Hayabusa Gen 1 1475/1600cc SBD Taper Throttle/ECU/Wiring Harness Kit
SBD have designed a complete throttle body, ECU and wiring harness kit for the Gen 1 Hayabusa engine. We have a range of maps which will be provided as a base map ready to be optimised on the rolling road to achieve the optimum performance from your engine.
The throttle bodies were developed on the dyno to produce the best peak torque and horsepower, their special tapered design and injector positioning were designed to achieve the best result. This kit has the longer air horns which are ideal for use with the longer stroke version (normally 69 – 72mm). These engines rev less than the standard stroke engine and produce a lot more torque, the longer air horns compliment their torque characteristic. They also require a higher flow injector, which is included in the kit.
The wiring harnesses have been specially designed to be as neat as possible.
The ECU & wiring harness will allow the option of adding of a large range of accessories; MBE9MD display, powershift, etc. Please confirm your full requirements when ordering.
If you are running a 1999 model engine, these are equipped with an 8 tooth trigger wheel/generator. This needs to be replaced by either the 24-1 version that was fitted to the 2003-2007 engine or the 24-2 version that was fitted to 2008 onwards engine (you have to replace the rest of the generator assembly when fitting a 2008 onwards).
If your engine is a pre 2002 you will need to have the generator rotor modified.
