Custom AC System & More: Completing the RB25 240SX Restomod Build

Custom AC System Installation

• 💡 A custom air conditioning system was installed in the RB25-powered 240SX restomod, utilizing a mix of original Nissan, Skyline, and universal parts.
• 🛠️ Key components included a NOS Nissan RB25 AC compressor, custom fittings, and hoses from COLDHOSE.com, along with a universal condenser and electric fans from Mishimoto.
• ⚙️ The system is controlled by a Haltech ECM, and a 190-degree thermoswitch from SETRAB.com was used to activate the AC fans.
• ⚠️ The speaker emphasizes using '94 240SX R134a charging and oiling specs at the viewer's own risk, recommending professional charging if unfamiliar with AC work.

Exhaust and Lighting Upgrades

• 🔥 The hot side of the exhaust system and turbo were recoated by Jet Hot with their 2K series coating for improved durability and heat resistance, rated up to 2,000°F.
• ✨ An underglow and interior lighting kit from Oracle Lighting was installed, including underbody glow strips and interior dashboard lights, with custom brackets fabricated for bumper mounting.
• 💡 New Oracle Lighting LED headlights with halos were installed, noted for being significantly brighter than the factory halogen units and plug-and-play.

Interior and Glass Restoration

• 🚗 A local glass company, Pops Auto Glass, installed new seals and trim, including original 180SX quarter glass and a new windshield, to complete the car's cosmetic emulation.
• 🧩 The evaporator core and expansion valve inside the car were cleaned and resealed, with new O-rings and cork tape applied to ensure proper function.
• 🔊 The blower motor was also cleaned, resulting in quiet and efficient operation.

Electrical and Haltech Integration Challenges

• 🔌 Significant effort was dedicated to understanding and integrating the AC system's wiring with the car's original harness and the Haltech ECM.
• 🔍 Troubleshooting involved tracing circuits, verifying wiring diagrams from a 1989 240SX service manual, and consulting the Haltech Facebook group.
• 💡 The primary issue was identified as a cracked solder joint on the car's original thermal control amp, which was resoldered to restore communication and AC functionality.
• ✅ The custom AC system was successfully charged, with infrared thermometer readings showing vent temperatures around 37°F.

Final Touches and Build Overview

• 🌟 The completed restomod features an OEM+ aesthetic, utilizing many original Nissan parts alongside aftermarket components.
• 🎶 The interior includes the Haltech IC7 dashboard and an early 2000s Pioneer radio, with a modified CD9 six-speed transmission and an uncut center console.
