I am sure soenone on the series 2 forum was making his own fuel injection set up for the 2.25, dont know how far he got, maybe wortth a search/join?
 
Iv seen the rover 220 engine into a 88 using the standard LR 4 speed series box.
Right off to you tube....
Found it. Attached next post

Inject the 2286.

Wiki has a mention of the t series, reckons it will fit lt77 and 380 boxes, and if it will fit them it will fit the series box.
 
As far as I know it is a points based system. Certain features being changed are worth a number of points. Once so many of these points have been reached, the vehicle no longer qualifies for tax exempt status.

From what I have read, the engine is only worth one point. There are a lot of Series vehicles out there fitted with more modern LR and some non LR diesels.

I'm no expert but I don't think it would retain MOT exempt status if you put a non Rover engine in it. When you go to tax a MOT exempt vehicle it asks if the car has been 'substantially modified' which a Shogun V6 probably is.

Reading into it on the HM Government website, it says if the engine has a different number of cylinders it is likely to be classed as a substantial change.

I wonder what happens in that case if you find a wreck of a six cylinder petrol Series missing its engine and start from there?

However there is also a line about "axles and running gear changed to improve environmental performance". I wonder if you could claim that you were changing over from the polluting diesel to a cleaner running petrol, thereby using their own rhetoric against them.

Unsure about the rules re tax exemption and modifications, but when I swapped my 2.5 petrol for a 3.5 in an early 90 there was no hassle with the licensing. Going from 4 cyl to 8 cyl didn't seem to matter plus the fact that LR made 90V8s, so it wasn't a substantial change.

A V8 into a Series could be classed as a substantial change as they never made Series V8s, though the Stage 1 V8s were 'Series'...not that it matters as I have seen loads of tax exempt Series with RV8s and others.

I'd keep it simple and go for a LR swap. 'Modern engins' have too many electronics to deal with.

From what I read, if the engine was an original manufacturer option such as a Rover V8 into a 90 it is not seen as a substantial change.

My thought about the 1990s era EFI engine was that they came before the electronics got too overly complicated. I believe that Mitsubishi and Toyota were building 4x4s with EFI petrol engines from the mid 1980s.

I said in the first post that I have no intention of actually doing it, it was only a thought I posted.

True, mine's 14CUX hotwire, very simple and does the trick.
I meant engines from more modern cars e.g 2000+.
I've never heard of a Mitsu or Toyota conversion in a Landy but I found this

Didn't read to check about efi.
Good luck :)

A bloke I used to work with told me he used to help out a mate of his to swap Nissan Patrol diesels into V8 Range Rovers.

According to him, at the time nobody wanted the V8 petrols as they were seen to be too expensive to run. There were apparently also a lot of rusted Nissan patrols with good diesel engines about so they went into the cheap Range Rovers.

To answer the original question; of course you can fit a modern EFI engine in a Series. Would it be worth the effort? I very much doubt it. Why?
Modern EFI engines are not sloggers, the torque curve will almost certainly not match the transmission
The fuel consumption gains will not be what you predict in the real world, dieselgate happened becuase they weren't even achievable in a modern car and there are now questions about petrol car data rigging too.
No way is a modern EFI engine more relaible than a Series. No never ever.
Does a Series have "limp mode"? No, so why add it?
You would need to drive 20,000 miles a year for 5 years to pay back what you spent. If you are planning on doing that kind of mileage do not buy a Series, the engine will be the last of your problems, start with the noise, seats, heater, brakes, steering, turning circle.....
So, yes, but no.

except the last defender pumas were only modified series
 
There was a regular stall at the Peterborough show with some reconditioned bare engines on display.

I noticed that the bare engines from the newer types looked very similar when stood next to the Series types.

As I remember, the TD5 block even looked similar to my eyes, obviously longer with one extra cylinder.
 
For me the killer is the pay back mileage required. I looked into an LPG conversion for a 5L Merc, you would think that would be a no-brainer, but it only does 1-2K miles per year and it was going to take 10 years to pay back plus the extra complexity and lower reliability as there was more to fail. This could be a lot of tricky work for very little gain. The std petrol is not a bad engine, they last 50 years and still have full spares support. Most moden ECU controlled engines become obsolete once the ECU supply dries up or the ECU cost exceedes the cost of a 2nd hand engine. If you can program ECUs this is not a show stopper, but I can't. Some people on here have built their own injection set ups (cast and machined bespoke manifolds) and programmed their own ECUs, that makes sense becuase its all under their control. But they have done that for speed - dragsters, race cars, not for a Series.
 
This is a thought I had recently due to the increasing anti-diesel sentiment by the authorities.
I’m a purist, give it a break FFS what totally stupid suggestion. Yeah let’s just ignore the provenance and revert to whatever blingy modification. I’m not aware of standard petrol series landys having emissions compliance issues.

Although it would not be popular with the purists, has anyone fitted a modern EFI Petrol engine into a Series?

As far as I know, it would still benefit from MOT, emissions and tax exemption while having a more reliable modern engine.

Some sort of Japanese petrol from the 1990s era would probably be a good choice as far as reliability concerns. This is also the era before the electronics became too over complicated.

I don't have the time, facilities, money or motivation to actually attempt this conversion myself, it was simply a "what-if" thought.
