hey guys i'm having some issues with my ignition? it seems its not getting constant spark to the coilpacks on my rb25.

i've changed the ignition switch on the back of the barrel thinking that was the issue but the car started & ran fine till i drove out the drive way & started misfiring.

anyways is there anything else i can check to solve the issue?

replace ur sparkplugs.

sparkplugs when there on there way out do strange things. so first thing i would do is replace them because its probs the easiest and cheapest thing to replace

plugs are new, changed the AFM & CAS but still done it.

its acts like when you take the plug off the afm doesn't know what to do & runs shit or a boost leak but i've checked everything.

when is the misfiring happening??? its common that misfire happens on either full boost or at high rpm and thats when the coilpacks are starting to show that they need replacing.

all the time pretty much but when the car goes to idle it just stalls but if i keep the revs up like 1500-1700rpm it ok but i can still hear some kind of miss like its not sparking all the time...

i have changed the coils to after market ones & stock ones...

      yeah i agree paint match stops it from standing out so much, oh that's actually really good to know i was wondering if it would help with air flow now actually having an outlet in the bonnet. Will have to focus on ducting into and out of the radiator now to make the most of it.

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.

      Mistakes were made, my R34 Story

      I think it's bound to happen, you finally get it all perfect, and bam, something will happen. I took a while to get a Commodore rear quarter repaired where a P Plater clipped it. Two days after getting it back, Sarah wiped it out on a concrete pillar in an underground car park... This is why I take forever to repair them, it stretches how long until it gets bent again... 😛
