    Capacity Upgrade Kit VR38DETT 4.3L

    HKS has redesigned VR38DETT 4.1L Kit to upgrade it to 4.3L Kit.
    This kit is available from street use to circuit use.
    The following is the main redesigned features:

    1) Higher Torque - Allowable Torque: 150kgm
    2) Low Vibration - Equivalent Level to the Stock
    3) Longer Stroke - Stroke: 99mm
    (the world's longest level)


     Piston Kit
    • The billet-pistons have the ideal piston shape.
    • The special truss shape enhances the durability and makes ultra-lightweight pistons.
    • A squish area allows high rate combustion.
     Connecting Rod
    • The connecting rods were designed specifically for this kit. Engine modification is minimized.
     Crankshaft Stroke - 99.0mm
    • 9.0mm stroke without bore size change is incomparable.
    • Billet crankshaft.
    • The vibration generated from V6 engine is reduced to the degree to be not annoying by precise balance adjustment. (The included parts must be used together.)
    • The structure was designed to reduce a load to the metals so it can withstand the increased load to the main metal due to higher torque.
    • High efficiency heavy metal made balance weight reduces the weight and achieves high engine response.
     Compatible with Stock Bore Size - 95.5mm
    • The bore size is the same as the stock size to maintain the engine block rigidity and the ideal heat conduction for the optimal engine performance.
    • Modification of liner is not necessary so the cost related to this liner modification can be saved.
     Special Oil Jet
    • A special oil jet to cool down the pistons to the optimum level is newly designed.

    A billet-piston with squish area allows better combustion.

    A billet-crankshaft with high efficient balance weight reduces vibration, improves engine response, and decreases the weight.

    A special oil jet cools down the pistons to the optimum level.

    Balancing was performed based on the products included in this kit. Using other products with this kit may cause engine vibration.

    Recently, a lot of high performance cars feature electronic control of damping force adjustment. HKS assumed it would be best to keep stock electronic control system but add an additional flexibility and offers a height adjustable spring. HKS height adjustable springs kits are a great alternative to conventional springs. With included high adjuster it is possible to select different height suiting your car and enjoy more sporty ride.

    In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.


    Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Mr.Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name “HKS ”), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan.


    A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.


    HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools.  Clearly HKS was Driving Performance trends for Japanese vehicles.


    Since its beginning, HKS has been committed to providing well-integrated, reliable,and environmentally sound performance systems. Mr. Hasegawa ’s strong leadership, engineering genius, creativity and willingness to listen to customers are the pillars of the company ’s success. Monitoring consumer reaction and input on issues pertaining to material quality, external appearance, sound quality, and of course, performance, HKS stays in tune with automotive enthusiasts’ needs. Moreover, HKS’ products are designed to be user friendly for easy installation.


    Today the automotive aftermarket industry is filled with start-up companies following in HKS’ footsteps.  None however, can match the depth of engineering or manufacturing resources available to the talented, highly motivated and dedicated employees of HKS.


    For over a quarter century HKS products have been put to the test in drag racing, road racing, rallying, and top speed trials.  HKS equipped vehicles have captured numerous racing championships and hold claim to a myriad of competition records using many “off the shelf”, race proven HKS components.  As a result, HKS has been synonymous with “performance” in the automotive aftermarket industry for the past 35+years.
