I'd probably say at bare minimum get the rcmax diff housings and keeping the stock tires together will be another issue

I'm running the foamless tires so hopefully that won't be an issue
Can't say I know what your talking about. Are those the rcmax ones? And I don't own a rcmax engine but from what I've seen and can see happening id suggest aluminum housings as the torque of that 50 is gunna side load those pinion bearings
2.0 diff/housing and drives will be destroyed 
Run it as is and upgrade whatever gets battered from the increase in power... or you can drop another $1k+ on drivetrain bits but that won’t guarantee no problems

What's different from them and the 1.0? Thought we pretty much agreed a 50cc was about the limit a stock ish drive train would handle with out tons of upgrades.2.0 diff/housing and drives will be destroyed

@John Parks knows
No wasn't saying 1.0 are better
the op has got a 2.0 and was just saying they will be destroyed

Well I know they physically fit. I have a 2.0 rear housing in my 1.0. Actually didn't see any differences.
They are both the same part

Hmm, I'm still Like 80% sure 50cc was the limit. May be John will give bit of input.
50 wont “destroy” a 5t drivetrain but even using a 34 reed the pins and cups get hammered to the point that I used to replace them at least once a year. Accelerate that as you go higher in cc
Don't rekon it will be a total fail
but can't see a stock setup lasting long

No it wont but it will be wear issues not really total sudden failureDon't rekon it will be a total fail

I say leave it and let's see what happens...for research purposes
We should all go and set up some bleachers...I would love to see this in person
