92 2.3 swap to a 97 2.3 ?

Hey guys Ive been running this ranger for a while knowing its on its last leg, and after getting compression of 120 on cylinder 4, 30 on cylinder 3, 15 on cylinder 2 and 80 on cylinder 1(not to mention adding oil in the cylinders and re-checking all the compression went up at least 20psi and cylinder 1 went up 50 psi) I've decided that replacing the engine will be the cheapest easiest way out. I found an engine out of 97 that looked good with no leaks and had around 120-140 psi in every cylinder, so I got the engine ready to pull out but before i pull the engine and swap it in I'd like to make sure that it will work in my 92 without swapping the wiring harness and computer. I'm going to use the 92 intake, vacuums, exhaust and what not but the main thing I think are going to be crank sensor and major things like that. thanks guys any input and help is much appreciated.

they use different intake manifold set ups and different injectors, and i noticed a coolant sending unit was plugged on the new one but I'l just swap the plug for the sensor. I just noticed the crank position sensor is setup different but wanna make sure it can be changed over to the old style.
Thanks tho

you might run into some issues...the 92 is OBDI and the 97 will be OBDII...that very well might present a problem

yes but the OBDI and OBDII deal mostly with the intake and injection, but as long as the engine blocks are set up the same all the old parts should swap over. No one has done a swap like this before?

after some further research ive learned that the engine block itself is nearly the same the only problem is the crank position sensor. You have to use your old crank pully and timing cover and mark holes to mount your crank sensor, then drill and tap. its easiest to use your old intake also and use your original wire harness and everything will work. . . hopefully. I'm going to try to get most that done today, but I still have to do a few things to get the old motor out.

If the engine block is the same, you can swap over your OBDI stuff and run it as OBDI. OBDII just has added sensors that monitor more things, aka more problems.

PS, do some research and you actually may be able to use the 97' crank position sensor. As long as the timing marks are the same, and the read outs are the same you won't have to mess with drilling and tapping. Just make sure you rewire it correctly to the ECU.

Welcome to the forum

No, it will not work

1994 and earlier Ranger 4cyl engines can not be swapped into 1995 or later Rangers, and visa versa
Front of the engine is different
