What You Need to Know About an LS Conversion

An LS conversion involves the swapping and installation of engines into an existing vehicle. LS stands for any engine manufactured by GM. This is the primary V8 engine manufactured by GM and widely used in the Chevy Corvette beginning in 1997. It’s a popular choice for aftermarket engine swaps also known as LS Conversions.

Can I put any type of engine in any type of car?

You could potentially swap engines of different makes to almost any model of car. However, the cost may be a factor in that decision. To avoid wasting money on an LS conversion, be sure to talk to a reliable engineer before servicing the vehicle. Based on your budget and the performance you’re looking for, an experience professional can help you determine which engine will work best.

What is the estimated cost for a custom engine swap?

Custom swapping an engine varies significantly in cost depending on the involved materials and cars as well as the amount of labor necessary for completing the swap. Prices can range from as low as $1,500 to higher than $12,000.

LS Conversions with G Force Performance Products

G Force Performance Products is a leading designer, manufacturer and distributor of automotive components for LS conversions and other accessories. Our products can help you upgrade from stock parts and swap out components from your car. We also offer adjustable transmission mounts, crossmembers, bellhousing adapters, flywheels, exhaust parts and more! The following products are ideal for LS conversions, increasing the stability of the vehicle’s new engine.

G Force Adjustable Transmission Mount Replacement

Our Adjustable Transmission Mount offers an innovative simplicity for improved efficiency and stability. Because it allows for an offset of 1 to 2.5 inches, this product is ideal for LS conversion applications requiring the moving of your transmission from its stock location. The simple, bolt-in mount design also prevents swapping misalignment. As a result, your transmission will accurately align with your drivetrain without issue. We have designed the adjustable transmission mounts with strong mounting hardware and polyurethane bushing. It fits most manual or automatic GM RWD transmissions. Additionally, the mount is adjustable before securing the slide bolt with an install height of 1.75 inches, so you can accurately place the assembly. NOTE: Check your current transmission mount’s pattern dimensions to confirm it matches prior to purchasing a mount replacement.

Our Products

This list of components for LS swaps brings us to where our products fall in line with solving the complex problem that is an LS conversion. For traditional style LS conversions, we offer transmission crossmembers and some motor mounts for specific conversions. The adapter plates that we offer solve very specific problems for customers. IE, customers who want to convert a specific transmission and motor into any platform. Although these kits might allow customers to choose different transmission and motor combinations, it does not solve a customers desire to convert these specific motor and transmission combinations into specific platforms or cars. Pairing these adaptor plates with transmission crossmembers or motor mounts would allow them to be considered “LS conversion kits” as oppose to “LS Conversion components”

Our transmission crossmembers allow customers to conversion transmissions into specific applications, but solves no other concern.

G-Force motor mounts allow customers to conversion specific motors into specific applications or platforms but solve no other concern.

In addition, our transmission adaptor plates allow our customers to combine specific motor and transmission combinations but solve no other concern.

Customers who choose our specific components are solving one of the many concerns they have when converting their motor or transmission. Each concern is very specific. As a whole, we can say that our products offer quality solutions to specific problems, but also offer specific benefits for each application. Establishing product benefits would be easiest knowing which specific products we want to analyze.  

As a whole, our product quality is better or equally as good as our competition with very competitive pricing.
