MJ: Project CRD is born Alrighty, as some of you may or may not know a year ago I finally won the bid on a wrecked CRD. Since 2005 I had been bidding on wrecked CRDs and had been constantly outbid even on low prices(like loosing a bid at $2600). Well I was ecstatic that I finally won the bid, the only downside is that the Jeep was for my father not me. We proceeded to fix the vehicle and drive it out to california for him, he has been driving it ever since and has run up over 30k miles in only a year, the little oiler makes a great vehicle for him. Its repair can be seen here:
http://www.colorado4wheel.com/images...rtyrepair.html Well a little while back now at the beginning of april, and uncannily enough exactly one year after purchaing my fathers Jeep, on my 22nd birthday I purchased an engine that I had found on craigslist. The engine was setup to mate to the NV3550. A plan was formulated and I started looking for an MJ. http://colorado4wheel.com/images/crd...rd_engine6.jpg Now I had been stalking a MJ at my local insurance auction for a few weeks, well everything worked out just right and today I won the bid on it for $850: http://www.klode.com/Kws/Napplicatio...018&Exit=Close http://colorado4wheel.com/images/1988_MJ/MJ1.jpg http://colorado4wheel.com/images/1988_MJ/MJ2.jpg http://colorado4wheel.com/images/1988_MJ/MJ3.jpg http://colorado4wheel.com/images/1988_MJ/MJ4.jpg http://colorado4wheel.com/images/1988_MJ/MJ5.jpg http://colorado4wheel.com/images/1988_MJ/MJ6.jpg http://colorado4wheel.com/images/1988_MJ/MJ7.jpg http://colorado4wheel.com/images/1988_MJ/MJ8.jpg http://colorado4wheel.com/images/1988_MJ/MJ9.jpg http://colorado4wheel.com/images/1988_MJ/MJ10.jpg http://colorado4wheel.com/images/1988_MJ/MJ11.jpg So the project should begin in earnest soon. The CRD engine, with a NV3550 and NP242 will be dropped in. A 4WD front end will be installed, and Dana 44 in the rear. I have the interior/dash out of a 01XJ that will be installed. 97+ doors will be put on as well.(some of these parts to either be sourced cheap from the junkyard, or a parts TJ or XJ). The Chinese Jeep 2500 front ends parts will be installed, and the whole vehicle will be repainted PR4 - Flame Red. Later 16" FreedomXJ/5.9ZJ wheels will be installed and a shell for camping put on the back. Jeep 2500 front end: http://www.colorado4wheel.com/content/Jeep2500.html http://colorado4wheel.com/images/mis...500/stock4.jpg The tail lights will be the overseas 97+ XJ tailights as seen here(as well as the 16" freedom wheels seen here): http://www.colorado4wheel.com/images.../freedom20.jpg |
Nice work, Cant wait to see this finished.
You should start a thread in jeep build ups im sure it will get quite a following. |

I reckon they would have sold well here in 2 or 4wd form against the overpriced Toyota's etc. |

Could a Mod move this to the correct forum?
This information is just for reference right now: Since the XJ uses the older CCD bus and my engine/bosch ECU uses the new PCI bus this means that I will not be able to use the XJ 97-01 gauge cluster. All the important information(engine speed, vehicle speed, water temp, oil pressure etc) is carried on the CCD or PCI. Basically, if you try to use the XJ cluster nothing will work except the basic things like turn signal indicators. So to that end a very nice solution presents itself. The TJ gauge cluster is the same basic size and shape as the XJ cluster, but the newer TJ clusters use the PCI bus. To that end a TJ gauge cluster will replace the XJ gauge cluster in my dash, it will require some basic wiring work, if possible I will de pin the XJ connectors and insert the pins where needed into the TJ cluster. This is the best solution because it keeps the stock wiring intact with fewer splices and therefor fewer places for a future failure to occur. Anyways, here is what will need to be connected for that to work: http://colorado4wheel.com/images/198...mj_cluster.png at the races this past weekend. http://i45.photobucket.com/albums/f9...8/100_1039.jpg http://i45.photobucket.com/albums/f9...8/100_1038.jpg http://i137.photobucket.com/albums/q...8/CIMG0273.jpg More reference information: Quote:

