Rover P4 diesel conversion

[Pete-M]

A diesel P4? That is wrong on practically every level since levels were invented (1982?)

 

About the only plus for this bloody awful idea is that they didn't ruin a six pot P4 to do it.

 

Fucking awful idea, and may a particularly nasty pox be upon those who have been irresponsible enough to act upon it.

[Richard]

I knew you would be pleased.

[freebird]

I thought the word "fucking" was frowned upon?

Somebody been fucking lying to me?

[trigger]

You are doing it wrong!

a 200tdi does about 28-30 mpg on dizzle at 141 per litre

 

a 4 cylinder p4 does 28-30 mpg on petrol at 136 per litre

 

a 6 cylinder p4 (2300 not 2600) can do up to 25 mpg on petrol

 

it wont be much more economical

 

I very much doubt if a 2.25 P4 would do 30 mpg if you pushed it over a cliff. Wether or not you get 30 mpg out of the dizzler is not really important, I bet it'll be capable of reasonably brisk progress, which the P4 with a 2.25 certainly wouldn't be. A P4 Rover 100 /110 would struggle to get 20 mpg in any situation.

 

not talking 2.25 p4, I own a '60' model p4, 1997cc's and the missus was commuting 300 miles a week in it

 

ive got a 2.3 1959 '75' in my posession and its doing 25mpg and thats a non overdrive

 

my minge rover 200tdi does about 30ish mpg

 

runing on cherry and chip fat though could be economical and the tdi will weigh a lot less than the original lump

 

my point is, youve got to do a lot of miles to recoup your outlay

[scruff]

would a TD5 fit in a P5?

I have always liked the look of them and the idea of driving round pretending to be Harold Wilson is appealing.

and what if one could get an auto box with that TD5?

 

I'm sure it's possible, you could hook up a car version of a ZF 4 speed to a Td5 auto bellhousing. I'd imagine it would not be a simple swap though. The joy of the Tdi in the 4-banger P4 is that is bolts straight onto the gearbox and sits on the existing engine mounts. My mate said a lump hammer was needed for wing clearance and the oil filter housing is touching the steering box, hopefully a housing from a 2.5 Landy petrol will fix this. If it was a nice Rover and not a total shitter you'd have a fair bit of fabrication to get it nice and tidy I think.

 

Glad it gets the Pete M seal of smoky disgust

Breaking the Disco the engine came from, and selling the 2.25 petrol lump, has made him break even.

 

You are slightly missing the point though, it isn't supposed to be sensible, he only did it because he could and it's a bit funny

[Pete-M]

It's a diesel engine where a petrol one should be, so of course it gets the PMSOSD.

 

It's especially galling as the P4 (sixpot, natch) I had sat in a shed for 20 years, untouched, and to get it going all I had to do was connect up a fresh battery, whang some fresh petrol in the carb and turn the key. Rattled a bit at first (perhaps I should have changed the oil), but it was a nice old lump. Replacing it with a 200 TDi would have been very, very wrong.

 

Mustard mitt, if the thing isn't actually running, the sight of a turbo under the bonnet of a P4 would cause a moment of mirth. Just a shame it has to be attached to Dr. Diesels Evil Invention.

Surely a 'modern' diesel in the place of a low revving , old fashioned agricultural petrol engine isn't that offensive.

[Pete-M]

As I said, it's less offensive than if they'd hoiked out an IoE 2.6 to do it. The 2.25 isn't wonderful in any way, but at least it runs on the correct fuel!

[Albert Ross]

Knowing the perpetrator of this deed, reasonably well, this does NOT surprise me one bit. I recall mentioning something like it 2 years ago over cider.

I wonder if a Santana 6 would go in..... 3429cc petrol or NA diesel... same bellhousing too....

In particularly cold weather the owner might have to mix petrol with biodiesel to stop it gelling, thus running partially on 'correct fuel'.

Interesting, are they a development of the Rover 4 pots?

[scruff]

He's had Drew's boss on the lookout for one for the past two years Albert

[ashmicro]

BAH! KV6 it, the K is the world's finest engine as any FULE know.

 

Actually, an AJ6 ought to go in there too. FWIW, I think it's a decent idea. Not the execution, just the idea. Mind you, not my car and all that, and Rover genes.

If an AJ6 will go in, that means that an AJ16 will also go in.... which means the XJR lump would probably fit. That'd be more fun than a 200 TDi.

