TUNING THE TOYOTA 3S-GTE (GT4)

This nice Toyota Celica GT4 came in for some treatment. It featured a hybrid turbo setup on the Toyota 3S-GTE engine and needed custom ECU mapping to match.

The Toyota Celica GT4 is a classic four-wheel-drive turbocharged performance car. The 3S-GTE engine is well known for its strong power delivery and excellent response to tuning. With a hybrid turbo fitted, the potential is even greater.

We carried out a full custom ECU tune on the dyno to suit the hybrid turbo specification. Boost, fuelling, and ignition timing were all optimised for the new hardware. The result was a significant power increase with smooth, linear delivery throughout the rev range.

The GT4 left in great shape, with more power, better response, and a reliable setup built to last. A great result on a classic Japanese performance platform.
