Topic: dual cases question

[dieselsmoke]

I have the g52 trans / t case is my truck now, I also have a w56 trans / t case, when I put the 5.0 ford engine in I was planing on putting the w56 behind it, from what I have read here it is stronger than the g52, with that said my question is can I use the t case from the g52 to set up a dual case ?

I realize my driveshaft lengths are going to change I was thinking about the the CV joint shafts on marlins site, that square front drive shaft looks cool also

I would also be able to use the twin stick in the rear case

you need two gear driven 4 cyl transfer cases, both of the ones you mentioned fall in that catagory

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?

not just yet, the 5.0 that I have is in a crown victoria, it has just over 100k on it, I built the engine for my mother years ago, the engine runs like a top but the body needs way to much to bother with so I plan to snatch out all the good parts and send it to the bone yard, I was going to change the cam and lifters to a stock 5.0 mustang 225 hp and get the edelbrock pro flo fuel injection system to put on it, that with headers, true duals and some other tweeking should get me closer to 300 hp

I plan on building a 351 stroker for it ( 454 CID & well over 700 hp )  later but when I do that I will put a NP4500 behind it with a NP205 t/case thats gonna cost about 15 to 20 grand

as for my t/case question if I can put the 84 case behind the t/case on the w56 I would just make it a top shift and use the twin stick

I'm not sure of the age of my w56 it has the vent in between the shifters and has a speed sensor so I figured  mid 90ish my 91 still uses a cable

one thing I should add about the edelbrock pro flo fuel injection system
1) it DOES NOT require a lap top to program
2) it is complete from plumbing to wiring harness
3) comes with its own distributor and ecm
so this system covers everything you need to hook up your v8 conversion at a performance level for both ford or chevy

I just put one on a 454 BBC that I built for one of my side customers it puts out 545 hp and runs like a cat on fire

I have a 91 toy that will get this drivetrain when my 86 gets the stroker

thanks for the info

Cool, sounds good! If you can, keep us updated with a couple pictures every now and then. This would be neat to see

what parts will I need to put the cases together, I know I would need the mco8 adapter plate but what about the output/input is their a coupler or do I have to change out the gears,

also what about changing the ratio,

I'm thinking I have 2 trucks so...

I figure when I build the stroker motor with the NV4500 to go into the 86 then the 5.0 will go in the 91 so I can have a mud truck and a rock truck

then I will be a real redneck cause I will have a 20k dollar 4x4 and a 40k dollar 4x4

I will try to find an r151 for it as well
