K series NA or B series Turbo???

[GTRVspec95]

so a turbo b-series isn't good for track?

i'm contemplating over whether i should turbo my b18c7 or go k20.

i want to do some track but also drag, which one do you guys think is best for me?

Think of it this way ...

The turbo is going to give you a real big hit in terms of power but if your going to track race it this power increase also generates a lot more under bonnet heat over time.

Controlling under bonnet temperatures on a track car is the key to getting longevity and performance out of the motor.

Personally I'd consider the B series turbo if you where going to drag race it at night at the occasional test and tune, but I'd never consider this route for circuit work unless you have a substantial budget to forge the motor and add all the necessary cooling hardware.
