So I took my R32 GTR out to Wakefield for the first time today. Towards the end of the second session, i shifted down to second and hit the gas, and turbos stopped boosting. The car was running completely fine, idling properly, and running like normal, except there was no boost pressure whatsoever. I can still hear the turbos spooling when revving over 3500 rpm, but again no pressure. A couple of guys came and had a look but couldn't find a problem in the engine bay. I'm not sure where to start looking, what do you guys think?

Cheers!

You can hear a turbo...but not the other...you have spat a turbine (exhaust) wheel my friend.

upgrade time :ninja:

the above two suggestions are incorrect due to the following...

a split/leaking boost control line would do the opposite and actually give you more boost as the pressure to the actuators would be lower and make them not operate at the desired boost level.

a blown intercooler hose/pipe would give you an overly rich condition and have black fuel smoke pouring out the exhaust and make it nigh impossible to rev over 3500rpm.

Thanks for that guys I think you may be right. there was definitely no black smoke either. We spoke to the guys at Eagle and Raymond and they seem to think the turbines have cracked. Time for an upgrade indeed.

They suggested reconditioned N1s, what do you guys think?

2860-7's or -5's depending on your power goal

Well i'm mainly doing trackwork so i'm looking for response rather than big HP.

Hopefully its not the turbos, don't want to fork out the cash just yet and i'm pretty happy with the job they are doing so far (other than not working obviously :)). I'll let you guys know what I find.

Cheers!

Ok guys just got it back from the mechanics. Turns out it was the turbos, but also the inlet manifold gaskets needed replacing, so I had that done, but am yet to make a decision about the turbos.

I've been told to go for ball-bearing N1's, or change the setup to single turbo.

For a reliable weekend circuit car, what would you recommend?

Hey guys, I decided to stick with the twin turbo setup. I'm about to put down an order for 2860-7's, and I just wanted to get a few facts straight.

These are bolt-ons correct?

How much HP will they be good for on an engine with stock internals?

What else would i need to get the full capacity out of them?

And when comparing the 2860-7's or -5's, its my understanding that the -7s spool up quicker with less lag (more responsive), so what are -5s good for?

As I said before, i'm mainly after response, so would this be the way to go?

    • 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)
