Having a lift, air and many power tools, having taken my car very far apart and back together, etc....I could rush the job in 3-4 hours, or take my time in 5-6 hours max.
BUT, I highly recommend considering porting the manifold while at it or buy one, port it, do the install, port the old one to sell or as is.........

You will be making a great deal more heat with a bigger turbo, maybe less boost needed so less air temp wise but engine heat, much more.
I will post more pics soon but there is quite a bit you can do to open up air flow to the radiator and not to hard a job to add an oil cooler which I worked on today but decided to finish when I find the right wide and short in height oil cooler as I want to mount it low and ducted to not be in front of the radiator.
You can get more air to the radiator by just sanding off the back of the grill about 1.5" as it is filled in on the bottom half but some of that is not blocked by the bumper beam.
I will post some pics on swiss cheesing the radiator shroud, not much cheese left
The stock water to oil cooler will not help much when adding more power so I deleted it today, not sure how to remove it just yet but with a little tweaking mounted a Mocal oil cooler sandwich plate, tstat built in, had to run a heater hose 36" long to ensure the water is fed to or from the heater core under the dash, not sure the direction, does not matter as long as hooked up.
If you are building a car to put around it and get on it once in awhile, drag race, up to a point autocross, etc...then stock cooling might work but if you want to add some serious power and run on a road course or climb some great mountain roads, you will have to deal with cooling, just the way it is.
I am hoping to not have to swap the radiator, doing a lot of work to get all I can out of the stock systems except the oil cooler, I knew it had to be done right.
