93 ranger 4.0 into 91 X ??

[Tbars4]

i need some good quick advice here.... a guy i know has a 93 ranger 4.0motor without the harness and i need to know if i could put it into my 91 X as a straight swap???...Mine also is a 4x4, does it matter at all if his was 4x2??? is there anything I should look for going from a ranger to an X???

the only advice i had gotten before was to make sure i got a 91-94 4.0 motor as there was something to do about they wire up different...

thanks for all the help...

anbody??? i only ask this as i am not sure, if for any reason a ranger motor is different from the X, as i think they wouldn't be...

 

[Tbars4]

ok, i just found out the motor came out of a 93 ranger manual tranny and it has all the wiring... it is going into a 91 X w/auto tranny...should there be any problems of just plugging it in or will some wire swappage need to be done??? i have read several threads but can't find any problems with the quick swap so far, anybody???

I did this. You should have no probs. You will even be able to use some of your wires.

 

[Tbars4]

burns...what im thinking is, just unplug my x's motor, pull it, drop in the ranger motor and plug it in...is it really that simple??? even with different trannys???

 

[Burns]

Yes. That is what i did. Even if the motor is from a 5speed truck or auto. Also does not matter if it is 4x4 or 4x2. I pulled my motor out of a 94 ranger 5speed truck and put it in my 91 auto explorer.


I unpluged every wire on the new motor and plugged it up with what was in my explorer.

 

[Tbars4]

that is to cool, lmao...thanks so much for making my day...

 

[Burns]

LOL. Its was one of the best things i ever did to my explorer. I had 319,000 miles when i did the swap.

Its a pretty easy swap. Here is a tip for you. Dont try to pull the exhaust manafolds off if you dont have to. I broke two bolts off in the newer motor and had to drill and tap them out. Just a warning for you.

 

[Tbars4]

thanks for the tip...now that leads to another question...the X has headers on it...should i keep them??? i was told it got killer gas milage before he seized it and was wondering if headers are a bad thing on a 4.0???

 

[Burns]

Ah well then swap the headers on to the newer motor. I will prob get better mileage with the new motor. Mine did. I would keep the headers.

 

[Tbars4]

better mpg's, more power, gruuuunt...lol thanks burns...
now i'm sketching....
if i didn't have to work this week i would work day and night to get this ready for pismo...first, i can't get it home till next weekend though...but it will be running for say a trial run in big bear in july??? just fishing that is, lol

 

[Tbars4]

its official for the motor...i just got the used one delivered and it did came with the harness and a computer...we'll keep this thread updated as for the motor swap but i have faith in burns' info...
