Any difference from 93 to 94?

[Freshmeat]

Long story short, I'm looking at grabbing a 93 to drop the drivetrain into my 94. Can anyone think of a reason this wouldn't work? I know the slave cylinder changed at some point but figure I can use the 93 line also if needed.

The clutch slave cylinder and line for your 1994 would go with your transmission, not the engine, but that hardly matters as both years are the same.

What is DIFFERENT, or more precisely MAY be different is that 1993 Ranger/Explorer 4.0 engines (Except California emmissions) are "Batch fire engines".

SOME (but not all) 1994 RANGER 4.0's are SEFI, with the required (failure prone)
"Camshaft synchronizer" and EGR (which has a failure prone "DPFE" Sensor)

Essentially all US spec 1994 Explorers are SEFI/EGR

So it's important to know what you have before you start your search.

If you have a Non-SEFI truck you can easily swap over the upper intake,
drivers side exhaust manifold, oil pump drive AND on engine injector harness,
from your engine to a SEFI donor engine.

Doing this the other way, ADDING SEFI to a Non-SEFI engine is more of a PITA.

SEFI gives NO power or driveability advantage, was done for supposed emissions reasons
and generally speaking the Non-SEFI engines do better on fuel.

just yankin yore chain.....hope the swap works out good....

Both trucks are Vulcan 3.0 with M5OD. Donor is 4x4, which I plan to swap. I am aware of the work involved with that. My 1994 has serious sentimental value to me so I don't mind the cost/labor involved.

Did you not notice from his info on the left and in his sig, that he has a 3.0??

Odd that Batch fire would be better on gas, since in theory, it seems wasteful having injectors spraying gas when they don't need to. However, MPFI/SFI did have a big power and economy advantage over TBI/CFI.

Don't worry- had someone else asked I'd have offered the same technical support!

 

[Freshmeat]

Beautiful- thanks for that bit!

Now to find my exhaust manifolds...

 

[AllanD]

On a 1993 Vs 1994 3.0 I believe the only difference is EGR on some 1994's

 

[Freshmeat]

Found the exhaust manifolds, still on the Y-pipes! This one is not an external EGR motor so that should keep things simple.
