Wicked build mate! **** that thing is gonna haul. Watch that torsen diff though. They can be kinda unpredictable (esp if they're tightened up). They definitely dont behave like a clutch type LSD.
The 1mz coil-on-plug setup is definitely much tidier than LS1 coils would've been. You could've possibly used vvti 1uz or 3uz coils too? not sure if the would've fitted as well or not?
Keep the updates coming, cant wait to see the final result