The XJ ACM(Airbag Control Module) is a self contained unit that sits under the center console, there are no crash zone sensors as many other airbag systems have, merely the accelerometer/safing sensor located in the module. There is not a direct connection between the ACM and the vehicle speed sensor, The XJ ACM does use the CCD bus connect, though the wiring diagrams seem to indicate that it connects to the gauge cluster(presumably for the airbag light) and the data link connector(for diagnostic). Regardless I still have some concern that the ACM will need the vehicle speed information available on the CCD bus. This is a problem because the KJ CRD ECU uses the newer PCI bus. If the vehicle speed information is needed for the ACM to operate properly then I will use a XJ CCD PCM(basically a 97-01 XJ PCM) connect the 5V supply, ground, and speed sensor signal back to the XJ PCM where needed, and connect the PCM to switched power as needed. This will then take the speed signal coming from the speedo pickup and broadcast it via the CCD bus. Since the vehicle is getting rewired with the PCI bus for all critical functions the CCD will be a secondary bus system that only contains information for the ACM. So by doing it this way I can ensure that the airbag systems will still remain functional. Quote:
The only thing that prevents the engine from running right now are the ECU and APPS. I have sourced an ECU and a guy in the UK is holding it for me while we find me an APPS unfortunatly for me the KJ I got my ECU out of had the APPS stolen. At worst case scenario I have to spend 100 pounds for a new APPS in the UK. Quote:
So the last bit of engine management stuff I need is an APPS. There is a diesel XJ that I could get the APPS out of, as you can see in the wiring diagram below they only differ by a single pin(which could be moved), the real concern is if the APPS returns the same voltage between the two. (an Accelerator Pedal Postion Sensor is basically just a big POT=Potentiometer) Now I could use a 05+ CRD POT, which indecently is shared by newer toyotas, but it would take a good deal more work to ensure I got the right voltage out of the pot. So for reference: http://colorado4wheel.com/images/1988_MJ/XJ_KJ_APPS.png So even if the XJ APPS does not return the same voltage a variable resistor connected inline could allow me to play around with it so that I got my throttle input right. Well the tow truck arrived today with the MJ, battery was dead so I had to push it up into the driveway. Put the battery charger on it and after a few hours it cranked enough for it to catch and startup. Had the battery charger on all day untill about 6:30, took the charger off, started it once, then shut it off. An hour later I came back and it turned over once or twice and then just clicked. Ran down to sams club and got a new battery, dropped it in and it fired right up. Moved it back and forth a little bit before backing it out of the driveway and going for a quick spin in my culdesac. Drives just fine, brakes feel a little soft. Oil on the dipstick looks about 2 quarts overfilled(way overfilled), right now after it runs for a little bit oil just spits out from around the valve cover. I will drain some oil, degrease engine, and then take a look at things. I saw no evidence of coolant leak when I drove it. Who knows. http://colorado4wheel.com/images/1988_MJ/MJ14.jpg http://colorado4wheel.com/images/1988_MJ/MJ15.jpg http://colorado4wheel.com/images/1988_MJ/MJ16.jpg http://colorado4wheel.com/images/1988_MJ/MJ17.jpg http://colorado4wheel.com/images/1988_MJ/MJ18.jpg http://colorado4wheel.com/images/1988_MJ/MJ19.jpg http://colorado4wheel.com/images/1988_MJ/MJ20.jpg http://colorado4wheel.com/images/1988_MJ/MJ21.jpg http://colorado4wheel.com/images/1988_MJ/MJ22.jpg Oh ya, and the parking brake doesn't work. Also, it was a trip not to find it next to the center console, I wasn't expecting that. Getting closer, got some misc connectors and crap I need to tie the CRD harness into the XJ dash harness, though they are slightly different so I will need to trim the plugs to fit. (they have an indexing tab so you can't install the wrong plug in the wrong place, great when you have 3 similar plugs together, not great when you can only find the one plug) I might check and see if I can get some repair connectors from Jeep that will give me the correct plug so I dont have to trim some off the plugs I have now. http://colorado4wheel.com/images/1988_MJ/MJ23.jpg Some more parts arrived: Hehehe......return home from my early class, looky whats