Subaru Engine Replacement Options

Repair, Rebuild or Replace? How do I choose?

In today’s automotive engine industry there are many terms used to describe Subaru engine repair techniques and consumers are often unsure about exactly what they are getting. Terms like “repaired”, “overhauled” or “reconditioned” or “re-manufactured” can be misleading because they mean different things in different workshops and there is no governing body to set and maintain standards. Sometimes this means consumers are worse off than before, because they might have purchased something that either exceeded their needs, or failed to meet them. Consumers have differing needs, in terms of application and budget. They might need a repair for an older car that won’t exceed the value of the car, or they may want a high quality replacement engine for a late model vehicle that will give long life and high reliability.

At All Drive Subaroo we have worked over many years and invested heavily in designing clearly defined levels of engine construction for differing purposes and budgets. Our different engine builds cater for all consumers, from those who need to keep an older car going inexpensively, to motorsport enthusiasts who need an engine strong enough to develop high power with high reliability.

Apart from the confusion in the industry as to engine construction methods, consumers have to also be mindful of the different engine configurations. Engines are marketed in four configurations: short block, long bare engine, long dressed engine, and fully assembled crate engine. Which one is best for you will depend on the mileage of your vehicle, and on the condition of the cylinder heads and peripheral components such as the turbo, the coolant and air hoses, and the water pump.

The complexity of choice has been made worse by the evolution of Subaru engines into different types for different applications, as well as incremental changes to adjust for new laws and standards,. Subaru engines have developed into several types and capacities, in part to meet consumer demand for style and performance, but mainly for fuel efficiency and emissions control. Subaru face challenges ranging from designing efficient normally aspirated four and six cylinder engines to high performance turbo charged models. Subaru have also worked hard to compete with engine designs from other manufacturers, in terms of servicing and general running costs.

Engine purchase cost is another factor that makes choice more difficult. Australian prices are high, compared with Europe and and North American prices, and it is tempting to buy an imported engine for considerably less money than one that has been built in Australia. However, there are traps and complexities when considering imported engines. Subaru engines are designed to meet specific local requirements and an engine designed for the European or US market is not likely to be interchangeable with an Australian complied vehicle. Consumers have often been caught out with a bad investment in an engine they are unable to use in an Australian complied vehicle.

Short or long, bare or dressed

As if sifting though the different engine types to find the right one for your car wasn’t confusing enough, you also have to decide just how much of your old engine you need to replace. Do you just need a new block, crank and pistons? Or do you also need cylinder heads? What can you re-use from your old engine assembly, and what should be replaced? Some items it is good practice to replace as a matter or routine; things like coolant hoses, timing belt, water pump. Other more expensive components, such as cylinder heads, will depend on the mileage of your vehicle, and the condition of the components. All Drive Subaroo have expert consultants standing by to help you make the right choice. See below for details of each choice.

Engine construction methods

Guaranteed rebuilt, reconditioned or remanufactured engines – peace of mind

The final decision to be made is between a used engine, or one of several restoration options. At ADS we offer four levels of engine replacement, rebuilt, reconditioned, remanufactured, and for turbo models, Cosworth. Level 1 is a “repaired” or “rebuilt” engine that has been dismantled, inspected, cleaned and reassembled with new and serviced components and comes with a basic warranty. Level 2 is a “reconditioned” engine that has undergone a process of replacing and refurbishing to precise high quality Subaru specified standards. Level 3 is our “remanufactured” engine, which represents the highest level of Subaru engine restoration. Remanufacturing produces by far the most durable engine, and incorporates all the latest revisions to address inherent weaknesses. At ADS we also offer a fourth level available only for turbo models, an engine that has been remanufactured using Cosworth performance components. The warranty terms vary with each method.

The Many Engine Modes of Subaru

The Many Engine Modes of Subaru

Subaru are an innovative research and development oriented company, and their range of engines has evolved rapidly in response to consumer demand, competition initiatives, and changing emissions and fuel consumption requirements. Engines must also vary for different applications; low revving high torque engines for load carrying ability, and high revving high output engines for motorsport application. Cars like the Forester and Outback tend to have lower revving high-torque undersquare engines for cruising and pulling loads, while the WRX and STI models have high revving over square engines designed to produce power at the high rev ranges. See below for the full range of Subaru engine types.
