Here's the duration based on the Toyota literature comparing and contrasting the 7M to the 2J
Exhaust NA 236
GTE 236

Intake NA 226
GTE 236

Utilizing Jeff's info on Lift,
There are 5 cam part numbers for the Supra, take from this message whatever you want, heh:

Intake:
13501-42020 - 86-87 N/A Intake Cam (38.36mm Lift (I think, I'm not 100% sure on that, can someone with an 87 TSRM check that for me?))
13501-42030 - 88-92 N/A Intake Cam (38.16mm Lift)
13501-42010 - Turbo Intake Cam (38.35mm Lift)

Exhaust:
13502-42020 - 86-87 N/A Exhaust Cam (38.36mm Lift)
13502-42010 - 88-92 N/A Exhaust Cam & Turbo Exhaust Cam (38.35mm Lift)

I have no duration information though.

From this I gather, Turbo cams are the same for all years. 38.35mm lift, 236 deg duration
Provided Toyota didn't muck around with duration for the different NA cams, then you have three options.
1) 86-87 NA Intake cam 38.36 mm lift (maybe) and 226 deg duration.
2) 88-92 NA Intake cam, 38.16 mm lift, 226 deg duration
3) 86-87 NA Exhaust cam 38.36mm lift, 236 deg duration

The only one that has better numbers than your stock turbo cams is the 86-87 na exhaust cam. You gain one hundredth of a milimeter of lift....
Not worth it IMHO

I've got the N/A cams and I can't say there's any proof either way. I didn't have a before comparison at all.

woot for .01mm lift.
