A HUGE amount.
Couldn't sleep one night and got bored,so I grabbed the JRX swag bag of parts and an SE chassis,by 5:00am,I had this!

It's a blast to drive,especially without a slipper clutch,as the state of the rear tires show.

Used XX front hubs and rims,a vintage Novak 6-10HRV ESC,a Trinity 17 turn motor and servo taped in (hey,why not keep it OG?!) a Futaba S145 servo.
My 5500 LI-PO *just* snaps in the battery compartment! HA HA HA! 25 minute run times,anyone?!

The body came with an SE that I bought for parts,all the black was flaking off,so I just repainted that part.
