good deal or no?

So on a recent trip to pick a part I found a d15z1 sohc vtec off a vx they're asking $550 for the complete motor and tranny(dizzy and vtec solonoid got snatched
) and also 30 day warranty on both tranny and motor (credit only no cashback) looks like some water got in the head (Friday nights rain).
What u guys think?
How much more power does it have than my stock d15b7 auto?
Thanx any and all input will be appreciated...DJ
