928 Automatic and Five Speed Conversion

For over 25 years, Renegade Hybrids has been offering Small Block Chevy conversion kits for most model Porsches. About 15 years ago, the 928 joined the Renegade arsenal as we introduced the "German Corvette" to some "American Muscle." The 928 Small Block Chevy kits offered a huge increase in power and reliability, more room to work around the engine, lower maintenance costs, and less weight.

In the late 90's, GM abandoned their 1950's technology Small Block Chevy design and introduced (arguably) one of the best V-8 engines every built. They took the simplicity of the original small block design, selected lighter materials such as aluminum and composites, opened it up to breathe more efficiently, and installed variations of this engine in much of their vast product line. The LS-series was born with rave reviews and fantastic success.

Renegade recognized the need to keep up with the latest technology, so in 2005, the 944 LS-series kit was introduced... and it's now our biggest seller. Then came the 911 LS-series kit, which has made quite an impact with the Porsche purists, boasting lighter weight than the 3.0L engines. Even some 914 LS-1's have been built with some amazing results. BUT, why hasn't the ultra smooth, very simple, and quite powerful LS-1 found a home in the 928? Well, it has now!!!

Introducing the LS-series automatic and five speed 928 conversion kits! ( picture ) I can tell you with confidence, this motor installation is actually quite easy and the results are fantastic. Plus, it's much lighter and smaller than the stock 928 engine making maintenance a breeze. With the extra-added room in the engine bay of the 928, several LS-series motors and their accessory packages will fit under the hood including the Corvette ZO-6. Even carbureted versions of the LS based motors are an option if cost and simplicity are paramount.

Maybe you like the idea of a carburetor but seek the weight savings of the all aluminum LS-1? Thanks to Edelbrock and MSD, they have teamed together to build an intake and ignition system for the LS-series. Edelbrock has developed an intake that will replace the composite unit and allows for the installation of a four-barrel carburetor. MSD have used their expertise to manufacture an ignition control system that uses the stock individual coil packs on the factory LS engines. Together, these clever creations eliminates the need for the GM computer or custom harness, and makes the Renegade LS-series 928 engine conversion even easier yet.

Our final option may indeed be the most popular. Renegade Hybrids and Turn Key Engine Supply have teamed up to develop a specific engine package for each of our new LS-series conversions including the 928. With a new engine (not rebuilt), equipped with a complete stand alone FI system, the computer already programmed, a harness already custom built, the proper accessories installed, the correct exhaust manifolds provided, dyno tuned to your desired HP, and backed by a iron-clad warranty, this option must be very expensive... right? No way. We have new 410HP motors ready to ship for under $8000 with our discount! Don't believe it, take a look: here
