perrin shows 7163 is better than 6758 in both low and top.

Here is a long NASIOC thread with quite a few results and lots of EFR info if you want to wade through the many pages of it.

I'm not sure what was up with the Perrin results but real-world the 7163 isn't going to spool faster than the 6758, especially if you are using the .64A/R housing on the 6758 which is what I would definitely use on this car. The 6258 really has more than enough power in it to get people in trouble and will spool super fast.
