Will f18 diesel gearbox fit vectra sri petrol?

The F18 diesel gearbox is not compatible with the Vectra SRI petrol engine. The F18 diesel gearbox is designed to be used with engines that produce higher torque than petrol engines. The Vectra SRI petrol engine produces lower torque than diesel engines, so the F18 diesel gearbox would not be able to handle the power output of the petrol engine. Additionally, the F18 diesel gearbox has different gear ratios than the petrol gearbox, so it would not be able to provide the correct gear ratios for the petrol engine.
