Default Interchangeability? AJ133 from Jag into LR4

No way to use the N/A engine in a S/C car the compression will be way too high, unless you swap the pistons out...

If you are having trouble finding a second hand engine, you could also use the 5.0L engine from an XKR, XFR (or XF-SC), F-Type V8S or R, Range Rover Sport or Range Rover Vogue.

Good luck.
My fellow members I am a new member on here and really need your help. I purchased a used 2010 Land Rover LR4 which has the AJ 133 5.0 V8
It originally had 79,000 miles on it and the first problem knocked at my door at 130,000 miles while on the freeway water pump blew navigate any warning lights no overheating gauge nothing in the motor cooked from overheating. I am in a big bind right now as this is our family vehicle with five kids my wife is driving me crazy land rover quoted me seven grand to do a head gasket but could not promise that the bottom of the engine is at 100%. I have done some research and found that the motor five point no GEN three is the same used in the Land Rover Range Rover and jaguar models non-supercharged. I have found one on a 2011 jaguar XF non supercharged, I am going to have to pay 3800+ a core and I don't want to make a mistake my question specifically is is it a direct fitment like some people say or how does the transmission connect given that my truck is a 4 x 4 and that this motor is coming from a 2 Wheel Dr. and there are other Jaguars that are all wheel drive? When looking at the connection where it actually mounts to the transmission it appears to be the same but I really need someone's help here? Please advise?

Welcome to the forum, sorry to hear about your troubles.

There are some minor differences between the LR and the Jag version, but they are just bolt-on things, the biggest differences are the sump and the oil pickup, you would have to swap the sump and oil pickup from your LR engine to the donor Jag one.

Reason being that the sump of the LR engine has the clearances for the front diff.

The exhaust manifolds I believe to be different between the LR and Jag versions.

The accessory drive is also different between the Jag & LR versions, but again this is just bolt-on stuff.

When you have the two engines side by side it's pretty obvious which items need changing, but the core of the engine, the block, heads intake and internals, is the same, just some bolt-on differences.

Have a look at this tech guide it explains the differences JLR-V8 AJ133 5.0 liter engine Components&ampSystems[1].pdf

Good day Sir! Was reading your thread and I am currently in the same situation as you were before. Just wanted to ask and follow up with your questions.. What have you ended up doing? Did you get the Jag engine from the XF? How was the fitment?
