Will a VT Commodore V6 3.8-litre engine fit into a 2004 WK Statesman V6 3.8?
Answered by CarsGuide
4 Oct 2022Both those models of Holden used the same engine; the L36 (Holden's internal code) Ecotec V6. As such, you should be able to fit the engine from the VT Commodore into the Statesman with very few other changes. The biggest hurdle will be if the Commodore donor car was a manual-transmission vehicle, as the ECU may be different to the Statesman's unit to allow for control of the electronic transmission. The best bet is to retain the Statesman's wiring and computer and change over only the engine hardware from the Commodore.
The other (minor) catch is that the VT's version of the V6 was tuned for 147kW, while the later version of the same engine in the Statesman was good for 152kW. There was a small torque difference, too (304Nm plays 305Nm). So you'll be trading off a small amount of performance but, realistically, not enough to notice.