here at the door: http://colorado4wheel.com/images/1988_MJ/MJ24.jpg Now lets get her inside and open her up! http://colorado4wheel.com/images/1988_MJ/MJ25.jpg http://colorado4wheel.com/images/1988_MJ/MJ26.jpg http://colorado4wheel.com/images/1988_MJ/MJ27.jpg http://colorado4wheel.com/images/1988_MJ/MJ28.jpg http://colorado4wheel.com/images/1988_MJ/MJ29.jpg http://colorado4wheel.com/images/1988_MJ/MJ30.jpg http://colorado4wheel.com/images/1988_MJ/MJ31.jpg Ohhhhh purdy: http://colorado4wheel.com/images/1988_MJ/MJ32.jpg http://colorado4wheel.com/images/1988_MJ/MJ33.jpg http://colorado4wheel.com/images/1988_MJ/MJ34.jpg http://colorado4wheel.com/images/1988_MJ/MJ35.jpg http://colorado4wheel.com/images/1988_MJ/MJ36.jpg As you can see its just a normal H3 bulb. I'm thinking H4 Xenons for the headlights, and H3 Xenons for the low beams........hehehehe http://colorado4wheel.com/images/1988_MJ/MJ37.jpg I decided they would look better out in the sun, so I went and took some more pics. Turns out they are way cooler looking out there: http://colorado4wheel.com/images/1988_MJ/MJ38.jpg http://colorado4wheel.com/images/1988_MJ/MJ39.jpg http://colorado4wheel.com/images/1988_MJ/MJ40.jpg http://colorado4wheel.com/images/1988_MJ/MJ41.jpg http://colorado4wheel.com/images/1988_MJ/MJ42.jpg http://colorado4wheel.com/images/1988_MJ/MJ43.jpg http://colorado4wheel.com/images/1988_MJ/MJ44.jpg http://colorado4wheel.com/images/1988_MJ/MJ45.jpg http://colorado4wheel.com/images/1988_MJ/MJ46.jpg http://colorado4wheel.com/images/1988_MJ/MJ47.jpg http://colorado4wheel.com/images/1988_MJ/MJ48.jpg http://colorado4wheel.com/images/1988_MJ/MJ49.jpg http://colorado4wheel.com/images/1988_MJ/MJ50.jpg Snapped some pics under the MJ today: Ew, 2wd, gross! http://colorado4wheel.com/images/1988_MJ/MJ51.jpg http://colorado4wheel.com/images/1988_MJ/MJ52.jpg http://colorado4wheel.com/images/1988_MJ/MJ53.jpg Some light surface rust on stuff, but nothing structural or cancerous. Might try to get it sand blasted instead of wire-brush-drilled. http://colorado4wheel.com/images/1988_MJ/MJ54.jpg http://colorado4wheel.com/images/1988_MJ/MJ55.jpg http://colorado4wheel.com/images/1988_MJ/MJ56.jpg The one part of the body where I will need to do bodywork: http://colorado4wheel.com/images/1988_MJ/MJ57.jpg http://colorado4wheel.com/images/1988_MJ/MJ58.jpg Testing out the 2500 flares, they basically take up the same amount of fender space that the 97+ flares do, but have a somewhat different "squared off" shape to them. http://colorado4wheel.com/images/1988_MJ/MJ59.jpg http://colorado4wheel.com/images/1988_MJ/MJ60.jpg http://colorado4wheel.com/images/1988_MJ/MJ61.jpg http://colorado4wheel.com/images/1988_MJ/MJ62.jpg We will not be able to use the 97+ flare tie downs without modification: http://colorado4wheel.com/images/1988_MJ/MJ63.jpg Bought a parts jeep today, 2001, 48k, and abused: http://colorado4wheel.com/images/200...p/01parts1.jpg http://colorado4wheel.com/images/200...p/01parts2.jpg http://colorado4wheel.com/images/200...p/01parts3.jpg http://colorado4wheel.com/images/200...p/01parts4.jpg http://colorado4wheel.com/images/200...p/01parts5.jpg http://colorado4wheel.com/images/200...p/01parts6.jpg http://colorado4wheel.com/images/200...p/01parts7.jpg http://colorado4wheel.com/images/200...p/01parts8.jpg http://colorado4wheel.com/images/200...p/01parts9.jpg I just want it for the dash/interior stuff to convert the interior of the MJ, I am hoping the paint will come off, if not I will just replace the visible panels. Real shame someone spray painted the interior, it would have been otherwise nice parts. So it will have a number of parts for me to use, plus a 48k mile engine/trans to sell off, plus whatever misc parts. Bought this NV3550 for my MJ today for $550: http://colorado4wheel.com/images/1988_MJ/MJ64.jpg http://colorado4wheel.com/images/1988_MJ/MJ65.jpg As you can see the bellhousing is broken so I got him down by $50, its the wrong bellhousing for me anyways, pictured next to it is the correct bellhousing for the CRD engine. MJ gets some new shoes: http://colorado4wheel.com/images/1988_MJ/MJ66.jpg http://colorado4wheel.com/images/1988_MJ/MJ67.jpg http://colorado4wheel.com/images/1988_MJ/MJ68.jpg Got em for $300 locally, wheels are just about perfect, nar a scratch on them....for now. Got the master/slave combo out of a 96 today, gonna go back on sunday and grab a NP242. http://colorado4wheel.com/images/1988_MJ/MJ69.jpg Here you can see the difference between the 4Liter bellhousing and the CRD bellhousing: http://colorado4wheel.com/images/1988_MJ/MJ70.jpg Got the master/slave, plus a bunch of other junk for $26. Got in my indicator lights, APPS, and ECU. I only need a new injector top and some diesel before I can start this sucker up! http://colorado4wheel.com/images/1988_MJ/MJ73.jpg http://colorado4wheel.com/images/1988_MJ/MJ74.jpg http://colorado4wheel.com/images/1988_MJ/MJ75.jpg http://colorado4wheel.com/images/1988_MJ/MJ76.jpg Quote:
