In this part of the video, Trey Capsule from Elk Motorsports reviews components of his turbo kit. He highlights that most parts come with the kit, except specific ones like the intake manifold and oil pan. Trey then explains his custom-built intake system, created using locally sourced parts mainly from Autozone. He describes using a universal stubby air filter, carbon fiber plate, exhaust pipe, and silicone coupler. He emphasizes why he chose the KO3 turbo, commonly found in Volkswagen and Audi 1.8L turbo motors, for its suitability for low RPM range and good performance in the Suzuki Samurai.

In this part of the video, the speaker discusses the specifics of a turbo setup for a motor, emphasizing why an intercooler isn’t necessary due to the associated pressure loss. They break down the components of the turbo, such as the compressor side, turbine side, and cartridge area, which houses the inlets and outlets for oil and coolant. If not water-cooled, it’s recommended to idle the engine to allow hot oil to circulate out.
The speaker explains the oil feed and drain system, highlighting the proper fittings and lines used, such as the oil feed fitting, a 90-degree elbow, and a PTFE oil feed line. They also clarify the correct adapter for the oil pressure switch, distinguishing between NPT and BSP threads, and detail the necessity of an oil restrictor to prevent oil from forcing its way past the turbo seals and causing oil burn. They then outline the steps to connect the oil lines and mention plans to customize the hose length for a more ergonomic fit in future builds.

In this part of the video, the speaker discusses the importance of using at least a 10 AN fitting for the oil return on a turbo to prevent oil pressure build-up and seal blowout. The kit being used includes a 10 AN braided stainless steel hose, various fittings, and a piece of pipe. The speaker explains their preference for threading a fitting rather than welding it directly to avoid future damage and ease of replacement. Additionally, they mention the proper setup for water cooling a turbo, specifying the correct thread sizes. The segment finishes with a discussion on the design of an exhaust manifold, noting its thick flanges to handle heat, and clarifies that effective exhaust flow before the turbine is not as crucial for a turbo setup compared to a naturally aspirated one.
00:15:00
In this part of the video, the presenter explains the design and installation process for a turbo exhaust system, focusing on creating a path of least resistance for exhaust gases to improve turbine efficiency. They discuss the importance of a custom downpipe, noting that it typically requires a visit to a muffler shop for precise bends and reductions. The presenter also points out that the turbo kit includes an exhaust manifold gasket but lacks other necessary gaskets, so they recommend purchasing a separate gasket kit or using high-temperature gasket maker.
Additionally, the presenter covers the setup for the air intake side, detailing the use of charging pipes and silicone couplers to connect the turbo to the intake manifold. They describe creating a support bracket to prevent the pipes from rubbing against the radiator hose and note the inclusion of ports for boost reference and a blow-off valve. Finally, they mention that the turbo kit is compatible with existing side draft carburetors and may require additional components such as a hog ring for proper installation.

In this part of the video, the presenter explains the intricate assembly and functionality of a modified carburetor system. They detail the connections and adhesive gaskets necessary to secure the components, ensuring the carburetor and associated parts are sealed properly to manage air and fuel pressure. The presenter highlights the use of a boost-referenced fuel pressure regulator and the significance of maintaining pressure equilibrium within the float bowl to prevent fuel leakage. Furthermore, there’s an emphasis on the importance of preheating the intake manifold to ensure fuel stays atomized for efficient combustion, particularly in colder climates. The segment also covers transitioning from a mechanical to an electric fuel pump for consistent pressure, mentioning the necessity of proper mounting to reduce noise and the incorporation of a fuel pump relay for reliability.

In this part of the video, the speaker details the process of wiring a relay to power a pump. They explain how one wire powers both sections of the switch, which, when activated, energizes a relay to connect the main power source to the pump. The pump uses quick disconnect fittings for easy hose attachment to the fueling system. The fuel first goes to a fuel filter, through the pump, and into a boost-referenced fuel pressure regulator with a braided stainless steel line. The speaker describes modifying the fuel system, including adapting fittings, routing hoses, and adjusting the pressure regulator. Additionally, they discuss modifying an intake manifold gasket to fit their setup using a dremel tool. The fuel delivery system is tailored for a turbo application, ensuring proper fuel supply under varying pressure demands.

In this part of the video, the speaker discusses the benefits and limitations of modifying the intake manifold and turbocharging system. While port matching and polishing can enhance airflow and potentially add horsepower, such modifications might not be significant for a vehicle running a modest 6 PSI boost without an intercooler. For a small engine, like a 1.3 liter, the effort may not yield noticeable performance gains unless higher pressures and additional upgrades are involved. The speaker emphasizes practical considerations over minor enhancements.
Additionally, the speaker describes the installation and benefits of an oil catch can, highlighting its importance in handling excessive blow-by in older engines. They detail how they mounted a Mishimoto catch can, using a custom bracket and connecting it to the engine’s vent system to manage crankcase pressure efficiently. This installation provides a means to collect and drain excess oil and water, preventing it from entering the intake system.

In this segment of the video, the speaker explains the setup and mounting process for a boost reference fuel pressure regulator using a piece of wide aluminum bent at specific angles and mounted on the firewall. They highlight the use of an Astro 1442 tool, which allows for creating threaded holes in sheet metal and ensures cleaner installation. The speaker also reviews their turbo kit and encourages viewers to support the channel by purchasing ELF Motorsport logoed vinyl decals available in different sizes and colors. Additionally, they express gratitude to viewers, mention upcoming content, and encourage likes and subscriptions.
