The stages

Stage 1

adds service, intake clean and tune

from $2,570.00parts, tune and servicing, everything in Stage 1

Service, clean and tune. We service the engine properly, chemically clean the intake and EGR, then tune it to the engine as it actually is on the day: fuel and timing, set on our own dyno.

The work in the price

  • Custom Dyno Tune, Stage 1 and 2$1,250.00
  • 4WD Minor Service$660.00
  • Intake and EGR chemical clean, single manifold$660.00

Stage 2 Power

would add intercooler and intake

No intercooler, intake or transmission cooler is listed in this stage for the 1HZ, so there is no Stage 2 Towing either. Ask us. There may be another way to get there.

Stage 3

adds a turbo conversion

The point where the hardware sets the ceiling instead of the tune. A turbo conversion puts in more air, and the tune adds the fuel to burn it cleanly.

This is a fitting job with a tune around it, not a bolt-on. It wants supporting work (cooling, clutch or converter, sometimes the fuel pump) and we will say so before anything comes apart.

A build, not a package. A larger turbo again, which is where the standard bottom end, the driveline and the cooling all start needing to be part of the conversation.

Before you choose a stage

We will tell you what your build needs to stay road legal before any work starts.

GTurbo offer G200, G333, G380 for this engine. A bigger step than the stages above is a conversation, not a checkout.
