Is the WRX Better Than the STI?
If you’re looking for a car with more power, the WRX STI might be the car for you. This car features a center differential controlled by the driver, which can send more power to the front or the rear depending on the conditions. This is a huge plus, especially in colder climates. The STI also features front-wheel drive bias for added traction.
STI has a bigger turbo
The Subaru WRX is an excellent turbo 4WD car. The WRX has won three World Rally Championships and is Subaru’s flagship model. The WRX STI will feature a larger turbo and an edgier body. It will also get a more powerful 2.4-liter boxer engine.
The STI’s stock turbo is a 47-lbs-per-min Garrett GTX2867R turbo. Designed specifically for the 2.0-liter engine, the turbo spools quickly and has good power potential on E85 fuel. This turbo is based on the Turbo Dynamics MDX555-400 turbo, but uses a different compressor wheel. This gives the turbo more power potential and similar driving characteristics.
The WRX makes 258 horsepower while the STI makes 290 horsepower. The WRX’s peak torque is generated at just 2000 rpm, while the STI must rev to 4000 rpm for peak torque. While the STI is more powerful, it’s not as smooth on the road. Its twin-scroll turbocharger improves response and reduces lag.
If you’re interested in upgrading the turbo on your Subaru WRX STI, the first step is to assess your budget. Moreover, you should consider any downsides associated with the upgrade. You can increase the turbo size by buying a turbo upgrade kit, replace the existing turbo with a custom unit, or even switch to an electric or hybrid system.
Turbochargers can be upgraded to increase the air flow into the engine, which will increase power and performance. If you are unsure of whether to upgrade your turbo or not, you should seek the help of a mechanic with extensive experience in engine tuning. A qualified mechanic will know how to make your STI run properly.
The next-generation WRX STI is due to debuting in summer 2022, but no details about the model have been released by the manufacturer. However, Forbes recently reported that the new STI is set to outperform the Mercedes-AMG 45 S. This report is completely unfounded. The Subaru Corporation has no interest in Mercedes-AMG’s 45S, since it’s not the competition for the WRX STI.
When it comes to performance and comfort, the WRX has the edge. Its stiffer suspension provides greater support and stability, while the STI’s suspension and brakes are more compliant. Despite the WRX’s higher horsepower, the STI’s performance isn’t sacrificed for comfort. Most enthusiasts will spend 9 out of 10 in traffic, which means it’s a good thing that the Subaru WRX is more comfortable.
The Subaru S209 turbo has a more powerful turbo than the S208. This turbo has a bigger compressor wheel and turbine. It boosts power to 18 psi. The S209 turbo is based on the S208 and was developed with Subaru Tecnica International. Its 2.5L engine has the same engine configuration as the S208, but has a larger turbo.
The upgraded turbos also require bigger fuel injectors and a bigger fuel pump. They can also require a larger intercooler. Using a bigger turbo also increases the amount of air that enters the engine. Adding more air to the combustion chamber will make the engine run lean and may result in a blow up.
The Subaru WRX is one of the most affordable performance cars on the market. It starts at $28,500 for a base trim, but goes up to $38,200 for the STI Limited. The WRX STI Limited costs a little more, but comes with more bling.
STI has a stiffer suspension
The 2015 Subaru WRX STI features a stiffer suspension than its predecessor, which contributes to 16 percent less body roll. This stiffer chassis also helps to yield super-quick steering response. The car’s body structure was stiffened by adding more high-tensile steel and special stiffening elements. During development, the WRX STI was benchmarked against a Porsche 911 to improve its handling characteristics.
A stiffer suspension is essential for handling a Subaru WRX. It allows you to turn and stop the car more quickly. However, it is important to remember that your suspension can be damaged by lowering the car too much, because extreme lowering can cause the wheels and steering parts to rub against each other. If you’re considering lowering the WRX STI, you should first check if the lowered springs are causing any damage to the suspension.
The WRX STI is designed for rally racing and features a firmer suspension. Its 2.5-liter turbocharged Boxer engine produces 305 horsepower and 290 lb-ft. of torque. It also includes Subaru’s symmetrical all-wheel drive and performance Brembo brakes. Its rally-bred drivetrain and stiffer chassis have contributed to its superior handling.
The WRX is one of the most popular Subarus in the world. Its performance has helped the Impreza become a hot seller in both Japan and Europe. The WRX STI introduced in 2004 and was more powerful than its predecessor. It is priced well for its power and is more civilized. Its cabin has fewer gimmicks and is very functional.
The 2015 Subaru WRX is fully redesigned. Its new styling reflects the latest-generation Impreza. It features a new engine in the base WRX and a stiffer body structure. It also has higher-quality interior materials. Overall, the 2015 WRX reclaims its status as the benchmark for sport compact performance. With its sturdier suspension, more power, and a better handling, the WRX is a great choice for anyone looking for a sport compact.
