Background
September was the month and 1987 was the year, this is when the fourth generation of the Civic was first available. They ran a short but hard hitting 4 years when they ceased to be available in September of 1991. This tiny little econo-box set the standard for Honda at the time with all the advanced-for-the-time technology they crammed into it. With it's double wishbone suspension it could carve the twisties and power down straight aways with it's "new" VTEC system. Even though most of us wouldn't get a taste of this mind-boggling VTEC system until it's debut Stateside in 1990 with the NSX, we still had the D16a6 that came in the Si. The car being so small seemed to be catapulted down the road by 107 snarling ponies.

USDM
Honda, being the amazing company it is, couldn't just sit around and let the Civic run it's course unchanged could they? No they couldn't stomach the thought so some changes, or as alot refer to it as the "facelift", where made for the 1990 model year. Up front they beefed the bumper up and ditched the little bumperlights and replaced them with a light that was more longer and more rectangular. These where clear with an orange insert. Also they ditched the dip in the side moldings and with with a smooth (but ugly) moulding. This wrapped around both bumpers and straight down the side of the car. On the inside they decided to move the seatbelts from the pillar to the door. This meant the handy pouch on the door would have be done away with. The cluster cover changed shape to. It got more rounded.

Motors
Through all 3 of the markets there are a total of 20 engines. These engines came in a variety including single and dual carbed, and dual point and multi point fuel injection. The base models where the 1.2 SOHC single carborated for the JDM market. The EDM base model was the 1.3 SOHC single carbed. For the American market it is the 1.5 dpfi SOHC which came in the Standard which is the base model and the Dx. Following the 1.5 is the 1.6 SOHC which was available in the European as a 1.6i and American market in the Si. After the 1.6 SOHC came the 1.6 DOHC ZC motor. This was in the JDM Si. The infamous B16a came in the Japanese top model hatchback SiR starting in 1989. There where 2 models, the SiR and the SiRII. The SiR is the base model with front and rear disc brakes and double wishbone suspension. The car came factory with front and rear anti-roll bars, ac, and an optional LSD. The SiRII's features added ABS brakes, a sunroof, powered windows and mirrors, among other things. This had 160 hp. A variation of this motor, the B16a1, came in the 1.6i-VT in Europe.
