Iv been scrambling through the forums to find my best turbo choice for my R33.

Im running a forged RB25 with pon cams mild head work N1 oil pump FMIC and other supporting mods like full exhaust head gasket bearings coil packs AFM apexi ECU etc.

I had a high mount with a T04z greedy FF plenum and was making 653HP at the rears untill i got flagged into a RBT and ended up with a canary and living 7 hours away from the closest emissions testing center makes is hard to engineer as i work 6 days a week aswell so im toning it down abit to make it streetable with no red and blue lights behind me.

Iv sold the FF plenum and the hotside setup but im wanting opinions on a smaller turbo choice but i still want awesome responce and i still want power up untill the 8k RPM..

Here is my choices im choosing from at the moment.

-GTX3071r

-Hiflow my STD turbo

-GTX3582r

What do you guys think of these choices and any other turbo options u guys think is suitable as im after about 250-300rwKW and trying to keep the engine looking standard as iv already been pulled over 3 times in a month since its bsck on the road lol.

Read the thread and I'm sure 100% of peeps with one is over the moon with theirs.

Not quite, but who's counting...

Unfortunately bagging a forum trader's product is not allowed no matter how many times you have issues with it, or how you are treated, so you will likely only see one side on here Grant.

You are missing the GTX3076 there, I think the 71 may drop off a little in the top end, but a .82 rear on a 76 might be perfect, especially if you externally gate the turbo or stock manifold.

Are you planning to run e85? That would change things... The GTX3076 is good for 400kw on e85.

That's why I said 100% :P

Thanks scotty ill look into it.. i didnt look at it but i will check it out now..

My thoughts are the 3582r will be to laggy downlow and the 3076 sound good

What im aiming for is a response and power through to about 8k rpm.. the KW ill be happy with 250 even but im wanting 600-700nm out of it as iv had big HP cars but they are useless.. can only go 100kph and il love to leave anything behind up to the 200kph..

I've been a trader on this forum for 7 years and been recommended by many for good reasons. We don't compete on this forum through bagging out other traders.

For around 250rwkws application, high flow of factory turbocharger will do the job, it bolt up to factory spot, looks standard and that is more responsive then any of the GT30 or GT35 options. We have a big evaluation and discussion thread which covering different aspects of RB25det modifications as well as development in Rb turbochargers. Thread is indexed on page 1, and packed with member's results, feedbacks and options.

We move a good number of Garrett turbos, and will be able to supply at a very competitive pricing. For any of the GTX range apart from GTX3071 is not recommended as a responsive option or to run internal gate with. You are welcome to give us a call or send in a PM for recommendations and latest pricing.

Also missing the GTX3576 ... spool/response is nearly-ish the same as a GTX3076 but it will make more up top.

To find good comparisons, look on the NAISOC forums... heaps of testing back to back on GTX3076 vs. GTX3576

I'm using Hypergear's SS2 in a .82 rear with a Nissan front cover making 297rwkws at 20psi full boost by 3800rpm. factory appearance, and completely bolt on.

Does this require a spacer plate between the flange and do standard water lines bolt up?

    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
    • It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!      
    • Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
