[3] In concordance with the introduction of the Integra's platform mate, the seventh-generation Civic being introduced in 2000, the Integra joined the Civic in abandoning Honda's traditional double wishbone suspension at both ends and adopted MacPherson struts in the front and trailing arm type suspension in the rear along with the new K-series engine supplanting the B-series.

The interior received new trim and gauge clusters, an immobilizer and alarm became standard, the body became stiffer, the suspension springs were redesigned, and the car's tendency to bump steer was reduced.

The JDM Type R had reduced weight, a 2.0L DOHC i-VTEC 4-cylinder K20A engine that output 217 hp (164 kw)  (Japan-only; Oceania models use an engine similar to the RSX Type-S), 6-speed close-ratio manual transmission, as well as a helical limited-slip differential (LSD), stiffer springs and shocks, high intensity discharge (HID) bulbs paired with specially designed reflector headlights (different from all other RSX models), aluminum pedal set, 4-piston front Brembo brake calipers, 17-inch 5 double-spoke wheels on Bridgestone Potenza tires, Recaro suede seats/matching interior, leather-wrapped MOMO steering wheel, body trim, front strut bar, and more.

The C package on the Type R added various accessories, such as a rear wiper, remote control, and folding mirrors.

Modulo accessories offered include interior trim (shift knobs, decals, etc.

), foglights, aero kits (front/side/rear bumper enhancements), wing spoilers, alloy wheels, push button start, upgraded speakers, and navigation.

They lacked the Brembo braking system, used the 200 hp K20A2 in place of the slightly more powerful K20A, and regular 16-inch 5-spoke wheels, painted in gun metal or white, were used instead of the 17-inch, 5 dual-spokes.

However, the Australian Type R does retain the JDM model's helical limited-slip differential, and full Type R interior (MOMO steering wheel, aluminum pedals and shift knob, Recaro seats and color matched carpets) and aero (wing and front/rear bumper lips).

The RSX came with the 160 hp (120 kW) 2.0L DOHC i-VTEC 4-cylinder K20A3 engine throughout the entire production run.

The base model RSX was available with either a 5-speed manual or a 5-speed automatic transmission with Sequential SportShift and Grade Logic Control.

The Type-S included additional features such as sport seats with perforated leather-trimmed interior, sport-tuned suspension, gunmetal painted wheels, 11.8-inch ventilated front disc brakes, larger sway bars and a Bose 7-speaker sound system (including a subwoofer mounted on the spare tire) with AM/FM tuner, cassette and 6-disc in-dash CD changer.

The Type-S received a higher-output engine which included the camshafts, b-pipe and muffler, 4.77 final drive ratio, crankshaft pulley and the intake snorkel duct from the Japanese Type R. The "A-Spec Performance Package" was a dealer-installed option for the Type-S.

The Premium model added a power moonroof, 16-inch alloy wheels and heated leather seats.

The Type-S came equipped with a 200-210 hp (depending on the model year) 2.0L DOHC i-VTEC 4-cylinder engine, larger front brakes, a BOSE sound system with a spare tire-mounted subwoofer, stiffer suspension, an oil cooler and an upper strut tower bar.

The National Highway Traffic Safety Administration (NHTSA) has determined crash test ratings of the RSX.
