I'm just tellin you what the dyno tells me...I had a friend who swapped a JDM SR20DET ripped straight from an s15 by his brother in japan and shipped here. it dynoed at 184 and 205.
I think this is where some of the confusion is coming from. You quoted crank horsepower for the vg33er but seem to be quoting wheel horsepower for the sr20's. This is not an equal playing field at all as wheel horsepower is always quite a bit less then crank horsepower due to the drivetrain loss. Here are the official crank horsepower numbers from Nissan for the following completely stock engines:
vg33er: 210hp, 246lbs of torque
s13 redtop/blacktop sr20det: 202hp, 203 lbs of torque (sometimes rounded to 205hp)
s14 sr20det: 217hp, 203 lbs of torque (sometimes rounded to 220hp)
s15 sr20det: 247hp, 202 lbs of torque (sometimes rounded to 250hp)
s13/s14 ka24de: 155hp, 160lbs of torque
