I am building a NA B18C1, it has:

Integra Type R Pistons
Skunk 2 Stage 2 Cams
Skunk 2 Adjustable Cam Gears
Skunk 2 Intake Manifold
Not sure what to do about header and exhaust yet...

I am not familiar with the electronics and was wondering if an Apexi VAFC would be enough for me to get this motor running properly... Also, whats the difference between version 1 and 2 of the Apexi VAFC.

Last but not least, would this setup require bigger injectors, or are the GSR injectors big enough?

Thanks, you guys rock.
