Sorry JohnnyBM931A2 the HP & Torque is just about even between the NHC 250 and the 8.3 6cta motors as they come from the OEMs and the NHC will actually have more bottom end torque when pulling away from a stop light but once the turbo spools on the 8.3 it's pretty much even. Where the big difference comes into play is the ease that the 8.3 can be "turned up" to and still have good longevity.
