I had it on my MJ years ago, with the 6.5" lift the drag link was too short and needed lengthened, otherwise it all bolted up and went down the road ok. It's pretty light duty though, I was surprised that It held up as well as it did.

Another wonderful swap
mnkyboy replied to JustaValiantguy's topic in MJ Tech: Modification and Repairs
When I was gathering parts for a 4.3l i was wanting to do an NV3500 5spd with a 231. It would have fit pretty much the same as a stock trans, they shift pretty nice, and are drivers drop. -
XJ and MJ front stiffeners are the same, the mid stiffeners back are different. Basically anything past the cab support under the door will be completely different.

your favorite MJ mods: go fast edition
mnkyboy replied to Pete M's topic in MJ Tech: Modification and Repairs
Not sure, I haven't got it on a dyno. Even turning 37s It is significantly faster than stock, my 4.0l 5spd XJ feels pretty weak in comparison. -

mnkyboy replied to Pete M's topic in MJ Tech: Modification and Repairs
I'm gonna go with my MJs dual transfer case set up, as long as it can get traction the truck will drag pretty much whatever you hook to it, my XJ in low range feels incredibly weak by comparison. -

Not much of an update but a while back I noticed my oil pump had broken causing a bad distributor wobble, I swapped the Melling M81 for a cheap aftermarket pump. I haven't been too happy with the new pump, it doesn't like to build pressure at start up, it builds pressure if I rev it then loses again pressure at idle, i think the relief is screwed up. After some looking around i picked up a Melling M167HVS which is a variation of the Melling M81AHV high volume pump, I figure if I have to tear it down again I will upgrade. The pump is not listed to fit a 2.5l but since they fit the 4.0l and 4.2l I know it will bolt up, so the issue will probably be pan clearance. I reckon I'm gonna find out, shouldn't be too hard to make it fit. The pics are the new high volume pump vs. the old M81- 798 replies

You could drill through that extractor with a rescue bit or similar tool to remove it.

Drill the plug and pick out the pieces, then use a Time-Sert kit to repair the threads. Just use lots of compressed air and a magnet to get as much metal out as you can, it sounds kinda sketch letting a little metal into the combustion chamber, but I've repaired dozens of heads like that with no issues.

Externally regulated altenator on '90 Comanche
mnkyboy replied to atxg3's topic in MJ Tech: Modification and Repairs
Do some research on converting it to an external regulator, there's lots of write ups and even several You tube videos on how to do it. It's a pretty common swap on the newer Jeeps, when the one in the ECU dies, it is a lot cheaper to convert it to external rather than buy a new ECU so lots of people go that route. You can find kits online or piece it together yourself to save a few bucks. -

It probably was me. Might be a while on a update on the standalone,Friday I am going in for another knee surgery so it might be a bit before I get to tinker on the truck.- 798 replies

It's not uncommon for one or more valves to stick on an engine that has sat a while, many times I've worked the valves with a mallet and got the compression back. I would be looking at the valves first as Eagle suggested.

Thanks. Right now Speeduino seems comparable to the early days of Megasquirt as far as information and support stuff, it took Megasquirt a long time to get were it is and I imagine Speeduino will get there too in time. The 4.0l looks to be a little easier to set up since it's already supported by Speeduino but so far no one has done anything with the 2.5l Tuning should be about the same since both use tuner studio.- 798 replies

Adjustable control arms or drop brackets?
mnkyboy replied to OldSch88L's topic in MJ Tech: Modification and Repairs
Either will work, drop brackets will ride better. Doing both adjustable arms and drop brackets will work the best. -
AX5 fifth gear and AX15 fifth gear
mnkyboy replied to eaglescout526's topic in MJ Tech: Modification and Repairs
I doubt any of it would swap, besides .85 vs .79 isn't much of a difference. If you did anything, I think you would be much better off just putting an AX15 behind the 2.5l -

My distributor has had a nasty wobble to it for a while, i finally dug in and found the issue. Besides the broken pump drive, i found that when i put in the new pump it was having binding issues similar to the old pump, i pulled the locating dowel and found it was damaged and looked like it had been installed incorrectly at some point, i swapped in another one and the new pump turns nice and smooth.- 798 replies

91-92 are Chrysler MPFI so a Renix 428/429 ECU wouldn't be any good there either.
-
I don't see how it could, besides 4cyl vs 6 cyl the Renix 4.0l is MPFI and the Renix 2.5l is TBI. Unless you found a 2.5l TBI 429 ECU, I'm not sure if they used that part number on the 2.5ls though, typically it's associated with the 4.0l.

My current wheels i shot solid black,the plan was to sand down portions to reveal the silver underneath but i never got around to it. My last wheels i shot red & black, i thought it looked pretty good.
