ADS – Supplying Subaru Engines Australia Wide Since 1991

ADS have specialized in re-manufacturing Subaru engines and gearboxes for over 25 years. In that time, we’ve established our own re-manufacturing techniques and revisions to counter factory inherent weaknesses associated with each particular Subaru model.

Three levels of re-manufactured engines to meet your performance need

ADS have developed three stages of re manufactured engines to assist you in choosing the right engine for your Subaru. We can supply budget rebuilt engines for a quick economical solution, fully re manufactured engines for long term strength and reliability, and high power Cosworth performance engines for the committed weekend racer.

High performance Turbo engine options

For turbo models there are more options, using Cosworth components. Cosworth engines are built to take it. If you’re going to work your Subaru hard, under heavy loads, in extreme environments, or at higher boost, the Cosworth equipped Subaru engine is a good choice for you. An ADS/Cosworth engine is durable and strong straight out of the box, and provides a platform for higher power outputs if required. Just how much power you might make with your Cosworth engine depends on a number of factors, including ECU, fuel delivery systems, intercooler and exhaust configurations. Package deals are available to produce up to 300 KW at the wheels.

    Hi ADS guys! Thanks for getting me back on the road so fast. I’ve had this car for three years, and it’s never gone as well as it does now–can’t hear it running in traffic, and it just eats hills. Getting your reconditioned 2.5 liter engine was the best decision...
