown are for control of LS1 and Camaro SS LS3 compressors. If you are planning to using a CTSV LS3 or other compressor I may have to tack up to an extra $15 (depending on your compressor) because of the a potentially pricy compressor connector. This is pretty much the same idea as the LS1 kit above, but this is a standalone system, which theoretically should work for ANY engine. The reason for this kit is because the LS2/LS3 engine requires that the Body Control Module (BCM) be attached to the PCM to relay control to the A/C compressor. Because no LS2 swap I’ve ever seen swaps over the BCM for this purpose, it is impossible to use the LS2/LS3 PCM to control the A/C compressor. Because of this, it is a requirement that the A/C system be controlled with a standalone system. Features enabled with my kit include:
a.   1 wire install (RPM wire splice), otherwise it's as plug-and-play as the LS1 kit above
b.   Stock RX7 A/C button activation.
c.   Compressor over-rev RPM protection.
d.   Refrigerant low-pressure protection.
e.   Radiator/Condenser fan control with sophisticated diode network to keep the CELs aways and your MIL light off(this will require 1 more wire splice and the car must use GM based relay wiring). Please see important note about this feature here
f.     Compressor under-rev RPM protection


* All lines will come with the following:
1. Plug and Play custom A/C Lines with all the proper fittings, service ports, compressor block, and all new seals.
2. Drier with mounting hardware
3. Instructions and part documentation including drier re-order information as well as o-ring sizes. I want you guys to be able to have full support for years to come even if I drop off the face of the planet (no plans to do that).

What do you need to go with this line kit to have working A/C?
1.   You will need one of the following manifolds/headers:
a.   JTR Longtubes
b.   Spoolin Headers
c.   Hooker 8501HKR cast manifold
d.   Hinson Longtubes (*Note* This is a tight fit and will most likely require that you loosen the passenger side header to wiggle the line fittings into place)
e.   LS3 manifolds (heatshielding may require notching)
f.   2000-2002 LS1 manifolds (heatshielding may require notching)
g.   98-99 LS1 manifolds (EGR casting ridge will need to be ground down (see this post))
2.   A condenser. Samberg recommends this one with his radiator. For people running other radiators, please PM me about it and I’ll make a recommendation.
3.   A LS1, LS2, or LS3 compressor mounted low on passenger side of engine.
4.   A Nippon Denso or Mana evaporator (identification tips below)
5.   For LS1 guys, you’ll need a GM pressure sensor (GM # 22664328 or AC Delco # 15-5742). For LS2/LS3 guys, see the electronics kit options below and you’ll need this pressure sensor:
6.   Supporting electronics / wiring. People that have had their wiring done by Pez will most likely have this already built in. If you had your LS1 harness modded for AC and it’s got 2 external AC related relays that were added to the wiring, chances are you’re all set.  If you don’t have your wiring done I offer LS1 and LS2 wiring/control kits that will allow the system to be integrated to the stock AC button.
7.   A way to oil and charge the system with refrigerant. This can either be DIY with PAG 150 oil, ~24oz of R134a, a vacuum  pump, and a set of AC manifold gauges, or you can take it to an A/C shop to have them do it.

Final questions for joining the group buy (I'll need all of these questions answered before I can accept any money or start building your lines):
1.   What style evaporator is on your FD? I.E., Mana or Nippon Denso? Option 1 - Here is a thread showing how to identify which evaporator you have. Option 2 – You can try and find test nuts locally which will easily help you determine which evaporator you have (M16x1.5 nut fits the small port on a Mana evaporator, 9/16"-18 nut fits the small port on a Denso evaporator). Option 3 - You can purchase test nuts from me for $5 shipped in the USA or $10 shipped to Canada.
2.   What type of condenser do you have? If you’re using a condenser other than the Samberg recommended condenser, It will be very beneficial for me if you have as much info as possible on your condenser if you want to use it though. Specifically what the port sizes are and how accessible they are using pictures.
3.   What type of A/C compressor do you have? I.E., LS1, LS2, LS3 etc
4.   What header / manifold are you using?
5.   Do you need any extras? I.E., wiring kit, heat sleeving, etc?
6.   What radiator are you using?
7.   If ordering a wiring kit, where is your PCM located?

If you’re interested in joining this GB, please post your name in a list and PM me the answers to the questions I listed in the section above labeled “Final questions for joining the group buy”

I am planning on running this group buy for a month with the possibility of an extension depending on interest. Orders will be shipped based on completion of the information I need to build the lines, NOT in the order you signed up. In other words that means YOU will be responsible for how fast your lines ship. If you get all the info I need to me on the first day, your lines will ship first. If you drag your feet and wait a month before you get me the info I need, your lines will ship last.

Thank you for your interest and please let me know if you have any questions:

Unfortunately y'all are behind the FC guys in line  :'(

For the FC guys, the evaporator options and fittings are unknown to me. For 2JZ/1JZ guys, I have no sources for adapters to connect to Toyota compressors. For both parties, no two FCs or 2JZ FDs are built the same, making each and every job a custom one and therefore not cost effective.

It's possible I'll support more cars in the future, but I'll have to figure out how to make it cost effective.

I might have FC A/C parts I can send you.   I wish I could fit a compressor on my car, but given A/C vs. dry sump, dry sump's a-gonna win.

Blake. Thanks for the offer. I may take you up on that one day.

I'll go ahead and address the FC situation since I usually get hit up about it ~10 times over a season.

Here's what's holding the FC AC conversion back.

1. For me to be interested, I need 3 fairly stable points in the FC's engine bay. They've got 2 pretty stable points so far. The evaporator and the compressor. What I'd need next is a very universal place to mount the drier that  would work for most LS FC guys. If we could figure that out it would cut the number of custom lines in half as 2 lines would always be the same. From that point I'd only have to custom make the lines leading to the condenser (2 lines). Even custom making 2 lines can be a major undertaking. Last year I had 56 outgoing PMs between a single user (it was ~112 messages total). getting measurements for a FD using a Fluidine radiator and custom condenser. Now, on average it doesn't take 112 PMs and in fact I've refined the process quite a bit by introducing the concept of sending "fitting kits" to allow the end user to create quickish mock ups without requiring a lot of help from me, but it's still time consuming, expensive, and its not something they can just order and have me pop it in the mail the next day. Currently, the only set of lines I
can do that with is for the folks that use a samberg radiator and recommended condenser because that gives me 4 stable known points to build lines between giving me to ability to work from a template.

2. Evaporator fittings. I've heard that the FC uses as many as 3 different evaporators. To be able to offer FC AC I'd have to know the specs on all 3.

3. Electrical control. I have no idea where to even start with this one as I doubt the FC's HVAC control panel works exactly like the FD. I could make an attempt with HVAC diagrams, specifically the AC button, but it would be a crap shoot to get it to work. The FD's FSM is absolutely non-representative of how the circuit actually  behaves and I can only assume the FSM writing people weren't making advances in their documentation in reverse ;)

4. Demand. Sorry guys cause this just sounds mean, but its something I have to consider when devoting my extra time to a project like this.

5. Pending the other 4 points I'd have to have a partner that's very good at documenting, takes good pictures, and has a FC that's pretty middle-of-the-road to work with to develop a partial blueprint for the FCs layout.

All-in-all its going to be hard for me to expand this service to other cars without an example sitting in my garage because its exponentially complicates things to do it over the internet/phone.
