Frequently Asked Questions:
Q: What is included in this kit? This kit includes 6AN coolant lines, 4AN oil feed lines, 10AN oil drain lines, a vacuum/boost block, and additional AN fittings for turbo and block connections on twin turbo LS builds.
Q: Is this kit specific to a certain turbo brand or size? No. This is a universal kit designed to work with most twin turbo LS applications. Verify your specific build requirements before ordering as some custom setups may require additional components.
Q: What AN line sizes are included? 6AN for coolant lines, 4AN for oil feed lines, and 10AN for oil drain lines — the standard sizing for most turbocharger oil and coolant connections.
Q: What is the vacuum/boost block used for? The vacuum/boost block provides a centralized distribution point for vacuum and boost reference lines, simplifying routing in turbo builds with multiple boost-referenced components such as wastegates, blow-off valves, and boost controllers.
Q: Will this kit work with a single turbo setup? This kit is designed for twin turbo applications. Some components may be usable in a single turbo build but the kit quantities and configuration are intended for twin turbo use.
