Does the 2002 RSX have VTEC?
The short answer: Yes. All 2002 Acura RSX models use Honda’s i-VTEC system, though the extent of VTEC differs by trim.
In detail, the RSX lineup launched in 2002 with two engine options tuned for different performance goals. The base RSX uses a K20A3 engine with i-VTEC on the intake cam (no exhaust-cam VTEC), while the sportier RSX Type-S uses a K20A2 engine with i-VTEC active on both the intake and exhaust cams. This setup produces significantly more power and a higher rev limit on the Type-S compared with the base model.
What VTEC means for the RSX
VTEC stands for Variable Valve Timing and Lift Electronic Control. In practice, it allows the engine to switch between different cam profiles to optimize efficiency at low RPM and performance at high RPM. On the 2002 RSX, the base model has intake-side VTEC, improving high-RPM breathing. The RSX Type-S employs dual VTEC, providing stronger high-RPM performance across both cams.
Engine details by trim
Before listing the key differences, note that both trims share the same basic layout (K-series architecture) but are tuned for distinct performance targets.
- RSX Base (K20A3) — i-VTEC on the intake cam only; roughly around 160 horsepower with torque in the neighborhood of 140 lb-ft. Redline is typically around 7,000 rpm. This configuration emphasizes smooth operation and efficiency for daily driving.
- RSX Type-S (K20A2) — i-VTEC on both intake and exhaust cams; typically about 210 horsepower with torque around 143 lb-ft. Redline approaches 8,000 rpm. This setup targets higher-rev, sportier performance.
In practice, this means the Type-S delivers notably more peak power and a higher-rev ceiling, while the base RSX provides solid performance with greater everyday drivability.
What this means for ownership
If you’re evaluating a 2002 RSX, expect the base model to offer refined, efficient VTEC behavior on the intake cam, with lower peak output. The Type-S, by contrast, uses dual VTEC for a more aggressive power delivery and higher redline, consistent with its sport-oriented positioning.
Summary
All 2002 Acura RSX models feature Honda’s i-VTEC, but the scope differs by trim: base RSX uses intake-side VTEC, while RSX Type-S uses dual VTEC on both cams for higher power. In short, yes—the 2002 RSX has VTEC, with the Type-S delivering the more performance-focused version.
What year to avoid Acura RSX?
All model years of the Acura RSX (2002 to 2006) have been known to leak motor oil due to bad or failing oil pressure sensors. The oil pressure sensor is an important part of your engine because it maintains the engine's oil pressure level.
Does the 2002 Acura RSX have VTEC?
Now, on the all-new 2002 RSX, Acura unveils the latest version of this remarkable engine system: i-VTEC. The "intelligent," i-VTEC system adds new VTC (Variable Timing Control) to VTEC to provide continuously variable camshaft timing - taking the concept of variable valve timing to new heights.
What Acura has VTEC?
Acuras that have VTEC include the Integra, RDX, TLX, and older models like the TL and the original RDX. Many modern Acuras use a VTEC Turbo engine, while older models often feature a VTEC V6 or a turbocharged 2.3-liter VTEC engine.
Modern VTEC models
- Integra: Both the standard 1.5L VTEC Turbo engine and the high-performance 2.0L VTEC Turbo engine in the Type S model are equipped with VTEC.
- RDX: The RDX is powered by a 2.0L VTEC Turbo engine.
- TLX: The TLX uses a 2.0L VTEC Turbo engine.
Older VTEC models
- TL: The TL featured a 3.5L V6 with VTEC.
- Original RDX: The first generation RDX (2007) was equipped with a turbocharged 2.3-liter 16-valve DOHC i-VTEC four-cylinder engine.
