Has any body done this and will i have to use the gq gearbox and diffs or will the mq 5 speed bolt up to the 4.2 turbo motor, my mq ute is a little underpowered as i tow a big trailer and was thinking about keeping the ute its in really good condition or should i just buy a gq ute thanks for your help

I am pretty sure you'll need a gearbox that comes with the TD42.

But.. are you sure you can't squeeze a bit more out of the SD33T? They are a very respected motor.

Nothing is the same, its all completely different.

Also the transmission tunnel in the GQ is a different shape to the MK so you might have issues fitting the later trans in there. The MK is flat & wide while the GQ is a lot thinner but much taller.
