maXpeedingrods T04E T3 T4 Turbo Kit
The maXpeedingrods kit targets 4-6 cylinder engines, offering a 3″ inlet and 2″ outlet with a 1/8 NPT oil inlet. The compressor wheel is .55 trim with A/Rs of .50 (compressor) and .63 (turbine). This hybrid T3/T4 setup is designed for power handling in the mid-range range, with a suggested output window of 25-35 psi. Choose this kit if you want a ready-to-run turbo solution for a versatile K-series or other 4/6 cylinder builds, especially when planning aggressive daily driving or weekend boost. Best for builders seeking a compact, flexible turbo upgrade without sourcing separate components.
Who this is best for: enthusiasts building a 4- to 6-cylinder K-series-based turbo project who want a complete turbocharger in one package. Limitation: installation may require compatible exhaust manifolds and adapters specific to the engine bay layout.
AmiliParts Timing Chain Tensioner Oil Return Plate Cover
The AmiliParts kit is designed for Honda Acura K-series engines (K20/K24 family) and supports adding an oil return line or drain without drilling or welding. It aims for a perfect fit with a durable, anti-corrosion build suitable for high-temperature turbo installations. Best for K20/K24 builds needing an easy, non-invasive oil drain solution. Limitations: installation assumes compatibility with the listed engine models; verify clearance around the timing area in your chassis.
PQY Upper Coolant Housing With Integrated Filler Neck
Designed to fit K20Z3 and K24 heads while avoiding K24A1, K24Z, and K24Y fits issues, this housing improves clearance for sidewinder turbo manifolds. It offers a pivoting hose outlet to adjust angles by about 15 degrees, easing routing of upper radiator hoses. Best for builds needing radiator hose clearance, especially when installing compact or offset turbo manifolds. Caution: verify exact fitment for your exact K-series head version before purchase.
BXNTTCSFY K20 Turbo Exhaust Manifold
Material and design focus on high-temperature resilience and long-term durability in turbocharged setups. The manifold aims to optimize intake flow and combustion efficiency by aligning pipe lengths and diameters to reduce intake resistance and increase airflow velocity. Best for K20 turbo builds seeking a more efficient exhaust path. Limitation: real-world gains depend on the rest of the exhaust and turbo selection; verify compatibility with your turbo flange pattern.
REMTUNE K-Series Welded Turbo Oil Pan
This REMTUNE oil pan is built as a direct replacement for K-series engines and features a -10AN fitting for turbo oil lines, aligning with typical K-series turbo setups. Best for builds needing a robust, welded oil pan solution that accommodates turbo drain lines. Choose this if you want a clean, high-capacity oil return path. Caution: ensure compatibility with your specific K-series model and oil pump arrangement.
REMTUNE Aluminum K Series Turbo Oil Pan
Another REMTUNE option, this aluminum K-series oil pan is designed for turbo builds and includes a -10AN welded fitting. It aligns well with direct oil feed and drain components in K20Z3-based projects. Best for lightweight, performance-focused builds that prioritize efficiency and ease of installation. Limitation: compatibility varies by engine generation; confirm the exact K-series model before purchasing.
K20-SWT3-11G Equal Length Turbp Manifold
Equal-length manifolds can improve spool timing and flow consistency on K-series turbo builds. The K20-SWT3-11G is designed for Honda Civic RSX K20 applications. Best for tuners aiming for balanced exhaust pulses and a smoother power curve. Limitation: installation may require compatible turbo mounting hardware and flange alignment with your chosen turbo kit.
KINUGAWA Turbo Oil Return Line Kit
Kinugawa oil return line kit provides a dedicated oil drain path for KKK K03, K04 turbos and similar setups. It includes 50cm length and 8AN fittings, designed to match common K-series turbo drain requirements. Best for ensuring a reliable oil drain without custom fabrication. Caution: verify hose length and AN sizing with your turbo and engine bay layout to avoid routing conflicts.
Buying Guide: Key Purchase Considerations
- Turbo compatibility: Confirm engine family (K20, K24) and whether the manifold or turbo kit matches your head type and flange pattern.
- Oil routing: Assess oil feed and drain options to prevent oil starvation or leaks in high-boost setups. Look for -10AN (or similar) fittings when selecting oil pans or drain lines.
- Clearance and fitment: Check radiator hoses, turbo placement, and exhaust manifold clearance to avoid clearance issues in tight engine bays.
- Material and durability: Prioritize heat-resistant materials for manifolds and housings, especially in high-heat turbo environments.
- Installation scope: Some items are direct replacements; others require additional fabrication or adapter kits. Plan for hoses, clamps, and gaskets as needed.
FAQs
- Q: Which item is best for a bone-stock K-series engine planning a turbo upgrade? A: Start with a complete turbo kit that includes a compatible turbo, exhaust manifold, and oil drain options to minimize compatibility issues.
- Q: Do I need a special oil pan for turbo setups? A: Yes, a dedicated turbo oil pan with proper drain fittings helps ensure reliable oil return in boosted builds.
- Q: Can I reuse factory hoses with a turbo kit? A: It depends on routing; some kits require upgraded hoses and fittings for proper alignment and clearance.
- Q: Is an equal-length manifold necessary for street use? A: It improves exhaust pulse control and can aid spool, but may be less critical for casual street driving than for high-performance builds.
- Q: Are these parts interchangeable across all K-series engines? A: Not universally; confirm exact model, year, and head type before purchasing any part for your K-series engine.
