I'd go MMM and 1518 on 5 or 6s lipo, or just 1515 on 4 or 5s.
Rx8 and one of the lower kv truggie motors on 5 or 6s lipo would also work great.
For a slightly cheaper option the XeRun 150amp esc and one of the lower kv hobbywing XL sized motors.

All three options should work perfectly well, all have their obvious pros and cons ( sensored vs sensorless, cheaper vs more expensive, customer support levels etc etc ).
