As said before, I moved the turbine 2 inches forward trying to reduce tail weight....also cut about same length of the bypass mouth.
By doing all that and with the addition of the tail cone, I was short by 3 inches with the tail pipe.
My supporting friend Tam made me an tailpipe extension

As a consequence of moving the turbine so far front....I had to made a small mods to the turbine bracket in order to archive the more displacement possible....not big deal...but forgot to picture it [&o]

Anyway, this is also the reason for making my turbine base mount removable, due I was not able to insert the tanks...

The exact lenght cutted out of the bypass was 1.5", and to be able to insert or dismount the turbine w/o having to remove the bypass/tailpipe, you'll have to make a notch at the front lip of the hatch OR instead of 1.5" just cut 1" .
