Help! R34 N1?

[PSIKO]

Hi !

Could anyone tell me what turbo this is.

I bought it as a R34 N1 turbo though not sure if it is or not.

I have done a HEAP of searching and have found that 34 N1 turbos should have :

0.60 front

0.64 rear

9 blade rear wheel

No markings on the front compressor housing

These turbos have:

0.42 front

0.64 rear

9 blade rear wheel

No markings on front housing

Does this turbo look like an R34 N1 ?

There is no plaque

On the rear it has written:

0.64 428-2 TR7093

Any help appreciated !!!

My bet is 32 or 33 N1 turbos

[PSIKO]

so definitely not R34 N1 ?

what about the lack of markings on the compressor cover?

but then again I guess unfortunately the 0.42 a/r tells the whole story doesn't it :flamed:

[PSIKO]

Ok I will let you know these turbos are R34 N1 turbine because of the following:

1. it has no markings on front compressor while nismo turbos do ie a/r .60

2. it has nine blades at the back while r32 nismo turbs have 12

3. if it spins really, really, really easily than that means its a ball bearing turbo, while r32 nismo turbos are not.

[PSIKO]

Yeah those three points are valid

BUT

It has a compressor A/R of 0.42 instead of the 0.60 A/r

Apparently all R34 N1 turbos have a compressor A/R of 0.60

The A/R I can see written inside the "tube" part of the compressor housing (sorry not sure of the name of that particular bit of the turbo but where the compressed air goes out of the turbo and off to the intercooler).

OK guys

I ?think? I have similar turbos currently fitted to my R32 GTR (only just)

Part Number is : 14411-AA403 (both turbos did have the plaque)

Which according to Nissan are series 3 R34 N1s – with SS internals and BB rollers. They also have 9 blades

BUT

Mine also have a small separator between the rear turbine wheel and the waste gate (which yours do not seem to have – tho the picture is a little fizzy)

I have only just had them fitted and have not had the chance to fire them up yet, so I can't tell you how they will go. I'm waiting for PCF + EBC to be fitted in a week or so.

I'm also fairly sure they are .42 A/R on the comp side (can't be sure and the pics I have do not show it) and they came off an R34 V-spec II AFAIK

I do have a SQ (silly question) Are Nismo and N1 the SAME thing?

My understanding is that there are N1 turbos and Nismo turbos – and only the Nismo turbos have the .60 compressor housing - but I could be making it all up

Cheers to banzai for confirming that they are 34N1s

They are ball bearing due to the bolts on the turbine housing

Apparently some 34N1 turbos have 0.42 front covers and some have 0.60

R34N1 turbos

compressor 0.60a/r

47.22mm

turbine 0.64a/r

46.95mm

Indeed they are the specs of the 34N1s that UAS are selling

A search of the forum will reveal that there are many types of 34N1, and I have now found that they came out in a 0.42 compressor as well as a 0.60 A/R

Pete you got the ones with the 0.60 compressor which are the ones I was after, so I'm selling these and will try and get some with the larger compressor housing. Either that or I'm also working on the possibility of swapping the comp covers over to the larger housing.

EDIT: have found a pair of 0.60 A/R covers so will see if these fit once they arrive. in the meantime have taken off the market. if they dont fit i'll have to put them up for sale again. here's hoping!!

yeah no worry ,i lose track of whos who no here sometimes, i have got a another guy down this way chasing the r34n1 aswell

i'm concidering see if there any interest in group buy

as i was talking to turbotec yesterday and

there off the street price is ~$2325ea

if we get a group buy going ~$2000ea

not bad for such a great turbo(the turbos that won targa this year i believe)

Flicking through an old mag and they made mention of N1 turbos and NISMO Group A turbos. Both available through Nissan apparently.

Saying the N1s were same size as standard with better flow capabilities obviously and that the Group A turbos were identified by there larger 0.6 compressor housing. Maybe this is the confusion or group A turbos are something different again?
