I have a 96 GC, and from what I am reading... this should be pretty easy overall. I dont need to do the Power steering mod, and the only mods I might need to do are lengthen some of the hoses? am I right?

I did. I ended up capping the nipple and making an ever so small little slit in the cap.


Idle went back to normal and no other problems

another intake swap.

I have just a few more items to collect for the swap! I got a '96 PS Pump and brackets this week, I still need the new belt. I also need to clean my 703 injectors, intake, TB and IAC. I am finishing up my rear end CA replacement, BB, Bilstiens, Prothane bushing & 3" exhaust. I had to take a few days off from the build, but will be back hard on it Monday.

So the 96-98 zj is easier to work with...good. So the manifold can be taken from a 99wj or 99xj? I put in some upgraded injectors and the manifold would be a nice little addition for getting my max mpg outta the new ford 4-hole injectors I have...

How long does this take to do? And anyone have the upgraded injectors, electric fan and 99 intake manifold? What would that get for gas mileage, or what does it get?

The 96+ is easier as it already has the correct power steering pump/bracket.

Donor's are 99+ WJ/TJ/XJ..

Install time will depend on who's turning the wrench, i'v done numerous headers etc so I was familiar with the job. MPG is going to vary.. if you see an increase at all. The typical advantage of this swap is improved idle and throttle response, if your looking for a mileage increase you will most likely be disappointed.

I had the same issue as Torchd.. until I swapped the check valve around.

FYI - anyone in CA wants to do this, it is CA smog legal.

The tech wont notice the difference and it wont mess up your numbers. After I fixed my smog issues the truck blew a hair above the minimum on all numbers, HC, NO, CO, etc.



Question, are the 96-98 pumps different than 93-95? I did this swap many many moons ago, and now my power steering pump is leaking. I need to change it but I cant remember what pump I used..I do remember swapping it out.

The 93-95 pumps are different than the 96-98. When I did the 99+ manifold swap I changed my pump out for a rebuilt pump. Told the parts guy to look one up for a 97. Hoses from the 93 fit the 97 pump just fine.

The 93-95 pumps have threaded holes on on the pump body because they are bolted front and back to the brackets. The 96+ pump has straight drilled holes because the pump is sandwiched between the front bracket and the intake manifold, with long bolts that screw into threaded holes int he manifold.

I think someone re-used the 93-95 pump doing this swap by drilling open the holes on the pump to allow the use of the thru-bolts.

Someone did do that but the older pump is also a hair bigger than the later pump so he just kinda got the bolts going and let the threads jam against the older pump. I also think he was only able to get two of the bolts threaded. It worked, but I wouldn't want to have it that way if you ever have to take the pump out and back in more than once. Gotta get the later model bracket from the JY anyway so might as well grab the pump or take your chances with a rebuilt pump.
