Default engine transplantation

One of my friends has a '90 premier padmini which is running on lpg (cooking gas).
we are planning to bring the car to our city where the car can't be run on lpg (cooking gas) being illegal.
What steps need to be done to convert the engine back to petrol apart from removing the lpg kit.Also i feel that the engine may be good as it was being run on lpg .any suggetions on this part ? what components need to be modified? anybody who converted their padminis to lpg ? any idea ?
One more is it possible to put in an 1800isz engine and grearbox into padmini.
any wat will this costs ? please help

Anything's possible, though I love your idea. You'll be going through tyres faster than you can fit them!

Ooh boy! Gotta love this forum!

In an automag they featured a padmini which had a turbocharged 1800isz engine & the conti gearbox & the suspension components & the brakes & the wheels from the conti. The 1800isz engine in padmini would be great considering that the padmini weighs considerable less compared to the conti. Man even the amby flies with that engine.

my cousin has a '85 deisel premier padmini.
he got it a used nissan 2.1 deisel. man it runs like a hot-rod.
but there is a constant problem - break failure. may be the torque is too much.
by the way, the whole transplantation costed him close to 40,000. (30,000 for the engine)in hyderabad. but i always felt the tranny's in-efficiency to use-up all the power of the nissan engine. (1400 cc tranny for a 2100 cc !!) but i never felt the transmission is going to give up. sometimes being crude also helps.
He should have also changed the tranny, may be that of an old merc. but that leads to whole lot of other things "he should have changed" .... lol... engine swap is not a joke.

Jokes apart, wouldn't it be cheaper & easier to buy a Conti for parts, etc?

Or you could fit a Premier Padmini bodyshell to the Conti, which shouldn't be too difficult, considering that both are body on frame & not monocoque.

I think the width & length would be an issue in doing this. You might have to modify either the Body or the Chassis. Secondly & most importantly don't forget to make sure you strengthen the chassis a hell of a lot to avoid flex due to the extra power & also strengthen the front subframe so it can handle the extra weight of the Conti engine.

Are you kidding or misinformed?

Both the Contessa and the Premier Padmini are monocoque (unitary body construction), not body on frame!

Maybe the old Ambassador (which is an older design than the 1959 Fiats) is body-on-frame.

OT but related : I once saw a Premier Padmini which had the bonnet elongated to almost 2 feet more. Asked the owner why, and he replied that his new engine wouldnt fit in the standard engine bay. Guess which engine?

The Tata Estate's!!

Amby is a unibody as well. Tata Estate is the only BOF car in India.

Default Engine transplantation with a massive engine

Talking of bigger engines in cars that weren't meant for them, a car-fanatic (like ourselves?) actually put a 27-litre Rolls-Royce Merlin V-12 engine into a car.



An engineer and a Merlin engine guru, Paul Jameson, first powered a car with one of these enormous aero engines. This happened in the late 1960s in the UK.

He used a brand new Rolls-Royce Meteor engine.
The Meteor is a derated version of the Merlin engine.
It powered our old 1965-1980 Vijayanta battle tank.
A 27-litre carbureted engine, the Meteor puts out 750 bhp @ 2500 rpm !

Paul Jameson used a Jaguar 420G differential & rear axle.
John Dodd, a gearbox specialist modified a GM Turbohydramatic 400 transmission,
changed to a Jaguar XJ6 rear axle and drove the chassis up to 288 km/h.

He then bought out the Meteor/Merlin-engined chassis from Mr. Paul Jameson
and plopped a custom fibre-glass body on it.

In a speed-run in Sweden, the car's bottom scraped the road, split the oil tank and caught fire. The fibreglass body burned to powder and the Meteor engine was damaged.

In a complete restoration process, the car now got a genuine Merlin engine and a Rolls-Royce radiator grille.



Rolls-Royce sued John Dodd in 1982 and won.
Mr. Dodd removed the grille and emigrated with his car to Malaga, Spain.

When I lived in Europe in the 1980s, I saw Paul Jameson's second RR Merlin-engined car. It was a blue mid-engined convertible with cream striping and six wheels -- two driven rear-axles.

After first seeing it in a Brit "Motor" mag, I embarked upon a dogged search (in that pre-Internet era).
Finally, I located the car in a car museum in a Dutch village called Raamsdonksveer near Geertruidenberg, Noord-Brabant.
The museum also had other celebrity cars: Elvis Presley's Cadillac, Winston Churchill's Humber Pullman and an Aston Martin DB5 that starred in a James Bond movie.

John Dodd owner of "The Beast" is now in his eighties. The car was first registered 35 years ago. It is now completely restored and back in the UK.



More about the Merlin
The Rolls-Royce Merlin 27,037 cc V-12 engine was a World War II aircraft engine.
Most illustrious among the different aircraft it powered was the
Armstrong-Vickers Supermarine Spitfire, a World-War-II single-seat fighter aircraft.



The Merlin version towards the end of WWII, put out 2,070 bhp on 150 Octane petrol, with a centrifugal supercharger.
It had gear driven overhead camshafts that actuated 48-valves, the exhaust valve stems being sodium-cooled.
The engine itself was liquid-cooled by a pressurized mixture of 70% water and 30% ethylene glycol.
It breathed through twin-choke gravity fed updraft carburetors with automatic mixture control.

illegal? get a kit which is certified by the RTO . 20k for kit, 26rs/lit for lpg. Dont we have lpg pump(s) at tvm?

1800 Isz into padmini's belly? Forget it, to many mods, and you need to find a very good mechanic at tvm. Get a toyota 1000cc or teh 137d engine.
