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.

      I hope it's actually possible. This is a write off in insurance world.

      Yup. 2-way with shallow ramp angles. Still works.

      That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain.

      OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
