We've posted extensively about the AC line kits we've produced for the FD on Instagram and Facebook, but for those that are not on those platforms, hopefully this thread helps. These line kits include the following parts and allow you to run an RX8 AC compressor and condenser which are rated for R134. The RX8 parts are easily sourced from many places.

• CNC machined aluminum adaptor brackets to mount the RX8 compressor to OEM compressor mount on a 13B-REW engine
• Plug and play harness for RX8 compressor to OEM body harness connector
• Plug and play harness for binary pressure switch to OEM body harness connector
• Binary pressure switch
• R134a rated o-rings
• 30mL bottle of Nylog Blue o-ring lubricant/sealant
• Stainless steel hardware
• P-clamps and zip ties
• AC lines with high and low ports with caps located in the same location as OEM AC lines; lines wrapped with high temp sleeving on sections adjacent to turbo area (as applicable)

Our line kits replace all the OEM lines, dryer, binary switch sensor, and ports. The only OEM FD part required in the in-dash evaporator. We have the following iterations now available and will soon release the RHD SMIC/FMIC line set as well.

• LHD Greddy V Mount - MANA
• LHD Greddy V Mount - DENSO
• RHD Greddy V Mount - 92 and Earlier R12 Style Evaporator
• RHD Greddy V Mount - 93 and later R134 Style Evaporator
• LHD SMIC/FMIC - MANA
• LHD SMIC/FMIC - DENSO

We offer two types of bracket kits that will allow you to mount the RX8 condenser.

• Mazda RX7 FD3S Greddy Vmount Radiator AC Condenser Bracket Kit
• Mazda RX7 FD3S OEM Radiator AC Condenser Bracket Kit This is intended for those running OEM/OEM Style radiators in Stock, FMIC, and custom vmount configuration (if using the stock type radiator, see pics for details)

We do recommend removing the evaporator under the dash to clean it out (likely gunked up with debris, etc.) and to replace the expansion valve. We have all of the expansion valves posted in our store, and are packaged in a kit to include all of the service parts needed, including the expansion valve, enclosure foam, o-rings, and cork tape (as applicable). All replacement expansion valves are R134 rated.

• Mazda RX7 FD3S AC Expansion Valve Replacement Kit ***RHD JDM MANA***

In addition to the store product descriptions, we've compiled a series of videos on our YOUTUBE channel that explain the line kit iterations, evaporator removal, how to determine which style evaporator, etc.

 

We've got LHD and RHD linesets for guys running the HKS Vmount available as well.
