New turbo with divided housing, you know me I like big turbines. No back pressure in the exhaust manifold. Spools great.
No trouble with mains or caps just stock, after all with seven mains and only turning 6000 RPM works good.
The block just flexed and broke the outside of the casting.
Working on some ideas to fix the next weakest link.

Small turbines are for engines with poor flowing heads..
Nice work! Which turbo are you using?
Time for a mid engine mount plate ... sounds like you pulled the block apart at/near the engine mounts..
With the correct design you should be able to have the mid engine plate float between 2 fingers coming off of the frame = when its time to turn the wick up - put a hardened 1/2" pin in to lock the plate to the frame mounts.
This will move the torque transfer point to the bell housing flange - a lot more metal there than the side of the block..
