- The first in our new series What Wednesdays, but it's not Wednesday - one of the most common questions we get asked is what it would cost to convert a diesel Defender to Rover V8 power. So, here is the answer.

It's nice to see a company be open about prices for once. Too many examples of websites saying POA or Contact us for more info lol
POA =expensive 😂
Excellent video on the likely costs of V8 conversion options, looking forward to the ‘cost effective power up’ edition! I can see my D2’s V8 4.0 going into a Defender when I find the right one, with a few RPI additions!😉
I could listen to him talk about these all day
I'm enjoying watching your videos, especially the Twin Turbo Tuesday but would like to ask, regarding fuel economy, is there much if any difference on a like for like engine between the Edelbrock carb and manifold setup compared to fuel injection?
For reference, here in Ireland I'm currently paying 1.25 euro / litre unleaded but the nearest LPG station is about 16 miles away and their price on LPG is 0.85 euro / litre which is considerably more expensive than when I was living in London.
(I'm taking a wild guess that red Defender is at least 30 years old if it's coming here, due to road tax differences: 1806 euro for post 1990 vs 56 euro for pre 1990! my RRC is 1989! ;-) )
We don't run these V8s for their fuel efficiency, but for the daily driver what setup considerations would you factor in for fuel efficiency?
it makes me want to weep when I heara Range Rover clanking along with a Perkins diesel. Do diesels do diesels get converted back To v 8??
Cool video
So around £22'000 for me to drop off a 4 cylinder or diese 110l, wait a few weeks and drive away in a carb 4.6 stage 3 😎
With another 2or 3k to fettle and add chrome giddies.
Yep thats pretty much the score. Obviously full spec and quote are to be done on an individual basis.
What radiator do I use for this conversion?
Would you convert a vehicle with a supplied rover v8 if it wasn't built by yourselves?
RPI quick question for you, if on 100% lpg do you still need cats if so what year?
In theory for the emissions test you do not, however we would advise that you check with your MOT tester or VOSA as a vehicle produced with CAT's should I believe still have them visible on the car as otherwise you are removing a emissions control device that the car was produced with.
What happens with the MOT emissions test if I swapped a Td5 for a V8?
Hi, I think I mention the answer to this in the video. But the basics are you need to find out form VOSA or your local MOT test station as to what emissions laws your vehicle would need to meet.
Hi do you do the ls3 corvette 6.3 and 6l80e transmission swap ?.
Hi,
Sorry it is mainly Rover V8 engines that we do.
We can import a new LS engines with the front end converted correctly to fit a Defender engine bay along with a new transmission pack. When I was last quoted for this a couple of years ago the cost by the time it was imported was around £35 to £40 thousand.
That 4.6 needs a fuel injection supercharger on lol that will up the power carbs are old school hard to keep fuelling right for rpm and load be looses of power though the vaccume effect ... injection is more effective/ efficient with power
Overall power through a carb or a EFI system setup and appropriated correctly for the engine would be the same. Granted EFi would be more efficient but at what % in a large 4x4 that has no aero dynamics then costs and customers requirements are always considered as well. We have produced loads of EFi engines for Land Rovers and other makes of cars power with Rover V8 engines however this carb setup is brilliant and is still correct for many of our customers needs and our own.
Would the 4.4 BMW V8 out of an L322 be an option to fit?
Any engine can be an option if you have the skills or know someone with them to make an adapter plate for the transmission or change the transmission, carry out the necessary wiring, potentially make custom exhaust manifolds, integrate the engine sensors with the dash etc etc.
I want the LS3 in mine I bet that’s going to cost a lot
The red defender looks as old as the other 2 but has a more modern front fascia, what is the story there?
As with many Land Rovers especially series, 90/110 and Defenders many parts are interchangeable so people change them to suit there style etc
the red one is newer then the other two ( see the area just below the windscreen aren't real flaps - ( flaps deleted in later versions) but its also before the Ford Puma engine ( 2.4 / 2.2) went in - as the bonnet isnt bulged as was required for the taller puma to fit
Over here I'd budget some money for LPG on top
any 3.5/3.9/4.6 in that body shell is a LOOOOOT of petrol
MMMmmmmm it break down and AA guy takes one look and says "wot????"
I built a 3.5 that I fitted in my series 1, 360 bhp at the wheels 0 to 60 mph in 3 seconds and 0 to 100 mph in 5 carb, no injection or turbo. You build a v8 right and it will give results. and it gave 20 to the gallon if you did not put pedal to the metal.
Wow 360bhp at the wheels is some serious power form a little naturally aspirated 3.5 engine especially with huge transmission loss. I think all our viewers would love to see that build!!!
@@RPIEngineering I Sold it a few years ago when I moved house I think I still have a few pictures I rebuilt the whole landrover from the chassis upI actually carried the chassis into my work shop and built it from the ground up. The engine was from an old tc shape v8 rover Stripped crank ground and balanced with lightened flywheel Arp studs in the btm a half race cam bleed down lifters Rover craft cyl heads stage 3 gasflowed adjustable moly pushrods to set preload ofenhouser inlet with holly vac secondery carb malory dual point ignition running electronic ig. original gear box but rebuilt the list goes on It took 3 months 9 to 5 to finnish.
@@julianthomson7398 I think you may have over estimated your power. 600 to 700 bhp at the crank would destroy a Series Land Rover gearbox. A 3.5 litre engine with stage 3 heads even with a decent cam would 220 to 270 bhp numbers at the crank shaft but would be rather racy and not suit most of our customers needs that want bottom end torque in a Land Rover.
@@RPIEngineering I took it to the dyno after building to tweek timing and carb and those are the figures they gave me.when finished.
@@julianthomson7398 Cool. Must have been crankshaft power though not wheel horse power. Rolling road (or chassis dynos as they are sometimes referred to) often calculate the power losses through the transmission and then give you the calculated crankshaft power.
Got a 07 supercharged range for sale anyone needs a good engine 78k miles lol
LS
Take a shit car and drop shittier car (Discovery) engine in it. Great option and only for 2K. ROFL.
Why would you bother total rubbish 3.5 v8 no power or torque never run right constantly miss fire over heating 10 mpg leaks oil noisy spend thousands of pounds for no benefit if your going to change the engine go Mazda 3.5 tdi diesel or just leave it tdi or td5 and before you ask I have had dozens of v8 defenders conversations and factory v8 total nonsense
I'm sure some would agree with you however many would disagree. That's what makes the world a wonderful place. Everyone has there own opinion of what makes a great Defender. For sure any old tired 3.5 litre engine is going to have poor efficiency and pulling power. Done right then can be great vehicles, most we see come through the doors here have been converted poorly and require corrective work and engine refreshing. But when you put the money into getting them right the V8 offers smooth refined power with great get up and go and a sound track that tickles most peoples interests as well.
