Honda Integra DC5 Track

The S1 version has tuned suspension, stronger brakes and an extra 30+ BHP.
Visual exterior mods include a 無限 MUGEN spoiler applying more downforce and Enkei RPF1 rims, alongside its new brakes and calipers.
Interior mods include a new Nardi Deep Corn steering wheel and Defi ADVANCE BF gauges.

In Japan, the Integra was introduced in two versions, the Integra iS (later renamed Integra Type S in the 2004 refresh) and the Integra Type R.

The Integra Type R, sold in Japan had reduced weight, a 220 PS / 164 kW / 217 hp K20A I4 engine (Japan-only; Oceania models have an engine similar to the Acura RSX-S), 6-speed close-ratio manual transmission, as well as a helical limited slip differential (LSD), stiffer springs and shocks, high intensity discharge projector headlights, aluminum pedal set, 4-piston front Brembo brake caliper, 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 Type R lacked many of the luxury features (like vanity mirrors or side airbags) in the Type S, true to its racing heritage. The C package on the Type R added various accessories like the rear window wiper, remote control, folding mirrors. Type R had choices of black/blue/red interiors (including colour matching Recaro seats), depending on exterior colours. Refreshed Integra Type R had the option of either the high wing, or the trunk lip spoiler. Additional interior and exterior accessories were available from Honda's Modulo line. 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.

The Honda K series car engine is a four-cylinder four-stroke engine introduced in 2001. The K series engines are equipped with DOHC valvetrains and use roller rockers to reduce friction. The engines use a coil-on-plug, distributorless ignition system with a coil for each spark plug. This system forgoes the use of a conventional distributor-based ignition timing system in favor of a computer-controlled system that allows the ECU to control ignition timings based on various sensor inputs. The cylinders have cast iron sleeves similar to the B-series & F-series engines, as opposed to the FRM cylinders found in the H-series and newer F series engines found only in the Honda S2000.

Engine specifications would consist of Chromoly Flywheel, Higher-Tensile Strength Connecting Rods, High Compression Pistons, Stiffer Intake Valve Springs and Exhaust Valve Springs, Higher-lift Hollow Camshafts with more duration, and 2007-2011 Cylinder Head Intake Port Surface Polishing and Exhaust Surface Port Polishing used in NSX-R. The JDM K20A Type R engine block would be removed from production assembly line by an experienced Honda engine technician to torque the connecting rod bolts to factory specification by hand using micrometer to measure connecting rod bolt stretching. Then the JDM K20A Type R engine block would be returned to the production assembly line to complete the engine building process.
