More Straightforward Transmission Swaps with Adapter Plates

Professionally engineered adapter plates simplify any conversion project 

For simplifying the process of a transmission swap, adapter plates are advantageous for ensuring successful conversions. While every component is important in a swap project, the adapter plate cannot be discounted. When an engine and transmission combination is not readily available from the factory, an aftermarket adapter plate bridges the connection.

The most common adapter plates cater to LS swaps, enabling the versatile and popular LS motor to work seamlessly with a wide range of transmission options in almost any vehicle. However, adapter plates can facilitate compatibility between nearly any engine and transmission combination, offering endless possibilities for car enthusiasts.

Opting for professionally designed and manufactured adapter plates, instead of constructing them yourself, streamlines the process, saves time, and ensures more reliable results. They eliminate the guesswork involved in a complex and sometimes time-consuming fabrication.

While adapter plates can be purchased individually, they are often part of adapter kits. These kits include various components such as flywheels, mounting hardware, motor mounts, crossmembers, and more, to provide a more complete solution for conversion projects.

Reduce Costs in Your Next Build

Typically, swapping an engine from a specific manufacturer requires a transmission from the same manufacturer, which can be expensive. For instance, if a 2JZ or LS swap requires a V-160, R-154, or T-56 Magnum transmission, the cost can easily surpass that of the motor itself. However, using an adapter plate, like those offered by G Force Performance Products, opens up more affordable transmission options. This is particularly beneficial for budget-conscious mechanics or do-it-yourselfers. Additionally, the "bolt-on" design of G Force adapter plates saves valuable time.

Currently, G Force provides adapter plates and kits for Cummins, LS, LT, SBC, and Honda K Series motors, accommodating a variety of transmission options.

  • Mounting Hardware

Additional details about the kit:

  • Features a bolt-on flywheel without the need for adapters or spacer bushings.

  • The flywheel is a billet steel kit weighing approximately 30 lbs, preferred for 90% of all available builds, unlike lighter aluminum flywheels used in some conversion kits.

  • Compatible with any OEM or aftermarket 350Z clutch assembly.

  • No modifications required for the transmission.

  • Some heavy wall bellhousings may require minor clearance trimming for the flywheel ring gear, typically removing approximately 0.06 inches over a small area.

The LS swap adapter kit for a Frontier/Xterra allows you to mate a Nissan Frontier or Xterra 6 speed manual transmission to an LS Series (i.e.; 4.8, 5.3, 5.7, 6.0, and 6.2 liter gen III or IV Vortec engines). These transmissions were available from 2005-2015 in the Nissan Frontier and  Xterra with V6 VQ40DE engines.

The kit includes—

  • Custom Steel Flywheel
  • 3/8" Steel Powder Coated Adapter Plate
  • Pilot Bushing Adapter
  • Throwout Bearing Spacer
  • Mounting Hardware

The direct bolt-on flywheel is made from billet steel and is a single-mass flywheel and can be used with any OEM or aftermarket Frontier/Xterra clutch assembly. The flywheel weighs about 30 lbs. G Force sells a GF-LSFB-SET flywheel to crank bolt kit to streamline the install.

These transmissions are a great alternative to the T56!

Our LT, SBC, or K Series version of the G Force Adapter Kits

Keep in mind that even with Conversion Adapter Kit such as those shown above, LS, LT, or SBC conversions vary for each application and are a demanding process. Modifications may be necessary for every component that contributes to the motor's operation in the new platform. However, professionally engineered components help simplify at least some aspects of the conversion and are well worth your consideration.

G Force also provides swap and conversion kits for Cummins, Porsche 944, Mustang to SBC or LS, and more.
