Are These Turbos N1 Or Factory Units?

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

      R34 GT-T cycling ABS pump

      The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.

      Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.

      Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using.

      There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.

      Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
