ISR Performance – Top Mount Turbo Lines
ISR Performance offers a top mount turbo line kit designed to fit SR20DET engines commonly found in S13 chassis. The kit is built with quality materials and is designed to fit your vehicle according to manufacturer specifications for safe usage. This option emphasizes reliability and correct routing of oil and coolant lines to support turbochargers mounted in the typical SR20DET configuration. When selecting, verify compatibility with your specific GT series turbo and ensure proper thread diameters and hose fittings align with your engine bay setup.
Kinugawa Turbo Install Line Kit For S13 SR20DET
The Kinugawa Install Line Kit provides a comprehensive set of turbo oil and water lines compatible with SR20DET engines in S13 configurations. It is tailored for low-mount Garrett GT/GT-series turbos and clarifies compatibility with ball-bearing options. The kit notes that it cannot fit journal-bearing turbos without adjustments to the restrictor size, which is important for achieving proper oil flow and pressure. When evaluating, consider your turbo type, mounting position, and line routing to avoid interference with the intake and exhaust paths.
3 Bolt Turbo Adapter Kit For SR20DET
The Kuuleyn 3-Bolt Turbo Adapter Kit provides a robust flange adapter option for TT setups, specifically fitting Garrett GT25, GT28, T25, and T28 variants used with SR20DET engines. The product emphasizes high-quality materials, excellent durability, and resistance to impact and corrosion. It is positioned as a practical helper when upgrading or replacing outlet flanges in tight engine bays. Review your current turbo flange arrangement and verify bolt hole alignment before purchasing to ensure a clean fit and leak-free connection.
Turbo Outlet Adapter Kit For GT25/GT28/T25/T28 SR20DET
The Tbest Turbo Outlet Adapter Kit claims compatibility with GT25, GT28, T25, and T28 turbos for SR20DET vehicles. It emphasizes alignment with original factory specifications to ensure stable performance and reliable operation. The kit uses high-quality aluminum and focuses on resilience against impact and wear. Prospective buyers should confirm their exact turbo model and flange style to ensure the adapter matches the bolt pattern and gasket surface necessary for a secure seal.
Kinugawa Turbo Water Line Kit For SR20DET (Top Mount)
The Kinugawa water line kit is designed for SR20DET S14/S15 configurations with top-mount turbos, including TD05H/TD06 variations. It focuses on ensuring reliable coolant routing to maintain turbo efficiency and prevent heat-related performance losses. When selecting, check compatibility with your specific turbo model and whether additional fittings or reducers are required for your engine bay. Proper routing reduces the risk of coolant leaks and helps sustain steady boost during frequent RPM changes.
Buying Guide
- Engine compatibility: Verify the turbo model, mounting position (top mount vs bottom), and flange pattern to avoid fitment issues.
- Line quality and materials: Look for aluminum or stainless-steel lines with durable fittings to resist heat, pressure, and corrosion.
- Oil vs. water lines: Ensure the kit provides the correct combination of oil feed/return and water lines for your turbine and intercooler setup.
- Restrictor sizing and flow: Some ball-bearing turbos require different oil restrictors; confirm kit specifications with your turbo type.
- Ease of installation: Consider kits with clear diagrams and hardware that match your car’s existing bolt patterns and spacings.
- Warranty and support: Some brands offer longer warranties or online technical support—evaluate these factors for peace of mind.
- Future plans: If you plan to upgrade to a different turbo later, consider modular line kits that can adapt to new setups.
