Acura Integra (Production of North American Markets)
The Acura Integra, sold as a Honda in most of the world, was a small, sporty vehicle sold primarily as a hatchback. It was Acura's smallest, least expensive model, designed to offer a competitor to vehicles like the Volkswagen Golf GTI, which was the most well known and popular "hot hatch" of the 1980s when the Integra was introduced. Although a sedan was available for the 1986-1989, 1990-1993 and 1994-2001 generations, it was dropped when the vehicle transitioned to its current fourth-generation "DC5" platform, sold as the RSX in North America. Enthusiasts refer to the Acura TSX as the second coming of the Integra GS-R sedan.
First generation (1986–1989)
The vehicle debuted in Japan in 1985 as the Honda Integra before going on sale a year later in North America as part of the then-new Acura lineup. Three and five-door hatchback bodies as well as a traditional four-door sedan were available, with a 1.6 L DOHC 16-valve engine powering all three. The engine was the vehicle's most publicized feature, as DOHC, multi-valve engines were anything but commonplace in entry-level models at the time.
The Integra shared its platform with the less-sporty Civic, although it featured a small list of key upgrades over its lesser stablemate to help merit a price increase over the CRX Si, which was otherwise the sportiest compact vehicle being offered by Honda/Acura; enlarged 4-wheel disc brakes replaced the small front-disc/rear-drum setup used by the Civic and CRX, suspension calibration was re-worked, better tires were used and a 113 hp DOHC fuel injected 16-valve engine was used in place of the SOHC, 90 hp unit from the CRX Si. Combined with sleeker styling and a nicer interior, buyers were effectivly convinced that the Integra was worth the extra money, and nearly 228,000 units were sold during the four year run of the first generation model.

The model was not without its shortcomings though; despite having 113 hp and a reachable 7000 rpm redline, the new DOHC engine had little torque and needed to be wound up quite a bit to make full power, leading to criticism that the model wasn't well-suited for day to day driving on surface streets, but was better tuned for spirited driving down tight, windy roads.
Second generation (1990–1993)
Acura debuted the second generation Integra in 1990, now powered by a new 1.8 L engine making 130 hp, giving the model a necessary boost in performance. The three-door hatchback and 4-door sedan body styles continued to be available, but the 5-door hatchback was discontinued due to poor market reception.
Trim levels for 1990 and 1991 included the RS (base model), LS, and GS. The 1991 GS could also be had with a leather interior, which made it a sort of "deluxe" model, and featured its own model number.
For 1992, Acura added the GS-R trim level, powered by a stroked 1.7 L version of the very successful B16a engine already in use in the Japanese-market Integra. It featured a VTEC system, as found in the then-new NSX, bumping output to 160 hp. Other features exclusive to the GS-R include the charcoal grey cloth interior (leather as a rare option), body-colored trim and front lip, and the third brake light mounted in the spoiler. Sunroof, power everything, and 14 in 6-spoke aluminum wheels came standard as well.
Other small updates came on to all trim levels in 1992, namely new front and rear bumpers, a new steering wheel, new taillights, new ECU, chromed interior door handles and an increase in power to 140 hp for the non-VTEC engine.
The second generation was the last Integra to be sold without airbags in the United States. Motorized passive seat belts were used instead. Canada and the rest of the world got regular active seat belts.

This generation also saw Acura make a bit of a marketing shift. Prior to the 1991 model year, Acura had made a minor point of the supposed understated elegance of minimal exterior badging. Therefore, from 1986 to 1990, the only external clues to any Integra's identity came at the rear, where badges for "Acura" "Integra", and the trim level appeared. For the 1991 model year however, Acura's "A" logo appeared for the very first time on the front of the hood, as well as between the taillights. Every Integra made since then has had the "A" badges. 262,285 units were sold from 1990 to 1993.
Third generation (1994–2001)
Zenki (former) (1994–1997)
Acura debuted the third generation model in 1994, now based on the all-new Civic that had been introduced in 1992. Standard power increased to 142 hp, and the GS-R received a dual-stage intake manifold and a displacment boost to 1.8 L, bringing power up to 170 hp.
A Type R model was added for the 1997 model year, powered by a highly tuned, hand-finished variant of the GS-R's engine, producing 195 hp, meaning it made more hp per Litre than the Ferrari F355's V8. Although impressive, the Type R was still hampered by some criticism; its maximum torque output of only 130 ft·lb at 7000 rpm meant that the engine would perform best from 5700 rpm up to the 8400 rpm redline. Although the engine's "split personality" and unusually high capability to rev made it popular among hardcore enthusiasts, it cost the vehicle points in comparison tests where drivers noted that the vehicle was too hard-edged, loud and rev-hungry to be an easy daily driver.

