 Pursuant to the authority vested in the undersigned bySection 39515 andSection 39516
 of the Health and Safety Code and Executive Order G—02—003;

. 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 Sectlon 217156 of the Vehlcle
 Code for all 1980 to 1991 model year VW Vanagons.

   This conversion kit is designed to provide all the necessary parts to replace the stock 1980
 . to 1991 model years VW Vanagon engine with a used 2002to 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 | Low Emission Vehicle
   (LEV | LEV)or Low Emission Vehicle I Ultra Low Emlssmn Vehicle (LEV I ULEV) exhaust              |
   emissions 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 appllcable 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 vaives 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. The 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
 fuel 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 vaives 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 submitted emission test data generated on a 1990
model year VW 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).
