As a part of my due diligence process, I've been reading up on CG, RS-Tuning and RUFs respective 520hp kits. I've had numerous phonecalls and email exchanges with RUF (which seems like the best alternative by far when it comes to resale value) but they are just a) really tough to get a hold of and b) just a little bit over my budget. The latter wouldn't be a huge deal since it's really a proven package and clearly adds value to the car. I talked to various co-workers on the phone and it all just seems like a really big deal do get everything to work. So I looked at my other option which is CG/RS-Tuning. As far as I can understand, RS-Tuning develop the kits that CG sells. RS-Tuning are not local to me since they are in Germany but the main distributot in Sweden for CG is just around the corner, which is very conveniant.
Why stop at 520hp? Well, for a mostly street car (don't know for how long but I'm still in AWD mode) 520hp is more than enough to play around with. Secondly, it seems like a logical hp figure to stop at since anything above requires more or less a split-case operation and thus is not as cost effective. Anything about 520hp would mean replace con-rods, replace I/C, split-case operation etc. etc. sub 500hp would be even more cost effective (retaining the stock cams) but the 520hp is within my budget so I'll go with that.
Now to my questions: What is really the difference between the CGand RS-Tuning kits? They both have a 520hp kit but it is made up of different components (judging from their respective homepages):
CG:

RS-Tuning:
http://www.rs-tuning.de/tuning/993/993b4v3.htm
CG 520hp:
383KW/520PS / 5550 1/min
695Nm /4 560 1/min
RS-Tuning 520hp:
382 kW (520 PS) / 5800 1/min
710 Nm / 4100 1/min
So fairly similar while not 100% identical. I have the dyno sheet of the CG kit but not the RS-Tuning kit. I'm pretty sure more or less the same hardware is used. While the CG kit is purely a bolt-on kit, RS-Tuning are doing some "in-house" modifications to the car with their 520hp kit such as: 1. Modifying the headers and 2. modifying the gearbox and even 3. porting the cylinders. So while the output numbers are pretty much the same, the process is different. The RS-kit also implies that a live remap is done while the CG kit basically just replaces the DME unit.
I will most likely go with the CG kit, as that can be installed by my local dealer. Maybe even with a warranty. CG mentions nothing about porting the cylinders or modifying the headers. I assume those are all optional modifications, or modifications made to work with the RS-Tuning 520hp kit.
Here is what I am looking at:

What's a ballpark figure for the amount of working hours needed to replace the turbos and cams? I guess the turbos are fairly straight forward but just how big of an operation is replacing the cams, setting the new cam timing etc. etc.?
Engine out procedure? Any recommendations for "while you are in there" stuff? Replace motor mounts?
Neither CG nor RS-Tuning mentions anything about a replacement cluth or pressure plate. Is it fair to assume then that the stock 993TT clutch/PP can be used?
