It's been a long and arduous journey, but Project Turbo KA24 has finally been completed. Over the past couple of months, Naoto Negishi of NPD has dedicated long hours to complete this project. Since we last left off, the entire powertrain was installed, along with most of the necessary hardware to propel the engine to our targeted goal of 750 hp. But just as the human body doesn't survive off the heart and lungs alone, we conclude the final chapter of our build by developing the brain, veins and nervous system of the KA24, before heading off to the local dyno to see if the engine has what it takes to meet our power goal.

Project KA24 Turbo - Tech Knowledge
Final Verdict
Although it took a great amount of planning and work, our initial goal of building the stereotypical junk motor into a viable monster engine has been met. More so, we hope that it has shed some light on the process of building a high-output race engine. Although it may have seemed tedious, all the exacting measurements paid off in the end.
