Did you guys get Cordia/Tredia turbos? They came with a G62B ECI turbo engine which would also make a no brainer install on these trucks. The blocks on these particular engines are not monster HP beasts as they can be prone to block failures around the 300 hp mark (the wall of the block around the engine mounts can tear apart) A few guys here have messed with them and one well known engine builder squeezed 380ish HP out of one with forged internals but it ate itself during torture testing.
