Yes you can use your G52 transfercase (1984 forward shift style), but you will need to (1) convert it to a top shifter if you wish to mount it behind a 1985-1988 style W56 transmission, or (2) convert it to a late model forward shifter (rods slightly shorter) if you wish to mount is behind a 1989-2005 style W56/W59 transmission. You would be better off just getting a top shifting t/case ('85-'88 EFI 4cyl non-turbo or '79-83 all) which would be a direct bolt-on for option #1.
Or, what you could do instead is use a
much stronger Toyota transmission which would be much better suited for a V8 engine. I am talking about the R151F Transmission found in all 1986-87 Turbo 22R-TE 4cylinder trucks. Not only is this the strongest 5 speed 4WD transmission that Toyota has ever produced, it also uses a stronger version of the gear driven transfercase (stronger 23-spline input). In fact, this transmission is so reliable that Toyota continued using it on the 3.0 V6 trucks as well as today on all 5 speed 4WD V6 (3.4 liter 5VZ-FE) Tacoma Trucks (known as the R150F, uses a different tail housing & transfercase [chain drive]). That's 18 years of service from the R-transmission.
For more information regarding Toyota gear drive transfercases, I recommend reading these two threads:
TC Questions and
dual cses.
I
strongly recommend using the R151F and it's strong 23-spline gear drive transfercase to anyone who is considering either a 6 or 8 cylinder engine.
The Toyota W-series transmission's life includes the Tacoma 4 cylinder 3RZ-FE powerplant (2.7l, 177 ft-lbs torque) and the 1986.5-1992 Supra 6 cylinder 7M-GE powerplant (3.0l, 188 ft-lbs torque).
The Toyota R-series transmission's life includes the Tacoma 6 cylinder 5VZ-FE powerplant (3.4l, 225 ft-lbs torque) and the same year Supra Turbo 6 cylinder 7M-GTE powerplant (3.0l, 254 ft-lbs torque).
This Turbo Supra Engine is commonly tuned to an excess of 300 ft-lbs of torque with little transmission problems.
Also, Toyota offers a factory-installed TRD Supercharger for the Tacoma 6 cylinder powerplant boosting its torque to 302 ft-lbs, and Toyota still guarantees the R-transmission.
The R-series Toyota transmission is a very strong transmission, much stronger than both the G- and W-series trans.
Since a 5.0 V8 has a stock torque rating of 275 ft-lbs, the R-transmission will be more than adequate.
Do you have any major (+200) torque modifications in mind? Like a Supercharger or Nitrous oxide?
