There you go. I inserted the missing words

And,,, don’t swap you brake booster until you go through the list to check your brake system first. Just my $.02

Yeah I ran a relay harness for a while on a really nice set of sealed bulbs and it just wasn’t cutting it for me. Went with morimoto projectors and haven’t looked back

Although the JK30 is a bit of an upgrade over an XJ30 in stock form, both axles can be modified to death. By the time you do all the mods (truss, gusset, shafts, locker etc) you’ll be in it for more than a good HP44. That being said, a built xj30 and jk30 are not that far apart when it comes to what they can handle. It’s not a very big upgrade unless you are only comparing stock-to-stock specs.

And don’t discount regearing your existing axle. The Ford 8.8 is a boat anchor for 33’s. The 8.25 liberty is a very nice choice. However, since you have to reheat your front axle to match, you can often get a decent deal to do both at the same time. What engine and transmission do you have? That will make a big difference as to what gears to go with. I have a built 4.0 with the auto tranny and run 4.56 gears. I could have easily gone with 4.88 gears also and been fine. The point is, you won’t find many stock axles in those ratios so a regear may be in order for whatever you decide to get. If money isn’t an object then have Currie enterprises or east coast gear supply build you a pair of axles. If you want to be more frugal then perhaps settle for 31” tire and about a 2-3” or so lift. That along with a good set of flares will let you keep stock axles (still don’t get too wild with them), and mostly stock suspension/steering. Will be a nice daily driver rig with decent off-road potential. If you do regear a dana 35 just keep in mind it’s limitations. They typically brake an axle shaft first so upgrading to 27 spline axle shafts that are built from a stronger and more forgiving materialI will give your axle more life. A truss (I run a model from TNT) will strengthen your axle tubes a stiffen the axle overall. If you have a pre-1990 dana 35 then they have bolt-in axles and are decent little axles but not nearly as strong as the Chrysler 8.25, Ford 8.8, Dana 44 or AMC 20. Even those axles have some models that are not very desirable. I guess you could say it all boils down to tire size and budget as this really determines everything.

The gauge provision on the back of the head should be 1/8npt as is the oil pressure sender. The ecu doesn’t need either of those signals. You can go with a large variety of units. If you want to go with a stock setup then go with @jdog’s suggestion. For aftermarket, you can grab an a pillar 1 or 2 gauge pod for an XJ from autometer and install 2 1/16 autometer gauges with senders. I do find the autometer route far more accurate than a factory gauge but that’s just my $.02

Regarding brakes, the dual diaphragm swap is a good one as Pete mentioned. If your interested, there is a thread in this section regarding where to start first with the brakes that may be helpful to you. Although most will say to waste no money on the Dana 35 rear axle that is likely in your Jeep, I have been running one for several years now with 4.56 gears, upgraded axle shafts, a small truss (to stiffen the axle housing and tubes) on 33’s. Works very well for me and I have a lot more clearance under the axle than any other rig on 33’s. I wouldn’t recommend going any bigger though. Tire width also plays a factor in how long these axles last.

I’d like a pair also

In my opinion (pulled and installed about 6 of these setups), I prefer installing the engine and tranny together. That way you can ensure simple things like your cps and bellhousing alignment are spot on before installing. I always put the tcase on separately since they are really easy to install under the truck. Just get a ratcheting box wrench with a swivel for the tcase to tranny nuts. I’d pull the tcase for removal as well. With the radiator crossmember pulled it’s a fairly straight shot and I’ve never needed to jack up the front. Just my $.02

https://www.summitracing.com/parts/wil-330-9371 This would probably work just fine. There are many other options but I’m partial to Wilwood. Lokar makes a great set also that has more adapters in the kit also. Both of those kits are cut to length.

Stock MJ e brake cables can be made to work with that setup (slight modification required) or you can run TJ cables as I believe that is the setup for them. Personally I’d just grab a set of universal cables in the correct length. It will come with various ends so you can get exactly what you need. I believe the TJ cables are a bit short if you have a long bed.

I’ve been running 95% water along with water wetter for corrosion inhibition. Essentially it’s a racing coolant setup. No worries about freezing here ever . Works well but still gets too hot. The new injectors and timing advance should straighten that out.

Can you send a picture of the back side of the brake backing plate? That we we can know what the connection should look like

It is my belief that the largest core currently available is the Novak radiator. It is 3” thick (dual 1.5” cores) and has no tranny cooler provision. I really like this radiator but can’t seem to get Novak to answer my emails (hard for me to call them during their business hours form here). The old style Griffin radiator seems to be great but isn’t available anymore. Their new one is just a 1.5” core. My current core is 1.5” although the end ranks are a full 2”. Once I get this fueling issue straightened out I will move on to the radiator if needed. Planning on advancing my timing a few degrees also which should help everything a bit. I’ve really been kicking around the idea of getting a Holley Terminator X system and just removing this obd1 system all together. By the time I invest in a good afr gauge and fpr I will be half way in to getting the Holley system. It always surprises me how much is available for the renix Jeeps vs the OBD1 years. Obd2 is nice and there will be an adapter for obd1 vehicles to run an obd2 ecu as plug and play (see pic below), but after buying the ecu, adapter and HP Tuner your in for the same price as the Holley setup.

You got it. Send me a PM. My new injectors should be installed by Monday/Tuesday

Found the issue for the lean running. I have 19lb injectors not 24. Finally dig up the receipt and these are upgraded stock injectors only. Just ordered up some Ford Motorsports purple injectors which are a 6 hole true 24lb @ 39psi.

Thanks but if you read the other posts you’ll see this engine has no rust internally (it’s been checked, flushed, checked, flushed x10). It’s not the original engine. 96 block, Bored, camed, aluminum head, roller rockers, hylift Johnson lifters, hypereutectic pistons, cometic head gasket, .038 quench, shaved block, flowkooler water pump, new crank, king main and rod bearings, arp main, rod and head bolts etc etc. My main question is regarding the pic of the plugs above now to know if it looks lean (it does to me but would like some more feedback). I think I’ll have to post the plugs in a separate thread for replies.

I have one from my 91. The pump leaks but the bottle is good.

Let me get your feedback on these plugs I just pulled. Cylinders are laid out 1-6 left to right. I feel a May be running a bit on the lean side. I do know my fuel economy is quite good. Uploaded in full resolution so you can zoom in

So, to get get back on topic. What’s the best radiator/fan setup made for XJ/MJs

Yeah, the problem is limited availability and shipping due to where I live. I would like to give it a try though. Have you tried it?

No I don’t. Not a bad idea but would be a supplement once I get the coolant temps down.

I believe he’s referring to racing type coolant which is pure glycol. It’s supposed to be some really good stuff. I’ll see if our one racing outfitter has any otherwise I may be able to order some and send via ocean freight

No, but we don’t have access to any here anyways. The radiator/fan combo simply can’t keep up with the engine when under load

I’m guessing most of you haven’t seen my build thread. Suffice it to say, no expense was spared on the engine build. Its got about 15k on the clock since the build. I’ll set my temp sensors on the radiator inlet and outlet and see exactly how it’s working. It for sure the radiator though. I’ve had oem, csf and now am running a 2 row all aluminum unit. Flowkooler water pump, genuine Mopar thermostat, Edelbrock head which does heat up the coolant a bit more. The engine is bored, high compression, camed ect. 24lb injectors and fuel pressure is spot on. Air temp sensor relocated to air box to richen things up also. I’ve been toying with the idea of a stand alone efi setup though. Richening it up a bit would cool it down for sure but it’s not running lean now.
