What ratio is the diff in your 131 now ?
To know that will tell us what differences you will see. Find out what that is & let us know.

My 131 had a diff ratio of  3.58 : 1 & I replaced it with a 3.55 : 1. Very little difference & not able to notice any change to acceleration or cruising. The odometer was able to be brought back to reading correct by choosing another aspect ratio rear set of tyres.

Sid, what ratio did you use with that Toyota diff in your 131 ?

In present i have 131 diff with 3:9 thAt is very good to me but with the 132 diff there is only 3:7 or 4:1 . I have 3:7 and i think is good for accelaration with some tuned engine and smaller profile tyres

[POQ 131]

3.7 :1 Should be good. Like I said, I have 3.55 : 1 with a 2 litre 5 speed.
Smaller profile tyres like you say will bring you to somewhere between the two ratios & closer to what you had.
