What do you think, will this engine fit into an early 911?

The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan 's

Diesel United, Ltd built the first engines and is where some
of these pictures were taken. It is available in 6 through 14 cylinder versions,
all are inline engines. These engines were designed primarily for very large
container ships. Ship owners like a single engine/single propeller design and
the new generation of larger container ships needed a bigger engine to propel
them. The cylinder bore is just under 38" and the stroke is just over
98". Each cylinder displaces 111,143 cubic inches (1820 liters) and
produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic
inches (25,480 liters) for the fourteen cylinder version.

Some facts on the 14 cylinder version:

Total engine weight:

2300 tons (The crankshaft alone weighs 300 tons.)


Length: 89 feet

Height: 44 feet

Maximum power: 108,920 hp at 102 rpm

Maximum torque: 5,608,312 lb/ft at 102rpm

Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake
Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260
lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That
is, more than 50% of the energy in the fuel in converted to motion.

For comparison, most automotive and small aircraft engines have BSFC figures
in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.

Even at its most efficient power setting, the big 14 consumes 1,660 gallons
of heavy fuel oil per hour.

A cross section of the RTA96C:



The internals of this engine are a bit different than most automotive
engines.

The top of the connecting rod is not attached directly to the piston. The top
of the connecting rod attaches to a "crosshead" which rides in guide
channels. A long piston rod then connects the crosshead to the piston.

I assume this is done so the the sideways forces produced by the connecting
rod are absorbed by the crosshead and not by the piston.. Those sideways
forces are what makes the cylinders in an auto engine get oval-shaped over
time.

Installing the "thin-shell" bearings. Crank & rod journals are
38" in diameter and 16" wide:

Do you have to have a tach for those or do you just count the roataion on your hands

[mpetry]

It's a bolt in. You'll need to buy the adapter kit and a heavy duty clutch. Might have to leave the hood open.

[pete3799]

Might want to put the high torque starter on her.

[aadrew10]

I don't think it will fit.

[Matt Monson]

I dunno. I think it might fit but you'll have some clearance issues on the decklid with that turbo up top. I suggest using a turbo tail and it should be fine.

[islandnine11]

I did that conversion last year, puts the balance out a bit so I installed a larger fuel cell (good for around a half a mile a tank)

[Dantilla]

The kit will NOT allow fitment in a short-wheelbase car.

Okay, here's the story:

It's a Sunday morning roads are dry. The wife and children have their picnic lunches packed and you have your new Pelican Parts T-shirt and hat on, which by-the-way fits perfectly and you have been dying to show off to your close friends.
You say with a grin, "alright people let's take the BIG car today!"

[NineOhOne]

I think an early 911 will fit in one of those bores.

[911TES]

Wayne, I think it will.

In fact, I'm pretty sure. Go ahead on the rebuild book and while you're at it I'll confirm compatibility...

[WIL84911]

Whoa! Looks like a good motor for that Toyota based Porsche!

[Wyvern]

yeah ... but , they will make us run a restricter plate ...

[al lkosmal]

Are those dilivar studs???

[Rob Channell]

It'll fit. You just have to scale the chassis up a little. Monster trucks beware. You could run over and smash a row of them.

[Porsche-O-Phile]

It seems like it would be insanely inefficient versus using diesel turbines, but I guess not...

[kidrock]

might need to relocate the DME relay.

[DanielDudley]

Doesn't rev.

[cgarr]

Imagine the size of the machines just to build that engine, think about it? just to build that crank the machine has to be 5 times as big as the part its self but thats just a guess, unless they are using some type of alien technology or somthing?
