ID this GT25xx housing

Here's a housing I took off of a cheap beat up GT2560.

It has a "tongue" for divorcing the wastegate gases. Perfect for my custom tongueless divorced pipe downpipe. I've never seen one with a tongue before. How common is this? The turbo it came on had the fundky bolt-on (i.e. not hose end) attachments for the compressor inlet and outlet...

off a Skyline GTR, the one with the ceramic turbine... IIRC.

Hurm... then it should be a t3 housing? I have a rb20det in the garage.. shame I'm too lazy to unbolt the turbo and check that

Hmm, the turbine wheel appears to be ceramic all right. Does this have any advantage over a regular GT2560?

Yah... it has a tendency to explode at ~14psi give or take....

Kindof like built-in overboost protection

What power level is that? Shaft RPM is more a function of power than boost...

I'm just going off the ~ death zone on the car the turbo came off of. The ceramic turbine blades had a short life starting at about the 14psi area.

Actual power level... unsure. I wouldn't push it. I have one on the 240 project of mine, I have a replacement turbo already... I don't trust the ceramic.
