Yes you can fit your cielo A/T with a TC.
It's beneficial only if you like revving your car close to the red line, as TCs are know to work effectively at higher rpms.
Domnic once told me that a 2 stage TC will make a bigger difference. While the first and smaller TC kicks in at low rpms (as it doesn't require much effort to brinfg it to optimum revvs due to the small size and the light weight of the TC) the other bigger TC will kick in at a higher rpm.
So in that way you can enjoy a turbo charged boost through out the revv range.
How much gain a TC will provide will depend on the psi ratings. A TC with a psi rating of 14.7 (which is equal to the atmospheric pressure) will technically increase boost by 100 %. *