[Albert Ross]

Yup, basically 3/2nds of a 2286, using the same rods and pistons, valves pushrods etc. So an OHV 6 instead of the more fragile IOEV, with parts interchangeability with the 4 pots. I am seriously thinking about a trip to Spain in a hired van, to try and find a petrol and a diesel engine, each with a gearbox. I SO want them.

Agreed, Lord Murray. Stopping it, however, would be EVEN more fun. Here's a twist - a local mentalist here, some years ago fitted a 3528 Rover on carbs in an XJ40, just to prove it could be done. He and his brother did it in a day, with the rest of us neighbours bringing them tea/beer/ sarnies and wondering why. Worked, though.

Old car + efficient and modern-ish turbo diesel = SUCCESS.

 

I'd love to do something similar. Volvo Amazon + VW D24TIC out of a 940.

 

I think that's the most offensive thing you've ever said on here.

 

The B18 in my Amazon is only crap because it's shagged from neglect on the part of the last owner. Properly set up B18 \ B20s are fantastic things, so long as you forego fuel economy. I suppose intended use has to be a consideration too in all of this. I can *sort of* see the logic in using a diesel engine in an Amazon if you were doing an every day commute in it. I ended up spending over £200 in fuel when I ran the Volvo as a fake DD over a two week period, and this was my every day routine. No stupid collection trips South, just the daily grind up the M56 to the then current job, some trips to the unit and a couple of trips North to Preston to see some friends. I don't know what a correctly set up 120 is supposed to achieve. My car is running the worst carb on a non overdrive box, and what's more, the engine is breathing heavily. In town I was seeing 15-18 mpg, and about 21-22 when on the motorway. Whilst being deafened by the engine screaming its tits off at 4900 RPM in top. A daring 6000 RPM blast tore the snot out of my nose and gave us an indicated 100 mph (89 on the sat nav).

 

So on the basis of a working vehicle, I can just about see the logic, even with the traditional cost advantage of diesel itself being wiped out. I'm not as opposed to derv as Pete - my last and current cars ran \ run on the heavy oil. I can also see the benefits if it means a shagged car is brought back to life and run 'as found', upsetting the purists whose cars see at best a 100 mile commute to the cum and show brigade.

 

Several Amazons have been converted over to the black death. A VOC member runs a 222S on a 1.9 PD VAG engine, and there's a clone of my car with a Perkins Prima in it. The latter is used as a toy, much like my car. Why you'd want a pleasure vehicle to sound like a decrepit cross channel ferry is beyond me, because every logical reason for ripping out the B18 has been removed.

 

Yeah. The idea doesn't do it for me at the moment. Perhaps when the weather's nicer.

[Inspector Morose]

I know it's been done many times before but my ideal car would be an early series one v8 rover P6 with the turbo xud lump in it.

[Guest Leonard Hatred]

I only know of one, eggy's P6 XUD7 TD, but I think it was converted from a 4 cylinder P6.

I'm a fan of the Kit car way of powering a car.....you know.....a Lambo replica with a B Series ratling away under the bonnet!

 

If I EVA win the lottery then I will amuse myself by buying new cars - and retrofying them....

 

so a Q4 with a perkins dizzer

 

A 5 series BMW with a fiat 1.4

 

A new Disco with a Douvrain

 

and the piece de resistance......an S3 with a 1098cc A series....

[scooters]

oh - ad I forgot the XC90 with a B18!

[Guest Leonard Hatred]

Audi R8 with a DKW 2 stroke 3 cylinder engine for mikey.

[Guest]

That wouldn't be able to move! Or is that the idea?

 

Clever, if it is.

[AnthonyG]

A mate of mind has put a Perkins engine into his P4. The Perkins lump was out of a Commer walk-through van, I will have to ask him what the capacity is. He was talking of selling it for £750, if you're interested DW - Its in Lampeter.

 

He's also put a 200 tdi into a SWB series 2 and loves it, plenty of power. Next to do is put parabolic springs on it so it can go round corners!

[mattblack]

A chap at a place I used to work had a perkins powered FE Victor, nicknamed the Green Goddess. He replaced it with an ex-taxi MK2 cav dizzler.

Hmmm. I fear I may need to know more. Sounds delightfully miserable!

[AnthonyG]

I'll ask him at the weekend - he changes his mind constantly about taking the Perkins out and putting it in a LR Station Wagon, or just leaving it in the car and selling as is. I 'think' it has a current Mot. I'll PM you with details DW if I get any info.

Don't forget: when trying to flog such creations on eBay, simply state what has been done but offer no explanation why. Then don't respond to questions.

Cool. I'd better hope the bloke flogging the 2CV resto project doesn't get back to me then...
