HKS DLI and td coil packs 1000hp no issues, we know they work.... but they aint going to fix a car with other issues.

We had endless dramas with another car over 22psi and even a new set of splitfires did not work.... fitted new std itmes and the HKS unit and bang just shy of 500kw no missfires at all... removed hks unit and it misfired refitted it all good.... proof enough for me.

Get yourself a good 30A plus fused automotive relay and cut the +12V supply to the coils and connect it to a relay on pin 87. Run a high current wire from your alternator terminal and connect it to pin 30 on the relay. Ground pin 86, and connect pin 85 to where the coils used to get their +12V from (the loom). This allows much more current flow at the coil as there is less voltage drop across the length of the wiring in the loom.

Thanks for that very good instruction :-)! I will modify this weekend!

But one Question I have: I run the R33 series 1 GTST with the amplifier (not supplied from HKS twin power ignition systems). Have I to set the relay after or before that amplifier. I think before - right?

Thanks and best regards from Germany

After Vik. The main goal is to supply power to the coils. The ignitor module operates from earth to the +5v signal supplied to the unit from the ecu (when the coils are fired).

There should be 6 inputs and 6 outputs, plus a single earth. The conneciton for that earth is the next most important thing. Always make sure that earth is good, and solidly bolted to the engine, and adding a 2nd earth strap from the chassis to the engine or gearbox isnt a bad idea too.

I often had issues with fouling plugs before fitting a twin power as previously stated. But since i fitted the MoTeC ive removed the twin power and i haven't had any fouling or misfire issues, even at 11,000+rpm 40psi.

Changed to a different trigger set-up though so that may have something to do with it and the car had a Power FC ecu in it when it was having issues.

Weird :P

Paul, what ignition are you running with te motec? standard coil set-up? I've got a motec in my new 32 and been thinking a bit about ignition lately.

i was looking for a post like this, basically i should run 1.1 mm gap on my new plugs copper ngk bkr7e, i got a haltech ecu and holset hx35 with meth, and more gap is better

    • Hmm... From my experience you get about 0.25° camber change per mm of RUCA length change. So, to correct from -2.5 up to less than -1° (or, more than -1° if you look at the world as a mathematician does) then you'd be making 6-8mm of length change on the RUCA. From a stock length of 308mm, that's 2-2.5% difference in RUCA length. My RUCAs are currently very close to stock length - certainly only 2-3mm different from stock. I had to adjust my tension arms by 6mm to minimise the bump steer. That's 6mm out of 210, which is 2.8%. That's a 2.8% change on those, compared to a <1% change on the RUCAs. So the stock geometry already has worse bump steer than is possible - you can improve it even if you don't change the RUCA length. If you lengthen the RUCAs at all, then you will definitely be adding bump steer. Again, with my car, I recently had an unpleasant amount of bump steer, stemming from a number of things that happened one after another without me having an opportunity to correct for them. I only had to change the tension arm lengths by 1mm to minimise the resulting bump steer. (Granted, I also had to dial out a lot of extra toe-in in the rear, and excessive rear toe-in will make bump steer behaviour worse). Relatively tiny little adjustments having been made - the car is now completely different. Was horrifying how much it wanted to steer from the rear on any significant single wheel bump/dip. And it was even bad on expansion joints on long sweepers on freeway entry/exits, which are notionally hitting both rear wheels at the same time. My point is, the crappy Nissan multilink is quite sensitive to these things (unlike the very nice Toyota suspension!). And I think 99.75% of Skyline owners are blissfully ignorant of what they are driving around on. Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.
    • What do you have in that bad boy ? Ill go with the 725cc since I'll be going with Nistune ( would definitely like more engine protection but Haltech is too far out of reach at the moment... plus, Ill probably have a pretty safe tune as its a daily, not gonna be chasing peak power 24/7 ahahah ). Are Xspurt a safe choice?  Pete's great. He didnt mention anything about traction arm length so I reckon it may be good. When I get some new wheels/tire later down the road I'll ask him about it and get his opinion on em. I heard from Gary that you've got the bilsteins too, are you running the sway bars too? and what other suspension goodies do you have installed or would recommend?
