Which Trucks Came With the 2TR

The 2TR-FE was the four-cylinder in the second-generation Tacoma (2005-2015), the third-generation Tacoma (2016-2023) and the fourth-generation 4Runner. Toyota revised it along the way — later engines gained dual VVT-i — but the block, the bore spacing and most of the hard parts carried through the whole run.

Written 2TR, 2TRFE or 2TR-FE, and often just called the 2.7. All the same engine.

Boost It — The Supercharger

This is the reason most people arrive here. The 2TR 2.7L Tacoma supercharger kit is a complete system, and there is very little else available for this engine from anyone.

Worth setting expectations honestly, because the 2.7 Tacoma is a truck people buy for reasons other than speed. A blower on a 2TR will not make it a fast truck. What it does is give it the mid-range it always lacked — merging, towing, climbing a grade without dropping two gears. That is a real improvement in how the truck drives every day, and it is the right reason to fit one.

If you are chasing outright power on a 2.7 four-cylinder, the honest answer is that the money goes further elsewhere.

Bolt-On Power

The Power Package for the 2005-2015 Tacoma bundles the naturally aspirated bolt-ons that work together rather than fighting each other — the usual starting point before anyone considers boost.

Individually: the 2TR Tacoma long tube header kit for 2005-2023 is the single biggest naturally aspirated gain on this engine, and the 2TR runner kit addresses the intake side. Fit the header stud set and the street header gasket set at the same time — the factory hardware is not worth reusing on a header install.

Build It — Valvetrain and Internals

The Pro Valve Train Kit for the 2TR-FE is the foundation for any build that adds boost or revs, and the Inconel exhaust valve is the answer where heat is the problem — forced induction, sustained towing, or a truck that lives at altitude.

For the bottom end, street pistons with rings in standard bore.

The Balance Shafts

Like the 3RZ before it, the 2TR runs balance shafts, and they carry the same trade-off. They cost a little power and oil pressure to drive, and their bearings are a known wear item on high-mileage engines.

The balance shaft removal kit deletes them properly. If you are keeping them, the balance shaft bearings are available on their own.

Our view: on a stock daily-driven Tacoma, leave them alone. The engine is smoother with them and you will notice their absence at motorway speed far more than you will notice the power. On a built or boosted truck, delete them.

Maintain It

The water pump covers 1995-2023 across the RZ and TR families, and the OEM flywheel bolt kit is the sort of thing you only discover you need with the gearbox already out.

Related Engines

The 3RZ-FE is this engine's direct predecessor and shares the balance shaft design and several parts. The 2RZ-FE 2.4L is the smaller engine from that same era.
