If you're planning on going up to a bigger turbo the v2 or v3 may be a better option as it can give you the room to grow, at least to hybrid turbo levels. All should be sufficient for a stock turbo but the v1 is cheaper of you don't have plans to go beyond that I'm terms of turbo upgrades.
If you plan a big turbo in the future you'd probably want something beefier like the bravo alpha or DHM intercooler and crash bar(used as they're not in business anymore).
