Thought I would throw up an update..
Sump back
motor complete
Ended up going with an ROSS balancer...
.84 T04z on a 6 boost manifold & turbo smart pro-gate
Motor is in the car & fitted, just waiting on the new injectors (old one's had variances when tested) to arrive, fuel set-up, dump and cooler piping to be done before she gets run in.
Roughly 2 weeks before she's on the road again.
