Problems fitting K27 turbo

I posted this on Rennlist, but I would be curious whether any of the people who go to this board would have something to say:

I have finally got my 3.0 fully assembled, and I'm ready to put it in the car this weekend. Sort of.

The engine is stock, except '86 exhaust, Euro muffler, SC cams and the K27. I am writing this long post because I did not find the K27 to be a simple bolt on, and I am surprised that no one else seems to have mentioned it. I initially had trouble with the exhaust collector pipe(several posts here a couple of months back until I realized what the problem was), but that turned out to be a bent pipe that I purchased used. An undamaged pipe was located and installed, but the turbo bracket didn't line up. I cut and rewelded the turbo bracket, so the turbo was correctly supported on the exhaust flange and at the rear console. That took care of the hot side.

But the cold side inlet doesn't line up (the short hoses on the multiply bent pipe compensate to some degree, however, I feel that the offset at the turbo inlet will be a problem for air flow) and I had to relocate the holes in the rear shelf to get a neat fit on the cold side outlet.

None of this seems surprising, because the K27 is clearly wider than the LDZ it's replacing (unfortunately, I don't have my LDZ to place alongside my K27 for comparison, because this all started when UPS lost it), however, I'm surprised that there are no comments on any of the internet boards about the details needed to fit the K27. Do others shorten the steel pipe where it mates up against the cold side inlet? Is there some other trick? I can see that the very small distance between the engine mount bracket in the car and the cold side inlet pipe will be even smaller, when I finally install the engine.

Can anyone chime in with their own experience, please?
