Parts began to appear slowly, such as open element filters, headers, and exhaust systems. Suspension companies began to market performance springs and sway bars for the Civic. Some people have even gone as far as swapping in '86-'89 Integra motors, 90+ Integra motors, and SiR motors in the search for more power. Keep in mind that the swaps are not bolt-in, and the use of a rather large shoe horn is necessary when fitting other motors into the compact engine bay. Honda engineers were showing that they listened to the people and earned their respect with a versatile car to own and modify.
Fourth Generation 1988-1991Honda's little hatchback really began to take hold of the market after the fourth attempt at styling the Civic. With a little massaging, the car received a sleeker and lower stance. The roofline had a sporty appeal, sloping down toward the rear of the vehicle enhancing aerodynamics. Again, Honda offered three engines to choose from with fuel economy in mind. The Si was the biggest improvement. Offering an engine with horsepower and torque at the century mark, there was finally a new hope for the little four-cylinder. As the new Si caught on, enthusiasts pushed the aftermarket to develop parts.
Many aftermarket companies began to fill the scene with performance parts. Dreams of modifying a four-cylinder Honda and being competitive were now becoming a reality. Suspension kits, all the bolt-ons, and even internal engine modifications began to appear midway during the fourth generation of the Civic. Some enthusiasts pushed the limits with head porting, cam upgrades, and nitrous.
After the release of the 5G Civic, some builders discovered Integra engines and the B16A (DOHC 1.6 liter) engines from overseas would fit in the 4G's engine bay with little modification. By using the DOHC motors, tuning options increased as well as power to weight ratios. Suddenly, this little car was very capable of hanging with some of the domestic cars. Good styling, great gas mileage, and potential for front-wheel-drive horsepower appealed to the younger gearheads. Attention was now on the hatchback and the import scene in general, and it was time to fail or succeed.