Got me a transfer case out of a 98 today, paid $100 also got the wheel skid plate, and power seat pedistal for a grand total of $130. Not too shabby, I should told him it was out of a 94 and then it would have been $75. Lotsa junk in my garage: http://colorado4wheel.com/images/1988_MJ/MJ77.jpg All bolted together: http://colorado4wheel.com/images/1988_MJ/MJ78.jpg http://colorado4wheel.com/images/1988_MJ/MJ79.jpg http://colorado4wheel.com/images/1988_MJ/MJ80.jpg http://colorado4wheel.com/images/1988_MJ/MJ81.jpg http://colorado4wheel.com/images/1988_MJ/MJ82.jpg http://colorado4wheel.com/images/1988_MJ/MJ83.jpg Slave mocked up: http://colorado4wheel.com/images/1988_MJ/MJ84.jpg http://colorado4wheel.com/images/1988_MJ/MJ85.jpg A limited lace wheel and transfer skid: http://colorado4wheel.com/images/1988_MJ/MJ86.jpg Nothing new, just some pictures of more parts: Not sure if my pedals in the 88 are going to work right for me(at least not without some work), so I grabbed these pedals from a 96 (96 pedals will bolt to the dual diaphragm booster, and my master without issue, and at $10 its hard to complain) http://colorado4wheel.com/images/1988_MJ/MJ87.jpg Now I had already grabbed a clutch master/slave setup, but I found one at the junkyard that is a new replacement, so I decided it was a slightly better part, so once again for $10 I got something that should be a little better: (the original one) http://colorado4wheel.com/images/1988_MJ/MJ90.jpg (and the nice "new" one I grabbed today) http://colorado4wheel.com/images/1988_MJ/MJ91.jpg The dual diaphragm booster out of the 01: http://colorado4wheel.com/images/1988_MJ/MJ89.jpg This is the 8.25 that will be going in there at some point: http://colorado4wheel.com/images/1988_MJ/MJ88.jpg And of course the heated leather seats of out a 01 XJ limited that will be installed: http://colorado4wheel.com/images/200.../freedom21.jpg Got a set of doors off a jeep being parted: http://colorado4wheel.com/images/1988_MJ/MJ92.jpg http://colorado4wheel.com/images/1988_MJ/MJ93.jpg Problem is they have brown door panels.....grr, I have a good black drivers door panel....but no good passenger door panel.......still gotta find one....... http://colorado4wheel.com/images/1988_MJ/MJ94.jpg Ok so these are the engine mounts for a diesel XJ, http://colorado4wheel.com/images/198..._mounts_sm.jpg then here you can see that while the mounts are similar in design, they do not bolt in the same place, rather they set slighter further back in the engine bay, and utilize some different bolts. http://colorado4wheel.com/images/1988_MJ/MJ105.jpg http://colorado4wheel.com/images/1988_MJ/MJ104.jpg Now from what I can see in the pictures of those mounts and from looking at my engine it looks like these mounts might share the engine side bolt pattern, if this is the case then I might be able to get real lucky and just have the motor boltin to the engine bay, boltup to the factory tranny support, and not have to build either of those. If I am not so lucky(which history would seem to indicate that I am not), then I will not be able to use the engine side bracket, in which case using the XJ diesel motor mounts will probably still be better, they set further back and are almost necessary. It appears that trying to use the gasser XJ mounts will actually interfere with things like the AC compressor, Injection Pump, and Power steering. So right now the plan is to use diesel XJ mounts, and probably have to build my own engine side brackets. Now something else has come up, if my ECU came from a vehicle with a SKIM(sentry key immobilizer module) then I will either need to get the calibration reset from my ECU, or get a SKIM and transponder key and have both the SKIM and the ECU reprogrammed via the DRBIII to match. |
