One thing we pride ourselves on is race proven performance and reliability. Never settle for something that just “works”. All of our products were designed to meet our specifications and expectations. Tracks such as VIR, Road Atlanta, NOLA Motorsports Park, Sebring, and others create a ton of opportunities to find the weak spots for any build. We feel that if it isn’t good enough for our track cars, it isn’t good enough for your daily drivers or personal track cars.

MOTIV has been pushing the boundaries of reliability and performance on the stock bottom end for well over a year now. We made the ultimate decision to tear apart a few of the engines that had been put through their paces on the track, the stop and go daily life of a busy metropolitan city, and the high boost roll and drag race weekend fun many of you enjoy. The MOTIV Closed Deck Insert was developed in order to reinforce the motor from the potential weak spots we found. In each of the high horsepower engines we found one or more cylinders had become oblong / no longer true as a result of the power levels and the nature of an open deck block. Using our Romer Arm Coordinate Measuring Machine (CMM) we were able to create a precise insert to properly close the deck of the N54. This technology allows us to precisely measure the water jackets for proper fit and maintain proper coolant passages for more than adequate cooling. By CNC milling billet aluminum to fill the negative space of the short block we have effectively reinforced the engine to minimize stress on the cylinder walls and prevent cracks, ovaling of the cylinders, and maintain OEM coolant flow through to the head.

To ensure the integrity of your high horsepower motor we have developed a CNC milling program to modify the N54 short block to accept the MOTIV specific ARP 1/2″ head studs. With the increase in performance we are taking these engines to we felt it was better to over-engineer this part of the build for extended reliability.

Every motor goes through a rigorous evaluation process to ensure the quality and reliability of your new built motor is second to none. Before assembly each motor (whether your own or a core we supply) is torn down and inspected, washed, and measured to ensure everything meets our specifications. Every engine we assemble has a build summary with torque specifications, tolerances, and clearances are documented.

  • Disassemble motor and deep clean of all parts
  • Inspection and measurement of all parts to be reused.8
  • Install main girdle and tq plate
  • CNC machine block and install MOTIV closed deck assembly
  • CNC mill block for MOTIV ½” ARP head stud kit
  • Bore and hone block for proper piston clearances
  • Magnaflux crankshaft
  • Polish crankshaft
  • Measure main and rod bearing journals
  • Weigh and balance rods and pistons
  • Clean before final assembly
  • Install rod bearings and measure clearance
  • File fit rings for individual cylinders
  • Install main girdle with crankshaft bearings and measure for clearance
  • Install crankshaft with new front and rear main seals
  • Install pistons, rings, and bearings on the rods
  • Install each assembly into the block
  • Check crankshaft for breakaway and rotating torque
  • Final cleaning and inspection

All MOTIV engines will come completely assembled as a long block. We are committed to delivering motors that we can stand behind. In order to do so we feel that full assembly (including final torquing of the head and the proper timing of the cams) is essential to be done in house. As such our motors will come assembled with your choice of cylinder heads installed – stock or an upgraded cylinder head.

Many of the components used in this build are kept in stock, but some require individual engine specific measurements. Lead time on some of these products can reach approximately 6 weeks from the manufacturer.

CORE OPTIONS: In order to stream line the process we have sourced 6 and 8 bolt engine cores to be available for builds. If you would like to order an engine and keep your own, or have a damaged motor and need a core supplied you can select this option below. If you would like MOTIV to supply a core for the build and return your motor to us we do offer a core exchange. Once tracking shows your motor has been delivered we allow 14 days for your core to be delivered back to us. Upon inspection we will provide you a detailed report. If the motor meets our requirements your $1500 core charge will be refunded.
