Way trooper shows new face (8)

I believe the answer is:

stranger

I'm a little stuck... Click here to teach me more about this clue!

'new face' is the definition.
(a new face is a stranger)

'way trooper' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'trooper' becomes 'ranger' (I can't explain this - if you can you should give a lot more credence to this answer).
'st'+'ranger'='STRANGER'

'shows' is the link.

Can you help me to learn more?

(Other definitions for stranger that I've seen before include "Odder, more peculiar" , "Alien, foreigner" , "More odd or unknown" , "More odd or wierd" , "Non-acquaintance" .)

I've seen this clue in The Sun.
