Hey,

I have got hold of a HKS twin spark unit. However it was off a supra.

Do I need the specific rotary one or can it be wired to work?

 

You may need the harness for the car.

Please State what car you HAVE as there are many types of RX7.

HKS should have a wiring diagram or you can search the TECH sections of the particular Series of car that you have and maybe find some kind of info.

 

From what I recall when doing research into the Twin power, you need to have it be specific for the application. I just bought one, and on the box and on the twin power itself, its labeled ROTARY.

Best bet in my opinion, would be to sell the Twin power to the Supra Guys (I'm sure they'll nab it up real quick) and buy the one specific to your vehicle + vehicle specific harness.

 

Hey,

It's a RX7 FD3S 13B REW

 

You can wire it manually but they have a PnP harness. Much easier
