There is also a DMTL pump, I think mounted to the frame, and the fuel pump is different, and probably the wiring harness is a bit different.

I'd probably just toss the 4.6 in without the SAI computer and crap. If you're doing head gaskets, you could take the heads off the 4.0 so that you don't have to plug the holes. If you use all the 4.0 computers, you don't have to worry about syncing anything up, most likely. Doing an adaptive values reset might not hurt though.

The computer should be able to adapt for the change in displacement with the MAF and the o2 sensors. You might want to use the air hose and MAF from the 03.

 

oh, yeah. good call. forgot about that little guy.

 

The intake hose on the 03 has a "box" attached to it that doesn't appear on my 00, so I planned to just transplant the whole thing.

I have no idea what a DMTL is. Data mining Tattle Lump? Well, whatever it is, I'll swap that over, too.... More complicated than I hoped.

I updated my last post before I read this--sorry about that. I'll have to read up on SAI, but since I am replacing head gaskets anyway it would be no big thing to just put my old intake on the 03 engine.

 

Here are pictures of the donor:

As you can see, my cat nominated the recipient vehicle.

 

Quick update.

I started the teardown from the bottom up. Got exhaust and driveshafts off. It was a pleasure to cut the crossmembers when all of the bolts rounded. I took a lot of interior parts off too. The 4.6 is on stands to give me more room to work.

The transfer case is 1/2 inch farther back than on my 4.0. I still have my original driveshafts so I hauled them out of the garage and the 4.6 setup does have a shorter driveshaft in back and longer in front than the 4.0. I measured 1/2 inch which will be not problem for my aftermarket front driveshaft, but I will be using the 4.6's rear driveshaft.

The half inch is made possible by slightly more swept transfer case mounts. The bolt on portion. So I just need to swap those into my 4.0 and all will be good. The frame welded portion of the mounts is in the same position on both vehicles.

So I'm assuming I need to put my new transmission jack under the transmission when I un bolt the transfer case. Any tips on how or where to do that without chasing any damage?

 

To momentarily hijack my own thread does anyone have an opinion on a headlight swap? I like my glass rectangles. But are they as bright as the newer style headlights? I ordered a Mother's kit to restore the newer style lights but I could just sell them.

 

if you dont use the lights you can get $250-300 for them, are you just going to use your heads on the 4.6 short block? seem like the easiest solution

 

I could do that. I put new head gaskets in on the 4.0 two weeks ago so that would have been wasted effort but I can do that. Since I have everyt:hing togather and working on the donor I am tempted to just pull and transplant it all. SAI is new to me. All of my mechanical knowledge (what little there is) is from tinkering with my 2000/4.0. The SAI adds complication but is it worth it?

Is swapping the computers more complicated than grabbing all of the brain boxes in the passenger footwell?

I am having a BALL getting little plastic pieces, window seals, working door lock mechanisms, and updated instrument panel, a radio that doesn't have a break in the LCD (got a discount when I bought mine new in 2000 for that), extra side mirrors, and really perfect door and window gaskets.

 

i "believe" all the ecu have to be synced.
if you use the good block and your heads it a direct bolt in.
I saw set of Land rover gasket & Bolts for 89.00 on ebay.

 

Well I ordered mine for 127 (reinz) plus plenum gasket 17) plus bolts (44) yesterday on amazon so I'm an idiot. Ugh.
