    BASED UPON FINDINGS, ADDITIONAL REQUIRED PARTS AND THIRD PARTY MACHINE WORK:

    • 9A1 REMAN 'SHORTBLOCK' FROM PORSCHE: CALL FOR PRICING 

    • NIKASIL REPLATE TO OEM 3.8L DISPLACEMENT: CALL FOR PRICING - REQUIRES CYLINDER REBORE TO FACTORY 102MM DIAMETER AND NIKASIL PLATING AND THEREFORE AN ALTERNATE PISTON AND RING PACKAGE. IDEAL FOR SOMEONE IN A SPEC RACING CLASS WHERE ENGINE MODIFICATION IS NOT PERMITTED AND FACTORY SPECS MUST BE MAINTAINED.

    • NIKASIL REPLATE TO 4.2L DISPLACEMENT: CALL FOR PRICING - REQUIRES CYLINDER REBORE TO 105MM DIAMETER AND NIKASIL PLATING, ALTERNATE CONNECTING RODS, PISTONS, RINGS AND STROKER CRANK SHAFT.
      

DISPLACEMENT INCREASE (SEE NOTES BELOW):

  • INCREASE TO 3.8L  DISPLACEMENT INCREASE VIA CRATE ENGINE SWAP FOR 3.4L 981 / 987.2 OR 991 OWNERS WITHOUT THE 3.8L 
  • INCREASE TO 4.0L - DISPLACEMENT INCREASE FOR ALL 3.8L 997.2, 3.8L 991.1, 3,8L 981 SWAP / GT4 OWNERS - FEATURES UPGRADED 3.99L ENGINE CRANK, CARILLO CONNECTING RODS AND AFTERMARKET PISTONS.

  • INCREASE TO 4.2L - DISPLACEMENT INCREASE FOR AFOREMENTIONED 4.0L CUSTOMERS FEATURING INCREASED CYLINDER BORES OF 105MM PLATED IN NIKASIL (REQUIRES 4.0L ROTATING ASSEMBLY FROM ABOVE.)

NOTE: WE DO NOT OFFER A DISPLACEMENT INCREASE BEYOND 4.2L; SINCE THE INTRODUCTION OF THE 9A1 AND 9A2 ENGINE IN 2009 PORSCHE HAS NEVER BUILT A MOTOR LARGER THAN 4.2L AND NEITHER DO WE.

 

CYLINDER HEAD UPGRADES:

GIVEN THE AFOREMENTIONED DISPLACEMENT LIMIT WE EXHAUST ALL EFFORTS IN THE FORM OF BOLT-ON UPGRADES IN ORDER TO TRY AND MAKE THE MOST POWER AND TORQUE POSSIBLE WITHOUT SACRIFICING RELIABILITY.  THOSE OPTIONAL UPGRADES ARE:

  • X51 CNC PORTED CYLINDER HEADS : WE RECOMMEND A FRESHENING OF THE CYLINDER HEAD IN CONJUNCTION WITH ANY MAJOR ENGINE OVERHEAUL; IT FEATURES NEW X51 HIGHER RPM VALVE SPRINGS AND HARDWARE.  WE INCREASE THE FACTORY INTAKE PORT MATCH FURTHER TO ACHIEVE A FULL COMPUTER GENERATED OVERHAUL AND PRODUCE A REPEATABLE CYLINDER HEAD FOR YOUR 'AIR PUMP' THAT FLOWS AS EFFICIENTLY AS POSSIBLE IN THE SAME WAY EVERY TIME. 

  • X51 INTAKE CAM SHAFTS: THE ALTERNATE 991.1 X51 GTS POWER KIT INTAKE CAM SHAFT CONTRIBUTES TO AN INCREASE OF 30 MECHANINCAL HORSEPOWER AT THE CRANK; WITH LITTLE IMPROVEMENT TO TORQUE, ABOVE 5K RPM ADDITIONAL MECHANICAL HORSEPOWER CAN BE ACHEIVED.

  • 718 GT4 CLUBSPORT INTAKE MANIFOLD: THE PORSCHE MOTORSPORT 718 INTAKE MANIFOLD IS WORTH AN ADDITIONAL 30RWHP OVER 7K RPM VS. A CAR RUNNING THE STOCK 981 GT4 INTAKE MANIFOLD WITH SMALLER INTAKE RUNNERS.  WHILE THE 981 INTAKE DOES MAKE SUBSTANTIAL TORQUE UP TO 6000 RPM, IT COMES AT THE SACRIFICE OF USABLE HORSEPOWER AT THE TOP OF THE RPM RANGE.  IT IS FOR THIS REASON WE RECOMMEND AN INTAKE MANIFOLD UPGRADE FOR ALL NON 9A2 ENGINES.  

  • REVISED CAM PHASER HARDWARE: NEARLY ALL 9A1 ENGINES ARE SUBJECT TO FAILURE OF THE CAM PHASER FASTENERS THAT COMES AS A RESULT OF EXCESSIVE CHANGES IN INTERTIA OCCURING ToO THE VALVE TRAIN.  MORE SPECIFICALLY, THE BORES FOR THESE FASTENERS ARE TOO LARGE FOR THE OEM HARDWARE - WE MANDATE REVISING THIS HARDWARE ANY CHANCE WE GET BECAUSE IT SEEMS TO BE THE SINGLE BIGGEST REASON FOR FAILURE ON THESE ENGINES.

NOTES: (3.4L --> 3.8L SWAP REQUIRES CRATE ENGINE FROM PORSCHE, INCREASE TO 4.0L REQUIRES UPGRADED CRANK SHAFT, CONNECTING RODS AND PISTONS FOR THE AFOREMENTIONED CRATE ENGINE, 4.2L REQUIRES ALL AFOREMENTIONED UPGRADES PLUS NIKASIAL CYLINDER BORE INCREASE)


FORCED INDUCTION CONVERSION:

  • 991 TURBO S 'GT2 SWAP ': INCLUDES PARTS AND LABOR TO REMOVE AND REPLACE EXISTING 3.8L ENGINE WITH 991 BASED 3.8L TURBO S ENGINE, MODIFY & RELOCATE TURBO CHARGERS, INSTALL CUSTOM INTERCOOLER SYSTEM, CUSTOM AIRBOX, FRONT MOUNTED WATER COOLING SYSTEM, REMAP ECU AND PDK, DYNO & ROAD TEST.  SEE LINK: https://teambgb.com/pages/911-turbo-gt2-conversion
