This turbo story really takes time...
The housing above showed some significant signs of usage after cleaning...so after further considerations, I decided to buy a brand new one that one should be delivered within a week. Surprisingly it is still available.

I had less cracking on mine and it's been fine. But the new one is nice to work with. You are gonna make the cracks. lol.

Did you get the .48 or .63 version?

Well, I want to limit a chance that some small piece of the housing gets loose and possibly damages the turbine wheel. In other words, to do it and forget it.
Based on the remarks from JohnV and as I want quicker spool rather than higher top end power, I went with the .48 cosworth.

I'm sure you'll be happy with it. That's a good size as Volvo used it on the T3 equipped 740s. Just not such a large outlet on their version.
