LS-Swap - the most popular engine swap in the tuning scene!

Recently updated on February 15, 2021 at 02:42 am

An Motorswap is known to be the exchange of a series engine for another engine. And when you deal with the scene, you often hear the term 2JZ-Swap and even more often the term LS-Swap. Both are names from the tuning area and the LS exchange is mainly practiced in the USA and is known from there. LS Swap describes the exchange of a certain type of engine. The term engine swap is of course interesting in this context. As mentioned, the engine swap in the tuning area stands for the complete Engine replacement (not the increase in performance of an engine) and describes the installation of a different, mostly more powerful engine. If the motor swap concerns an LS motor from General Motors, the term LS swap is used. The LS motor and LS swap are discussed in more detail below.

LS Motor - what makes it so special?

General Motors introduced the small-block V1995 to the American market in 8. The small-block V8 engine was used for trucks and rear-wheel drive vehicles. General Motors' LS engine is a compact V8 that has been used in numerous series. The engine was built into a wide variety of cars and is available in many variants on the market. The LS6, for example, is more powerful than the LS1. In addition, the small-block V8 engines from General Motors are divided into generations and run under various terms such as LM and LT. However, the following is not about the individual General Motors engine variants, but about the LS swap.

Motor exchange for tuning purposes

If you want to tune your vehicle, you can do a lot of fixtures, exchange vehicle parts and make visual changes for personalization purposes. Not every exchange in the engine area is called an engine swap. Anyone who only uses a more powerful engine that the manufacturer of the vehicle intends for the vehicle anyway will not necessarily speak of an engine swap. Engine swap is usually used as a term in the tuning scene when a higher level of difficulty, such as the installation of non-brand engines, is carried out. In Germany, however, engine swaps and LS swaps mostly fail because of the TÜV, which is accordingly critical of such conversion work. The replacement of a vehicle engine must not lead to a deterioration in exhaust gas values, which already destroys many turbo conversions. After the engine swap and after an LS swap, an exhaust gas report is necessary, which can lead to a negative result and also costs a lot. Furthermore, an engine swap often requires modifications in the engine area, which are not permitted in Germany in terms of safety and are not approved by the TÜV. In the USA, however, the legal situation looks different (better), as always, and LS swaps and engine swaps are regularly carried out there.

LS1 motors to LSX variants

The different LS motor variants are available in different price categories. If you are looking for an LSX drive, you will almost always have to reckon with a five-digit amount. The LS1 variants that were built in the 1990s (late 90s) are particularly cheap. Anyone willing to spend the $ 5000 on an LS motor can purchase an LS3 motor. Thanks to the compact dimensions of the LS motors, they weigh less than other V8s. There are also versions made of aluminum that are even lighter. The motors for an LS Swap are considered to be durable, powerful and should have a high mileage compared to the standard. The engines are also popular because their compact dimensions mean they can be easily installed in someone else's car chassis.

LS Swap - popular in the US

In addition to the general engine swap, there is the swap of an LS engine from the well-known group General Motors popular in the US. Regardless of the vehicle model, the LS engine from General Motors is built into almost every car. Asian vehicles, a Golf, a Hyundai or a BMW E30 equipped with an LS motor. The LS Swap is so widespread in the USA that there are even systems (LS Swap Systems) to buy in stores. The systems are in Tuning magazines advertised and they should induce the installation of the GM LS engine in the desired chassis. Of course, the purchase of the LS Swap Kit does not mean that the installation can only be carried out in GM cars. As already mentioned, import vehicles from Asia or Europe or from anywhere else can be used. But Asian cars in particular are often used for the LS Swap. However, it is also popular to add the legendary 2JZ power unit from the Toyota Supra to an American or European vehicle. Here one doesn't take much from the other.

LS Swap - why is it popular?

In the USA, the LS motor has enjoyed great popularity since it was presented. The engine is available in large numbers and can also be found in countless scrap yards, for example. There is a large selection of compact V8 engines and comparatively inexpensive. The purchase of cheap components is also easily possible in the USA. The V8 engine is not only compact and suitable for an engine swap, it is also resilient and powerful.

Planning as a Y block

If you want a V8 drive that can withstand more than other V8 drives, you should plan the LS as a Y-block. The LS engine from General Motors is not only extremely robust, but also offers a large selection of variants. The interested tuner can choose anything from a 4,8-liter engine to a 7,4-liter engine (LSX engine) for the LS Swap. The 4,8 liter LS engine, for example, was used as a pickup engine. Thanks to the large selection of LS motor variants, even tuners with a small budget can find what they are looking for. In addition to the advantages mentioned, the compact V8 also offers efficient engine performance.

PS:  So that engine Swap can be done safely, you need a good motor stand. more information is available here! And iOnce the conversion has been carried out, an acceptance test must be carried out in order to legally participate in road traffic. And the insurance company must also be informed about the engine replacement. If this does not happen, the Service reduced or completely refused .
