B23E non-EGR + turbo help

I have a 1979 volvo 245, there’s been lots done to it. It’s got a b23E non egr motor from a Canada car put in, and has a 13c turbocharger. I imported it this way.
Long story short it was a very profound shop for nearing 3ish years and $10,000 and it came out with a blown turbo and steering rack, weird combo.
Now this $18000 lawn ornament needs to get fixed either the budget allots it or not, this things gotta move.
The turbo isn’t AWFUL, still hits boost just fine. I haven’t wrenched on this car myself much at all. I have shop notes I can add if necessary. Pardon any ignorance this is my first turbo car with problems. But my suspicion is lead by perfectly fine compression, great hvac, now, it was setup just awful, notes explain where things were and how things were.) And at idle there will be white smoke from exhaust (if idling for about 30sec or more) the turbo hot end leaks at the top of the pipe towards the hood, where it meets the downpipe, leaks at flange from the top. I am straight piped into a muffler right before tailpipe. I’ve been told the weird backpressure may be what’s making it leak at the top of the pipe and not so much the bottom, but it tends to smoke and puff up from there.
So, I have a Td04-19THF from speeding parts from a separate engine build I’ve been playing with for some time. But I’ve been told 941 ecu/ezk combo with that turbo set from speeding parts is too high for the b23E and will cause predetonation issues, and chips for the 941 ecu to allow more boost are advancing the times for a normal compression b230ft and not a b23E+t
Basically, I’m willing to throw away the 10k worth of work and standalone the rig, but for now Id like to enjoy what it is. and just get the pig to stop smoking at idle and rest my mind with a stock 13c replacement. I’m having very hard troubles sourcing a solid turbo (it has older eBay replacement turbo) but the ones I see look like cheaper chinese parts like what I’ve got but for nearly $1000,
Can someone help me source a new stock replacement? Trying to keep boost under 8lbs for sake of my valves and predetonation prevention lol
