D SERIES 100kw-300kw Injector Upgrade

The factory D series injectors are small at 240cc and cannot reliably support any meaningful boost.
An injector and fuel pump upgrade is highly recommended to unlock more power, ability to run ethanol based fuel and support fuel delivery for higher boost. 
 
Stage 1 (731cc) is ideal for factory internal D series
- 10-18psi on a GT28 (160-180kw on E85)
- Requires Walbro 255 upgrade (compatible with E85 and stock wiring) 
- Great size for most applications. Great idle control and low speed 
Stage 2 (1250cc) Want more? Built motor recommended
- Stock D16Y4 + GT28 @29psi (210kw on E85)
- Walbro 255 is sufficient for 200kw. 200kw+ requires DW300 fuel pump and wiring upgrade 
 
Included
- 4 x Genuine Bosch injectors
- 4 x Injector adapters to suit factory fuel rail
- 4 x USCAR connectors and pins 
- Injector data for Haltech NSP
