Depends what power, if you're chasing 300rwhp the Turbo pump works great, there's a lot of peeps in the states using Supra pumps and it's a bolt in item (for SW20 Turbo anyway), and that's for even higher HP love.
I suggest you use the said pumps for easy bolt-on-ness.
No "stance", no "hellaflush", none of that bullshit. Nothing but no grip on full boost.
