my addvice is to dump the factory coils for a set of vn/vp or mitsubishi ones

i fitted a set of vp coils to an rb30 about a week ago and it was running fine till the fuel pump packed up

and today a fitted a set of Mitsubishi Diamante v6 coils to my rb20 and it ran mint started much quicker and ran smoother more tourque and it runs the same gapped sparks as the rb coils

What sort of power/boost are you making on these after market coils?

If its near stock or still stock turbo on measly 15psi boost then we can't tell if it will work once the combustion pressures are considerably higher.

+ the non-stock look. For $520 delivered splitfires are the way to go.

where abouts can u get em for $520? Autobarn almost called the medics when they told me a new set of spitfires would cost over $1500 (cause i wasn't expecting more than $500~$600).

i got the exact same problem as you guys. gotta get this fixed up soon :)

$520.

Buy from Nengun (~2-3week wait), Perfectrun (~7day wait). (Japan)

You'd have to be silly to buy from auto barn and the likes. If you must buy a set in Aus grab a set from Slide. He sells them for $589 + postage.

I have r33 GTS4 NON-TURBO and got a misfire as well, what should be the spark plug gap for my one? is it still 0.8mm?

ive got no idea about the n/a's mate. do a search in naturally aspirated performance.

Pulled my coils out and they look brand new but i still have a miss!

your plugs look pretty shagged mate. close your gap to .8 and throw some new ones in.

does the rubber boot connecting to spark plug just pull off?

i had the missing problem 2 at 4500rpm and did the whole tape em up trick and u beauty, not a problem!

in the last couple of weeks, since we have had this hot weather, one coil seems 2 be playing up when the car is at peak operating temp

u will be driving, and all of a sudden it feels it drops a cylinder

u put ur foot flat 2 the floor and it clears it self up, and then when at normal revs u can hear the miss again

by looking at the coil there are a few hairline cracks but ive already taped them and still doin it when at normal operating temp?? any1 had this drama??

      Wheel Sizes & Offsets For Skylines

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
