If your 1j is ****ed, it'd be cheapest to go ge 2j bottom end so you can basically reuse your entire existing setup with only modifying oil feed for the turbo and possibly intercooler stuff due to added deck height.
Vvti is awesome, but mostly in stock form or for cars that see mostly street/daily duty. If your goal is wide open throttle peak power, you're basically wastin your time and money going vvti. Partial throttle is where vvti shines, and under 4k tpm at that. Vvti cars (both ge and gte) are only faster at partial throttle from down low, punching it on the freeway at 3500rpm plus the differences are pretty much negligible.
