This may sound like a very stupid question but Iam wondering if any performance shops do this sort of mods. There are some vehicles like the Hyundai accent which can have the existing GSR 4x4 turbo engine and driveline popped straight into the existing shell. Is there any way that this can be done with say the cavilier 4x4 drivetrain into the astra? Has anyone ever heard of anything like this??
