Is there any sort of aftermarket fuel injection chip for a 78? I know there is one for the later models.

Also, is there much of a choice for new injectors?........as it pertains to more power.

Maybe a couple silly questions, but any advice would be great!

No, there is not.

....ok, I thought so. Does that pertain to the injector as well?

THe only "chip" I have seen advertised for a 280Z is actually a resistor that goes inline with the temperature sensor and fools the efi into thinking the car is always cold to enrichen the mixture. There have been a few companies that modified the ecm on the board level, and sold the unit completely remapped, but because the ECM in a 280z does not have a removeable or modifiable eprom or the like, and because the ecm circuitry is not interchangeable over more than a two year period, there was no cost effective upgrade developed for the mass market like current "chip" upgrades.

you can swap injectors, change the fuel pressure(increasing it pushes more fule through a given injector over the same pulse width), or change out the whole EFI system to another standalone system or even carbs!

Most of this type of modification questions would probably be better asked on HybridZ.org. Most of the members here modify their cars only slightly if at all. On HybridZ pretty much anything goes...fast!

That isn't said to push you off, only to get you to the site with more detailed answers from a greater number of members who have been, are going, or plan to go down the same road.
