If you can find a turbo kit the manufacturer will probably tell you what injectors you need. There are supercharger kits for the Duratec engine. You can check to see if one is available for your year car.
here is the easy/inexpensive way... > https://www.summitracing.com/parts/nxo-22-90000? seid=srese1&gclid=Cj0KCQjw9tbzBRDVARIsAMBplx- jgNEbrS06na8s7phGGa8eqQgQ7aAplx2LOJ6WiJNurbREaooNqAMaAtHZEALw_wcB
what about an upgraded fuel pump as well? or would the injectors do good enough?
I think this all depends on the amount of boost. If you stick to what your stock engine will take (maybe 4psi) you may not need any upgrades. The kit seller should have all the information you want. I looked online and I am not sure you can find a street legal kit (smog legal) for you car.
i live in florida so we dont have ot pass smog lol
