From what I've seen once you move past a stock LSA with 5 or 10% overdrive you will max out the factory injectors.
Either
DeatschWerks 90LBS are plug and play for the LSA or Injector Dynamics 850.
The image looks like you already have an overdrive (smaller) snout pulley. I would become familiar with this chart. you want to make sure you don't over spin the blower.

You will need a good fuel pump set up. Something like the CTS-V twin pump with a Vaporworks controller.
