It’s evident that I’m a devoted admirer of the Acura RSX, as I’m presently engaged in the restoration of one. My ongoing project to rebuild this car is making significant strides, documented on both my YouTube channel and the DC5 Build page. If you’re contemplating acquiring an Acura RSX, the question arises: should you opt for the Base model or the Type S?

Each model boasts its own set of advantages and drawbacks, warranting a closer examination. The Base model caters well to individuals seeking a sporty vehicle sans extravagant features. It’s an ideal choice for daily commutes, offering affordability alongside performance.

Conversely, the Type S is tailored for those craving enhanced performance and power. Sporting a more aggressive demeanor, it outpaces the Base model in speed and overall driving experience.

So, which variant suits you best? Only you can discern the answer. Nevertheless, regardless of your preference, rest assured that both models promise enduring quality.

Performance is invariably a pivotal factor in car selection, and the RSX doesn’t disappoint. Thus, which model boasts superior performance?

The Base model houses a 2.0L engine generating 155 horsepower, catering to those prioritizing efficiency and practicality. However, for enthusiasts yearning for heightened power, the Type S reigns supreme with its 200 horsepower output. It strikes a balance between speed and efficiency, making it an enticing choice for drivers seeking a spirited ride.

Styling

While the Type S and base model may appear quite similar at first glance, they boast distinct style variances that might catch your eye. Specifically, the 02-04 RSX trims share bubble-style headlights reminiscent of the USDM Acura Integra DC2. Yet, upon closer inspection, one trim showcases a different lip kit and side skirts. The base model features unpainted black plastic side skirts, whereas the Type S boasts side skirts painted to match the car’s color.

Moreover, the Type S A-Spec model sports a large rear wing akin to the Japanese DC5R, along with more aggressive front and rear lips. Both the RSX Type S and base model sported the same 5-spoke 16-inch rims from 2002 to 2004. However, in 2005-2006, this changed: the Type S received a refined 5-spoke 17-inch rim, while the base model adopted a multiple-spoke design that remained at 16 inches.

Not only do the mufflers of the two models differ in size, but they also exhibit variations in performance. The b-pipe size for the Type S is slightly under 2.25 inches, offering less exhaust flow restriction compared to the base model, which has a 2-inch pipe size. Additionally, the muffler tip on the base model is thin and narrow, while the Type S boasts a thicker and larger diameter tip.

The primary contrast between the base model and Type S lies in the interior. While the base model features cloth seats, the Type S offers leather seats, imparting a heightened sense of luxury and premium quality.

Transmission

The RSX Type S trim offers a superior transmission with a 6-speed manual gearbox, whereas the base model is available with either a 5-speed automatic or manual transmission. The Type S transmission stands out for its shorter gear ratios, enhancing the driving experience significantly.

Here are the gear ratios for both models:

Engine

The Acura RSX base model is equipped with a 2.0-liter inline-four engine that typically produces around 155 horsepower and is paired with either a 5-speed automatic or manual transmission. In contrast, the RSX Type S features the same 2.0-liter engine but with enhancements such as i-VTEC (Intelligent Variable Valve Timing and Lift Electronic Control), resulting in approximately 200 horsepower and 142 lb-ft of torque. It comes exclusively with a 6-speed manual transmission, delivering a more spirited and engaging driving experience compared to the base model.

If you pop open the hood, you’ll see a big visual difference between the Type S and base model. You’ll notice the intake manifold (PND) itself and the cover is black with a 58mm throttle body which produces much less air flow into the engine than the Type S, which the manifold is made of aluminum (PRD) with a 62mm throttle body. Also, if you look at the bottom of the engine, they have different oil pans, a black steel pan for the base model vs a aluminum silver colored pan for the Type S. The compression ratio of the base model k20a3 engine is much lower at 9.8:1 which can handle the cheapest US gasoline at 87 octane in contrast to the Type S k20a2 engine which has a high compression pistons at 11.0:1 which needs at least 91 octane.
