Turbo-Kit
"Crazy idea in pure art form"
This is intend to give you a general idea on what is involved when turbo-charging a normally aspirated vehicle. Just about any late 80's to early 90's import cars make good candidates for this project. I owned a few Hondas in my past and they are awesome cars. Although I have never boosted any of them, if I knew what I know now. They would have been some of the fastest econo boxes on the road. The most memorable to me was my red 90 Civic Si with "Nawzzzz" but that's another discussion all together. For this project, I chose the s13 since the potential is almost unlimited in this chassis configuration.
Primer
Back in the early 90's when these cars were still consider new, no one actually have the exact science in this subject. The most common way of hacking a tune were fuel management unit and boost timing retard device. When the engine transition from normal aspiration to boost, a fuel Management unit increases clamping force on the return fuel line to create more fuel rail pressure. The increase pressure forces more fuel out of the injectors. A boost timing retard device also decreases overall timing during the above atmospheric situation. Both devices help compensate the additional fuel and timing requirement of a turbo charged vehicle.
As the years go by, the mystery of the factory engine computer slowly comes to light. Those who came along with the knowledge made a killing in something so simple in principle and kept the secret among themselves. Fortunately there are a charitable few who left enough clues for the rest of us.Continue to Part 2
