Thinking about changing out fuel pin installing 100 hp injectors and doing turbo. Any recommendations? Would I have to add a boost pump to go to that size injectors?
I have difficulty getting to your EGTs with my current setup. I didn't think stock injectors could even get there.

Shop your local used ads and visit some diesel shops... I got my used turbo and injectors for less than the exhaust kit. I haven't even spent $1000 in parts since I got this truck 2½ years ago.

I haven't needed a larger outlet yet, but Pacbrake makes one.
