Swiss engineer Dr. Alfred Buchi is credited with developing the first exhaust-driven turbocharger, sometime around 1912. By 1915, he published a proposal for employing a turbocharger on a diesel engine, but the idea was mostly ignored for the next few years. The first realworld applications were in aviation, where turbochargers helped aircraft engines build power […]
LS ENGINE SUPERCHARGER TYPES AND HOW TO CHOOSE
Superchargers come in many different shapes and sizes, but they are related by a common attribute: They generate boost pressure via an engine-driven mechanism. Typically, superchargers are driven by a belt connected to the crankshaft. When it comes to the commercially available superchargers for LS engines, there are two basic types: positive displacement and centrifugal. […]
INTRO TO LS ENGINES & FORCED INDUCTION
In general terms, and assuming everything else is equal, an internal combustion engine with larger displacement flows more air than a smaller-displacement engine. The engine with the greater airflow makes more power. This Tech Tip is From the Full Book, HOW TO SUPERCHARGE & TURBOCHARGE GM LS-SERIES ENGINES. For a comprehensive guide on this entire […]
Camaro and Firebird LS Swap: Initial Start-Up Guide
I am pretty sure that by now you are ready to turn the key and fire up the engine. Now take a deep breath and slowly walk away from the car. Yes, that’s right. Walk away. This may sound counterintuitive because you’re itching to get your LS-powered F-Body car on the road. However, the last […]
Camaro and Firebird LS Swap: Exhaust and Induction Guide
Often the exhaust portion of a build is left to the very end when everything is bolted up; it’s often quite literally an afterthought. As I stated in Chapter 2, a sound strategy is to select the engine mounts, transmission crossmember, headers, and related parts as a kit. The header routing and clearance of the […]
Camaro and Firebird LS Swap: Wiring Guide
As with other LS components, a massive number of computercontrol, harness, and electronic equipment options exist for this popular engine platform. Most swappers adapt the factory electronics to the particular F-Body, but installing aftermarket controllers are certainly an option. If you don’t want to adapt the EFI and drive-by-wire gas pedal technology to your F-Body, […]
Firebird and Camaro LS Swap: Transmission Guide
You have a universe of transmission options for swapping an LS into an early F-Body, and like other components of your equipment package, the transmission you select should be based on application. Most owners stick to a transmission that has a compatible bolt pattern for the LS because it’s convenient and many superb transmissions simply […]
Firebird and Camaro LS Swap: Cooling System Guide
A high-performance LS engine generates much more heat than a Chevy Gen I small-block engine or a Pontiac V-8 that originally came in many of the F-Body cars, so you need a cooling system that effectively and efficiently dissipates and manages the heat. Therefore, you need the correct components, adequate capacity, and proper calibration for […]
Firebird and Camaro LS Swap: Fuel System Guide
As has been mentioned before, the LS engines were not expressly designed to go between the frame rails of the first- or second-generation F-Body. Every modern LS engine is fuel injected while every early F-Body car carried a carbureted engine. Fuel injection has many different requirements than carbureted engines. To run the Efisystem on an […]
Camaro and Firebird LS Swap: Front-Drive Accessory Guide
Many front-drive pulleys and kits are available from the aftermarket to suit a particular LS engine setup and accessory arrangement. Obviously, the LS engine was not designed specifically for first- or second-generation F-Body engine swaps. However, this engine series delivers exceptional performance, and with the correct complement of parts and some chassis modifications to the […]
