im planning out my turbo set up right now and im figuring it out in stages.. first is revhard stage 2 w/ tial wastegate at 5psi on stock injectors.. then later upgrade to larger ingectors and a haltech, i want injectors that are good up to 15psi but i will only be running at 8-9-10 till i do work to the motor.. whats size injectors would i need and will the fuel pump and fpr that comes with the kit be good enough to support them?

 

if you're getting a haltech you wont need the FMU. the stock regulator will work fine. Id say go with at least 550's. those can support somewhere in the vicinity of 380 hp. any 255 intank fuel pump will work great with the haltech and large injectors.

 

how much boost can the stock injectors hold up too? ive heard that at even 6psi the fuel pressure is just so high its really risky.. i want to run 9psi as soon as possible but i will have to wait for a little till i can afford larger injectors and the haltech.. would it be a bad idea to boost 9psi on stock injectors only when racing? im trying to decide on whether i should just get a boost controller and a turbo timer, or spend extra cash and get the haltech..
