The factory 01 car has come up against several GTRs at the track over the years. At Autobahn, it was about 20 seconds a lap faster on the long course, IIRC. At Summit, we saw one or two running about 10 or so seconds slower than us on a track with about a 76 second lap time for the 01. So, based on the experience with the 01 car, the GTR really isn't close at all.
Either the GTR has an inflated reputation for speed, or most people don't know just how fast the SLC really is.
20 seconds faster,, that is quick, but is it a fair comparison? There are too many variables to really generalize that it's that much faster. The 01 car is a full up race car, with lots of down force, and sticky racing slicks. What did the GTR have? Was it essentially a street car doing a track day, or was it a race prepped car with full roll cage, racing tires, ect? Was this an actual race, or just on a track day? Just going from street tires to slicks could account for 5-10 seconds. Also, isn't the 01 driven by a professional race car driver. What kind of driver was in the GTR? If it was a track day, it's a good possibility it was just some guy that wanted to get his foot on the peddle with his car, and like a lot of guys that take their daily out for a track day, they are certainly not going to push every second.
There is a youtube somewhere of a Ron Simons taking an Ultima GTR 720, I believe around the ring (This was an actual test driver, the show/clip also starred Sabine Schmitz), I would think that these cars are very comparable in terms of performance to the SLC, there was light traffic, and he was still only able to get about 7:28 (IIRC) which is still blazingly fast, and yes the car was on street tires. So when the Nissan GTR Nismo does a 7:08, that says a lot for what technology can do.

Trust me, I want the SLC to be the fastest thing around. Why, because I am in the middle of building one. I don't want to be envious of the guys that test drive exotic top end supercars, because I'll have one with the same capability in my garage.
Good for you - GTR is an amazing car. I'll admit I second guess my decision every time I see a C7 Vette on the road.
I did too at first, esp the first time I saw the C7 (definitely the wow factor), and looked at how much you get for about the same price as a budget conscious SLC (I'm looking at being just a tad over $60k), and thought instead of still building it (about 3 months into it), I could be driving, comes with a warranty, and makes for a nice daily driver (esp if you want to use a factory type steering wheel making ingress and egress a little tricky.)
However, there are a few things that take me back to why I went this route.
1) It's always been a dream to build a car -ever since I was about 10
2) The car really sticks out, if you want a conversation piece, you got one. Right now as just a rolling chassis, I towed the car on a trailor to the workshop, and you would not believe how many times the car was photographed. And that was a roller without even the body prepped (no holes cut out for anything). As for the C7, it looks great, but I see at least 3 to 4 of them a day, which does make it less special. Because we have to be honest about this one, one of the reasons we drive a car like this isn't just because it is fast and handles great. If handling and speed were the only factors, you could take a Miata, swap in a V8 (it's been done multiple times), throw in some suspension mods, and you would have one killer track car for a whole heck of a lot less, but it should would not have the "WOW" factor the SLC has.
3) The car is incredibly light. Even if you put all the bells and whistles into it,, it's still going to come out about 600lbs or more lighter than the Vette. I've always wanted something that will scare the heck out of me and would continuously test my ability to push the car to it's limits. I think the SLC qualifies.
