And everything works

I bet it's a right hoot to drive, and a great tow car!!

Interesting that he went the route of keeping the original engine ECU with the bare minimum sensors needed to make it think it was running etc for the auto - I had considered that, but the diesel M57 power delivery just wouldn't have played nicely.

Nice work otherwise though, nice to see another engine swap that isn't a bunch of wires twist and taped all over the place or look like the engine was literally thrown in along with all the ancillaries from the original donor...

I see these days that the plate is on a BMW, so guessing the RR got sold.

Great work and looking down the Youtube comments someone else did the same engine swap earlier.

Couldn't help noticing the wire touching the exhaust at 3:28 though lol.

Well you could use Jag V8 ---- it's a ford engine & supercharged --- or you could always use real steel stroker kit that's 5 liter

Or just go to V8Developments and get one of their 5.4 litre motors, straight swap with no messing. Going for a different motor if you live in Oz, as the guy that did that does, and there's very little support for the LRV8 makes sense but not here. You're adding complication for the sake of it.

I personally think 5.4 must be at absolute limit ----- you forget ford V8 been raced and drag race even marine There's more tuning parts and cheaper than rover V8 ---- That's why stopped Rover V8 drag series ---- I wouldn't waste time with rover V8 for power as cost is crazy

Yep Symes I agree for the cost £7000 from V8dev for a bare block and 400hp it's amazing how much has to be done for such little power in the grand scheme of things.
Forced induction seems a worthwhile addition to the Rv8 to eek more torque out of it.

To be fair there is a chap on RR.net who has a stock 385hp LS motor in his, I bet that goes well.

Yep what interested me was how tidy the install was, like you say quite a few are just thrown together, his actually looks stock and everything worked!

Which is a rare for a DIY powertrain swap!

Exactly... you're spending big money on a Rover V8... £5100 if you want a 5.4 short, or 6450 for a long engine. Let's assume you go for a long engine...

That's nuts. I can't believe the standard ECU will fuel correctly to make big power - so you'd need to go aftermarket on the engine control, which will then force you into going Compushift for the gearbox, unless you're going dirty manual. So throw in another 2k or so in electronics - unless someone can tell me otherwise.

Engine swaps aren't anywhere near that money if you have the capabilities to make it work. And there are so many options that are better than a Rover V8. If you can make your replacement engine a) fit and b) run, the rest is possible. And you can choose anything you like within reason.

I seem to recall the Bosch thor injection systems limit power wise is 300hp after that you're in to aftermarket territory as you say..

The GM LS engine seems a worthy candidate for a swap, the 630R used one so it must fit in to the P38 bay AND it was paired to the stock HP24 with some slight addendums to the TCM mapping.

An easy 400hp and 521nm I believe that is with a particularly tame setup in the 630r

I wouldn't want to spend north of £10k on a Rv8 Build, just not worth it for the power or reliability "lack thereof"

Atleast for what I want to build mine for!

Hmm not really I'm adding complication for more power and torque..

Best bet cost to power /size is ford 302 it's smaller than rover but heavier BUT you can get serious power ---- Chevrolet not bad but weight can be--- depends which one used Craziest one I did was 455ci Buick in a Vauxhall Ventora That event rather well in a straight line

The LS is all Aluminum so weight should be no issue..

I just had a look at Chevy performance engines "long blocks" and for £7000 you can get a 525hp and 662nm.. Fantastic..

To be fair I think RV8 builders have a cheek charging 7k plus for "around 400hp" LOL

Of course you can also get the LS in smaller capacities for a much cheaper price.

I'm relatively sure the 630R used a GEMS ECU to run it - obviously with different mapping, and could then have been connected up to the older non-CAN HP24 controller, as you say also with custom mapping.

But anyway, lots of options for the custom route. Anything aftermarket under the bonnet can be seen as complicated compared to standard - because its different. You couldn't lift the bonnet of mine and then go to RAVE to work out why it won't start. You'd need RAVE and the BMW WDS to even start on it, before you get to any of my custom controllers. But I've built it, I know how it works, and as a one-off project, that's all that matters.

Plenty of support for Rover V8s in this part of the world, easy to get parts or find them in the wreckers. Indeed, as a young fellow I used to re-build them, and if you know what fits what, you can use a lot of Holden parts in your Rover (lifters, pistons etc.). However, Holden and Ford V8s are of course more plentiful.

this has been done before by someone in NSW , this maybe the same vehicle ?if so it has issues such as if you take off with gusto so to speak it will go into limp mode unless you wait for it to select second gear . also it involves alot of machine work to adapt the motor and transmission to mate up(theres a rightup on RRnet somewhere with pics)
just to note when Martin done his LS swap he quickly found out that the ZF trans was simply not up to the task of handling the LS motor, it exploded, which is why he put the 4l60e trans in it , also the engine mounts need to be rehashed as he basically ripped them from the frame on the rover which explains the cracks in the mounts . while its a good job and looks neat and tidy it dose have some little issues , but it is a prototype so to speak so its a good start .

For £5k could buy an L322 4.2 supercharged...

and? You have to remember the P38 is the last 'proper' Range Rover (and prettiest).

I'm probably wrong but I thought I remembered you once saying you'd love an L322?

The 5.4 RV8 is claimed to produce 'around 400bhp' but I'd have my doubts it makes as much power as the LS motor, a tuned Ford 5.0 or the supercharged Jag V8... Or would be as long lived as any of them? Easier to fit in a P38 because it would just drop in without any wiring or mechanical mods.

I can understand people preferring an older model car to a newer model and wanting better than newer model performance in the old one, said before I'd like an olde Granada mk2 and would like to drop a V8 in it and I'd prefer that over a mk3 old Granada with 2.9 Cosworth engine... But if someone likes both models and the newer model can be had complete / on the road with the high performance engine at cheaper cost than modifying an old one they could think might as well just buy the new one? Or buy the new one as an engine (and maybe gearbox etc) donor car for the old one could make sense if other high performance engines alone (just an engine not a complete running car with high performance engine) would cost similar or more. There's probably more 4.2SC's in the UK than 5.0 Windsors or 5.4 stroker RV8s.
