In 1989, Fuji Heavy Industries released the Subaru Legacy, a car that redefined the automaker’s lineup and quickly became a favorite amongst drivers everywhere. Combining safety, reliability, and efficiency, the Legacy has been a mainstay in the Subaru family for over 25 years. Though its design may have changed slightly over the years, one thing remains unchanged: the Legacy’s ability to provide an enjoyable driving experience for all.
“I’m an avid car enthusiast and love to modify my Subaru Legacy. I’ve found that by adding a few simple modifications, such as new exhaust and air intake, you can make your legacy faster than ever before.”
The Subaru Legacy is a great vehicle for all sorts of reasons, but if you notice that it’s having performance problems after driving for more than one year then there could actually be something wrong with your engine. You might have never thought about what causes this type of issue before and not known how to fix them either or even cared. But don’t worry because I’m going to help get things back up running again in no time.
Here are some tips to help your Subaru Legacy go faster.
- Upgrade your exhaust system
- New air intake
- Use Electronic Control Unit (ECU)
- Install new Spark plugs
- Install a larger intercooler
- Install an aftermarket boost controller
- Replace the stock Legacy crank and alternator pulleys
Additional tips: The best way to get the fastest Subaru legacy is by having a car in your control. This means investing in high-performance struts that will give you what’s required for fast driving.
How to Make My Subaru Legacy Faster
I have already mentioned how to make my Subaru Legacy faster, now let me explain in more detail.
Upgrade your exhaust system
When upgrading your car, one of the most important aspects to consider is the exhaust system. An upgraded exhaust can improve performance and make your Subaru Legacy faster. There are many different types of exhaust systems available, so it’s important to choose the right one for your car.
A larger downpipe, like the 3-inch one made by Cobb, will add power to your motor by evacuating exhaust gasses faster. This means that you can get more air into combustion which results in a higher torque rating for any given engine RPM range.
New air intake
Subaru is introducing a new air intake system to make the car faster. The new one should be cold, and it is expected to boost the car’s performance. It is not clear yet how much faster the car will be, but engineers are confident that the new system will improve the Legacy’s speed.
Use Electronic Control Unit (ECU)
One of the best ways is to use an electronic control unit (ECU). An ECU can help improve your car’s performance by modifying how it uses fuel and air. By using an ECU, you can make your Subaru Legacy faster and more responsive on the road.
Install new Spark plugs
Spark plugs are what ignite gas within an engine to make it run. Without spark plugs, your car would not be able to start at all. Replacing them will help give you better gas mileage, fewer emissions, and more power.
Install a larger intercooler
Installing a larger intercooler from AVO is one of the best things you can do for your Legacy. A more efficient unit will allow for cooler turbo and motor operation, which in turn produces a much stronger power output. This addition may be important if cranked boost levels cause extra heat build-up on these components due to increased performance demands or other reasons not related to just straight horsepower amounts that we like to call “boost.”
Install an aftermarket boost controller
There are two ways to safely raise the amount of air that a turbo is feeding your engine. The first is with an aftermarket boost controller, but make sure you don’t go too high and risk damaging it. As delivered from factory settings for reliability this Legacy was conservatively dialed in which will keep things running smoothly without any worries about damage or other problems associated with going over boosting.
A good example would be on twin-turbo setups where there’s the extreme strain placed onto one unit while giving power through another (such as under heavy load).
Replace the stock Legacy crank and alternator pulleys
The stock pulleys on your engine are a pain in the neck, and they’re just about as heavy. Replace them with lighter ones for increased responsiveness.
So, if you want to make your Subaru faster and don’t have a lot of money to invest in the process, try changing out your spark plugs. This is an easy modification that can give you a good chance at better performance without costing too much.
