ok i have all the parts i need to install my gt3582 with .63 exhaust housing. but all i have for fuel is a walbro 255lph, stock 04 injectors, return fuel setup, and a map clamp. im running 11.5 afr with my stock turbo at 22psi, but i want to know how much boost can i run with the gt35r befor i need a piggy back and injectors. i was thinking around 10-12psi wich would net me 320-350hp. don't get me wrong i will be going with a aem pnp F/IC and 750cc injectors but after all the money i spent on my gt35r setup im short on cash right now. im also running water injection with a 5gph nozzel. and im planing on hoing to a bigger nozzel with the gt35r setup.
