Hey guys,

Well as one of my turbos died last week I've considered an upgrade....

Someone has offered to sell me these turbos:

Group A N1.....the code is something like 14411-06U-00

R34 V Spec II

AR 60-64

5 degree cut rear wheel

360 degree thrust bearing

Steel wheels

Is there some way i can verify that they are of an R34 VSPEC II?

They've done low kms and look to be in great nick.

He's saying he wants $1000 bux.......good price?

Also, how will installing these turbos on my standard R32 GTR improve performance? It has nothing, except for Apexi airfilters and a full exhaust system.

Cheers,

Ali

From what i understand the N1 turbo's have a slightley larger turbine blade than stock giveing a small power improvement for the same rough amount of boost. Of course the main bennefit is that the turbo blades are steel, instead of the stock ceramic ones. This means better reliability and the ability to run more boost than the stock turbos.

The N1 turbo's were designed by Nismo for competition use, offering the best trade in their opinion between response and power. Their the best option for the price for track GTR's, road/race GTR's and fast street GTR's. The spool up time is almost identical to stock, but you can also run boost levels up to 1.3-1.5 bar without fear, unlike the stock ceramic ones.

With the appropriate other mods, Exhaust/IC/Fuel System/ECU and 1.4Bar ive seen a few GTR's make anything between 260KW-330KW at the wheels, depending on tune and dyno.

For $1000 id say they were a good buy.

i wont waste your time on this turbos personally

the turbos you want BRAND NEW are the garret replacements 707160-5

racepec are selling them for around $2400 new

the reason i say dont waste your time are the r34 vspec turbos are still ceramic turbine wheels and still fail and if they fail under the wrong conditions will take the motor with them (like the last r34 i built) and the group "a" are laggy but strong

the gt2560r 707160-5 i use in a light modify combo ,generate well over 500rwhp with basically no lag what so ever (have done a number of these combos now)

so for a little more money now you will never regret it later.

OK bit of confusion, the code hes given matches R32 nismo code, but he reckons that the paperwork is in fact of an R34? Anyways....

Thanks for the feedback guys!

Hopefully i get the turbos sometime today....will take pics when i get them!

Cheers

He was asking about R34 N1 turbos, but I agree with your comment on the Vspec turbos. Did a conversion on the RB25DET with a pair and the front turbine let go at 5psi. Damned ceramic crap.

The R34N1's use inconel instead of steel on the turbine wheel.

Still seems a good price for N1 turbos. The advantage of the R34 N1 is the roller bearing and the inconel turbine.

Just for interest, my turbos are steel wheeled stockies on the GTR, and they produce 260rwkw at 1bar with the stock computer so the N1 should do a bit better. While it's apart why not get some decent dumps and a set of UAS extrude honed manifolds? Of course it's more cash but the time is right.

this turbo 100% not R34 N1 turbo,couse R34 N1 turbo got separate wagste at back of turbo and R34 V-spec2 use same turbo as R34GTR,no any different.hope it wil help.

the one you got more than likely are R32 N1.not Nismo turbo.

couse Nismo turbo's code are RR580 or RR581.

just to ad to the confusion

How much extra dosh are we talking, for the dumpa dn UAS extrude honed manifolds? How will they improve performance? Sorry for the basic quiestions, but although i've owned a whole stack of imports, i really haven't gone all gunz blazing in modifying them......

LoL....that pic with the code saying its nismo has confused me now......so are they normal n1 or nismo n1.....or what not.....:S

I thiink they were called Nismo on the R32.

Take a look at www.nismo.com.au for the UAS stuff. JP is on the forum here as boosted zed and has done some posts on the extrude honed manifolds.

Thanks for the help mate,

appreciate it.

Alright cool....

still no word on improvement on performance?

Please search mate.

The topic of GTR N1 turbo's comes up all the time.

and the usual response is they arent as good as a set of HKS 2530's which are better in every area.

The N1's arent the best turbo. 32 N1's (as it seems these are) are a cheap upgrade, and will get you more power.

But get into a car with a decent set of turbos and you'll cry everytime you drive yours for overlooking it

I tried searching.

The search engine kept telling me something along the lines of "less than four characters" so i can search......that ruled out N1 and GTR. Leaving...turbos. LoL

yeah agree that the HKS turbos are better, but I'm just chucking these on as the budget option, until Jan, when I will sell the car.

    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
