ok so it wasmis firing the other day and i made a thread about it. i changed my spark plugs. now it doesnt want to boost really. like it does sort of i can here the turbo spooling but its very resticted and stuggles to rev over 4000 revs especially in second gear upwards. ANNNNNNd its still mis firing. wtf so its actually worse now because b4 i could rev thru the rev range but not at full throttle now i cant get thru there at all no matter what it just starts mis firing. i checked my coil packs and the seemed all good. brand new plugs. could it be a tuning issue? some on has to of had this problem b4

did it make any difference if you put the old ones back in ? might be a dodge plug or not in properly , but prob be more likely to be coil packs. How old is the car and kms ? but i'd be trying the old plugs in again before you fork out the $600 for new coils

yeah dude its either coil packs or spark plug ive had 3 skylines and i had both probs, with the spark plugs change the spark plug gap from 1.05 to 0.85 or 0.80 car stop mis firing and the other is coil pack its a common prob with skylines on the bottom of the coil pack were the rubber bits conect they sometimes get the smallest crack u can bearly see it what i did instead of forking out 600 bucks for coil packs was got a rubber gasket glue and smeard it all over the bottom half of the coil pack this prevent the spark from going out the crack on to the tapper cover . send me a msg on how u went with that

does it start to miss fire when it hits boost and then goes alright near rev limiter, trust me u can bearly see the crack if its coil packs, the other thing is that it could be shit fuel i bought some fuel in batemans bay and it was a independent shell station i whack some octane booster and then it ran alright.just a questoin did start to run crap after u filled it up and r u using 98 octane fuel

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
