HKS2535 vs TD06-20G

Tossing between this 2, the dilema is that HKS is brand new with a .64 exhaust cover, and the TD06 comes with manifold and wastegate to suit RB20, but theres a $1000 difference, obviously the TD06 being more expensive... Power wise im sure the TD06 will make more power but im also sure that i'll need to upgrade the fuel system and maybe the exhaust modified at the turbo. The car has a S-AFC, an ITC (ignition timing coverter) boost controller, pod filter, GTR front mount i/c and a 3" exhaust...
Just unsure if the difference in power is worth the $1000 difference and the upgrades that it might tug along ? ant suggestions ???????

Normally when you get a turbo that can put out more power, you have to build it for that power. Meaning, port and polish heads, bigger cams, even more fuel, even bigger injerctors, etc. Its a lot more money, than just the turbo cost, to get the full potential of the upgrade.
