Granite Brushless Granite Mega Rebuild | Which motor should I use?

[suchtragedy]

So I picked up a used Granite Mega 4x4 brushed for 100 bucks and I am throwing spare parts in it to make it kinda close performance wise to my Granite BLX. I have put in the BLX diffs, arrma 15kg servo, and BLX outdrive shafts and I have the BLX stock aluminum motor mount with BLX slipper and stock spur and I got lots of 32p pinions I can try out.

So as far as motors/esc I have a few 3650s laying around and a 60a brushless hobbywing esc try with it, but can go with my 3s BLX esc if it won't cut it when I upgrade my BLX to 180a and 4s capability. I am hoping to get close to the same performance or at least 75% of the performance my BLX has on 2s. I have a 3100kv, 3900kv, and 4300kv motors in 3650 size to try. So which motor/pinion combo you think would be my best chance for success? And do note I don't want to have it be faster than my stock BLX, I am treating this as my spare/loaner for when I go bashing with friends and get them hooked on the hobby if they aren't into it yet so I still want it to be fairly tame but not slow.

I worry the esc and 3650 motors are going to be too small to push this truck reliably but it's all I got motor wise to work with for now.

60amp I don’t think will work. Need at least 100. Get 120 n run that 3900

^ he’s right but I suspect that’s one of those Chinese 60 amp escs. If that’s the case it’ll take a 3650 just fine. I’d use the 3100kv. Slower than your granite and less stress on the esc.

WELL I'M A SUPER DUPER RC GUY WIOTHJ ALL THE KNOWLEDGE MY DUDE! YOU NEED 2400KV MAN THAT'S ALL WRONG. CALL ME WHEN IT CRASHES SO I CAN SAY HAHAHA!

Oh sorry. That's how I was treated when I proposed taking my already broken Granite and throwing 4s in it just to see how fast I could get it going and I got poop all over for it. Enjoy your stay here with the rocket scientists. But seriously; Good luck man. I hope you have fun and a much much better experience than I did.
Chiiiiineeeese Amps!!!

You're really going for it! ? I applaud the effort ?

The hobbywing 60a and the 3100kv 3650 motor made out of spaceage chinesium alloy seem to be working fine and power seems to be right where I was hoping to get. Ran two packs so far so good, we'll see how long it lasts.?

Chinese 60a 3650 3100kv chinesium alloy power!!!

3650 motor 3900 kv with 10T pinion on 32p.

I realize this is over a year old but in a similar scenario. I have a cheap chinese 45amp esc and a 3650 3300KV motor from a ZD racing truck that I cannot find parts for and is broken as well as a 540 sized 4300KV GoolRC motor. I want to get my second Mega 4x4 back up. I only plan running 2s and really only upgraded to the HD inputs. I'm thinking the only real option would be the 3300KV. But would I want to change stock pinion? Really don't want to spend much if anything. This was originally a parts truck but I never really broke anything on the main truck. Want to get it going for my son.
