okay, I'll have a go at this. I'm no turbo expert, but I am a jet engine expert and they aren't that different. on a jet engine, as with a turbo, there is a bearing called a thrust bearing. not only does it allow the shaft to rotate, but it puts a load on the shaft also. it keeps everything lined up properly. I also know that if a jet engine is mounted vertically, this bearing will wear out at an exponential rate because some of that load is "off" because of gravity. it won't make any difference in operation, but where it will hurt you is in shut down, or "spool down". the shaft will move down because of gravity and put wear on that bearing that will eventually cause it to fail. that's why when they use a turbine to power ships and trains, they are always mounted horizontally, not vertically. hope this helps you out somewhat.

i personally would just mound it left and right, i think the turbo will peform better and there will be less wear and tear on it due to its mounting. just my $0.02

PS. Custom jobs are cheaper and take longer but are soooo worth it, GOOD LUCK!!

Ok the thrust bearing write up is exactly what I needed to hear. Now I can show my dad why we cant put it straight up and down. I guess Im gong to start chopping up my kamikaze to fit as the turbo manifold, which is what I originally planned to do from the beginning. Thank for the help.
