Turbocharger differences, TD04-12t, 14t and 19t

Evening Chaps

Whilst I'm in the habit of throwing money at the car, I figured that after 116000 miles a new turbo cant go amiss, can it

So will all of these physically fit, looks like my car has the 12t as standard, and it starts running out of puff at about 5900 RPM, limiter is set at 7000 rpm so a fair bit of the rev range left to go.

Currently running a BSR stage 3 tune now, with associated hardware, I've heard the 2.0T doesn't appreciate a load of boost at low RPMs and can bend rods, but I'm not going to be running any more boost through it, just maintaining it through a higher rev range, and looking at the compression ratio and specs, I should gain high up but not lose out that much low down.

Anyone know if they all have the same fitment intake and exhaust side? Just bolt on, bolt off? Thinking will buy new studs, gaskets and turbo oil pipes, new banjos and o rings at the same time.

Any help appreciated

iirc the only thing that changes is the compressor side, gets bigger as you go up, but the real power limiter is the turbine side, what power level are you at with the map?

Should be around 260Hp/270 ft lb with the map and the hardware changes to inlet and exhaust so far.

Not expecting great gains but would just like it to hold the power higher up the rev ranger for overtaking etcs.

Sounds good, have not long picked up an 05 2.0t and looking to remap soon, if want to start going more nice to know can get 250ish without major internal work
