Any laggy turbo will make big numbers, a T28 would make the same power.
It was overpriced, has a no-better-then-stock elbow, and a 5000rpm+ boost threshold. GT25 blows it out the water these days.
Because Deans made 221 or whatever doesnt mean this will make even the same, nevermind another 20 imaginary HP just because hes spent abit more money on a few more parts.
