The 1990 Acura NSX marked the introduction of the VTEC DOHC to the United States. With an increase in engine performance and fuel mileage as well as a decrease in emissions, the DOHC VTEC was built into several Honda car models; including, the Honda Del Sol, the Acura Integra and the Honda Prelude.
The first thing to notice is the engine and its integration with the other parts of the car. This is what is known as the swap feature. The H22A and H22AR engine types have been installed in the Accord to enable the swapping feature. This means it lets you implement a few changes to the sports parts general arrangement. This cuts the tweaking often necessary. The second thing is that there has to be consistency between the engine and its exhaust, cooling, intake and fuel system. Even more flexibility is achievable by changing its parts with the parts of another successful car model. A modified 4-3-1 header from a 90-93 model Accord works fine for the exhaust system. Suppose you want to modify the intake system to get faster driving. You will then have to alter it with a MAP taken from a 90-93 civic DX Mount.
When you mention "Honda Accord" most car enthusiasts will think reliable; but boring, economical transport. The Honda Accord Coupe released for the 2009 model year needs new thinking when you hear those words. You should think "fast and attractive." An Accord without back doors does not truly describe the Accord Coupe. The styling is the feature that jumps out at you. For me, it's a cross between an Aston Martin DB9 and the BMW 3 Series.
Honda has a great reputation for its use of cutting edge technology in its engines. The VTEC; Variable Valve Timing & Lift Electronic Control, is no different. Once again, it gives Honda a clear edge over its competitors. An early 1980's invention by development and research engineer Ikuo Kajitani, the VTEC is known today as having grown from the revolutionary modulated control valve system. The 1983 Honda CBR400 was its first implementation. Other manufacturing companies have developed their own models but Honda pioneered and perfected the technology; then introduced it into widespread production.
