I have the socket. Got it for free a few years back. It's not really worth buying if you're only going to use it once or twice... Find somewhere to rent or borrow it.

And for the record, flywheel removal is covered in the FAQ.
More to the point is what kind of torque you need to put on the socket. You'll need either a good 3 - 6 foot breaker bar, or a good 500 Ft-LBs or greater impact gun. Heat the nut to remove any loctite. Nice thing about the impact gun is you don't have to figure out how to hold the engine as you put > 1000 FT-LBs of torque onto the nut with a massive breaker bar.

depends on the impact also i suppose. mine is a 400ft/lbs rated rebadged Mac tools from IR. it does the rated amount, being in the auto industry i have seen many not come anywhere near their claimed output levels. it's a similar science to dynomometers, some are more accurate than others. but this sucker is also as heavy as it looks, don't drop it on your foot... some of the front hub bolts i had to heat so extremely that i thought the oil in the pan was going to ignite or the head of the bolt snap off(oxy acetylene glowing cherry then hit up right away with 300+ ft/lbs).
since those experiences i put the flywheel nut on as tight as i can get it with the impact, with the front bolt i cinch it down with a ratchet and then a single tap on the impact to get it in the 90ft/lb ball park. i believe most shops just zap it on as tight as their gun will go and it only gets tighter with age.
i do that because i have seen a flywheel key sheared almost in half when one engine locked up at redline, that is how flywheels explode.

Back on is easy.
Follow the FSM instructions and torque for the front hub.
The flywheel, put some sealant on the back side of the bolt and a bit of red Loctite on the threads. Tighten the nut down by hand, then turn it the distance of 60 degrees with the impact. 60 degrees is the distance between each point on the nut, so just make some marks on the flywheel and nut for reference.
