Anyone Replace Turbocharger assembly based on a new Garrett core
On the Golf R? What about the hp reache after replacing?
Any other recommendations to get 400-410hp. Without replacing the turbo K04
Lots of people using the Garrett GT28 and GT30 series turbos on Golf R's now.
You are quoting 400-410hp - no doubt you mean at the engine, rather than measured at the wheels?
-K04 hybrid turbos are getting around 230-235kw/310hp at all four wheels.
- With GT28's they are getting a safe 250kw/335hp at all four wheels. This is on a stock engine and stock injectors.
-With GT30's they are around 300kw/400hp+ at all four wheels, but this power level required new rods and injectors at a minimum. You can push harder if you want, but then you start breaking things and it gets very expensive.
Note that the power figures i have quoted are on Australian dyno's, which tend to read quite a bit lower (more realistic) than American dyno's.
