Change it to manual if you can, it'll make more difference than anything else.

Franklin Cam Services in Pukekohe have many grinds available as do Kelfords in Christchurch I probably also have a mild RR3 grind Cam here which would suit you. You need to keep the cam mild being street driven and an auto.
Extractors or headers are available from Custom Chambers who were in South Auckland or Stewart Wilkins Motorsport in Australia. There are other manufacturers but i have experience with both of these. You want headers with 1 5/8 Primaries, Secondaries of 2 1/4 with a 2 1/2 exhaust.
A bigger throttle body, cold air intake and good heat shielding is also a worthwhile investment.

But and here is the catch. Before i did any mods to a fuel injected auto 280 especially a cam i would change the ECU. The factory ECU is very basic and not a nice thing. Get yourself an aftermarket ECU, something like a Link. I prefer the Motec but they are expensive. I currently run a Link myself and it is fine but does have limitations. However you wont strike these in your application.
For a similar spec to what you may like contact Bernie Kant on this forum.

Not sure of the pipe sizes of these but may be a good option

Does anyone know if those would fit under the factory 280zx fuel injection?
