6.7 Diesel turbo (he351ve)

Diesel turbos have different seals. I think they will leak oil with a gas motor vacuum behind them? Heard that somewhere... but you can always buy a gas motor seal for it. Guys use huge turbos on 8000 RPM 4 bangers and they run 30 lbs boost, your 340 would haul *** with 12psi at 5400 RPM. 2 small ones are sometimes better than 1 big one. Plumbing is almost easier with 2 also, just 2 sides to a hat.
