Have Trail Finder 2 Mojave Midnight Edition. Stock motor and stock electronics. Would like to keep running NiHMs batteries. Is there any brushed motor that would give me a bit more speed than the stock one??

If you've got the stock 45T motor, you could try swapping that out for a Holmes Hobbies Crawlmaster Sport 540 13T - I've done that with a number of builds over the years and it offers a significant amount more rpm, plus is nice and smooth - all for around $15.

You could and/or also try a slightly larger pinion gear on the motor - stock they are 14T, perhaps go up to 17T for example?

I'd also seriously consider swapping to LiPo batteries - just a 2S [shorty] is more than enough, although you'll probably want a compatible ESC (as I'm not sure the stock RC4WD is Lipo compatible?)* - if you go that route the Hobbywing 1080 is an excellent unit - very quiet and programmable with the included controller, for around $40-45.

*edit. seems their Outcry III ESC does have a Lipo cut-off as standard, so you could stick with the stock ESC for the time being too.

Hope that helps!

Where'd I put that 2mm driver?
I believe the Outcry III is a rebranded Hobbywing 1060. Going to a lower turn count motor or a bigger pinion would increase wheel speed, but I'll put out another recommendation for swapping over to LiPo if you can. Even just a 2S LiPo would give you more wheelspeed, and a 3S would probably be more than you're wanting. Both would give you the added benefit of likely longer run times as well.

Thanks! The stock ESC is compatible with LiPos. But Im running a full interior and for what Ive seen with LiPo batteries they seem kind of bulky and will not fit with the interior in place. Right?

Will keep the LiPos in mind. Is the charging more complicates or troublesome with LiPos? I have a good charger with LiPo balance capability but have never used that function.

the only complication is the fire risk, which although quite low is still there. Just a fire proof charging bag or box will prevent that.
