LS3 Conversion Diary

Hey RSmith,
I'm up in West Palm working on an 88 that sat for some years. Considered an LS swap for awhile but looking at your mounting costs, I can't justify doing it to a running car. I also own an 89 that caught fire and was supposed to be the swap candidate. It's future is still undecided. I'm down south on Friday and would love to swing by and check out your masterpiece if you're up for it

The Jag is at Texaco in Hallandale.
Address: 126 N Federal Hwy, Hallandale Beach, FL 33009
Mechanics name is Ronnie.
If you are there Friday afternoon or Saturday, I can come over and meet you there. But feel free to stop by anytime without me.
BTW, does anyone know why I can edit this post but cannot edit some of my earlier posts?

Since I have to reprogram the trip computer on my car after the conversion anyway, I figured why not update to the newer version. It simply looks far better.
I had a few questions though...
Has anyone done a trip computer retrofit? Will it fit the same harness? Is it even possible?
Also, since it is smaller and more centered in the space, is there a different bracket behind it that I will need?

From there it can calculate distance and fuel used.
As far as I can see from the JDHT site speed sensing is the same for all late cars with the diff mounted speed sensor. I could only find the diff rear cover and its the same part number for late prefacelift all the way to the 6.0L.
So going by this the late trip computer should be plug and play with any XJS with DIFF mounted speed sensor. Plugs MAY be different but that would only mean changing the connectors.

Back to our regularly scheduled programming...
The welder was in today. He is custom cutting some additional supports for my left front subframe to be safe. They will go in tomorrow.
He also modified the oil pan for me. Despite the $300 oil pan being a close fit, it still will not go in without modification. No choice really though. If you want an LS3, there are simply no stock oil pans you can use. There goes another $200 for that mod though.
On the upside, Andrew provided extremely detailed instructions on what to do. There was a full page of instructions with drawings and measurements. If I knew how to weld I could have done it myself with those instructions.
I will post some pictures of the new supports after they are welded in tomorrow.
Running total $13,142.

Just out of curiosity, what mods needed to be done to the oil pan? Is this the F car oil pan you're using?
Too late now but...as an aside and maybe future reference, there are several aftermarket LS oil pans available specifically for LS swaps. These pans offer more clearance forward of the sump.
The ones I'm thinking of are cast pans, just like the originals - not fabricated sheet metal jobs. Holley makes one, GM Performance parts offers one and there may be others.
Maybe one of those would work in this situation?

Thank for that though, and good future reference for others considering the swap.

By the way, as part of this project I am re-dying my seats. Since they will already be out of the car, and lumbar/heated seat buttons are so cheap on ebay, I was wondering if that functionality could be retrofitted.
I would be using these parts:
Lumbar Support
Heated Seats
Is that possible?

This is a V8 thread so no spamming here. If you don't like the V8 threads then don't read them. Are you reading the V8 threads just to complain about them? If so STOP
#38
V8 spam refers to the tw@ named SirReginald spamming all V12 threads with 'do a V8 conversion'. Jez, I would have thought people can read...
But flag me I don't like V8s... As rsmithline asked a question to SirReginald and as SR can't answer due to spamming OTHER threads regarding V12 issues with stupid replies regarding V8 conversions, I am now a V8 hater? Or a Vhater? Haha... Sorry...

Comments on LS Oil Pans
I just wanted to pass along some notes on the LS-Jag oil pan discussion here. When we first did the R&D work for the Jag-LS conversion we tried nearly every pan that was out there for fit. Remember, this was back in 2008 and there were no aftermarket pans that weren't fabricated steel (welded, and required a remote oil filter mount), etc.,. This is before even the GM muscle car pan kit was released (which is actually the Hummer Alpha pan and hangs way too low for us anyway). Back then we settled on a particular GM-based pan and made the modest mods necessary to it to work in the Jag chassis. The main objective of going this way was to maximize ground clearance- this pan, used with our LS mounts, does not hang any lower than the front crossmember or the transmission bellhousing. Now, 8 years later, some other options to consider are available. We have not tried the Holley pan but I have one customer who was going to give it a go- we have not heard back from him on that. The Holley pan is actually almost 1" llower than the pan we use so in our applications, the sump would be the lowest point under the car, something a Jag owner would have to decide is ok or not. The Mast pan is similar to the Holley pan but also lower in back than our preferred unit (by about 3/4") so it would also be the lowest point on the car. From a profile standpoint it looks (although it is not confirmed) like either of these will fit our chassis with the ground clearance thing my only concern.
For those doing our conversion now I will respectfully ask that we keep the details of exactly which GM pan our kit recommends for the Jag application, and the required mods, confidential. Those details are for customers only-please don't share that info with anyone.
I am really happy with the back/forth discussion going on here- it's informative and open- just enthusiasts sharing experiences, tips, etc.,. Good for the process.
Thanks
