Drax240z Posted February 1, 2005 Share Posted February 1, 2005 I have a chance to buy one of these with 67,000km relatively cheap. Just wondering if anyone has any info on them. I know it's a T3 flange, ceramic turbine, plastic compressor, and it's ball bearing. Looking for something that will be more reponsive than the stock T3 and maybe this is it! Anyone know exhaust A/R, flow rates, etc? I know these don't like to be pushed past 15psi. Quote Link to comment Share on other sites More sharing options...

yo2001 Posted February 1, 2005 Share Posted February 1, 2005 I think it was T28 ceramic BB. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted February 1, 2005 Share Posted February 1, 2005 all n1s have steel wheels, although only r34 have ball bearings. http://www.skylinesaustralia.com/forums/showthread.php?t=62632 Quote Link to comment Share on other sites More sharing options...
Drax240z Posted February 2, 2005 Author Share Posted February 2, 2005 Aren't N1's the RB26DETT turbos? Someone here must know what the RB25DET came with for a turbo.... even if you can confirm any of the info I've posted that would be helpful, it's hard to find much on the net about this turbo.

Guest Aguyandaredhead Posted February 3, 2005 Share Posted February 3, 2005 OK in short the R33 Rb25det was a Nissan casting that was an offshoot of the T28 that we know Garrett made. It is a Ball bearing unit and it is not a plastic comp wheel. It is a ceramic Wheel and it is safe to spin up to 12psi daily, I would even say to 14psi on very rare occasion with short pulls. The wheel is not the weak link it is the glue (epox) that holds it on that gives way under the heat. This being said it is a fairly fast spool up with less rotational mass than a turbo with the steel wheel, but just not as tolerant of extreme heat.. Hope this helps..

spiff Posted September 22, 2013 Share Posted September 22, 2013 Just like the OP I have a chance of buying a stock rb25det turbo, slightly used, relatively cheap. Should I jump on it? Would it provide a nice upgrade compared to the stock L28ET turbo? (I'm thinking it does) Quote Link to comment Share on other sites More sharing options...
beaniam Posted March 16, 2014 Share Posted March 16, 2014 A little late to see this but I am currently running one of these turbos. It's great under 12psi. Spool is nearly instant. I'm afraid of leaving it at 14psi for risk of the glue going out. I'll probably be going with a holset variant and putting this up for sale in a little while. I want more boost!

spiff Posted March 17, 2014 Share Posted March 17, 2014 Thanks, I bought it but haven't installed it yet. Have you done anything with fueling to run it at 12 psi? Quote Link to comment Share on other sites More sharing options...
