2.3 Turbo Tranny

[AllanD]

Do you really believe that the turbocoupe clutch is bigger?

It isn't.

The Merkur turbo clutches are exactly the same diameter and spline
as the ranger clutch.

the T-bird turbo clutch only has a different spline on the disc.

the pressure plate may be have a weaker diaphram in the ranger,
but that's EASILY corrected by using a 2.9 pressure plate.

Frankly if I were actually actively building a turbo ranger I'd definatly build
it with a Mazda and I'd put a centerforce clutch on it,
one spec'd for a 2.9.

I frankly won't build a turbo ranger in a 2wd so 4x4 is an absolute necissity
and I prefer parts that are easily aquired.

After much thought I want to put a gen1 cab onto a Gen4 rolling frame,
because I've half decided to make the thing AWD rather than 4x4.
I believe the '98-up 4x4 stuff is better for "ON highway" use anyway.

and bigger brakes is always a plus.

You stole my idea!!! I think it would be awesome to do a 2.3T AWD Ranger out of a SLA truck, but I don't know if you could mate the AWD t-case from the 5.0 Explorer's to an M50D...

 

[skyy_4life]

actually i have been planning making my 94 AWD for a long time using a exploder T-case but idk how much work it would take with differentials and stuff so i was going to find a 4x4 ranger and bolt up a AWD exploder T-case.... hmmm

The AWD Explorer T-case simply won't work, because the 5.0AWD uses
a 4R70W (the all electronic AOD) trans and it uses the F-series T-case
flange and spline (six bolts)

while the Explorer t-case with it's rigid steel on steel REAR output and it's viscous coupling in the path to the front output would be "ideal" it can't work unless someone makes an adapter that allows full size T-cases on a RBV 5-bolt flange.

the T-case I was thinking of using was the Dana TC28 AWD T-case out
of an Aerostar, this WILL bolt to an RBV T-case, but driveshafts are going
to be pretty much a custom proposition, as the TC28 uses a slip yoke rear
output which is the same as an A4LD/4R55E/5R55E.

The front output is aalso a slip spline similar to that on a 13-50 T-case.

The Aerostar uses a planetary centerdifferential that splits
torque 70% Rear 30% front mechanically and uses a seperate
wiring harness to connect to it's speed sensors, one for each output.

above 5-8mph and below 55mph the T-case will lock for 3seconds
(BIG electromagnetic clutch) when the control module detects a
5-8mph speed differential between the two outputs.

the reason for the upper speed limit is that a 5-8mph speed differential
can be created at higher speeds just by negotiating a fast corner.

The control unit needs inputs from VSS, PRNDL, BOO and it's own
two speed sensors.

This is most emphatically NOT an "offroad" T-case.

See? I never thought about that one... So that makes my project probable Man, I wish I could do that right now... That would so kick butt...

I can verify this for a fact. The Centerforce clutch in my Ranger came from a Merkur that blew a rod 10k miles after he put the clutch in. Paid $75 shipped on ebay for it.

 

[skyy_4life]

wow if u find another centerforce clutch for cheap u need to pm me.... hehe

 

[pocket-rocket]

It's a regular Centerforce though, not a Centerforce II or Dual friction. Just pop on ebay a few times a week man

 

[skyy_4life]

thanks im going to have to look around on there.

the m50d or what ever it is has been holding 19-20psi and broke 3 rear ends in our BII.
