Big O

Is this a realistic setup? 4.73 and boost anywhere from 4psi to 12 psi? I'm using a D series motor/cable l3 tranny. I wanna do this on a 4dr 88-91 civic with lsd and use this as a street/drag setup. Is this too radical a final drive for boost? I searched the final drive and boost but all I found was hydraulic tranny tegs or swapped civics with b series and hydraulic trannys. Didn't yeild definitive results.
Does anyone or has anyone run a similar setup?
thx
