AK series


Lachute Performance offers robust, reliable and efficient forged engines, adapted to your needs and your budget.

The AK-1
Equipped with forged pistons, the AK-1 is perfect for increasing the reliability rating of your everyday car, or for replacing a present engine that has failed.

Here are the components that distinguish the AK-1 engine from the original Subaru engine:

Forged Pistons
The forged pistons, thanks to their reinforced alloys and their design, offer greater reliability compared to the stock pistons. We offer two choices of forged pistons for the assembly of your AK-1 in order to offer you the solution which will be the most adapted to your use and your budget.

Crankshaft bearings
The quality and strength of the bearings are essential to the proper functioning and longevity of your engine.

Engine block
We carefully select, measure and engineer our engine blocks to our own specifications to provide high precision assembly.

The AK-2
Ideal for your everyday car, or for sportier use. The AK-2 engine offers added reliability over the AK-1 with the addition of forged connecting rods to the forged pistons. You find the AK-2 mechanics in the LP400.

Forged connecting rods
Forged connecting rods, thanks to their reinforced alloys and their design, offer greater resistance to deformation during high engine revolutions and provide additional reliability compared to the original connecting rods.

Crankshaft bearings
The quality and strength of the bearings are essential to the proper functioning and longevity of your engine.

Engine block
We carefully select, measure and engineer our engine blocks to our own specifications to provide high precision assembly.

The AK-3
In addition to the forged pistons and connecting rods, a forged / balanced crankshaft takes place at the heart of the engine. The AK-3 is custom designed according to your needs for your race car or a high performance project. You will find the AK-3 mechanics in the LP400Rs. Here are the components that distinguish the AK-3 engine from the original Subaru engine:

Forged Pistons
The forged pistons, thanks to their reinforced alloys and their design, offer greater reliability compared to the stock pistons. We offer two choices of forged pistons for the assembly of your AK-3 in order to offer you the solution which will be the most adapted to your use and your budget.

Forged connecting rods
Forged connecting rods, thanks to their reinforced alloys and their design, offer greater resistance to deformation during high engine revolutions and provide additional reliability compared to the original connecting rods.

Lightened crankshaft
The lightened crankshaft offers better response and dynamism to the engine thanks to its lighter mass.
