I think the connector should be the same.

Yeah Okada are costly but there are other options. T.M. Works specialize in ignition tuning products. I'm using their basic harness:

or you can go further with 16v: http://tmworks-web.jp/products/alpha_eng.htm
and even a few more stages of upgrades.

Their full stage upgrades might be even more costly vs Okada and the debate is still going on which is better.

The Okada doesn't really net much for the investment really. On a ka20 for example with a GT2835 @ 8PSI only gains 7whp and 17tq. Of course as the boost increases you will see a larger gain but it isn't exponentially linked.

I am very intrigued by the idea of using the higher end Vitz coil packs. Wish that there was a spec sheet comparison between them and the standard coil packs. I am sure when we Dyno my newest setup we will see if it would be of any benefit to make the upgrade.

90919-02229 are supposedly the RS coil packs. They are used parts so I decided to purchase 5 pieces as 1 would be a spare. rabbito is over there so maybe he could hook you up with a seller.

Interesting idea with a voltage booster. If there is a real benefit to doing this, then with a bit of tinkering, I think you can replicate the effect with a cheaper unit such as this.

It would all be a matter of finding an apropriate size that would deal with the heat that gets generated from the constant operation.

As a bonus, it's adjustable, so you can crank up the voltage even more if you're feeling brave.

I heard it is not recommended to go above 16v as it may damage or melt your plugs

racecars run 16 volt batteries a lot in the us.no danger I think of burning up your plugs ha ha.
