Hey everyone. I couldn't find a thread on this yet for the S-type. I'm looking to get a GTO 7.0L LS motor and manual trans. I'm wondering if anyone has done a complete LS swap in an S-type yet or even a manual trans swap for our cars? I have also seen bolt in kits for the XJ8 does anyone makes a kit for this yet? Or even motor mounts and trans mounts?

I'm doing the research now. My plan is to run my motor till something catastrophic happens then have the LS ready to go. I'm all for Jag in a Jag but lets face it if your going to have to replace a motor or a trans on this car cost wise it seems practical to do a motor swap for longevity and fun.

 

Well, there is one MAJOR flaw with your plans..... The 7.0 is a GM motor and nothing in your modern S Type will want to work with it.
BTW, an active member here is working on something very similar. His is an LS3 swap.

After reading through the pages of this thread, you will understand how monumental a task it is.

Your reference to "early" XJ lumps (with 350 Chevy's dropped in) are really no relation to modern Jags.

1) The electrical was way easier. No messy computer modules to worry about. Just need a blueprint/diagram.

2) GM was the supplier of transmissions to Jaguar for many years. Now you know why all those conversions were GM V8's and not Ford or Chrysler.

And before you start thinking you could throw in a Ford V8.... Nope.... The V8's common in trucks, Mustangs, and other Ford cars are of no relation to the Jaguar stuff. Actually, it was Fords that ran Jaguar stuff. The Lincoln LS and Thunderbird both had the 3.9L version of the Jaguar AJ V8.

Sorry to burst your bubble...

 

Second problem. The 7.0 Liter never came in the GTO?? First ones had the 5.7L and the last ones had the 6.0 L.

If you use the 6.0L it has 400 HP. About the same as the STR. Just get an STR it will be better all around!!

Nice catch... I usually pick up on those things...

The 7L LS7 is a Z06 Vette engine. It will also be in the new '14 Camaro Z28.

Yes on the STR sentiment. Even @Tijoe has one now. The 2000 has become a side project... A cool one, but years on, still not done.

 

besides, the 7L LS7 only produces 500hp, well 505hp to be precise, with the time, money and effort involved it's just not wort it, you could buy a mint str and mod it to close to the hp of the 7L for a lot less effort

 

I Have An STR With A Damaged Roof, I Might Sell The Parts From It. It Has Four Brand New Wheels If Anyone Is Looking For The Staggered Wheels.

 

let me know I need some interior parts things off of it. I might consider the motor, trans, both wire harnesses, ecm, tcm.

 

Would you post pics of the wheels?

 

Candys Kitty And Blakkat..

I'm Getting My "Parts" Car Back From The Shop Today. I Will Post Pics After.

 

are you going to try an engine and box swap ?

 

I may be interested in the wheels, I have a bent rim. Pics please and $$

 

How did you damage the roof on your car?

Someone was looking for moonroof parts as they had broken some parts on theirs. Hopefully they will see this thread.

Took My Baby In For A Fluid Change And They Didn't Latch The Hood..And Drove Way To Fast..

All Wheels Same Condition Zero Curb Rash. Unsure Of Price As Of Now..Open To Offers. Will Take More Pics If Needed.

 

I think you held your temper very well!!

I sure hope you get top money because that blue STR in not common!

I'll be honest, I settled for the silver car because it was nicer as far as condition. I've looked all over and have only been able to locate one other blue STR in the States. Ugh Lol

 

100% considering it. I'm in the research phase. It seems as though I can get the LS1/2 with a manual transmission harness and ECU easily. I would need to get a shifter and pedal box from a manual S-type, have motor and trans mounts made as well as a driveshaft. Then I just need to figure out how I will run my creature comforts. AC, Power steering, etc. I also need to figure out if I can make the original gage cluster work or make my own. The other possible option might just be to find a manual trans to run on the 4.2L and just switch to a stand alone system. If I did that I would want to do some engine work and possibly lean toward some sort of forced induction system.

The benefits that I see with the LS so far is the size and weight of the motor. It is more reliable power in my opinion. Also, I believe the LS has a more upright cylinder bank than the 4.2 and would create more space in the engine compartment for say supper chargers or turbos.

Like I said though. In the research phase.

 

I'm interested in the side skirts, head lights, and if you have the plastic piece on the dash between the windshield and it is still in good condition.

 

I'm also thinking I might want the window trim, and possibly the front bumper and grill. I was going to do a 2009 front clip conversion but the 03' STR bumper is growing on me.

 

Wow, a fluid change totaled your car. I don't know what I would do. What did you say to them.

 

I reckon you won't be able to keep the gauges - well, not the module etc that drives them - or any other modules. They all use non-GM bus networks and message packets. Various are part of security/immo, too.
