    Default T3/T4 turbos

    Sorry to keep going on about turbos...

    I've decided on a T3/T4, so what spec is best for the Q4?

    I've currently got stainless manifold, C&B medium street inlet cam and a Squadra chip (will be remapping one day!).

    I was thinking the 60 trim but that seems to be for about 450bhp which is way more than I need....so 50?

    Then, which compressor and turbine sizes would suit 300bhp target?

    Read a lot about ball bearing turbos being much more responsive and faster spooling, but it there THAT much difference compared with a journal turbo, to warrant the ?300 increase!?
