Default Need help choosing an Injector size.

Im finally turboing my LS. I bought a Revhard 2C Turbo Kit. Alot of people are tellin gme to use prelude injectors. Im not sure what to do. My motor is completely stock, except for the JG intake manifold.

What should i go with. Prelude injector's at 290cc, get some 330cc's or go with the Venom's at 440cc's.

I already bought the entire AEM Fuel management system, i have a type-r fuel pump from inline4. Which injector's would be good to run with this setup.

well how much boost do you plan to run?

I dont think the type r fuel pump is going to really make much of a difference. I would get the Walbro gss342(255lph) fuel pump, 440's or 550's.........

Tell us more about what you want to do

As of right now i only want to boost 7 psi max. Im currently saving up to buy one of the Importbuilders Annialator Block that you can boost 20psi. I wanna run low 12's when i finished, but for now i can settle for mid 14's.

Damn that importbuilders block is nice, but waaaaaaay too expensive.

I would look somehwere else. I got a LS/Vtec, darton sleeved, endyn pistons, eagle rods, and FULLY buildt JG Pro Series head for under 3300 US$ with everything assembled.

Come to our shop, we are maybe an hour away from you. I can set you up with a nice fuel system.

I would sell that intake manifold and get a skunk2. Not unless your gonna be revving between 7k and 10k rpms (i hope you dont on stock LS) that JG wont really make any power over the stock intake.
