Drifting is a driving technique by keeping the car's position turned for as long as possible. Car drifiting required a large horse power so that the car does not lose power at the time of run. Development and analysis of this final task is to know how the procedure of modification of ignition full transistor, know condition of ignition system component that will be replaced with system ignition full transistor. Replaced components are batery, distributor lids, spark plugs, high voltage cables, which are not suitable standart and also platinum units are replaced with transistor units. After performing component analysis performed performance test, from the results of the dynotest data generated, the performance of mitsubishi lancer SL engine before and after the development upgraded from 22.6 HP when using platinum and 30.3 HP on whell when using a full transistor ignition system.
