    "cheap Fix" For Coil Breakdown / Misfire - Oem Or After Market

    in General Maintenance

    Posted · Edited by 85URE

    I did the exact same thing a few months ago with a drill and a jigsaw... came out ok, but these look so nice :)

    About 5 weeks ago a coil pack still failed when the car got really hot.

    Thanks mate :)

    If you are still having troubles I read that some people don't run the 2nd, 3rd, 5th and 6th bolt as those bolt heads are

    right next to some of your packs and the bolt can then provide another short path to earth, or they

    uses a large heat shrink (with glue) that covers up the stem and also seals onto the bottom of the coil pack covering

    the join to the stem where they usually leak from.

    All that said, failing packs will get worse over time, just depends at what stage each persons packs are up to.

    Missfire Boost@4500-5500 RPM - The Answer! (for me at least!)

    Guess that depends on each persons situation, both financially and physically.

    Every coil pack breaks down over time, at this point in time my problem was the coil packs earthing out,

    By installing the plates, at a quarter of the cost vs new packs, it did remove my problem.

    also allowing better cooling for the packs as the alloy brackets transfer more heat that is responsible for destroying them.

    I was having trouble with my R33 breaking down but only when I tried to run high boost (24 psi)

    Running at 12 psi it was smooth and faultless so I changed plugs, fuel filter and a few other things

    but nothing worked so I took it to Gavin wood and he said the coil packs were more than likely at fault.

    Rather then shelling out and purchasing another set of coils OR gaping my plugs down from 1.1mm to .6mm

    I did some more research and found some people in the UK were making up Acetal plates for mounting their

    coils too and this was solving a range of problems for people.

    The theory is that when your coils fail they are finding the easiest path to earth for the spark to travel OR when you

    are running boost over 1 bar the spark can be "blown out" basically so the simple fix is to get more powerful coils

    BUT

    If you think harder about the problem and rather than resorting to fixing a short with "more power" to make up for it,

    actually remove the path the short is going to take and you will find all your power will now go straight into your plug!!

    From the minute I started the car even driving round on 12 psi it felt so much crisper and more responsive,

    but the proof was being able to run 24 psi again revving clean and clear right to limiter.

    Acetal or Polyoxymethylene, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability.

    All you have to do is trace your alloy ones onto the Acetal plate and you can then cut them out with a jigsaw and tap the holes.

    I made mine in house and would consider making up a run of these should people not wish to stuff around making their own

    and would rather to just purchase them.

    Hope this gives you guys another option to try at home when trying to sort out your misfires.

    Don't forget you can always use heat shrink down the "shaft" to the plug,

    and/OR make up a set of Acetal coil plates - can't give this mod enough praise!!

    I had a problem with misfiring but ONLY under full boost, 24psi, (12psi was fine)

    turned out my coil packs were shorting to earth so I made up some Acetal

    mounting plates and the miss is GONE, car has never run smoother!!

    I got the idea from an overseas forum where this fix was solving heaps of problems for people.

    I was actually thinking of making some more up If people might be interested in purchasing them?

    EDIT: All sorted, thanks for your interest

    Hi,

    Iv been searching for a TS (top secret) front bar for a R34 GTR for the last 3 weeks

    and i am yet to find one ANYWHERE!!

    I have received a GTT bar when i have asked for a GTR,

    and then EVERY single supplier iv chased there after have claimed they carry this bar,

    ie: advertising them on their websites

    only to tell me once i call them that they have none in stock untill next year!!!

    Can anyone tell me ANYWHERE i can buy either the TS or the VSP front bar for a R34 GTR.

    post-22943-1221722815_thumb.jpgpost-22943-1221722825_thumb.jpg

    ........ R34 GTR TS .................. R34 GTR VSP........

    thanks

    Mark
