HI POWER 2F

Not your average 2F…

You don’t often hear the terms ‘high performance’ and ‘2F’ used together, but this is not your average 2F. Let’s be honest, the 2F is underwhelming in stock form. It really shines when used for its intended purpose - idling down the trail in low range, the impressive torque pulls these heavy machines with ease. Back in daily life, however, it struggles to keep up with modern vehicles.

Merging on the interstate, passing slow cars, steep hills… these are no longer actions to dread in your cruiser, now you can look forward to them.

Take a look at this race between one of our Hi Power 2Fs and a well-tuned stock spec 2F. Both FJ40s had the same tires and gear ratios, and were otherwise similarly equipped. The difference is astounding.

The video is backed up by the dyno. Here is a comparison with well-tuned stock FJ60:

Let’s face it, no matter how you slice it, rebuilding a 2F is not easy on the wallet. To keep costs down, many engine rebuilders use aftermarket parts sourced from China and Taiwan, or use “forklift” rebuild kits of unknown origin. While this will get them out of the warranty period, these parts are not manufactured with the same quality or consistency as factory Toyota and high quality Japanese or US-made aftermarket parts.

On a typical rebuild, we start with a ‘81 and newer 2F, which uses flat pistons and a closed chamber head. We use the largest Toyota pistons we can get our hands on and bore & hone the block to fit. We can also build ‘75-’80 2Fs using TLC Performance’s high quality USA made Wiseco forged 1.5mm oversized dome pistons. (The OEM dome pistons have been long discontinued, with Taiwanese pistons being the only other option.) The crank is turned & balanced and the camshaft is reground for an improved power band. New Toyota timing gears are installed on the crankshaft and camshaft. Pistons and rods are weight-balanced to the lightest rod for smooth operation. The bottom end is then reassembled with high quality US made rings and Japanese bearings.

The front of the crank receives a new or remanufactured harmonic balancer and a resurfaced and balanced flywheel, both essential to smooth power.

The head is where the magic happens. The Toyota valves are replaced with modern domestic valves which are lighter and larger diameter, and utilize modern progressive springs and modern stem seals. These valves breathe easier and last longer than the stock valves. Once the valves are installed, the heads are CC’d for volume and milled to a precise, calculated 9.0:1 compression ratio.

We top the head off with a completely rebuilt rocker assembly. The shaft is hard chromed and turned, and the rocker arms are rebuilt, resurfaced, and honed to fit the rebuilt shaft.

These motors look as beautiful as they run. The block and head receive several layers of premium high temperature paint, while the engine covers are media-blasted and powder coated before assembly with new, stainless metric hardware. We personally hand-assemble each motor to assure it meets our standards.

After assembly, each motor is run on our test stand to break in the cam, check for leaks, and verify that it is ready to leave our facility.

We recommend upgrading to fuel injection to maximize performance, drivability, and engine life. If a carburetor is desired or required for smog, we are happy to recommend a competent rebuilder.

We prefer to build your motor, but do often have cores available to be built on an exchange basis. We are happy to arrange freight shipping.

Additional services are reasonable and available a la carte. We are happy to blast & powdercoat accessory brackets and bell housings, as well as supply new or rebuilt accessories and fuel injection system.

High Performance 2F builds start around $13,000.

If you are interested in a Super HiPo 2F, we have a few more tricks up our sleeve that require custom pistons and rods. This adds considerable expense, but saves over a pound per cylinder of rotating and reciprocating mass. This is a good option for those considering an engine transplant, but want to keep a 2F under the hood for original looks.

As of February 2026, we have a considerable wait list for 2Fs and are experiencing long lead times with our machine shops. We are accepting very few new build orders at this time with an expected completion time later in the 2026 calendar year.
