OK, so I don't actually own a S-Type. But I do have the engine.
I'm swapping the engine into my 2003 Miata. Some of you may have heard of the kit. It's the Rocketeer Kit. I was able to purchase it second hand from someone that had to bail on the project before he even started it. I got both kit and a 27k mile engine from him. Engine is from a 2000.

Unfortunately that engine had been in storage for 14 years. And because of that reason alone I wanted to replace any and every seal. Which meant pulling the heads. That's when I found some corrosion in #1 cylinder. Not a lot. But enough to warrant bore and hone. Which means new pistons and rings. That's gonna be about $650.00.

So I went on a search for a good block. Not a lot of those out there. And 2 of the yards I've contacted haven't returned my email. (car-part) So that's frustrating.

I found another engine locally that had "light top engine fire" for super cheap. Unfortunately that one also had a cylinder that was very corroded. So I returned that.

There is a 2003 Lincoln LS engine very close to me. 111k miles. Looks very clean at first glance. All I need is the block. Or in the case of a whole engine I would use the short block. But is it compatible? I can't seem to figure out a way to confirm this. Head gaskets are the same. But timing sets have different part numbers. This is the case even when I search for timing sets of the same model year for a Jag vs. a Lincoln. The Jag shares compatible timing sets with other Ford duratech engines. But the Lincoln always comes up on it's own when I search for a timing set. Which is very weird to me. Why would Ford do that?

So I decided to look at casting numbers for the blocks. Both Jag engines had the same casting number. RF-XW4E-6015-BA. One was a late 2001, the other was a 2000. Interestingly the location of that number on the block was in a different location on the block. But the LS engine casting # is RF-3W4E-6015-BA. That one is a 2003. Does anyone know if the different casting number would make a difference for me? Can I use a 2003 Lincoln short block with everything else from my 27k mile jag engine? Does anyone have a link to a reference of casting numbers and how to decode them? I can't find anything for these engines. Yes, I've done a lot searching. I'm thinking of contacting Ford. Maybe they could help.

Any help would be greatly appreciated. This particular LS engine is very close to me and is only $270.00. Then I could sell a bunch of good engine parts to re coupe all of my $.

 

Wow, that sounds like a fascinating project. Have you contacted the manufacturer of the conversion kit? As they are based in the UK, they likely chose the Jaguar engine as this is not a super rare donor. But I can't imagine there are too many Lincolns in the UK.

They may know if the Lincoln block is compatible. They probably haven't bothered posting this info as the conversion still requires Jaguar heads. You're in a one-off situation of already having good Jaguar heads but need a good block, whatever source that may be.

 

Yep, I'm in touch then. In fact I was ready to buy the LS engine and he is the one that suggested I do my homework first to be sure it was compatible. The only thing keeping me from using the LS as a whole engine is the VVT vs CVVT. The ecu included with the kit is programmed for one or the other and is ordered based on which engine is chosen. That and the connectors are different. Otherwise it is all the same.

 

Just thinking out loud now, so you've been warned...

The potential differences may be as simple as external mounting points for components such as the water pump, alternator, etc. The basic casting may be the same, with mounting bosses for all configurations. But only the appropriate bosses are drilled and tapped, depending on the application.

It may be tough to get a definitive answer. Wish I had better info for you. Perhaps you could compare aftermarket part numbers for the external components. That might give you some idea.

 

This link for a V6 Lincoln motor put in a V6 X type and states the block is the same in post 3. There is a post further down talking about the water pump bolts not lining up.

This link (below) shows the work involved and the different parts between the 2 motors with photos. If you are only using the block then it looks like what you are wanting will work. The link is from 2010 but it might be worth contacting the forum poster.

I have no experience with this sort of swap so I am only going on the links from the X Type forum and thought they would be useful to you.

Uff da! I may have offered some bum advice about comparing aftermarket components. I forgot all about my experience with incorrect part numbers for the water pump for my '02 V6:

https://www.jaguarforums.com/forum/s...3-0-v6-204901/

 

Well the kit uses an electric water pump and not the factory unit. But still mounts in the same general location. Thanks for the links. I'll read up. And it gives me another direction to look into things.

