First of all- have you ever driven a 500 hp fwd car? It is too much on the street, it is kinda pointless to want that much power on street tires.
If its for the track, plan on getting some bigass slicks
A t3/60-1 .63 a/r will support 450 whp on the b16, maybe a little more on an h22
You can get the .82 a/r turbine if you want more high end power, but it will spool later.
I got my ball bearing 60-1 for 525 bucks, look around and you will be able to find similar pricing
