Hi Guys

So ive searched and I can see that this topic has been beaten to death many times before , as the 7m's have gasket issues , the RB's seem to be prone to misfire and low revs

I bought my Skyline about 2 weeks ago , drives like a dream however when idling or waiting in traffic the revs seem to drop and the engine seems to misfire , the revs then pickup again but every now and then will drop and misfire.....

yes check AAC etc...but after i dropped 15k into my supra and worked on it by myself I promised not to touch a car(or at least my car) again...so im taking it to a professional.

Ive heard good things about Indy at IS Racing in Rockdale so i gave him a call , he seems to know a good deal about RB's

He then asked me what i petrol I use(told him premium 98) and then mentioned that RB's are known to drop revs and misfire from time to time because they are tuned for Japanese fuel but is now running on Australian fuel which is significantly different.

He said if im looking for silky smoothness (ie a "quiet engine , no taps etc) then i wont find this in an RB

I wanted him to take a look at it anyway so Im booked in at 11 tomorrow but just wanted to know what you guys thought of this....

Misfiring at low revs and revs dropping at idle because of the petrol we use is quite a big issue. My question is ,can any of you guys confirm this, is this a well known "RB fact"?

my car runs silky smooth and i run on e10....... (rb25det NEO @ 14psi stock turbo)

r33's have an issue with the aac getting really dirty and most people seem to flush them out or clean them.

i know of some people claiming to have problems in some of their skylines when running hi octane petrol, one guy says he has a perfectly stock r32gtr from japland and he has problems running 100octane and sais the car runs like shit and just spits and misfires, so he runs octane booster.

my 2 personal friends on the other hand, have both imported a r32gtr from japland 4 months ago, with everything stock besides the exhaust and the boost restrictor removed can run their cars perfectly on e10, 95oct,and 98oct.

so to be honest, i dont know what people have problems with.

checked ping. ive had no problems with pinging on e10. ethanol runs as good as it should. 95 i got more pinging than on e10.

why do people think e10 is shit petrol? we all know the properties of ethanol and the chemical structure. it is better than petrol

      Nah, they'll do it without a receipt, tell em roughly when it was, that it was cash, youll likely only get store credit, but that gets you some dollars towards the newer better shovel, or other item you need/want later.   Still take it back and have a crack at returning it.

      Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.

      That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!

      Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)

      Was that deliberate?
