im unsure of what fuel injectors im going to need. im going to be running a small t3 turbo on my 420a with a whalbro fuel pump and im unsure how much cc im going to need for best results. anyone have an idea of what cc injectors would be best for me? i wont be running more than 8psi im sure so with that in mind suggestions or recommendations would be great :]

T3 doesn't tell us anything aside from the fact that you're using one of the most common types of exhaust manifolds for N/T to turbo conversions on DSMs and Hondas. What type of engine management will you be running? What kind of turbo exactly?

Try researching MegaSquirt. Its the only fuel management option I know for the 420a when you go with boost. Also look into a set of the 450cc injectors depending on the trim size of the turbo and fuel delivery. You will most likely need an AFPR as well.

Look at spending about 1500 - 2k on a dependable setup.

Get a 12:1 fmu and keep the stock injectors. It's the basic starting setup.
Although, as rush mentioned, MS would be the best option. However, most people don't want to go through the hassel for just running around 8psi on the basic Star kit.

You'll have to get at least an SFMU for fuel managment, because of the larger injectors.
