   TOY-JET V8 LS1 CONVERSION FACTS                      

THE #2 MOST ASKED QUESTION ABOUT THE  TOY-JET CONVERSION PROCESS:

"How much weight does your LS1 Conversion kit add to the rear of the vehicle?"

Answer:
The LS1 conversion + Toy-Jet cooling system saves you 21lbs. over
your factory setup at the rear of the vehicle.

Let's do the math:

The Toy-Jet cooling system                                               47 pounds
Stock Porsche Wing                                                          12 pounds
Weight differential:          (Toy-jet cooling system) 35 lbs. heavier


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 yields 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.
