Hey guys, if i were to change my coilpacks to some new spitfires.....would this mean i could run my sparkies at 1.1mm gap, and still have no missing on 12psi?

Will i notice a good diffeence in power after going from .55mm gap???how does gapping affect performance???

........1.1 is crap, dont bother. the sparks u recommended is good .88 is da way to go ....

lol why bother i mean the cars were made for .8 mm so you'd get better performance if their gapped at that with spitfirezzzzzz :sorcerer:

put sparks in ( BCPR6es or wateva the code) is and if your car still dies ... go to repco get a DIY spark plug measuring tool then you can measure em up .....and clamp da gap together youurself ;-) and da wrench is 3 and a half turns.. look on da spark plug packet it tells u it...

and next answer: you saw how gapping affects performance!! KAAABOOOM DIEZ in the arsee... :pirate:

The only reason it dies in the ass is the coils cant provide enough charge to spark that distance properly. The bigger the gap the better the combustion and the more power/economy you will get. The biggest gap you can have with no misfire is the best option.

Get new coils and try 1.1, if you get absolutely no missing leave it. If you still do move down to a .8, I wouldn't say the car is made for any particular gap, its made to run the biggest gap possible. On a completely stock motor (7psi ?) I'm pretty sure 1.1 would be fine with the aged stock coils

If you look under your bonnet there is a peice of paper stuck to the lining, it states the gap to be 1.1mm. So the cars were made for 1.1mm gap. But you up boost, power, etc. then everything else needs to change.

Splitfires, 0.8mm gap and you shouldn't have any issues.

do the coils have to be fuly removed to tape em up? if so, the 2 screws on most of my coils to remove them are f&cked, what will help in easing them up?some crc? i dont want to ruin the thread on them:(

Notice the hex shape on the outside? use a socket :(

They are usually pretty damn tight if they havent been removed in a while, doubt you could get most of them out without ruining them if you used a screwdriver.

Yes you do have to remove them, I dont really see how you would patch them up otherwise.

you can bore the guy out next to you later how combustion works after u thrash him...

Hah, boring you are we? :(

I'm not sure how much of a difference it would make but its worth trying the bigger gap first.

Just remember, running tape around the coils should only be a temp solution! and they may just be worn so tape will have no affect! Like mine!

Some of the older coilpacks have a metal rim around them instead of the 4 screw holes. There is about a 1mm gap between this and the coil. If this is the case its almost impossible to tape inbetween this gap and it will arc to the alloy holder instead. In this gase you need to fill the gap with araldite or some sort of high temp epoxy.

i have an r33 gtst '94 coupe, will this have the older style coilpacks???

regards

No idea, I only just noticed this then when looking at that thread, mine were the older type and epoxy/tape didnt fix mine so Ive got splitfires on the way but it has worked for alot of people.

what type of electrical tape works best???, i tried wrapping coils with CHEAP tape, and only wrapped with one layer of it, and its still missing. Before i go ahead and spend 550 on some coilpacks, im going to have another go.

One other thing, if i get new coils, would that mean i can run 10psi on 1.1mm gapped bcpr6es plugs?

Few things i noticed,......, my new plugs were already all pregapped to .8mm, and all my old plugs were gapped at around .65mm.....would i have lost power because of such a low gap prior(i never had any missing with the low gap though)

How does lowering gap affect the engine?i mean excessive lowering, which my workshop done on my old sparkies which i heard is bad (.65mm on 10psi :huh:

if you threw the plugs in straight out of the box i can pretty much garentee they will be gapped at 1.1 or atleast thats what ngk or champion or whatever was aiming for. there gaps are probably realisticly all over the place,

I always gap my plugs to .8 but if i wanted 1.1 ide still regap/check them myself and not just throw them in straight out of the box.

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 馃
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
