I have a brand new quake se still in the box, PM if interested.
I would not suggest that motor. 7k is too high rpm and that motor will not have enough torque to push the tall gearing of the quake. Plus it has a 2mm shaft, to use the stock pinions you need a 2.3mm shaft.
This motor wil work great with your lipo and fit stock gears, motors mount and servo location:

I have had this motor in my quake and it works great. The 33 amp quark is also a good choice, much smoother than the mamba 25 and startup is better. Al knuckles are also a good idea, the plastic ones break and the graphite ones break if you look at them funny! Keep the diffs tight, they need to be checked. Front and rear bumpers take a beating, have spares on hand. Std steering servo is overkill, I use a 3303 futaba plastic gear and it is way too fast and has plenty of power. A 10 buck servo is all you need. I use the 10th scale wheel adapters, have used the mini t adapters but the tires look too small on the quake. The adapters are on ebay, can't seem to find them at the moment. Stock wheels and tires are fine, I just wanted to use foams on mine! I like my quake the best out of all the minis that i have owned, they are all sold now. I bought the new se listed above as a replacement for mine, but it does not appear to be wearing out, so i wil sell the new one! Let me know if you are interested.
