LS 300zx Swap
What is an LS 300zx Swap?
The LS 300zx Swap is a prevalent engine swap. It involves putting a General Motors (GM) LS engine into a Nissan 300zx, also known as Z32. The 300zx z32 is a Japanese sports car manufactured between 1989-2000. Nissan originally offered it with a 3.0 liter naturally aspirated and twin-turbo engine. Nissan offered an auto and manual gearbox variant of the z32.
The manual 300zx transmission is a 5-speed that could withstand a beating. Its durability makes it a perfect candidate to mate to the GM V8 Engine known as the LS. Designing a way to bolt a Z32 transmission to an LS creates viable options for a 300zx engine swap. With the availability of an LS 300zx swap kit, many Nissan enthusiasts can have the sporty looks of a 300zx with the reliable power of a GM V8.
The LS is a family of GM engines that debuted in 1997. GM originally called it the Gen-III Small-Block for cars. The truck version was known as the iron-block, while they introduced the lighter weight, all-aluminum LS1 for the new C5 Corvette.
GM produced these engines between 1997 and 2004 in the US. In addition to the C5 Corvette, they came factory installed in the Chevy Camaro as well as Pontiac's Firebird and GTO. Although GM referred to this V8 family of engines as Gen III and Gen IV, enthusiasts quickly saw the potential from their tremendous performance. They nicknamed the group of engines LS.

LS 300zx swap compatibility
A great feature of the LS series is the compatibility between different LS engine generations. That flexibility creates opportunities for devising less expensive but advantageous upgrades. For example, fitting an LS2 head on an LS1 engine adds more horsepower. Therefore, interchanging the parts is an easy way to maximize the potential of the swap. Also, having the choice between the lightweight all-aluminum or the heavier cast iron engine makes this platform desirable in a wide variety of projects.
LS 300zx swap transmission options
GM's go-to manual transmission is the t56. This transmission came factory in 98-02 Camaro/Firebirds, Corvettes, and GTOs. The availability of these transmissions is lacking; therefore, the price has skyrocketed. The scarcity and cost of the t56 are why G Force has engineered transmission swap kits to allow the use of other popular transmissions. Here, the Z32 transmission is worth considering. It is robust yet compact. Because it costs a fraction of a t56, the 300zx transmission is a frequent choice for the budget-conscious. To complete the LS 300zx swap, bolt-on adapter plates like the one from G Force Performance Products make the Z32 transmission connection to an LS motor a breeze. G Force is an established aftermarket resource known for the strength, durability, and reliability of the parts we manufacture. We offer an array of transmission and suspension parts engineered to make complex projects such as the LS 300zx swap more straightforward to complete.
