Ok now I think we are getting somewhere. Ok so I'll put out my ideas here and let’s see if we can narrow down what we should swap in instead.

Bottom End:
From what I understand with even inadequate oiling on some engines do to failures we have yet to see a thrown rod due to suspected failure of crank/rods/wrist pin. If this is the case maybe a piston swap max and rods if necessary to do that until I pop something. This is the expensive way to test power levels of components but I don't see the point of upgrading something until we find it's weak point. Dry sump oil system with reservoir and large cooler.

Top End:
Valve job, port matching,

Charge Air:
custom intake with secondary injectors and vband flanges. Full core FMIC with secondary air/water cooler. BOV's and e-boost 2 from turbo smart or equivalents.

Turbos:
Sequential turbo setup. Running a stock/RB size turbo for low rpm and Large turbo for high rpm. Use a cutout valve to isolate large turbo and help spooling time and lag.

Engine Management/Monitoring:
Possibly run stock ecu with flash and piggyback if I can find some way of integration with whatever I use for secondary fueling and wideband monitoring. Otherwise standalone. Currently rigging up a prototype system to run monitoring in car. If I can then merge this with a secondary system for egt/wideband.
