Plede help Link to comment Share on other sites More sharing options...
nitroxsteve Posted September 10, 2013 Share Posted September 10, 2013 Is the 2000 xj also a 5 speed? The rear drive shaft will not work (too short) you will need the have yours shortened. Link to comment Share on other sites More sharing options...
ternest Posted September 10, 2013 Author Share Posted September 10, 2013 The Xj is an automatic. I would love to convert the my to auto but I'm under the asumption that it will be too complicated Link to comment Share on other sites More sharing options...
nitroxsteve Posted September 10, 2013 Share Posted September 10, 2013 1. The rear drive shaft will not work its too short. 2. The front drive shaft may not work because of the difference in transmission length. 5speed vs automatic. 3. The tcase will not bolt onto your 2wd transmission without modifications. You need a 4wd 5 speed transmission. 4. The speedometer drive on the 2000 is electronic your 88 is mechanical. 5. The shift linkage needs to match your transmission as well. Parts of the shifter mount to the side of the transmission. The 2000 may not be the best donor vehicle. If it was a 5 speed and you could get the transmission too then it would help. Also the front axle on the 2000 is a low pinion, it will work but its not the most desirable. I'm sure others will chime in with more info.

yxmj Posted September 10, 2013 Share Posted September 10, 2013 If you are going to do it go all in and change everything...Motor tranny t-case Computer harness...might be less hassle in the end I have both Trucks you do (as well as some more) The motor in that 2000 is the best 4 liter made...off the shelf 25 hp more that your 87 (with potential for more) Link to comment Share on other sites More sharing options...

I am assuming that year must have come with both the better head (7120?) and the octopus intake, correct? Other than that what was done to improve performance? :hmm: Link to comment Share on other sites More sharing options...
FrankTheDog Posted September 11, 2013 Share Posted September 11, 2013 It has 13 more HP, 1987 was rated at 177. 2000 was rated at 190. Link to comment Share on other sites More sharing options...
yxmj Posted September 11, 2013 Share Posted September 11, 2013 My info has the 87 @ 170 and the 2000/2001 @ 195 My right foot and backside can tell you that there is a very noticeable difference going from my 88 2 door Laredo 4l XJ to my (wife's) 2000......You can even notice the difference from my 1998 4l XJ to the 2000. The only enjoyment I ever get out of driving the wife's XJ ( because it is Sienna pearl in color and has flowers hanging from the rear view mirror.....and she won't let me lift it) is the look on the faces of the tuners and 5 liter mustangs ....when I leave them at the stop light. Just for some good reading look at the car and driver article (****** I will preface this to all the Keyboard warriors.....I did not write it ....just posted it****) Makes me want to run from the cops.. . :MJ 1: . When the 4.0 burst onto the scene, it had a full 180 horsepower in the Wrangler (a German publication listed it as 172 horsepower, and, in the Cherokee, it started out with 170 hp). One of its advantages was being designed for fuel injection: it had no mechanical fuel pump and was intended from the start to be injected, developed with help from Renault’s fuel injection techs (it used the Renault-Bendix, or Renix, system from 1987 to 1990) In 1990, when the 4.0 still had 177 hp, the GM 4.3L V6 only made 160 hp, the Ford 4.9L I6 (used in the F150 and Econoline) only made 145 hp, the Ford 4.0 V6 made 155 hp, the Chrysler 5.2L made 170 hp, the Jeep/AMC 2bbl 360 V8 made 144 hp, and the Nissan 3.0 V6 (used in the Pathfinder) made 153 hp. Jeep upped the ante in 1991, when the Cherokee's version made 190 hp. In 1987 I wondered why they didn't drop the 4.0 I6 into the YJ, which was still using the 112-117 hp 258 (4.2 liter) six; or the Eagle, Concord and Grand Wagoneer, which came with the four-barrel 360 V8, making just 144 hp. The 4.0 made more power than the Ford 302 V8, Chevy 305, Chrysler 318, and AMC 360, as well as any of the six cylinder engines the Japanese were putting in their trucks, and it had comparable or better fuel economy. An AMC Concord with the 177 hp 4.0 I6 might have been a better police pursuit vehicle than the Dodge Diplomats (140-150HP), Chevy Caprices (160-170HP) and Ford Crown Victorias (160-165HP). Compared with other contemporary engines, the 4.0 was strong up until the end. Link to comment Share on other sites More sharing options...
ternest Posted September 11, 2013 Author Share Posted September 11, 2013 I'm guess I'm just looking for the easiest bolt on application with as little modification as possible. The only reason I suggested the 2000xj is cause the parts are free. The motor on it has a blown head. And for the gears I have a buddy with 4:10s for me Link to comment Share on other sites More sharing options...
yxmj Posted September 11, 2013 Share Posted September 11, 2013 Then you would be better off finding something closer in years (87-90 ?) And just to clear up a point made above....you can't modify a 2 wheel drive trans to bolt up to a t-case....you will need a 4wd one Link to comment Share on other sites More sharing options...
ternest Posted September 11, 2013 Author Share Posted September 11, 2013 so i need tranny tcase linkage and driveshafts that might not fit? Link to comment Share on other sites More sharing options...
yxmj Posted September 11, 2013 Share Posted September 11, 2013 If you take the trans t-case and front axle off the same vehicle (XJ?) then take the front drive shaft and linkage as well.... all will bolt up. You will have to have a rear drive shaft shortened and re-balanced. My tip would be leave the rear drive shaft for the very end....not only will it be easier to measure to get it right.....but if everything else is installed you can put it in 4x4 and drive around in front wheel drive ( you might have to put a plastic cap on the t-case output to keep fluid from running out.

nitroxsteve Posted September 11, 2013 Share Posted September 11, 2013 If you can get the parts for free get them. You may be able to trade for correct parts. Link to comment Share on other sites More sharing options...
ternest Posted September 16, 2013 Author Share Posted September 16, 2013 How much of a pain is it to convert the 87 to an automatic? Link to comment Share on other sites More sharing options...
yxmj Posted September 17, 2013 Share Posted September 17, 2013 As long as you had access to the computor and wiring harness as well as the drive shafts and linkage from the vehical it is coming out of...it is not impossible Link to comment Share on other sites More sharing options...
ternest Posted September 22, 2013 Author Share Posted September 22, 2013 Ok found a 97 that I can get the parts out of why is it important that I get the computer and wiring harness out of it? Link to comment Share on other sites More sharing options...
