928 LS V-8 Automatic and Five Speed Conversion

Since the late 70’s when the 928 was introduced, many have called it the “German Corvette.” In almost every way, it outperformed Corvette’s for 20 years since its birthday. Unfortunately, the power under the hood was one thing that did not live up to the nick-name. So why not install a Chevy V8 and give it the boost in power and reliability it’s been begging for?

I can tell you with confidence, the all aluminum LS V8 engine installation using the Renegade Hybrids conversion kit, is actually quite easy…and the results are fantastic. Plus, it's much lighter and smaller than the stock 928 engine which improves the handling and it makes 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 in the 928 engine bay including the Corvette LS-7. Even carbureted versions of the LS based motors are an option if cost and simplicity are paramount.

On the subject of engines, any new or used LS series GM V-8 will do wonderfully. Some minor modifications may be necessary, but you are welcome to call us for more specifics. If you are looking for our highest recommendation for a donor engine, Custom Built Motors has a program tailored for the Renegade Hybrids 928 customer.
