N/A 370z

The European FIA GT4 series 370Z makes ~440 hp with stock internals but different heads.

In the USA, the 370Z RC run by Doran Racing will make similar power. The Grand Sport series permits the cylinder head to be changed (use the HR head and not the VHR head) plus a dry-sump lubrication kit and long-tube headers and low-restriction exhaust (no cats).

These engines run at close to 9000 rpm which is where a lot of the power increase comes from.

Such an engine would not last very long in a road car though.

All I can say to the OP (based on over 40 years of involvement in competitive motorsport as a driver in state and national series, and a volunteer event/series official) if leave the car standard (brake pads and brake fluid apart), learn how to drive quickly (and there is no better place to start than AutoX) and when your times do not improve for two events on the trot, then think about firming up the suspension, then progress to stickier tyres and then when you have 2 events where you are not going quicker, think about a bit more torque (torque wins motorsport events, NOT horsepower).
