Most people never consider the choice of adding a performance ignition to their line up of hi-po parts (with the exception of race-only applications) or adding that extra accessory to gain points at a show. The biggest factor that you will be overlooking when passing on purchasing an aftermarket ignition is the advantages that they have to offer. So why should you add one to your engine bay? Well, for starters, the stock ignition isn't designed for high-performance and produces a relatively weak spark, which does not generate enough current to ignite an engine in a pressurized environment (turbocharged/supercharged). An aftermarket ignition system can throw out multiple sparks at one time to provide a hotter spark, which in turn gives your engine increased horsepower and better gas mileage.
Taking these factors into consideration and using its in-depth knowledge of high performance, MSD Ignition recently added the Digital-6 Plus Ignition Control to its current line of aftermarket ignition systems. The Digital-6 has a wide variety of built-in features, including a two-step rev limiter for consistent launches and over-rev protection, single-stage retard for top-end performance or nitrous control, and a diagnostic LED to assist in trouble-shooting. MSD says this ignition is more compact and produces a more accurate and greater output of energy with less input current due to its 15-MHz microcontroller.
We went to FasTrax Turbo Technologies where they installed the MSD Digital-6 Plus on a turbocharged Celica with a stand-alone fuel injection system, so keep in mind that installation on your import will be different. FasTrax also installed the MSD Blaster SS ignition coil in conjunction with the Digital-6, which is designed to produce high amounts of current without sacrificing voltage output.

Tools necessary for installation are: #2 Phillips screwdriver, flathead screwdriver, wire stripper, crimping tool, and a drill with drill bits from 9/16-inch to 1/8-inch bits to drill or mount your screws.
