Hi guys. Can anyone with some turbo knowledge maybe identify these turbos by comp housing numbers or exhaust wheel even as to whether they are factory R34 gtr units or -7 turbos? Seller claims to have paid $2500 from Japan and that they are rated at 450hp which leads me to believe they are -7 but unsure how to tell and whether they used a/r .53 comp housing? I thought -7/N1 used .60? :-/

Seller says the turbos are R34 GTR M-Spec, meaning they are just stock R34 GTR turbo's.

From the R34 GTR series, only the R34 GTR V-Spec N1 / V-Spec II N1 / V-Spec II Nur / M-Spec Nur ran N1 (Steel Internal) Turbo's.

Yeah I've asked for a pic of the serial number. Just thought it was strange that he said they are brand new, cost $2500 and are rated at 450hp but i was also under the impression m-spec turbos were just factory ceramic units. Surely someone wouldn't pay that for factory spec 34 turbos over 2860-7's or -5 for that matter

Yeah, depends how long ago the seller bought them... Back in the day, they could have costed that much... At the time when the seller bought them...

That's correct, 450HP is the max output according to the turbo chart but I wouldn't pump that much with ceramic turbines.

Yes, R34 M-Spec turbo's are just ceramic internals.

Could just be bad lighting in the photos, but they don't look brand new to me...

And to be honest, I would not bother spending $500 on stock R34 GTR turbo's, just buy new -7's.

Yes, exhaust wheel is ceramic, also the compressor hosuing on those turbos is A/R .53 & exhaust .48 Which is standard R34 GTR turbos.

-7 will have either A/R .42 or .60 compressor housing, and exhaust housing of A/R .64

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
