new project in mind, help with motor choice

Hello, long time that i've not come here on the forum!
I've try the nitro truck since last winter, but now i want to coming back with brushless.
I've bought an Ofna DM-one 1/7 on-road car and i want to convert it into brushless.
For the controller, i'lll go with the MMM V3, but realy don't know wich moto take.
I want to run it on 5s lipo, and kept the 2 speed assembly.

The bad thing is i've sold all my charger and lipo pack, so i've to buy new stuff$$$$$$$$$$$$$$$$$$$$
The charger while be the same that i had last year, an hyperion 0610i, and probably go with TP pack.

So please, i,am waiting for your help.

Thank you!

David
