Hey guys i have a R33 GTST and i installed a Z tune style bonnet on there and today it was pissing down with rain and i think that some water has go into the spark plug hole because its sounding like a WRX and just keeps misfiring? so im just wondering if i take off the spark plug cover and clean up all the water will the car run back to normal? would anything happen to the spark plugs?

Cheers

water wont get in the spark plug hole unless youre spark plug wasn't in properly... it could have got down and shattered the ceramic on the spark plug... but i doubt it... could be a a spark plug has gone (through use) or even could have got water in the air intake... is your filter inclosed? and is there a vent near it??

Yep its the vented bonnet "I got rained on and my coil pack cover isn't water tight" sound...

The hard part is getting the water out, I used a long piece of clear hose and gravity to drain the water...

Afterwards make sure the rubber seal on the coil pack cover is on straight and sealing properly, I leave the back of the coil pack cover loose to let heat out so my splitfires don't get overheated.

The water will evaporate but its not advisable to do it that way...

hmmm well its not in the hole im just saying it could be sitting like aroudn the spark plug? mmm perhaps some CRC and alot of rags to drain the water :glare: mmm it doens't have a vent for the air filter part but yeah ill see tomorow perhaps its time to invest in a new filter :D

what new filter, the water is nowhere near your air intake? An I missing something?

its sitting around your spark plugs and making them arc...

The ztune style bonnet has vents directly above the coil pack cover, thus why making sure your coil pack cover seals are installed correctly will resolve the issue for the future...

as long as the coil pack cover is sealed there is no problem... I too have a vented bonnet and had the same problem at first since I didn't run a coil pack cover at all... sealed it and all is good...

Tighten the screws I believe is what he means.. Otherwise silicone would work but surface would have to be cleaned extremely well (if you wanted more protection) Alternatively find some silicone boost hose split it up one side and slide it down the sides of the cover and glue together at each end and screw down should do i decent job if you get it in right

Probably worth taking it all out for a day to let it dry out i think you can bugger your coil packs getting them wet just like most electrical things they can get wet but its the corrosion that will kill them in the end!

My GTR has a vented bonnet also, When it rains it scares the hell out of me.

I have no gargage so i put a car cover over my car, I am sort of lucky the water hit's the fan so it's really not going on the top of my engine lucky because i have no engine covers.

water can get in the electrical plugs( cas connector) and cause the same problem. but sounds like u need new plugs or coil packs.. most ppl dont run the coil pack cover to stop them getting as hot.. but then if u dont, u get the problem with water.. but thats easily fixed compared to the price of a coil pack

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
