J-101
Turbocharger Jet
Engine
Our J-101 Jet Engine is built around a large truck
turbocharger.
The maximum thrust essentially depends on the size of turbocharger you are able to
obtain.
The J-101 can either be built from scratch, or you can buy completed
components from us and piece it together much more easily. If you are
going to go the DIY from scratch route, please note that it requires a
fair amount work in construction and is best suited to the true
do-it-yourselfer who is familiar with welding stainless steel and
metalwork.
The turbocharger is the most expensive part of the engine and the
remainder of the materials required to complete the engine are fairly
inexpensive if you fabricate them yourself. Good quality used
truck turbochargers can be purchased from just
about any auto wrecking yard or used automotive parts dealer for about
$50 to $400 - or if your budget permits, you can always purchase a brand
new one. Depending on your budget and application for the engine,
you can upgrade the engine performance by afterburning it, or add on a
multitude of additional features and capabilities. Properly built using
a decent sized turbocharger, the J-101 can have a maximum thrust up to
about 400 pounds.
The J-101 Jet Engine will be available in kit form, as
individual parts, or you can simply order the plans and fabricate
everything on your own.

Jet Engine Plans
We offer 3
different sets of Jet Engine Plans.
The J-101 Plans are for building the turbocharger based turbine jet
engine mentioned above. The plans are in 8.5" x 11" book
format and cover all the information needed to build the engine
including alternate parts sources, etc.
The other two Jet Engine Plans, our J-20 & J-130 Jet Engines, are
considerably different than the J-101 turbine engine.
First of all, they have no moving parts whatsoever. There is nothing to
wear out, and there is no complicated support equipment such as fuel
& oil pumps, bearings, or radiators found on turbine engines, or
reed valves that wear out & break found on pulsejet engines.
They are known as 'Pressure Jet Engines' and have also been called
'Static Ramjet Engines (because they produce power statically (when they
are stationary) where true Ramjet engines only produce power when moving
at very high speed).
At the present time, we do not sell J-20 or J-130 engines or parts, only
the plans.
The plans for the J-20 & J-130 are large, 1:1 scale drawings (over
16 feet long for the J-130 and over 8 feet long for the J-20).
The engines are fabricated from just sheet metal and tubing. If you are
good at with metalworking & fabrication (cutting, welding, forming)
you can build these engines. Being 1:1, full size drawings, these plans
can simply be placed on top of your sheet metal and the parts cut right
out. It is a great metal shop project for the more advanced hobbyist.
The original engine & designs were produced by a close friend of Bob
Lazar's, Eugene Gulhareff. Until his death, Eugene built & sold his
engine for decades and met Bob in the late 1970s. Bob occasionally
worked with Eugene building engines and also sold plans with some minor
modifications he incorporated for Go-Kart & small vehicle use at car
shows and race events.
These plans incorporate the performance changes Bob made back then and
the engines actually put out about 15% more thrust than advertised. The
J-20 & J-130 engines are controlled by a simple ball valve
regulating propane flow to the engine which allows them to throttle from
idle (essentially zero thrust) to 100%. The engine does get red hot
during operation so it cannot be built into an enclosed area unless
copious amounts of ventilation are provided.
