MBX7R Nitro owner. New to electrics, however. I race at a medium-sized indoor track with high traction. Looking at the following ESC/motor combo. Will the 2000kV motor be suitable?

It should be more than enough. Probably need to turn down power level at ESC and Radio.

I run 4s/1900kv on large outdoor track with no problem.

How would it compare to the 2200kV?

I currently have the Tenshock X802 v2 (2100kv) from my previous buggy, and still need to buy an esc for the mugen. I've been set on getting the Xerun 150a, but have been reading that the Xerun SCT-PRO would also be an option. Any advice on which one I should use for the mugen?

I use a tekin 2050kv in mine with a 13t pinion on a similar track as you and it works great. I only adjusted the current limiter in the esc down to 50.

150a vs SCT PRO. Had them both running 1900kv.

150a is big and quite a bit heavier. Barely fit in my x6. Ran great. No complains. If you ever plan on running more than 4S, you're set.

SCT PRO is smaller, lighter, fits better, and has plenty of power. I like it better for the size and weight reasons.

Good to know, thanks. I just checked my x802 v2 has a max amps of 130a. Does that mean a 120a esc won't be able to handle it?

Do you think the 44T spur with the 14T pinion is a good starting point with a 1900KV motor? What batteries is everyone running? I bought a couple of the SMC 4S 60C 6500MAH packs. Is that a good choice? I thought about buying a one of the SMC 4S 70C 4600MAH packs to play with.

Just got all of the pieces so I am going to start putting it together.

Thanks for any advice.

Also interested in battery choice. I just ordered the ProTek 4S 100C 6700mAh. But confused as to which charge cable goes with it.

Sct pro will handle it no problem. The mamba max pro handles ebuggy fine and it's rated at something below 100 amps.

2200kv = way more than needed. I run a 1700kv on 4s. More power than any nitro, maybe a couple mph slower on top if you're running on a really big track.

Sounds like guys are running really big batteries (6500mah+). If you're doing 20+ minute runs then that's fine but if you're going 10 minute mains, think about running smaller packs. I make 15 minute mains on my setup with 4500mah packs, which are several ounces lighter.
