Well how soon and how long will yo be outta the country?

JDM S14 has the big T28, he pulled a 12 with a blown seal on the turbo and a crack in the exhaust manifold, i'm sure he has a 12.1 in that car.

on a S13 you might make 11.99 or lower with those mods and a good 60' time.........

As far as the BigT28, thats what i plan to use on my roadrace/drift/autox S13 next summer.... Its a perfect turbine for your application, it spools fast and hard and maintains a pretty flat powerband.. lemmie find JDM S14's dyno and link it. its pretty sweet...
