I think the subframe needs removed on these,if you have access to a ramp/air tools then I am guessing 4-5 hrs if you don't encounter any problems, ie seized front susp.bolts etc,if you are doing it in your driveway then add a bit more to that time,it is not a job I would want to take on without a ramp and proper tools,also it is false economy not to replace the three parts of the clutch when the g/box is out,if it has a dual mass flywheel then you may want to fit a solid flywheel kit,motor factors usually do these now,good luck.