 

Those links give me encouragement for sure. The one thing that still makes me hesitate is that there is a VIN # break from my 2000 to the Lincoln's 2003 which means the timing gear is different. It went from a VVT to A CVVT system. However I haven't come across anything to suggest one way or the other that there was a change in the block.

I'd really like to see what the casting numbers mean. Why are they one digit different? What does that one digit mean?

I sent an email to Ford. Hopefully that will lead somewhere.

I'm almost tempted to go for it anyway. And if it doesn't work, I could part out the engine and get my $ back. Which is a bit of a gamble. Might be hard to sell those parts. IDK.

 

The swap thread in the X-Type forum was referring to the differences between the mounting of the engines. The X-Type has the engine transverse, the LS & the S-Type are longitudinally mounted. There's a post from Count Iblis around here where he mentioned that all V6 blocks were produced in Michigan and then shipped to the UK for Jaguar to put their own heads on. Lincoln made their heads here. Supposed to be the same, but the UK heads were supposed to be cast better. The bottom ends are the same. If all you need is a block you can use any Duratec 3.0L V6 bottom end, but you'll have to swap the front covers, accessories & wiring, and reuse your original heads.

 

Oh yeah, the X-Type has the water pump mounted on the camshaft at the back of the engine so you're gonna want the LS or S-Type heads for this swap

 

Swapping the jag heads onto the LS block is exactly what I want to do.
But why are the casting numbers different? 2000 jag engine vs a 2003 Lincoln.

Where did learn that all blocks were cast in Michigan?

 

Check out here and here. Maybe it'll help

 

Ford's Cleveland Engine Plant #2 is the source. The original window sticker of my S-type actually states that origin of the engine is the U.S. and the transmission (in this case) is from Germany.

 

Cleveland! That was it! Thanks S-Type Owner. Not sure why I was thinking Michigan

 

Also here

 

Oh yeah, the 2000 block was 1st Gen, the 2003 is 2nd Gen. Both Jaguar & Lincoln issued new part numbers for a lot of the parts for their vehicles whenever they gave them a facelift. Some stuff changed, some stuff didn't. The online catalogs sometimes have superseded part numbers that can help, but there's still some things that crossover that you'd never think of. Check out the "Confirmed Cross Referenced Parts" threads in the X-Type & S-Type forums. Should come in handy

 

Well, with all the questions and research and help from every one who posted here, it was all for nothing. I was able to confirm by about 99.9% that I could swap blocks. I called the junk yard to tell them I wanted to buy the Lincoln engine only to find out they sold it. They had it for 8 years.

Oh well. I found a 79k mile 2001 jag engine 2 hours away and it's only been sitting for under 2 years. More $. But thats OK as long it's a good engine.

Thanks for everyone's help. It's greatly appreciated.

 

You can remove the water pump drive splined adapter from the back of the camshaft, and put in an aluminum 1/2 plug where it passes through the back of the head and put on an S-type valve cover.
The camshafts are the same. No need to swap heads.

Who'd have thunk, but hope this new engine works out well for you.

Even if you don't need our help, as it sounds like the conversion kit has all the details covered, please check in occasionally with updates. Pics, too, please. This sounds like a fascinating project and I'd love to see how it progresses. We don't see much in the way of engine swaps around here. I'm very impressed with the V6 in my '02, and imagine the performance would be absolutely amazing in a light car. Giving myself goosebumps here.

Do I understand correctly that the conversion is basically using the Jaguar metal but with a control system that's a mix of Mazda electronics? That should make the electronic side of the integration much easier.

And then of course, what do you call such a converted car? Is it a Mazduar? Or just Mazuar? Or the other way around: Jagzda? I kinda like that last one...

 

Will do on posting some updates and pictures. Got the old, 1st engine torn down so I can hopefully sell some parts. They only have 27k miles on them. And I won't be looking for top dollar.
Pucked up the new one yesterday and peeking inside the oil fill it's amazingly clean. No varnish what so ever. Even cleaner than the 27k mile one. It's on the stand now. I'll start on it shortly. Just taking a break right now. I'll still replace all seals and thoroughly go through it. Gonna be pissed if there's problems with this one.

As for names, I've seen MXV6, and Jazda. Actually if you search YouTube for Jazda he has a quite a few videos posted.
