JDM Switchable T-Case question
 

I have a welded center diff, and a switchable transfer case.

The car is basically underivable in tight cornering situations (parking lots)

I know I can go under the car, unbolt the retaining plate, let the "plunger" slide forward to get 2WD.

Thats great, but I want more!

I want to be able to switch from 2wd to 4wd (back and forth) in the cab, but I want to do this without damaging the transfer case (because they are so rare)

I plan on building a bracket and a cable (or use an electric solenoid)

but I need to know:
1. How strong do I need to build the shifting mechanism
2. How much slop can I have, is the answer in thousands of an inch or "close enough"
3. can I switch while driving? (probably best to do it in a slight turn, so whatever "syncro" or "teeth" that make this thing work, can align themselves)
4. am I going to blow it up? (my car should dyno in the 400WHP plus catigory)

Thanks

Since these are so rare, I think those are mostly questions you will have to answer for yourself. I don't know of anybody else on here that has had one.

So do you have the switchable tranny too? Supposively I have a switchable JDM Galant VR-4 Tranny, but I don't know how to tell if it is or not... But I kind of think they are a big urban myth.

No, they are quite real, you need a switchable transmission -or- a welded center diff to use the switchable transfercase.

there will be a 2WD/4WD sticker along with a lever on the side of the transmission, if it isnt there, its just a stock transmission

Re: JDM Switchable T-Case question
 

I would think if you are not moving it would work just like its supposed to, move the lever out to release and back in to engage(or what ever it is). I would just make sure its held really good when you are AWD, there might be some force trying to disengage it while driving, possibly.

My plan is to get the car up on a lift, get it idling correctly, put it in 1st, and see what happens when i unbolt the plunger.

Aside from possible VC boot damage I do not see what that would show you....
