SPORT TURBO UPGRADE SYSTEM                        (Page 2 of 3)




This Executive Order is granted based on results from emissions tests if
conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
However, the ARB finds that reasonable grounds exist to believe that use of
the Sport Turbo Upgrade System may adversely affect emissions of motor
vehicles when operating under conditions outside the parameters of the
previously prescribed test procedures.  Accordingly, the ARB reserves the
right to conduct additional emission tests, in the future, as such tests are
developed, that will more adequately measure emissions from all cycle
phases.  If such test results demonstrate that the Sport Turbo Upgrade
System adversely affect emissions during off—cycle conditions (defined as
those conditions which are beyond the parameters of the Cold—Start CVS—75
Federal Test Procedure}, this Executive Order shall be effectively rescinded
as of the date the test results are validated.  PFurther, if such test
results or other evidence provides the ARB with reason to suspect that the
Sport Turbo Upgrade System will affect the durability of the emission
control system, HKS USA, Inc. shall be required to submit durability data to
show that the durability of the vehicle emission control system is not, in
fact,   affected and/or that the add—on or modified part demonstrates adequate
durability.

In addition to the foregoing, the ARB reserves the right in the future to
review this Executive Order and the exemption provided herein to assure that
the exempted add—on or modified part continues to meet the standards and
procedures of Title 13, California Code of Regulations, Section 2222, et
seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF THE HKS USA, INC. SPORT TURBO UPGRADE SYSTEM.

No claim of any kind, such as "Approved by the Air Resources Board" may be
made with respect to the action taken herein in any advertising or other
oral or written communication.

Section 17500 of the Business and Professions Code makes untrue or
misleading advertising unlawful, and Section 17534 makes violation
punishable as a misdemeanor.

Section 43644 of the Health and Safety Code®      des as follows:

    "43644,   (a)  No person shall install, sell, offer for sale, or
    advertise, or, except in an application to the state board for
    certification of a device, represent, any device as a motor vehicle
    pollution control device for use on any used motor vehicle unless that
    device has been certified by the state board.  No person shall sell,
    offer for sale, advertise, or represent any motor vehicle pollution
    control device as a certified device which, in fact, is not a certified
    device.  Any violation of this subdivision is a misdemeanor."

IV.    DEVICE DESCRIPTION

       The HKS Sport Turbo Upgrade is a replacement turbocharger for stock

turbo vehicles.      It has a larger compressor wheel,    compressor housing, turbine

wheel, turbine housing and larger wastegate area.         It is designed to bolt

directly onto the stock exhaust manifold.

       The HKS Sport Turbo Upgrade System is designed for installation on the

following vehicles:

Model Year   Make          Model.        Engine Size—Liter(CID)    Part Number

1991—1992    Toyota        MR2 Turbo         2.0 (122)            6045RC—11328P

1990—1992    Nissan        300 ZX Turbo      3.0 (183)            6045EC—24751P

1991—1992    Mitsubishi    Eclipse           2.0 (122)            6045EC—4737 3N

1991—1992    Eagle         Talon             2.0 (122)            6045EC—47373N

1991—1992    Plymouth      Laser            2.0 (122)             6045EC—4737 3N

1991—1992    Mitsubishi     Galant VR4      2.0 (122)             6045EC—47573P




       The Sport Turbo Upgrade System consists of a turbocharger unit and

installation hardware.     The kit operates in conjunction with the original

equipment manufacturer (OEM) computer controlled electronic port fuel injection

and emission control systems already certified with the stock engine.              The

tune—up specifications remain the same.

       The 300 ZX Sport Turbo Upgrade System replaces the stock Garrett

Airesearch T—25 twin turbochargers with two Garrett Airesearch T—25 G twin

turbochargers.    Garrett manufactures all the rotating assemblies,        turbine

housing and wastegate swing valve while HKS manufactures the compressor housing

for the modified turbocharger system.        Appendix A illustrates the compressor

housing and the turbocharger system.        The modified turbochargers increase the


area ratios for the turbine and compressor from .58 to .64 and .42 to .80

respectively and increases the maximum boost from 8.5 psi to 14.3 psi.

       The MR2 Sport Turbo Upgrade System replaces the OEM turbocharger with a

Mitsubishi turbocharger model number TDOSG.       This turbocharger is built to HKS

specifications and has a turbine inlet of 8 square centimeters.

       The Mitsubishi Eclipse, Eagle Talon, Plymouth Laser,      and the Mitsubishi

Galant VR4 Sport Turbo Upgrade System replaces each respective OEM

turbochargers with a Mitsubishi turbocharger model number TDOSH.       This

turbocharger is built to HKS specifications and has a turbine inlet of 8 square

centimeters.   The Mitsubishi Galant VR4 Sport Turbo Upgrade System differs from

the Eclipse/Talon/Laser Sport Turbo Upgrade System only in installation

hardware.

 v.    SPORT TURBO UPGRADE SYSTEM EVALUATION AND DISCUSSION

       HKS USA, Inc. previously tested the Sport Turbo Upgrade System on a 1990

Nissan 300 ZX Twin Turbo with a 3.0 liter fuel—injected gasoline engine as

part of the HKS Performance Package P/N SR71XX—90000X.       The performance package

consists of an exhaust system, T—25 G Sport Turbo Upgrade System,      intercooler

upgrades, Vein Pressure Converter, 485 copm fuel injectors, HKS Power Flow air

filter system, electronic valve controller wastegate, spark plugs, oil cooler

and boost gauge.

       Comparative emissions tests demonstrated no significant increase in

emissions over stock despite installation of the Sport Turbo Upgrade System and

other modifications.

       HKS USA,    Inc.   submitted intake manifold pressure traces obtained during

exhaust emission tests showing both stock and Sport Turbo Upgrade System

equipped intake manifold pressure levels.       The traces indicated the intake

manifold pressure remained below atmospheric pressure thoughout the entire test
