I would go with the street heat unless you are planning on adding a little bigger cam. You really don't need the extra rpm potential provided by the track heat. If you plan on adding a bigger cam and maybe some head porting go with the track heat.
Also on the EFI I would go with a dry n20 kit and not the wet to help eliminate the chance of a nitrous backfire through the intake.
