I have had lots of input but no one can confirm if my R34 Vspec II Std turbo's do or do not have steel wheels. If anyone can confirm this or if you have access to nissan statistics please let me know.

1.6 bar should work it out for you

car still running steel wheels if you need new turbos then ceramic

lol

Will this theory also work for my 32? Is this a tried and true formula or purely speculation?

i think so.

they are ball bearing though while all R33 & 32 are not

No actually all the factory run of the mill gtr turbo's (including R32 & R33) are ball bearing and have ceramic exhaust wheels, the R32 and R33 N1 / group A turbos are however non ball bearing but have the metal exhaust wheels. The R34 N1 turbo's are both ball bearing and have metal exhaust wheels.

Rev,

Thanks for yor input, but I have to challenge the Ball Bearing part. I have had my R33 GTR turbo's re-built by garret and I have a set sitting right in front of me, and they are not ball bearing, they are brush roller bearings (I think thats what they call them).

But thanks for the info on the R34.

Do a search for a link to the factory specs on the turbo's. You will find that with exception to the N1's the stockers are all ballbearing.

The performance exceptions as follows:

BNR32 (NISMO)......Serial No. 14411-06U00 (F/M273 deg. plain thrust bearing centre)

T04B Compressor with a 0.42 A/R and 62T

T25 Turbine with a 0.64 A/R and CD79

BCNR33 (N1)......Serial No. 14411-24U10 (F/M360 deg. plain thrust bearing centre)

T3 Compressor with a 0.42 A/R and 55T

T25 Turbine with a 0.64 A/R and 62T

BNR34 ......Serial No. 14411-AA300 (Ball bearing centre)

C100 Compressor with a 0.53 A/R and 50T

T25 Turbine with a 0.48 A/R and 62T

BNR34 (N1)......Serial No. 14411-AA401 (Ball bearing centre)

BNR34 (N1)......Serial No. 14411-AA402 (Ball bearing centre)

BNR34 (N1)......Serial No. 14411-AA403 (Ball bearing centre)

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      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)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      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

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      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

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      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.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      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.
