930 Turbo to Intercooler Hose Question

Would appreciate knowledge/help on the following.

A 3.3 930 with a k27-7200 and original intercooler - the position of the turbo to the pipe that goes to the intercooler is off (due to the larger turbo) - does anyone out there make/sell a good quality silicone hose that will compensate for that difference (a short semi S hose will do) - a regular straight hose kinks it and does not sit correct.

Thanks in advance.

Better to fix the position than go to effort to work around it. If the turbo is not in the correct spot nothing will fit correctly; the air intake, exhaust flange, muffler, or intercooler.
The K27 hot housing is 10mm more thick than that of a 3LDZ. To compensate the bracket that holds the turbo to the engine must be modified by either slotting the existing holes and slide it over or cut and re-weld the bracket.

Best fix is ditch all the pathetic annoying o-rings.

Then cut the bottom inch off the obsolete cast aluminum charge pipe so the 0-ring crap is gone and the bottom of the charge pipe is the same outside diameter as the small exit pipe on the top of the K27 turbo compressor cover and buy a piece of multiply reinforced silicone hose and a couple hose clamps to connect the bottom of the newly modified charge pipe to the K27.

You'll have to enlarge the hole in the engine sheet metal where the top of the K27 turbo compressor cover exit pipe goes through because it will be offset compared to the previous 3ldz exit pipe.
A die grinder and carbide bur will do that nicely.
If no die grinder and air compressor to run it is around then a high speed 1/4" electric drill with a carbide bur will do it. Slower but it'll get the job done.

I welded this ring with laser welding on it. at the k 27 you have to cut the neck 15mm. then you can use the oem pipe to intercooler
