Hello.

i have a r32 gtr, and a have some little misfire in high rev.  I want to buy splitfire ignition system + do luck harness.

But i have a simple question for australian people, because in France, i have not a clear answer :

if i install a r34 ignition system, can i remove the ampli (power transistor) ?

thanks. 

(I'll do a quick research, but hard to find answer with my limited english)

Yes, you can change from dumb coils that need the ignitor box to coils that each have an ignitor built in.  You will obviously need the appropriate harness, and you will still have to adapt it to the R32 harness, because the power and the triggering wiring are all based around the ignitor.  The new coilpack harness will not simply connect to the old body-side ignition harness and just work.

Thanks for Quick answer. 

Is the r34 coil have an ignitor built in ?

for the harness, i simply think to buy the r34 do luck harness, replace and wiring the r34 connector with r32 connector, and remove my ignitor box (ampli). Is there something that i forget ? Is it more complicated than that ?

I may have to do a quick back-pedal here.  I was allowing what I know to be true for the differences between R32 (RB20) and R34 (RB25Neo) coils to pollute my thinking on the RB26 coils.  I put my hand up and declare that I do not know for sure what the situation is with R34 26 coils/igniters.  But if there is no change (ie, they still use an external igniter) then, no, you can't throw the igniter away.  If they did switch to internal igniters, then my first post is correct.

I thought you were trying to get rid of the Ignitor?

sure.

That's why i want to install R34 coils. A friend with a BNR34 confirms me he have not ignitor in his engine bay with oem coils.

It appears that the Splitfire DIS5 that suit Neo RB25s are also claimed to be correct for R34 RB26s.

That would make more sense than Nissan just sticking with the shitty old coils they used on the 32 & 33 GTRs, which were the same as the RB20s.

Bnr 34 coils have inbuilt ignitor and mount the same as r32/r33 coils ie the 2x 3 aluminum x shape brackets, they aren't the same as r34 neo coils mounting wise.

The bnr34 coils use the same plug/wiring sequence as r35/vq coils.

I've fitted neo coils to a vh45 eliminating the ignitor from each bank. Was pretty straight forward, I changed the pin location on back of plugs and added a +ve to each or from memory. Was a while ago.

Thanks mates. 

@Anonymouse : thanks for the link. But someone said me r35 coils need to remap the rb. 

@Griffin & @GTSBoy : thank you. So, i will buy the splitfire bnr34 coils, with the doluck r34 harness. I'll let you know in a few weeks.

I found these on ebay and was thinking òf using this rather than relying on the igniter. What do you think GTS BOY?? Also will I need to return after I install??Screenshot_20200405-095623_eBay.thumb.jpg.b9e69862e9b0ba1be50def31920cc6f4.jpg

The Kudos motorsport kit is the go for what you're talking about without going the R35 coils. As mentioned retune not required, although if you have the ability in your ecu there is a slight reduction in dwell time compared to the 32/33 gtr coils. Would probably ok not to adjust but they are different FYI. Also as mentioned that wiring specialties coil harness also suits the R35 coils if the 34s don't have enough punch for you.

That's my 1993 r33r impul, with 2.6 conversion and pushing well over 500hp. I know the igniter will fail again sooner or later so I will go ahead in the very near future with the igniter coil packs. Also I would like to change the pulley to a serpentine set up. Anyone done that and got any idea if there's a kit available?? I also need to chase up a heat shield for the air filter, if i could get cooler air in should help performance too surely??received_733672663834867.thumb.jpeg.a992d2ed1801b52ffcbbf23d5f6558c9.jpegResized_20161015_085040001_3771_1572238889372.thumb.jpeg.483614ec96a48f0864faebc834ac1a31.jpeg

Also can you buy a pinion/ driveshaft bearing and seal kit for my abs locker diff r33??

Cheers for your advice and I think it will be a more reliable system. Whenever the engine sounds not quite right I always think not another igniter! I was lucky last time just a fouled plug!!!

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
