MPS Injectors are available in 4 sizes:
The stock Gen 1 Hayabusa has 24.5 lb/hr . They are ideal for dry nitrous and turbo applications where much more fuel is needed. We can flash your 2002 - 2007 Hayabusa ECU with a base map for the 60 lb/hr injectors. This makes tuning easier. Both sizes fit in the Gen I Hayabusa stock fuel rail perfectly. The RCC Billet Fuel Rail ( p/n 84-41.1) is required to use our 42, 60, or 80 lb/hr injector kit in the secondary position on Gen 2 Hayabusas. The kits comes with everything necessary to install including new injector connectors. 42# Injector Specifications:
