1HZ Engine Rebuild Kit. Late model 1HZ engines from 01/1998-on

This is a Special Order item - please contact us to order your kit after you have read and understood the below information.

These basic engine rebuild kits are typically supplied as a custom order request made up to suit the specific requirements of our client's request for parts.

Additional parts are recommended (see below) and are purchased separately from the basic engine kit.

The process begins with tearing down your engine and measuring each of the tolerances to determine what specific over and under sizes are required for items such as the engine bearings, pistons & rings, and any other parts. All parts that are at or very close to their specified wear limits should be replaced.

Once you have your list, contact us and we will either order a kit in for you, or if we have the parts in stock put a kit together for you.

Notes about building a reliable or higher performance 1HZ:

If you are considering building a high boost turbo charged 1HZ, there are measures that can be taken to improve reliability with the increased power output, and many of these same considerations apply to a regular rebuild of any engine.

Measuring head bolt pocket depth and stack height

Upgrading to ARP head studs in place of standard head bolts (11mm vs 1/2" UNC)

Proper torque of the cylinder head bolts or studs (Ultra-Torque lube)

Block and cylinder head finishing specs (RA)

Shimming the block if "too much" has to come off the deck or head

Upgrading pistons and connecting rods

Cooling system demands - fan clutch and radiator

Servicing the injection pump and injectors
