It's likely to cause you more hassle than it's worth - many other good options out there if you pick the right turbo.
This is coming from the bloke who melted the vanes inside a turbo due to not really understanding what was going on - yet still recommends them... They're awesome - nothing will quite produce the same response when set up well, but get it wrong and it spells disaster for the turbo and engine usually. People assume they're as easy to get working as a wastegater - WRONG - I guarantee you'll spend the first 3000 miles screwing round with the turbo, trying to make it work right, wondering why when the boost goes up, the car performs like a sack of shit, barely moves and smokes like a twat and the exhaust manifold is doing a great impression of the surface of the sun - yet the boost gauge is reading 25psi - trying to make the actuator sit properly so it moves enough blah-de-blah... If you've got the patience - awesome, go for it, but if you just want a car to drive and aren't interested in doing a bit of your own development, don't bother.

This included the engine being removed 3 times as I wasn't happy. Though I've done over 3k miles now fairly happily. Just got to watch the EMP
