Pro Valve Train Kit 2TR-FE

Pro Valve Train Kit | Toyota 2TR-FE (0-20 lbs Boost)

LC Engineering has eliminated the guesswork for your Toyota 2TR-FE top-end build with the Pro Valve Train Kit. This comprehensive package provides a perfectly matched set of high-performance components designed to support increased RPMs and boost pressures up to 20 lbs. Whether you are building a high-output naturally aspirated engine or a turbocharged street/strip set up, this kit delivers the stability and heat resistance required for professional-grade performance.

Enhanced Flow & Inconel Heat Resistance

This kit utilizes specialized materials to manage the increased thermal loads of boosted applications.

• Intake Valves: Manufactured from 21-4N high-grade stainless steel (stock size) with a black Nitride anti-friction coating. This promotes superior airflow and minimizes resistance within the valve guide.
• Exhaust Valves: Upgraded to +1mm oversized inconel. These high-nickel alloy valves are extremely heat resistant and 10% lighter than stock, allowing for more aggressive spark timing and improved valve-train stability.

-Note: Requires a performance valve job. Bowl and chamber porting is highly recommended for oversized valves.

Pro Dual Valve Springs & Seats

An essential upgrade for those running higher lift camshafts and increased RPM ranges. The dual-spring design ensures superior harmonics and prevents valve float.

• Seat Pressure: 65 lbs @ 1.430" installed height.
• Versatility: Optimized for both NA and boosted applications up to 20 lbs.
• Precision Seats: Includes custom spring seats that allow these dual springs to be installed without modifying cylinder head.

Titanium Retainers & Viton Seals

• Titanium Retainers: Proudly American made from space-age materials. These are less than half the weight of factory steel retainers but ten times stronger. They provide the confidence needed to rev over 8,000 RPM without the risk of splitting a retainer.
• Viton Valve Seals: Providing heat resistance up to 440°F (226°C), these seals outlast OEM rubber and provide a superior oil barrier, significantly reducing oil consumption through the valve guides.

Technical Specifications

• Spring Rate: 13.50 lbs/mm
• Max lift: 13.80mm (.540")
• Coil Bind: 21.80mm (858")
• Open Pressure: 185 lbs @ .400" lift

Kit Includes

• (8) Nitride Coated Intake Valves (Stock Size)
• (8) +1mm Inconel Exhaust Valves
• (16) Pro Dual Valve Springs
• (16) Precision Spring Seats
• (16) Lightweight Titanium Retainers
• (16) High-Temp Viton Valve Seals

-Tech Tip: The "Pro" kit is the ideal choice for 2TR owners looking to future-proof their cylinder head. By using Inconel exhaust valves, you gain a massive safety margin against the hight EGTs (Exhaust Gas Temperatures) common in turbocharged Toyotas.
