More for the not so faint at heart. Oh the humanity !

[Pete000]

Never gets any easier to see things like this !

[jwetering]

And it's a SWB car too. That's like the icing on the cake.

Cars like this help me to imagine what the sports car club in hell looks like. The guy who built this thing would be treasurer.

[Hotwatermusic]

Sweet. Finally get to use this.

[sc_rufctr]

Looks like a victim of the 80s... We should all learn some lessons from the past.

Keep you car all Porsche and as original as possible I say.

[inthemeantime]

Some people are wired all wrong.

That is a very big manatee. Maybe it's the liquor but I find this very funny.

[DanielDudley]

If it runs well, it would make a good RSR look conversion.

But then, there is an ass for every saddle, or so I hear.

[flatsixjunky]

I've had a cold for a few day's and when I saw your poster I laughed so hard I choked.
It's so absurd it's hilarious.

Take care.

Is the Chevy V8 a lot heavier thant the flat six....? If so, should be a very viscious car in a thight curve at speed...!

A small block with cast iron intake and exhaust is about 570 pounds. With aluminum intake, headers, and modern aluminum heads it is quite a bit lighter then that.
In other words the small block Chevy is quite a bit lighter...

...but
Then you add the cooling system, the raised center of gravity, the decreased reliable lifetime, and the loss in value...

[McLovin]

no way is a SBC lighter than the flat 6 that came in that car.

[HawgRyder]

If you use an aluminum block and heads, manifold, rods...etc...you can get the weight of a small block ( up to 440 cu in! ) to about 320 pounds.
Bob

ps...that would get you about 550 HP as well.

The 911 engine is heavier then you would think. If you machined all the cooling fins off of it and put a water jacket over it it would weigh quite a bit less.
A modern small block is a fairly lightweight unit. Add an aluminum block and it is pretty easy to pick one up by yourself.

- The Chevy has to add all of the external cooling system and water which isn't listed here.
- The Porsche has to add the external oil system which isn't listed here.
- A lot of Porsche engine weights don't include the intake manifolds and the headers which are always part of the Chevy specification.

The 911 motor is a over 450 pounds. The joy of the flat 6 isn't in its light weight. It is in the indestructibility of it. (What other engine in the world has 6 pistons and 8 main bearings?)

[McLovin]

I've had both out of the cars, 911 and SBC. My SBC had aluminum heads, edelbrock manifold and carb and steel headers.

Taking it out of the car, putting the engines on stands, in the back of pickups for transport, moving around the garage, etc., the SBC sure seemed a heck of a lot heavier than a 911 engine.

For ex, we could easily lift the 911 engine into a pickup or SUV with 2 guys. no way could the 2 of us get the SBC lifted.

I just don't see how a big iron block V8 is going to be lighter than a smaller all alloy 6 cylinder.

they're both boat anchors compared to a 914 engine, tho!

[kidrock]

I've repeatedly read about how the SBC is lighter than the flat 6...I always found it hard to believe, but it's hard to dispute some of the experts.

I think it would be cool to have that much juice...but Man, that car is Fugly.

[Formerly Steve Wilkinson]

"...big iron block V8..."

I don't think anybody's talking about an iron smallblock in this conversation.

[lucittm]

Could someone out there with their engine out of the car and going onto, or coming off an engine stand, weigh the engine. It can be done with two bathroom scales and a pallet. Or if you have the sophisticated scale that hangs from a chain, that would be better.

Thanks,
Mark

Don't have an extra chebby or pcar engine laying around but here's weight info provided via toy-jet.com (conversion car)

Weight difference 3.0 liter Porsche engine -vs- GM LS1 5.7 liter Corvette engine

Stock 3.0 Liter Porsche Engine

My fully dressed 1980 3.0 Porsche engine ready to install weighed 472 lbs. Factor in the
weight of the oil in the 10 quart oil tank mounted at the rear of the vehicle (which will need
to be removed) needed to support the 3.0 engine, then your engine plus oil tank weight jumps
up to 490.5 lbs. at the rear of the vehicle.

Let's factor in the oil and tank weight.

One gallon of oil is 7.4 lbs.
Ten quarts is 2.5 gallons
2.5 x 7.4 lbs. = 18.5lbs

18.5 lbs. + (3.0 ltr. engine wt.) 472 lbs. = 490.5 lbs. at the rear of the vehicle
(not factoring in the weight of the oil tank and lines which will be removed).


All Aluminum LS1

A fully dressed 2000 LS1 5.7 liter Corvette engine ready to install with the engine computer and
wire harness, complete exhaust system, engine mounting brackets, AC compressor, alternator,
custom water pump adapter, transmission adapter plate and flywheel weighed 434 lbs. This is
a rear engine weight savings of 56 lbs. over the Porsche 3.0 engine. I did not weigh the above
engines with the transaxle or clutch assembly bolted to either engine. These parts would be used
for both installations and their weights would obviously cancel.
LS1 = 434 lbs. at the rear of the vehicle

Now let's factor in the Toy-Jet Cooling system

In conclusion:

Weight of LS1 engine -vs- the Porsche 3.0 stock engine: 56 lbs. lighter
Weight of (ToyJet) cooling system -vs- stock Porsche Wing - 35 lbs. heavier
21 lbs. total weight difference

A porsche 911 equipped with the LS1 conversion and Toy-Jet cooling system installation yieilds a combined weight savings of 21 pounds lighter at the rear of the vehicle.

Hence:
No added cost of beefing up your rear suspension to off set any added weight.

Performance Comparison

The heart of the Porsche 1980 SC is a 3-liter, 6-cylinder, alloy boxer motor, It will go
from 0 to 60 miles per hour in 5.8 seconds. The quarter mile dash takes just over 14
seconds, and top speed is 149mph.

LS1 Supercharged (low boost) 1980 Porsche 911 SC is a 5.7liter V8, alloy motor. It
will go from 0 to 60 miles per hour in 3.7 seconds. The quarter mile dash takes just
over 11.5 seconds, and top speed is right at 190 - 200 mph. Not bad for a vehicle
conceived and built in a home garage.

[Tonka]

ghetto!!

[Formerly Steve Wilkinson]

There is no way on god's green earth that a low-boost LS1 will drive anything to 190-200 mph. I'll buy everything else--weights, etc.--but when you're talking horsepower pushing flat-plate area with drag rising at the square of the speed, I think it is, all you need is a 20-year-old Texas Instruments calculator to tell you that'll never happen. 165, 170.
