That is a vg30i not a vg30e. and even then, it's not a vg30i, but it has the vg30i intake manifold with a carb on it. a vg30e, like what our cars come with stock is going to make more power.

128/159 out of a vg30e. not bad when they are rated at 160/174

9% loss on torque. 20% loss in horsepower. the VG30E head flows HORRIBAD though, it was a motor built for boost, so it does not do well in a naturally aspriated environment.

Other dyno numbers include:
135.7/158.7 - headers (15% hp loss 9% tq loss)
This is obviously a very healthy vg30e.
137/152.8 - stock w/ 210k miles (14% hp loss 12% tq)
151.6/166.8 - same motor as above but with headers (5% hp loss 4-5% tq loss)
As you can see from the above example, increase the flow of the shit that goes through the head, really helps with the HP number!
