So I'm gonna be running Holley EFI and aux gauges, LED headlights with halo rings will the alternator be able to make enough power? I have a good battery for the car.

If the alternator is too small of amperage to run all of that what's a good replacement and what do you do to swap it so nothing goes wrong? Voltage regulator? I'm also running a gilmer style belt to prevent slippage because I'm running a turbo hence the gauges.

 

More information is needed. What generation RX7 are you using? Will you be using an electric radiator fan? power hungry amplifiers?

 

* Voltage regulators are integrated and internal on alternators.
* Gilmer belts aren’t necessary just because you have a turbo. When I see them on street cars they’re almost always just there for noise and show. If you have them, you probably don’t have a big stereo and amps...because you couldn’t hear it anyway. That just leaves the fan question.
Still, switching to OEM pulleys and belts will probably make things WAY easier if a different alternator is needed.
