^ what he said, and they have bush bearings and may well be old tech laggy wheels. Just go straight to -7s (aka R34 N1s) or -9s. Its a lot of work to change turbos and they make a big difference to how the motor runs, so if you skimp you'll regret it. Only other option would be to contact Hypergear to what he has to offer, but usually the cost of a proper rebuild/highflow is too close to the -7s so its just not worth it.

There's no difference between the blocks with respect to manifolds and mounting of turbos.

... do yourself a favor and find a mechanic with plenty of gtr/skyline experience before you buy anything!

That kit is neither N1 nor Nismo however is a waste your money. As with everything in life you get what you pay for. What you're after is a set of direct bolt-on Garrett GT2860R-7s (AKA R34 N1). If you'd like some advice or a quote drop me a line.

Hey Kudos,

I've got a 33 gtr. I was planning on upgrading the stock turbo's to -7's or possibly -9's though I noticed you have the 2871r-10's. Do you think these would be too small? I know there are plenty of threads on -5's vs 7's & 9's. Ultimately I'm trying to build the car for response and reliability. As guys who work on GTR's day in and out I was keen to know what you think the go would be??

Cheers

^ Do yourself a BIG favour - and research. -10s are the WORST possible selection you can make. Rubbish turbos, far too big.

Totally agree.

$200 turbo "upgrades" forget it - it's $2200 for a set of -9s or -7s or don't bother spending the money.

The N1 / bush journal setups are 1980s design, lack performance that has been well and truly superseded by more modern turbos and the extra response, power and performance is worth the money.

Turbos are the most important part, don't skimp on them or regret it forever.

Hi jnbR33, as R31Nismoid the GT2871R-10s aren't a great selection for the RB26 and for response the -7 or -9s are the best option with the -9s being the most popular these days by a country mile.

N1 'upgrades' don't really fit into the word 'upgrade' as it's almost a backward step using out-dated tech and the only average-at-best performance you get from them.

R34 N1s however, good upgrade - but they are a "-7" turbo anyway really, so just buy new and don't worry about it

depends really doesn't it? if you spend that money on the parts how much would 2 rebuilds cost to be installed and balanced by a turbo builder? $500-600? probably alot cheaper than 2 new turbo's?? i'm not saying you guys are wrong i'm just saying they might be a good option for someone on a budget.

Well the cost would be roughly $1000 (worst case of course) for two turbos by the time you buy the parts, send them off to be assembled/balanced.

So yeah it most certainly is cheaper... But they are soooo much laggier. We are talking laggier than a -5 turbo (capable of 400rwkw) but they will only make the power of a -9s (340rwkw).

That's not really a good option in anyones books to have all the lag without the power. Pretty hard to justify that being an 'upgrade'.

You'd be better off taking the chance with a 2nd hand set of -9s for $1200-$1400 and getting them inspected.

    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
