TUNING THE NISSAN RB25DET (R33)

Another great Nissan RB25DET R33 GTSt came in sporting a Holset HX35 turbo controlled by a Haltech E11 v2 ECU. And yes — it belongs to a female owner. Respect!

The combination of a Holset HX35 and Haltech E11 v2 is a serious setup on an R33. The HX35 is a large-frame truck-derived turbo that can support very high power levels when the engine is built for it.

We carried out a full custom tune to match the Haltech ECU to the car’s specification. The result was a strong, reliable power delivery with excellent boost control. Ladies — take note. Consider an R33 GTSt as your personal transport of choice. You will not be disappointed.
