450hp yah with a bigger engine like 2.4, but not b16 its still too small.
But thats your choise try it will see what hapens.

What size turbo would it take to make 500+hp?

This will be a full race car so I want to start where I am and then go over 500hp.

Also what are good cams to use?

The bast choise to go is Precision SC6262 turbo with .63 housing and BLOX Type-B cams. Thats what I'm gonna use you'll see my dyno charts soon.

what info do you have on the blox type C - is C better than B?

I want to get parts that I won't have to replace later as I build more power.

Blox B's are good up to 700+whp, I made 90whp over my B16, amasing power and torck, you will love it.

do you know a good (cheap) place to get them?

from the sounds of what you want, and what you've shown in knowledge in the area, i suggest you go do ALOT of research before you even spend any money.

you say your getting a hondata ECU but that you think you need check valves, and are asking for detailed instructions to install a turbo...

you'll need to build the motor before you can even think about the ammount of power you want to run

so, go read, read some more, and when you think you know what your talking about. keep reading.

theres an assload of info here, all you have to do is look for it

I think they go for $350, thats a realy good price for sacha good cams.
One of our sponsor has them for very good price: https://www.homemadeturbo.com/forum/...ual-valve.html

I would recomand Performance spring and titanium retainers like skunk 2 or BLOX is fine so you could go more rpms like 9,500 for that big of a turbo.
And dont forget to put obd2 oil pump if you dont have one because of that I spoon my rod bearing last time on the dino.

If you do what I'm teling you your car is gonna be very fast... :)

WOW! if you listen to this guy then you are retarded.

You alredy listened...
