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.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
