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.

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
