I started looking for a 5.0 V8 Sc engine everywhere in Panama and it was impossible to get it. Only in the United States did I get it, but it was very expensive for me. Only the shipment came out for $4,000. I continued searching here in Panama and got a 4.2 V8 superchargerd 2008 engine. I decided to buy it and try with a mechanic friend. We have already assembled it and I am bringing pulleys, hoses, tensioners, wiring new accessories from the United States.

I would like to know your opinion and recommendations. Do you think it's possible?

 

Very interesting topic. I'm eager to see if you can do it, as I live in Mexico and have similar issues to you in terms of getting parts etc. We all know that the 4.2 engine is considerably more reliable than the early 5.0s, and I often see 5.0 models for sale extremely cheaply as they've jumped timing and nobody here knows how to fix them properly.

My instinct is that it won't be possible as the various different electronic modules of the car won't work properly together. I'd love it if you could prove me wrong though. I currently have a 4.2 model, but I would love to get a broken 5.0 for my wife and put a 4.2 in there if I could.

 

Hola amigo! Gracias tu respuesta. Estamos Confiando en Dios que funcione. Estamos esperando llegue el ramal de cableado del motor 4.2. Apenas llegue sabremos y enseguida te pondré al tanto.

 

I’m just interested in seeing if it can be accomplished. Backwards compatibility is often more challenging than forward. Not to say that updating to newer is without its challenges.

Even transplants from other makes or models is difficult.

Gracias por escribir amigo! Aquí estamos trabajando. Apenas tenga la definitiva sea buena o mala noticia estaré compartiendo por este medio.

 

I have a feeling the ECU(s) are going to have to be heavily modified to work. Quite a few changes from 05-09 to 10-13. May want a GAP tool and contact them or Bell auto in the UK to have the code rewritten/see if it’s even possible.

 

Hello friend! Thank you for commenting. Yes, that's exactly what my mechanical friend told me. He will work on the ECU configuration. I would like you to explain to me a little better about what you tell me about rewriting the code. I am entering this Range rover world again and I would like to learn more. I'm really a kkkkkkk violinist. I know you have a VIN number and through it you can identify the types of engines. The D is Natural aspiration, the E is superchargerd. Is it the VIN you mean?

 

A noble intent to “save” this vehicle.

However, by the time you’ve made the necessary modifications to ensure a reliable outcome to include:

a) replacing the entire original wiring harnesses (both under the hood and the body harness) with the “older” set-up as used by the 4.2 and 4.4 motors along with the [existing] completely non-compatible BCU and ECM for the earlier L322 MY2007-2009 platform.

b) modifying the fuel delivery system to swap from the high pressure fuel injected original motor’s set up to the earlier much lower fuel pressure system (probably the easiest part if you’re resourceful).

…it would’ve been less expensive and less time consuming to source a Jaguar based 5.0Sc motor and simply modify that by switching out the oil pan and pickup, front pulleys and some other very minor adjustments and installing that.

Jaguar engine availability is far greater as they were sold in higher numbers than their Range Rover cousins.

Finally, the later model security is based on the CJB. Once you’ve swapped over to the earlier BCU and ECM type set-up for the Jag 4.2 and 4.4 motors you’ll need a completely different set of keys (fobs) made for that BCU immobiliser network.

Best of luck,

Rob

I agree with you with regards to the complexity of this project, and I'm also not sure it will work. However, it's important to remember that it would be just as hard, if not harder, to source a Jaguar engine in Panama than it would a Range Rover one. To give you an example, I used to own an X350 version Jaguar XJ here in Mexico, and in the 5 years that I've lived here, I only saw 2 others. I've seen perhaps 3 L322s apart from my one since I got it. To be honest, I'm surprised he even managed to find a 4.2 motor, let alone a 5.0 one.
