Having this week hit 130k miles my K04 finally seems to have cracked and subsequently failing under maximum boost. On my quest to 300bhp it reporting around 250bhp on the dyno, some 18bhp less than 6 months ago with bucket loads more mods mounted.
As a result, I'm considering either a straight replacement or a turbo dynamics stage 1 hybrid.
I must say that I still am not convinced about the aftermarket manifolds and might retain the oem and limit bhp/torque to suit and retain performance/ reliability as opposed to chasing figures.
The stage 1 turbo dynamics is attractive as it features an uprated 360 degree thrust kit amongst other bits and I imagine would beat suit my purposes.
Does anyone have experience of this and can offer opinion?
I understand that westy went for new K04 and is boasted huge torque. Be interesting to hear others views.
