1G-GTE turbo differences

I am upgrading from a Gen2 to a Gen3 and the turbos on the new engine are stuffed. Can anyone confirm for me if the Gen3 turbo's have different housings than the earlier generations. Or is this just a rumour fabricated by people that have no idea???
I know that the wastegate actuators work at different pressures so I guess they are different, but is there any differences between the actual turbos.
Thanks

At a risk of being persecuted and told my search skills are rather crap... I failed to find anything on these forums regarding differences in the 1g turbo generations...
Sorry

my understanding of the differences was that they're in the engine management and injectors (and probably in the cams too). i think the big physical stuff is pretty much the same for series I to III.
to get the different boost, they would have had to change actuators as there's no electronic control of boost (nor does the ECU monitor MAP)
i think once they started development of the CT20 turbos, you ended up with differences over the life of the turbo hardware (e.g. CT 20 had steel then ceramic exhaust turbines)
aftermarket mods: I think there was a HKS kit for the twin CT12s and someone here recently sold a HKS single turbo kit for a 1G-GTE.

Is this pic here: http://members.optusnet.com.au/~nez_tony/mypic33.J PG
Is this the inlet pipe on one of the turbos? I'm going to measure my Blitz CT12's and I just want to make sure I'm measuring the right spot.

Great to see that you have tracked things down. I think that I did a post last year that went through all of the things that you have pointed out. My advice would be to use the gen 3 manifold as my 'seat of the pants' feeling is that it works better, bringing on boost a little earlier. I would have to remeasure again but I think that the gen 3 turbine is also bigger.

Frank, yep thats the inlet pipe.
Craig, yeah I am not too sure about the manifolds either. Externally they look the same. The Gen2 looks like it would be a better flowing path for number 4 but it also looks like thereisn't much room left for 5 and 6. I have left the Gen3 manifold on. The turbos bolt up fine.
On a brighter note, I actually got to drive the beast last night. It has been 10 weeks since the computer fried and it felt great to get back into a car with a bit of poke. The only problem is that I now remember that last thing I was thinking about before it died......"that diff is starting to make some funny noises....I must do something about a diff conversion"

Well after much stuffing around, I finally picked up the replacement turbo's.
They came off a yellow plug motor and fit the description given above for a grey plug engine. Spooky hey.
They seem to be in excellent condition with pretty much no shaft play, so they may have been replaced at some stage. Who knows....
I havn't checked the wastegate actuators yet, so I don't know what boost they will run without a bleed. It's an easy thing to change anyhow.
And the diff conversion will hopefully be finished soon. Then I will see what a 1G can do on 14psi.

If your talking about the diff conversion, so far about $200. That just covers the MX23 housing and open centre, RT141 brakes and axles and the Fairmont Watts link. Still need to get wheel bearings and an LSD sometime down the track. I think I might put the open centre back in for the time being.
The turbo's were a warranty claim.
