Project KA24 Turbo - Breaker Box - Import Tuner Magazine

The SME's Relay Breaker Box centralizes the power distribution and eliminates the need for fuses. Gary constructs this unit and tests it in the same exacting standards as the harnesses.

Since we have the luxury of being down the street from SME, we had SME tech Alvin install the harness, carefully matching the location of the wires to each sensor.

To eliminate confusion and speed the process of installation, every part of the harness is labeled according to its proper location. This eliminates the need for SME techs to be on-site during the installation process.

These flange-mounted receptacles make disconnecting the harness a breeze. Although they can be mounted on the firewall, NPD chose to route wiring through the stock grommet location, primarily to eliminate the need to put any extra holes in the firewall.

Dynapack 4,000 cells are rated to handle up to 1,100 hp-much more than our target of 750 hp.

Although knock data is logged through the Motec, Naoto also utilizes ear phones to listen for any audible detonation through a microphone positioned next to the knock sensor.

Here was where the real excitement started. We moved our project over to Driftspeed in Los Alamitos, CA, and filled it with a full serving of VP C16 fuel. Although the anti-detonation characteristics of C16 are quite good, any amount of significant knock at 2.5 kgf/cm2 (35.6 psi) could spell disaster.

After months of work, this is what we have turned our Cinderella into.
After each run, all the data (rpm, timing, injector duty, knock, A/F, boost) is analyzed to determine the next step to make. Only once Naoto is satisfied with the results, is boost raised to the next level.

Although we could have tried to work out the electrical hiccup at 6,200 rpm, we were more than happy the motor surpassed our target goal-we'll save that project for another day!

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.
