Prior to launching the 1990 Legacy, Subaru drew attention to the car’s capabilities and durability by attempting to set world speed records with the Legacy. In an effort involving three Legacy RS Turbo Sedans, Subaru established a new 100,000 kilometer (62,137 miles) world speed record as well as 13 international records. Some of these records still stand today.
For the 1990 model year, Subaru was launching the Legacy, a front-wheel drive model with optional 4-wheel drive. It was larger than previous Subaru models and had a 2.0-liter, 16-valve, turbocharged engine. Since the car represented a new segment for Fuji Heavy Industries Ltd. (FHI), it wanted to demonstrate the vehicle’s performance, reliability, and durability. Thus began the quest for the 100,000 kilometer (62,137 miles) world record. That represents the distance typically covered during five years of hard driving.
It is not necessary to perform a cool down/idling procedure on Subaru WRX turbo models, as was recommended with past turbo models. “The current 2.0 liter turbo engine has a far greater cooling capacity and, coupled with technology advances, makes this practice no longer necessary. This explains why information about a cool down is not included in the Impreza Owner’s Manual.
The heat contained in the turbocharger begins to vaporize the coolant at the turbocharger after the engine is stopped. This hot vapor then enters the coolant reservoir tank, which is the highest point of the coolant system.
At the same time the vapor exits the turbocharger, coolant supplied from the right bank cylinder head flows into the turbo. This action reduces the turbocharger temperature. This process will continue until the vaporizing action in the turbocharger has stopped or cooled down.
Beginning with the 1997 model year, the 2.2 and 2.5 engines were made more fuel efficient, more powerful, and were given a flatter, more usable torque curve than in previous years. To achieve these objectives, it was necessary to make improvements and modifications to the Subaru engine lineup. The following are some of those improvements:
• Mechanical valve lash adjusters (reduces friction).
• Lightweight pistons (reduces inertia).
• Short skirt, Molybdenum coated pistons (reduces friction).
• Increased compression ratio (improved power output).
• Improved cylinder head design (improved cooling).
• Improved induction system (improved breathing).
As a result of these enhancements, some Subaru engines may exhibit some engine noise during the warm-up period after a cold startup. This engine noise is a consequence of the engine improvements and is not, in any way, an indication of any engine problem.
The Environmental Protection Agency (EPA) now has regulations in place that establish requirements for on-board diagnostic (OBD-II) systems on light-duty vehicles and light-duty trucks. The purpose of the OBD-II system is to ensure proper emission control system operation for the vehicle’s lifetime by monitoring emission-related components and systems for deterioration and malfunction.
There’s a big difference between detecting only hard faults (OBD-I) and having the ability to actively monitor the system for proper operation, deterioration or a malfunction (OBD-II).
Engines in today’s vehicles are largely electronically controlled. Sensors and actuators sense the operation of specific components (e.g., the oxygen sensor) and actuate others (e.g., the fuel injectors) to maintain optimal engine control. An on-board computer, known as the “powertrain control module,” controls all of these systems.
The picture below of this paragraph shows the location of piston size and main journal size information on all Subaru engines. As the figure illustrates, it is possible to have more than one piston size in the same engine.
Subaru vehicles are more reliable than ever before. To assure their continued reliability, a schedule of inspection and maintenance (I & M) services is prescribed by Subaru of America for every Subaru vehicle sold. A copy of this schedule can be found in the Warranty and Maintenance Booklet located in the vehicle glove compartment.
Subaru vehicle maintenance inspections services are divided into recommended intervals beginning with three months or 3000 miles (whichever comes first). Each additional level in the maintenance schedule (7,500/15,000/ 30,000 miles) adds more maintenance and inspection steps to the process. The 15,000 (15 month) and 30,000 mile (30 month) services are ‘major’ services, and include the most comprehensive range of component checks, part replacements and adjustments.
If you are already familiar with Subaru vehicles, you may have developed a routine when performing a vehicle safety maintenance inspections. Following a set routine allows you to start at one end of the vehicle and end up at the other end, having performed all of the necessary safety inspection steps along the way.
Repetition of the safety inspection may also allow you to commit the steps to memory, but a checklist can be a helpful addition that leaves nothing to chance (or memory). Checking items off the checklist provides a written record that can be shared with the customer and retained for your service records as well.
Recommended steps in a Subaru Safety Maintenance Inspections are also spelled out in the owner’s Warranty and Maintenance Booklet. Some of the steps overlap services performed during the scheduled maintenance program. It could be argued that any scheduled maintenance should always include a Safety Inspection. Most of the Safety Maintenance Inspection steps are based on common sense, but it’s surprising how frequently these simple suggestions are ignored.
FOR SALE: A very rare 1987 Subaru GL-10 4WD TURBO Wagon w/5 Speed Manual & Digital Dashboard.
I only purchased this car about a month ago. It came from the Allentown PA area and had one original owner (me being the second). It needs some work and I do not have the time to fix it up before winter as I originally hoped. With another Subaru project car already in the garage, sadly this one must go. I am hoping to pass this on to another Subaru enthusiast who has the time to make it perfect again.
The car runs and drives great, shifts smooth and even has a little TURBO light on the dash when you give it some extra gas. All of the digital gauges, warning lights, power windows/mirrors, am/fm/tape player, and other electronics work perfectly. The AC blows cold and the HEAT is hot. The interior is clean and maybe a 7 or 8 out of 10… for its age. I noticed that the frame has had some previous rust repairs and will need some additional work around the frame rails.
The engine is clean and runs great, but pretty much leaks from everywhere. The front axle boots are busted and will need to be replaced (new axles are included in sale). I have the original owners manual and “added security” paperwork, the 1987 Subaru sales catalog, the original keys as well as some extras, and a Haynes Repair Manual. The car will be detailed with a full tank of gas at time of sale!
I am only asking $3800 or best offer. I have the title in hand! If interested in seeing the car or have an questions, please contact me by email. Thank you!

This is a step by step guide on installing steering rack bushings (whiteline) on a 08+ WRX/STi. This needs to be done the right way and all the bolts NEED to be torqued with a torque wrench to factory spec for the car to be in a safe operating state.
1.) Remove the under tray. There are 2 12mm bolts towards the front, 1 12mm bolt on the rear, 2 clips on the rear. and 2 plastic pop-out clips on the sides near each wheel well.
2.) After removing the under tray you will need to remove 10 14mm bolts holding the cross member support brace (otherwise known as the jack plate) in place. The bolts that are to be removed are circled in red and yellow.
Note: The bolts circled in yellow are secured by nuts on the topside so you will need the 14mm wench as well. These bolts are torqued down pretty tight if they have never been removed before.
3.) Once the cross member support is removed the steering rack will be exposed as pictured below. Note the location of the 3 bushings denoted by the red arrows.
