Well I've just pulled the turbo off my GTT which is 7/99 series one and put it next to one from an R33 series one.

First thing is that on the side of the compressor covers the R33 one has 45 v 1 whereas the R34 one has 45 v 4 on it.

The compressor covers appear identical.

Now I know this goes contrary to popular opinion but the R34 compressor wheel appears to be metal just like the R33 one.

On the R33 compressor side outlet there is a 1 cast on the outside and a 3 printed on the inside. On the R34 these are both 2's.

On the exhaust housing on the r33 one is cast 307B 2IU, a bit further round there is an 8.. The equivalent on the R34 one is 527A OP6 and further round a 9.

On the other side of the exhaust housing we have F 2IU (R33) and E OP6 (R34).

One thing that is definitely noticable but a bit hard to measure is that the R34 exhaust housing is bigger than the other one. Also the entry port from the manifold is wider on the R34 by about 1mm or so in both directions.

Anyway, I just thought I'd post this for general information. Perhaps people can add their knowledge to it. Maybe if someone has an R33 series 2 turbo or R32 one off the car in front of them they could post the equivalent details.

What kind of sound does it make when you tap it with your fingernail?

I had assumed my R34 turbo was plastic/nylon/whatever till I did this and it sounded tinny so I dug out the old one to check and they seem to be the same. They also look the same as the pic you have posted.

Hmm, What does yours say, 45v????

Yeah, we should link this to the Stock Boost for R34 thread. The R34 compressor wheel is nylon plastic crap and isnt as strong as the 33.

But as I also mentioned, some series 2's came with a steel wheel but, as soon as i find solid evidence, ill post.

Hmm, it's looking like the other turbo I have is series 2 R33. Can one of you R33 owners look at that link I posted above and tell if the car is series one or two. That's the car this turbo came from.

Anyone want to post a pic of the turbo side on so we can see the size of the exhaust housing?

This 45v1.2.3. thing is weird.

Abo i'm 95% sure that's a SII R33.

* Bonnet lips down over the center grill.

* Headlights (im pretty sure on this part).

* The panel at the rear between the bottom of the boot and the top-middle of the bumper (S1 is a clear plastic from memory).

"14411-AB000"

s3 is metal with twin blade, made by garrett instead of nissan, bigger than s2

basicly, If your NEO engine cover W/O RED wording...that's S2 or S3

more detail about difference between s1,2,3 (japanese)

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
