Hi guys & girls

My twin power ignition just died recently. I than bought the twin power unit without the harness thinking it was my unit that fried. However, when my new unit has arrived a few days ago and plugged up and I still get the miss fire. This makes me thinking the harness itself.

Does anyone know where I can source a HKS twin power harness for r33 gtst - part number 4399-SN004?

Thanks

Sinista32 - have already spoken to the supplier and i was told it has been discontinued. :unsure:

Kitto - The coils are fine as i have been running it now with 0.5mm gap to be able to run at high boost. with the twin power i'm actually running with 1mm gap and it's fine untill the twin power not firing at high boost.

GTSBoy - the harness itself also have circiut boards, to each plug.

My experience with this silly gold box. It cost me two sets of coils. Brand new OEM ones and splitfires. Bought another set, ditched the gold pretty box and the OEM ignitor (R33 GTR) and ran an aftermarket one and bingo. All good.

Paul - I'm running the splitfire now but with 0.5mm gap with no problem if running 0.6mm i will get miss fire. With the hks i can run 1mm gap with no problem. Well i will give up if it die on me again. Now i have 2 twin power with problem harness. The harness to operating but when running more boost it won't work. It acts like stock harness.

Thanks

it's not the sparkplug because it is firing normal at 27psi with 0.5mm gap stock harness. have already changed 2 sets of plugs previously. Definately the HKS twin power harness.

Does anyone know where i can get the harness fix?

Thanks

      I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.

      Time to decide what’s more import, your power level or your budget because you’re going to struggle to keep both
