Cool, your setup rocks so it obviously works!

Are you using a non R33 GT-R set of Splitfires that don't have the inbuilt ignitors?

R33 GTR coils don't have ignitors built in, only the 34's do. But yeah, I threw the standard ignitor module which lives on the cover in the bin, wired the new one in and bingo, no more missfire. Same thing happened with Joeys car at around the same power (400 ish rwkw).

Also sent one to Melbourne (DAZ) and it worked for him too. He is making close to 500 kw on chequered's dyno.

I've got the AEM ignitor (http://www.aemelectronics.com/8-channel-twin-fire-ignition-module-670) which I presume is much the same thing as the Morristech.

I'll get a set of Splitfires and see how we go!

Thanks for the plug Richard :)

The Z32 upgrade sadly isn't a plug and plug affair for the R32/R33 GTR, however is for the A31/C33/R31/Z32 owners with the PTU with square electrical connectors; for the R32/R33 this kit does make for an easy conversion if you're handy with a wire unpicker. We can also help with a new coil pack harness.

when I bought my haltech, I got a free HPI6 in the deal.. I was interesting in using it but read on some supra forums having quite a few problems with them... So I'm unsure at this point if its worth it. I also asked haltech about it and they were answer were that the std unit should be similar to the HPI6..

Anyone heard /used the kenne bell boost-a-spark ? It appears to be a better optien than the hks box.

^ interesting. Thanks for the 'feedback' on the HP6

info to consider

One would think that current technology would be more effective/efficient compared to 22yo technology.

Amplified spark should provide greater spark and burn efficiency.

Unfortunately I cant find tech specs and internal diagrams of either to compare.

Obviously those who have had issues at greater power levels have resolved these with after market units. Morristech etc..

So that speaks volumes.

Question now Is - Is there a benefit for lower power levels? Say 300 to 400kws

Ps. CobrAA, If your looking to make bucks on your freebie let me know how much you would like for it :yes:

The later gen AEM gear seems to be great value for money.

In my opinion it's a better option than a straight ign module and gives most of the advantages of CDI without the draw backs.

It's very hardy too... Some water got into the loom plug, shorted between outlet and ground (500+ vdc), just blew a neat hole on the side of the plug and kept on chugging.

I use it in conjunction with a custom loom and splitfires.... absolutely no issues with spark yet.

send me a pm so i dont forgot but will ask my tuner if he feel like I should use it or not! At the end, he's the boss, he's the one whos tuning it.

Here's a copy/paste from haltech tech support regarding the use of HPI6 in conjoncture with CDI or kenne bell boost-a-spark:

The boost a spark or HKS twin power would be unnecessary with a unit like the Haltech HPI6. The Haltech HPI 6 is able to supply up to 15 amps of current through a standard inductive coil as long as the coil has the capacity for 15 amps of current. Most coils do not have this much potential, so the Haltech HPI is already providing the maximum spark energy that the coil will allow. Once you have reached the limit of the HPI6 unit, we usually suggest moving up to a CDI unit such as the M&W Ignition systems units that we stock.

So maybe the HPI6 is already overkill for a standard bnr32 ignition system, hence why the tech told me it wasnt necessary to use the HPI6 ?

If you already have a HPI6 then I would use it. It will make it easier to use some bigger coil packs later if you feel you need them. Essentially with the stock coil packs it will optimize current delivery...

If you need more than the factory style set up, 450kw+ sort of territory then you go two ways:

- CDI for a race car

- Twin spark or aftermarket ign (non cdi) what ever you like.

As a side note, I'd stay away from a 'boost-a-spark'. There is an excellent local supplier for a very similar product.

Please educate me.. tell me more ? From haltech post, any cdi or even the boost-a-spark ( which is not a cdi) was not needed either and going LS2 is more complicated tha some people tend to say it. ( need to fab bracket, make sur it clear strut bar, etc.

I have new igniter harness, new oem coilpack and HPI6, I think this will be enought for my -5s setup but for a long time I was interesting in adding the BAS to my system ( before I bought the hpi6/haltech ecu)

ICE make a really nice 16V supply module that I have used with stock ign set ups on pre-(internal ignitor coil pack) rb's. I think this would be a valuable and reasonably inexpensive mod later if you need a little more kick using stock style set up.

With a new harness, new coil packs and -5's you'll be fine. Just use the HPI 6.... happy days.

      Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.

      J50 clock date suddenly reset to January 1

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
