What's the best ignition system for the FD? How does the HKS twin power compare to MSD or Jacobs? Are any of them hard to install?

 

HKS has to be one of the easiest( not cheapest) mod I ever did. buy the cable if you get one.

 

I have the HKS Twin Power ignition and it was extremely easy to install. It is very small, so you have a few places where you can mount the unit without having any problems locating a spot.

 

The HKS TwinPower boosts the spark on the leading and both trailing coils with one little, super-easy-to-install box. You need more boxes if you want to boost all three with MSD or Crane, etc.

I am not aware of any performance comparison data of the various options. And I don't even know if any of them will boost power on a properly tuned car, but there have been some reports of an ignition box boostig output on some cars, and many reports of the ignition breaking up on a car with the stock ignition at high RPM. Ignition breakup might be fixed by fixing the air/fuel ratio (running really rich can cause such break-up) to better effect than masking the problem with an ignition box. I didn't want to waste dyno time if my stock ignition proved inadequate, so I just got a TwinPower anyway.
