5.2 into wrangler

Hey,
I have an 88 YJ with an 4.2 in it and thought I had bad lifters and cam. When taking head off that doesn't look like the problem. I can either rebuild this motor again or I currently have a ramcharger with a 318 I could swap in. Not sure what route to go. Will listen to any suggestions. Thanks

Easiest method would be to rebuild the 4.2L. Going with FI makes the engine perform even better than the carb.

A V8 swap is a very involved process.

The v8 would be nice but complicated getting the fuel injection working. If you went with a carb 318 it's just motor mounts exhaust and changing the bellhousing to one out of a Dakota with ax15

having the donor vehicle and in running shape is really nice. Cause most folks start with a engine that is already out and with out all the wires and hoses and fuel pump to run it. The run around rewiring every thing under the hood of jeep or buy a harness. Where you can take whole harness from ram IF its EFI,

the v-8 swap isn't that hard, like 88_yj said the wiring can be a pain.
having said that ... there are a couple guys here on the forum that have done it quite successfully. i am a wiring retard so i had someone else wire it up. i think sun devil jeeper and mopar freak both wired up their own 5.2's

however... if i had it to do all over again... i would have gotten an older 350 bowtie and bought the summit efi standalone kit. i would have had exactly the same amount of cash in it and i could have done it myself. the chevy 4500 trans is a little easier to find than the dodge gasser 4500 trans.on top of that, there is a lot more aftermarket for chevy motors than the 5.2 magnum.

The Ramcharger is a carbed 318, not the Magnum 5.2.
My opinion is, it's not worth the trouble w/out EFI.
It's really not that hard to wire in an OBD 1 5.2/5.9.

I have a 5.9 outa Durango rt. Use the entire Durango harness. Used duRango column and gauge cluster. Everything works perfectly, the only two issues I have is that the speedometer doesn't work, as the rear is a sterling , and when you turn the directionals on they blink fast as if a bulb was out. and the airbag light is on

318 out of Ramcharger doesn't have a carb. Uses throttle body and the jeep it be going in uses a carb.

I'd just swap in the V8 but maybe I'm just biased. Iv never done engine work or anything like it. Been doing mine with the help of JF.

You need to either use higher wattage turn signal bulbs, or switch to an electronic flasher relay...
