ultimately the decision is obviously yours man, u need to ask yourself what you want out of your car!! do u want to be thrown back in the seat or do you wnat to be able to flick threw the gears quickly? Each of the turbos has its pros and cons as im sure others will agree.
Everybody seems to talk about h.p (what we love to call the wank factor) Ok h.p is obviously important for bragging rights, but what about how much torque the car puts out?? thats what throws you back in the seat and holds you there, ask yourself what you will use the car for and do your research into what turbo is going to provide you with the needs to achieve your goals, remember hp isnt everything!!
