All

I have an R32 GTR - with the basic mods - pulling ~300awkw @ 18psi running R34 n1s

I'm having some problems with ignition break down (old coil packs) - so I plan to upgrade to Splitfire coils ASAP

I just wanted to know if anyone has used the new HKS Twin Power (CDI+Transistor) system

available from nengun

does this look like a work while upgrade

Just bumping an old thread :(

Is there any real benefit from having a bigger spark on an engine? I thought it would mean a better burn of the petrol, and the ability to run a larger plug gap?

Surely there must be some benefits?

Is anyone running one, and have they noticed any differences?

edit - found an old post from SK

we use the standard coils up to 650 bhp (400 rwkw), no problems, with plug gaps at 0.8 mm. For over 700 bhp we use the Motec CDI unit with Mercury Outboard coils as they are designed to be used with CDI.

BTW, CDI is not an amplifier of the spark, it provides a multiple firing of the coil for each ignition, not one, single, long spark as is standard (non CDI). Consequently you need a coil that is specifically designed to be fired in multiples, very rapidly.

So CDI with standard coils is pretty much a waste of money and if you are under 650 bhp I wouldn't worry about changing from the standard setup anyway, provided it is in good condition of course.

Hope that helps

Are you saying the hks cdi system is a waste of money with splitfires on r32gtst SK?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
