  Vehicle Code; and

  Pursuant to the authority vested in the underSIQned by Section 39515 and Sectlon 39516
  of the Health and Safety Code and Executive Order G—14—012;

  IT IS ORDERED AND RESOLVED: That installation of the Stephan‘s Auto Haus VW
  Vanagon 1.8 Liter Turbo Engine Conversion Kit (Conversion Kit), manufactured and
  marketed by Stephan‘s Auto Haus, 3950 Attawa Avenue, Sacramento, California 95822,
  has been found not to reduce the effectiveness of the applicable vehicle pollution control
  systems and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle
  Code for all 1980 to 1991 model year VW Vanagons and 1980 to 1991 model year VW —
  Transporters (Transporter must be currently registered with the California
  Department of Motor Vehicles prior to kit installation).

  This conversion kit is designed to provide all the necessary parts to replace the stock 1980
  to 1991 model years VW Vanagon or Transporter engine with a used 2002 to 2006 model
  year 1.8 liter VW turbocharged engine applicable to the Jetta, Golf, GTI, Beetle Turbo S,
  or Audi TT. These engines are certified to Low Emission Vehicle I Low Emission Vehicle
  (LEV | LEV) or Low Emission Vehicle | Ultra Low Emission Vehicle (LEV 1 ULEV) exhaust
  emlssmns standards for passenger cars.

  This conversion kit includes the following components: an engine to transmission adaptor
_ plate, a flywheel for a manual transmission or a flexplate for an automatic transmission, a _
  modified turbo outlet pipe, customized SAH silicon air intake plumbing, a customized
  engine bay wiring harness, a customized exhaust system using the VW stock catalyst or
  legal aftermarket catalyst applicable to the 2002—2006 model years 1.8L VW turbo charged
  engine, and a Chrysler/Dodge closed air filter box with part numbers 4458052 and
  4458053 or California legal aftermarket air filter assembly. These original.1.8 T engine
  components are also supplied: carbon canister, leak detection pump, MAF sensor, coolant
  temp sensor, and oxygen sensors. Also, all sensors, solenoids, and valves related to the
_ evaporative emissions, air intake, and turbo systems are included. A thermostat and
  housing are also included as is the intercooler and cooling fan. . Optional upgraded
  intercooler kit, P/N WATOO1006, can be used instead of the factory intercooler mentioned
  above, kit includes replacement intercooler core, intercooler radiator, cooling fan,
  intercooler water pump, silicon pipe joiners, modified boost pressure housing, and a new
  intercooler water reservoir. The conversion kit does not include an ECU (with only the
  immobilizer removed) or the donor motor. Automatic transmission Vanagon‘s must use a
  Manual transmission ECU:


Air cooled Vanagons must have a 1983 or newer Vanagon water cooled system installed
and water cooled Vanagons will retain their original cooling system. The original Vanagon
fue! tank is retained and connected to the stock 1.8T evaporative emissions systems
carbon canister and leak detection pump. The following Vanagon Stock components are
removed: the engine, exhaust system, intake system, engine bay wiring harness and ECU.
A check engine light must be installed and wired to the new VW ECU. The following
OBD II monitors may be logged as trouble codes: Instrument cluster monitor, ABS system
module, and air bag module. The Vanagon hardware does not support these electrical
functions. The VW 1.8 liter turbo charged engine retains the stock catalyst or California
legal aftermarket catalyst. Also used are stock solenoids, sensors, and valves related to
the operation of the engine, air intake system, and turbo system. The stock intercooler and
stock evaporative emissions components including the carbon canister and leak detection
pump are also used. The SAH silicon air intake hoses and emission related hoses are
routed so as to fit properly in the engine bay within these two systems all stock sensors,
solenoids, and valves are used in their proper locations and installed as per VW diagrams.

This Executive Order is valid provided that the installation instructions for the Conversion
Kit will not recommend tuning the vehicle to specifications different from those submitted
by the device manufacturer.

Changes made to the design or operating conditions of the VW Vanagon 1.8 Liter Turbo
Engine Conversion Kit, as exempt by the Air Resources Board, which adversely affect the
performance of the vehicle‘s pollution control system shall invalidate this Executive Order.

Marketing of the Conversion Kit using any identification other than that shown in this
Executive Order or marketing of the Conversion Kit for an application other than those
listed in this Executive Order shall be prohibited unless prior approval is obtained from the
Air Resources Board.

This Executive Order is granted based on prior submitted emission test data generated on a
1990 model year /W Vanagon modified with the Conversion Kit. Test results showed that
emission levels, with the Conversion Kit installed, met the applicable emission standards
when tested using the Cold—Start CVS—75 Federal Test Procedure (FTP) test cycle.
Examination of the OBD II system showed the Conversion Kit did not affect OBD II system
operation. Results from emission testing conducted at Automotive Testing and Development
Services, Inc. of Ontario, California are shown below (in grams per mile).
