I'm sure it's been covered a million times over but I'm building my first b20v and want to know what comp ratio and what rod and piston combo anyone has used in theirs for a daily driver I would like to be in the 200-220hp range

 

You can use this site for a good estimate. https://www.zealautowerks.com/bseries.html

I have a b18b1 block, b18b1 rods, b16 pr3 pistons, b16 head and CTR cams. Stock injectors and TB. 193 wheel. If i used RDX, I would have made it over the 200whp mark.

For your build, depending on the compression, go with ITR or CTR cams, or even a Skunk2 pro 2 to make over 220

 

What RPM did you spin the engine to with the stock fuel injectors ?

 

I don't think the RPM's are limited to the size of the injector. I was limited by my rod as its a stock LS rod with ARP. Rev limit was 8100rpm.
