Heya all, im fairly new to the skyline scene bought my R33 series2 GTST in Jan.

So im a little unsure about a popping noise comming from the bonnet when i put my foot down in boost.

It would be fine until about 3000rpm then pop until 4000 then sound fine againal the way until i had to change gear.

The bloke i bought it off also a memeber suggested that it could be the spark plugs as they had done about 20,000.

So i swapped them out yesterday, the old ones looked a little used but no damage and the tips were still there.

After the new plugs and an oil change i took it for a drive and seems to go fantastic again.

untill everynow and then i hear a slight pop, but only everynow and then. like 95% of the time i can put ma foot

down and be peferctly fine. The other 5% the dredded pop would be back although no where near as bad as before the plug change.

could it be the coil packs or what??

Any advice or suggestions would be greatly appreciated!!!

cheers.

Duffy

      Stolen white R33 GTST brisbane

      By Murray_Calavera · Posted

      I hate to say it, but this isn't a 'great length' to steal a car. The people that steal high value cars are very used to stealing cars from garages. It really isn't a complicated process, a lot of people leave their keys in very typical places (think bowl/rack by the front door). You break into the house, grab the key and off you go. So what, in about 1 minutes time they have taken the car?  Probably goes without saying that most of these cars being pinched in this manner are the higher end Audi/AMG/etc. It's the same process though regardless of whatever the car is.  If you're worried about this, keep your car out of sight. If no one knows its in the garage, no one is coming for it. Other things include if you have an aftermarket ECU, change a setting so the car won't start even with the keys, setup CCTV cameras that ping your phone on activation etc.  If you think it's hard to break into a house to grab the keys first, just picture the fire fighters coming to recuse someone from a burning house. It's what, 10 seconds to gain entry if that? Locks only help honest people stay honest.

      Yes but when you buy that Nissan/Ryco filter it comes in a Nissan box labelled as Nissan. In this case it was in an Aisin box. A heads up would have been nice. If I had received it in an Exedy box I wouldn't have a problem if that's what Exedy supplied. I don't really care as long as it does the job as well as the Exedy did. 8 years of 300+rwkw with a fair bit of abuse. Time will tell as always. I have a swirl pot thingy, constantly self bleeding. If it is air in there it will sort itself out soon enough.

      Being in South bris myself this concerns me that they went to these lengths.   Can I ask how hard is it to get to your garage? Like is it a garage at the front of the house close to the street, or you need to enter a fenced yard, and garage is out the back?

      The question is, when you bled the coolant, did you do so with the heater tap fully opened and heater on? If you haven't, you may have an air bubble in the heater core, double check your coolant level and overflow bottle.

      Yeah, but, it's like go and buy a Nissan filter. Nissan didn't make it, it's likely a Ryco etc.   You bought exedy, but "they didn't make" that specific part. Chances are, lots of actual exedy kits are, and have been, running aisin plates for ages.
