I'd reccommend a gear upgrade too. 3.73s would do nicely.
The KB 2V intercooled kit is a get
"bolt on" if a power adder is a bolt on.
The best part is that you can run stock internals and accessories but I think it's best to ensure you fuel requirements don't slip.
A stock rear should hold for most drivers who spend little time at the track and most of the time onthe highway to work.
The twinscrew design is more efficent than other ROOTs blowers and KB did a great job with this unit.
