Putting diesel engines in V8 cars

[Akzle]

if any have done it what did you do?

well... Took the petrol engine out and put a diesel one in.


Diesel fumes are carcinogenic.

Megasquirt it if its not injected.

you got one in nz?

Giz it

My favourite engine is the turbo diesel. However up to my size car, the Suzuki Kizashi, which is a 2.4lt petrol four, it was cheaper to buy and run petrol. I am just doing 25,000km p.a. but I get under 7.6lt/100km on a trip and 8.9 around town. It is criminal that small diesel vehicles are rendered invalid by the RUC's!

As has been pointed out, you will probably want to up the gearing as well, but a modern turbo diesel will do about the same revs as the old V8's.

25 k would be enough to break even i reckon,My 2.0 diesel does 6.5l per 100k round town and 5.5 or better on the open road.I suspect it would be more than a match for your 2.4 in most real world situations.RUc is 5c a kilometre the extra rego is about 200 bucks.If i can be bothered i will stick your figures into the spreadsheet i made up once to figure out my actual running costs

Yeah, I worked it out that the Kizashi was the limit I could go to match diesels. It is more economical than the others in the class and that made the difference. It was also significantly cheaper to buy. Any larger and much more mileage and the diesel would win. Shame, as the modern turbo-diesels are fabulous engines! Much more torque as you well know.

Diesels mostly rev lower than petrol engines, so you'd probably need to consider a gear box and of diff as well.

Yup thats when the money starts to flow and that cheap engine isn´t so cheap anymore - gearbox to diff ratio matching, propshaft length, clutch actuation, temperature sensors, speedo, tacho, fuel return lines, pumps, swirl pots, ECU harnesses, exhaust pipe routing, throttle linkage, radiator hose layouts, ignition switch wiring, extra relays/fuses, engine mounts, gearbox mounts/crossmember placement, sump clearance, bonnet clearance, gearlever placement.....

Interesting comments fellas.

and it just perked my interest for a fleeting moment. Remember the cool vans from the 70s?
Anyway the odyssey which is my work car is too low for most of the driveways I go into around Nelson. It is always bottoming out & although it is comfortable to drive it is sometimes a pain to work out of.
I don't like modern Jap vans-like their bikes they have no character (apart from the mighty KLR of course) so I started looking at alternative work vehicles.
I love old Broncos & yank vans however they all seem to come with 6L v8s. I would shudder to think what I'd pay for gas running one of those beauties around all day. Anyway since diesels are so prevalent on the road I thought maybe there would have been a few that have done the conversion or gone thru the logistics.

So the more modern V8s are not too bad on gas? I think I'm getting 450kms out of 55L of gas in the odyssey - it is carrying a bit of gear in there.
Those lexus V8s are apparently cheap to put in to cars from what a young mech told me but he may be talking crap.

Ohhhh cool

Its worth looking at improving MPG on a gas guzzler -any improvement makes a big difference when your below 30MPG - above 30 - not so much bit of a diminishing return so that petrol option might not be so bad after all:

Guy I know put a 6.3L diesel in a mid nineties Transit, said it would wind up close to 200kmh given enough road, no idea what it cost him to do but he did have it for sale a while back

An unbroken, metric version of that spreadsheet would be nice...

That is an excellent read jonbouy.
I did a quick google of MPG of big V8s - nearly half (or double that- my maths is really bad) of what I get. So it is either heaps better or heaps worse.

cool factor is there tho.

My Ford pick-up gets just over 15mpg on a trip.
And I don't care.

The lexus into the hilux conversion is one of the most covered, the lexus motor is a reliable donk, but certainly not a show stopper on the HP
output.

at the moment my mileage has gone from over 2000kms a month to 500. going to be while till I have to buy another 10,000kms of ruc.

its a funny thing this buying new vehicles.Its not a linear relationship because we all know that sooner or later the old car is going to die...so you cant always say that its best to keep and old er car.So if you are going to buy a newer one you go all out to get what you want.Ie you buy the biggest ,the newest the most economical you can afford.Of course only you know what you can afford
