Thanks Jon, it turns out that its a 6 bolt on the turbine housing.  It came off an RB25det that the guy had put in his silvia.  After one week of driving it around he put on a HUGE turbonetics item on it...................I've never seen a turbo so big!  It has a 4 inch inducer on it, anyway its in good nick with absoulutely no play in the turbine shaft, no signs of coking and no signs of oil leaks.  It had only done          53 000kays and it had never had any bleed devices on it so its probably never been run above 8psi.  Best thing was that I only paid 500 bucks for the thing!  One question I have though is where do they take the signal for the wastegate from?  It doesn't have anything drilled or tapped in the compressor housing like most turbos I've seen, would it be on from the intake manifold?
 
Thanks Jon, Errol, Heath, Andrew etc, etc for the advice.

The silver rocker cover RB20det's come with a Ball Bearing T28, ball bearings are recognised by the 6 bolts holding the housing rather than 5.
 
15psi should be heaps from that turbo, ample for the Z.

Yeah, I've been told that about limiting the boost.  I'm pretty sure it will be big enough for what I want and since is ball bearing it should spool up pretty easily.  Thanks for the advice
