Default 2000 Lincoln LS 3.9 to Jaguar S-type transplant

I have a blown motor on my 2000 S-type and am having troubles finding a decent price on a replacement motor. I have heard from a lot of people that the Lincoln LS 3.9 is almost the exact same motor and I can find these for a half the price. Does anyone have any experience with transplanting the Lincoln 3.9 into a S-type?

Sorry to hear about your problem.

It may (as in: might) fit - physically - but there are a lot more differences than some people think. Does the LS use the same (as in: the 100% identical) tranny? And PCM (engine controller, which btw is also the tranny one in that era car)? Or are you "just" going to transplant all of those as well?

And if you do, do the cars share ALL the other modules? (You know there are quite a few.)

Why not rebuild the blown engine? Get some good replacement parts and up the power a tad...

The basic answer is yes. The LS uses the same ford 555RN tranny. Same electronics etc.

There are a lot more similiarites than differences. Everything will bolt right up. You may have to mix and match accessories and sensors between the motors.

A guy on the X-type forum put a 3.0 duratec shortblock out of an LS- and all the accessories from the 2.5l into his X, and it runs fine and strong off the 2.5l PCM.

Would be an "interesting" challenge. (That's 5R55N, btw.)

You might need the LS's PCM as the 3.9 and 4.0 are clearly not identical. If you do need the LS PCM then you probably need its PATS-related items (ICM etc) or maybe a dealer could code round that.

I cannot remeber the member that rebuilt his 3.0 (it was a great write up with pics) but by the time he was done rebuilding the motor he had more money into it than a crate motor would have cost him.

Sorry... my brain wasn't working this morning, I guess. My eyes told it 3.0 not the 3.9/4.0

The main Difference between the two are the Intake manifolds and MAYBE some sensors. Oilpan to heads they are the same engine (Provided you get the SAME year).

The 3.9L (3934 cc) AJ30/AJ35 variant is a unique displacement used only by Ford and Lincoln and is built in Ford's Lima, OH engine plant. Bore is 86 mm (3.4 in) and stroke is 85 mm (3.3 in). The AJ35 version introduced for the 2003 model year added variable valve timing of the intake camshafts and electronic throttle control. While the block, crankshaft, pistons, and connecting rods are all unique to this displacement, many other parts are shared with the AJ-V8 engines produced in the UK by Jaguar.
Vehicles using this engine:
2000-2002 Lincoln LS, 252 hp (188 kW) 267 lbft (362 Nm)
2002 Ford Thunderbird, 252 hp (188 kW) 267 lbft (362 Nm)
2003-2006 Lincoln LS, 280 hp (209 kW) 286 lbft (388 Nm)
2003-2005 Ford Thunderbird, 280 hp (209 kW) 286 lbft (388 Nm)
Ford Forty-Nine concept
The last AJ35 was produced in March 2006 after only 3 years. Total run of AJ30/35 was nearly 250,000 units
When I had my 2000 I bought parts exclusively for a Lincoln LS when something broke engine related.

I would say conservatively that the Jag engine and the Lincoln engine are 97% identical.

One thing to note is the EXACT displacement of the engines.

Jaguar = 3934cc = 4.0L
Lincoln = 3934cc = 3.9L

Jaguar Rounded up. :P

You might want to get in touch with jagtechohio. At one time he had some 4.0 engines available. He can give you quotes and descriptions of what he has in stock as well as shipping info.

I am having the same issue, I plan on starting my project sometime this weekend. Hopefully the Lincoln 3.9 engine fits in my Jag 4.0, that'll save me a few bucks.

First the Wiki listed is wrong. The 3.9 and the 4.0 have identical bore and stroke. So the 3.9 L is not a unique displacement. It was done so people would not say that Jaguar is just a fancy Ford. But in the early 1999-2002 years it was really close.

Next you better check the VVT. The Lincoln engine did NOT have VVT until 2003 and it uses a different VVT setup than Jaguar. Now the LS guys have used the 4.0 Jaguar engine and disabled the VVT BUT you are going the other way.

To make it work properly you need to swap over the Jaguar heads and VVT gear. I think it can be done but details like this could make it a mess.

It's just hard trying to find a good decent motor around my area at a decent price. I found one with 140k miles on it for $2,400!!! That is just crazy for a engine with that many miles smh

I agree I am having the same issue. I cannot even find a crank kit to repair mine. I cannot pay 3400.00us for a motor that has 90k miles on it. this is very frustrating!!!
