This cannot be done
The R trans has much wider gear set spacing to accomodate the larger bearings and wider, bigger gears to handle the added torque of the bigger engine.
Everthing in the R is bigger, longer, and stronger.
I have converted many 88-92 3.0 V6 R150F (3.83:1 1st gear) to the 4.31 turbo gear. Both the countershaft and 1th gear must be changed.
