Increased Power We are often asked for engines with more power, more strength, and less maintenance at an affordable price. While these might seem to be mutually exclusive outcomes, we have had our heads down and been hard at work to meet the challenge! It’s taken a long time, but our patient research and development have resulted in multiple Cosworth based engine configurations with the strength to handle 250kw to 550 Kw. These packages range from options that that won’t break the bank, to complete competition race engines. Of course, if you don’t want one of our package deals, we can build a custom performance engine to your specifications; professionally assembled by highly trained ADS techs at our factory outlet at Peakhurst, NSW

Greater Durability Of course, not everyone wants racetrack performance from their Subaru, but many owners do work their cars pretty hard; the man on the land, the traveller, anyone who covers a lot of ground, will want a strong engine. Our remanufactured Cosworth assemblies are perfect for demanding applications. They can operate under extreme loads while maintaining consistent strong output. Precision Cosworth engineering, using high-grade metals and processes, delivers excellent wear qualities. A Cosworth engine will be operating efficiently long after stock engines have worn out. If you and your Subaru work hard, you’ll want a hard working engine. You can’t go past Cosworth.

Best Quality Very early on, we found that there are many performance parts suppliers and engine builders around the World who sell cheap, inferior products marketed as premium. It’s our philosophy to make sure that our products are truly the best available. In production too we aim to be the best. All Drive Subaroo don’t just put engines together like Lego blocks. We’ve carefully thought out all our setups, and spent hundreds of hours of building and testing to produce the optimum in performance potential and durability. Our Cosworth EJ20/25 Engine setups have gone through countless hours of dyno evaluation to determine the best combination of parts.

Service and Support All Drive Subaru have assembled the most highly skilled group of Subaru techs in the country, together with the finest facilities available outside the dealer network. Our crew have been trained in different specialist areas, and we know more about performance engines than the dealers, who bring any such jobs to us. We don’t just sell engines, we also offer technical support and assistance throughout the process and afterwards. Before you commit to an engine, we can talk you though all the available options. Once you’re back on the road, we are ready to assist with any questions you might have about the running and maintenance of your new engine. Everyone at ADS is an experienced technician or an auto engineer.

Exacting Production standards The Cosworth Subaru engine is designed for the demanding performance enthusiast. Each assembly is precision built by one of All Drive Subaroo’s specialist craftsmen using the finest components from our parts catalogue to ensure maximum reliability and performance. Starting with a new Subaru EJ257 semi closed deck block, we diamond hone each bore to guarantee perfect piston to cylinder wall clearance. The block is then assembled with Cosworth Forged Pistons, motorsport grade Forged H-Beam connecting rods along with Cosworth tri-metal bearings and a new STI forged crankshaft.
