I have an 03 lb7. I recently put a fully built suncoast tranny in it. I have rebuilt the motor, i put ppe pistons, a ii cam, carillo rods, arp studs, 42 per over cp3, hamilton springs, efi live and more. The injectors were all 8 replaced about 5k miles ago. The only thing stock is the injectors and turbo. The turbo has a batmowheel and ppe boostvalve and banks big head. My question is what my next mod should be. I either wana put a bigger turbo or new nozzles on. With my budget i can only do one right now, and il do the other sometime around christmas. I was looking for the injectors at either 30 or 40 per over industrial nozzles. And for the turbo a silver 66. Which would i benefit more from upgrading first, and what size turbo and injectors do you recomend. The truck is mainly just a dd and i race it occasionly.

 

you would benefit from the larger turbo, your stock injectors can already get the max out of your turbo.

a turbo is my next major upgrade. Been thinking of an s366

 

I would have to say a Turbo as well! Sounds like your truck is pretty well built!
