Looks nice … please share the rest of the story. Was this DIY, or through a shop? Where’s the transplant from? Did you keep donor modules, LR4 modules, some mix? Run into the same issues as Hermes and Tapps33?

I want to know what happened to the front wing. On the highway at speed from your sc v8 must have been pretty loud ;)

@SCV8LR4 My main issues currently are the air suspension won't raise and comms as @Tapps33 said between ECU/TCM/transmission and consequently traction control. Would love to have my vehicle running. Did you swap all modules, flash just the ECU and/or add just coil suspension?

I think we all would love to hear how you did this!

Please don’t hate to break it to us!! That’s freaking awesome news!!!!

I’m just curious how you were able to get around all the communications and module issues? Granted I haven’t executed the swap yet as I’m still rebuilding my engine, (darn machine shop “2-4 month” turn around time. :mad:), but @Hermes is still fighting module and comms issues. I’m not one for reinventing the wheel, and since you’ve been successful, it would be awesome to know how you did it!!

PLEASE enlighten us all!!!

Hate to break it to you but I had a SC V8 engine running 560HP with velocity AP tune been running 2 years
You must be registered for see images attach
No sh*t, need to hear the process, I plan on pulling the engine and trans in a couple of years around 175k and doing the same. How much did the engine and labor cost you?

Hey all, sorry for the silence, like Tapps33, I underwent a move and have had no time. Furthermore the Rover is now hours away at my parents residence. Now I'm settled, I'm trying to get my build back so I can drive a Rover rather than a minivan!

Despite swapping out even the transmission mechatronics from the donor car, there still is errors between transmission, transfer case, ABS and suspension. I cannot get the suspension to raise, and even clearing faults compressor will kick in for a few seconds before throwing an error but even doing that over and over only the rear will raise. As the biggest reason I couldnt drive it to see if the errors would go away is I have new 275/55r20s on it and on bump stops they rub. So, I've been playing with the idea of swapping to coil overs to *maybe* fix errors and make it drivable (RRS had adaptive suspension, and I feel the module swap is causing issues with that hardware not being there despite disabling it on the CCF). Here's where I'd like input/advice: what coil overs should I get for this build? Options are normal coils or ones with 2in lift built in (I run rods currently, amd both sizes have the option of a heavy duty version with stiffer springs for towing etc.

Normal:

Lifted:

Heavy:

Considerations are,
• No lift means new tires. They are brand new and got them right before the engine died, with living in an area of snow I like beefier tires.
• Worried a lift will increase rollover risk dramatically, I could add spacers as I've run 2in spacers before long term no issue on my LR3. I also love the stance and probably add some anyway regardless.
• Regardless of height, would the heavy duty kit be better? Stiffer springs for more predictable ride? It is a supercharged after all, plus I've added weight with the SC engine up front.
• Note, I dont off-road or will I in this particular build. It is performance and looks based. I greatly appreciate the capabilities of Rovers and would love to make an overland rig one day, this just isn't it so lets not get into one of those argument threads (I've seen it before)

Thanks all!

Sorry for the late reply guys.
I did a lot of research prior to install.
The only thing I changed was the engine and PCM along with the aux radiator. I added the wiring for the supercharger pump and the boost pressure sensor that goes behind the supercharger. When you look at the wiring diagrams from the SC V8 and NA V8 there's not alot of difference.
I'm still running the NA transmission and it has adapted to the SC V8 Motor.
The PCM is plug and play once you have all your wiring figured out you just need to immobilize the SC V8 PCM to the LR4.
I've been working with Land Rover for 10 years now so it helps to have access to the workshop manual and diagnostic machines as you learn tricks on how to bypass certain security measures.
Overall was a good build and I love it. I want to get a 2016 LR4 and do a SVR tune conversion one day.
Thanks guys
Hope it helps