Kouki (latter) (1998–2001)
Despite some popular demand for a new Integra model for 1998, Acura chose to give the third generation model a slight facelift and re-release it. The 1998 Integra had slightly larger headlights, a more aggressive front bumper, all-red taillights, and a revised rear bumper. There were also some minor cosmetic changes to the interior, and small revisions to the electrical and mechanical components. The GS-R edition received 6-spoke "blade" style wheels as a stylistic change. Once again, the Type-R saw a limited release in the US.
Type R
The Type R was the pinnacle of the Integra line. It had many exclusive features found on no other Integra.
The Type R's B18C5 engine contained more key differences than just some manual assembly steps and an increased redline. The B16A's cylinder head returned, with differently shaped combustion chambers and intake ports compared to the regular B18C in the GS-R. Molybdenum-coated, high compression pistons and stronger-but-lighter connecting rods strengthened the reciprocating assembly. Two extra counterweights on the crankshaft altered its vibration modes to enhance durability at high RPM. The intake valves were reshaped with a thinner stem and crown that reduced weight and improved flow. The intake ports were given a minor port and polish. Stiffer valve springs resisted float on more aggressive camshafts. Intake air was now drawn from inside the fender well, for a colder, denser charge. That intake fed a short-runner intake manifold with a larger throttle body for better breathing. An improved stainless steel exhaust collector with more gentle merge angles, a change to a larger, consistent piping diameter, flared internal piping in the muffler allowed easier exit of gasses. A retuned engine computer also contributed to improve power output.
The transmission was upgraded with lower and closer gear ratios in second through fifth gears, in order to take advantage of the additional rev range. The North American version retained the same 4.4 final drive throughout the Type R's production run, unlike the Japanese version, which in 1998 changed to a 4.785 final drive along with revised gearing. The clutch disk had a slightly smaller swept area, for improved bite. The GS-R's open differential was replaced with a torque-sensing limited slip type.
The chassis received enhancements in the form of reinforcements to the rear wheel wells, roof rail, and other key areas. "Performance rods", chassis braces that were bolted in place, were added to the rear trunk wall and rear subframe. The front strut tower bar was replaced with a stronger aluminum piece. Camber rigidity was improved at the rear by increasing wheel bearing span by 10 mm. The Type R's body also received a new functional rear wing, body-colored rocker panels, and 5-bolt hubs with special lightweight Type-R wheels. Under those wheels was a much larger set of disc brakes, front and back. The tires were upgraded to Bridgestone RE010 "summer" tires.
The Type R received very aggressive tuning in its suspension settings. All soft rubber bushings were replaced with much stiffer versions, as much as 5.3 times higher in durometer readings. The springs and dampers were much stiffer, with a 10 mm reduction in ride height. The rear anti-roll bar diameter was increased to 22 mm in diameter. The front anti-roll bar retained the same size, although the end links were changed to a more responsive sealed ball joint as opposed to a rubber bushing on the lesser models. The result was a chassis with very responsive, racetrack-ready handling that ably absorbed mid-corner bumps well. Mild oversteer was easy to induce with a lift of the throttle, and during steady-state cornering the car maintained a slight tail-out stance.
The interior was stripped down to reduce weight. The air conditioning system was removed and nearly all the sound-dampening material was eliminated. This provided for a much noisier ride, but since the Type-R was a racecar for the street, most owners didn't mind.
301,103 Integras were sold from 1994 to 2001.
