i have read that the td06 is meant for much more power than i want - 400+ and that it will be quite laggy? ive been told that the stock internals of the wrx engines and gearboxes are ok up to 350 bhp but when you start heading over that is drastically reduces lifespan and increases potential for failures

sorry to jump onto a post but its kinda relevant. I have a 2.5 WRX hawkeye - i have done so much reading about turbos im getting a little confused and they seem to be impossible to find!! So far i have equeal headers,full decat exhaust and front mount intercooler. Im looking to end around 350 bhp and from what i have read i think all i need is a turbo upgrade and maybe upgraded injectors. question is ... is the vf48 the best turbo for my goal and where can i get one?
