Cayman All Aluminum LS Series V-8 Conversion
Basic kits fr4om 4,995.00! Scroll down for details!

With the huge success of our later model 911 (996/997) and Boxster S kits, and continued engine failures in virtually all of the later model cars, Renegade now offers a GM LS series V-8 kit for the Cayman! Yes, it fits! Imagine the sensational styling of the Cayman, the power of a Corvette, the drive-ability of an ‘econo-box’, and the handling of…well…a Cayman!

Critics, Purists and Enthusiasts agree, the Renegade Hybrids Cayman V-8 conversion just makes perfect sense. Why? Let's look at the facts together:

The flat-6 engine from the Cayman, and an LS series all aluminum V-8, weigh almost the same. The Cayman produced horsepower in the mid to high 200's, yet a new, entry-level GM LS-3 engine, starts in the mid 400's which is higher horse power than a twin turbo! The twin-turbo factory engine weighs 200lbs. MORE than the LS, is very difficult to install in the Cayman, and costs 3 times as much! The stock cooling system found in the Cayman will support the V-8 using our conversion kit! The stock fuel system found in the Cayman will support the V-8 using our conversion parts! The gauges can be converted to work with your V-8. Both the power steering and water pump are now electric increasing HP and efficiency! $19 oil changes and there is ample room to service the engine! Smog legal options are available for these engines while still providing enhanced performance and much greater reliability!

To increase strength, dependability, and performance, we have designed the Cayman kit around a Boxster S transaxle. The Cayman transaxle was engineered lighter with physically smaller gears and shafts, and the ratios were very short, which is not favorable or strong enough for the V-8. The Boxster S transaxle has repeatedly taken abuse over 600HP in our Boxsters, 914’s, & kit cars, and we have yet to see one fail. Even the gear ratios and optional upgrades are quite favorable to the V-8 conversion using the Boxster S 6-speed transaxle. We understand that this means you will need to source a good used Boxster S tranny from a salvage yard, but your Cayman transaxle has value equivalent to the Boxster S in many cases.

When installing the V-8, there are some modifications to the fire wall. This will likely reduce your seat travel by just one click. However, aftermarket performance seats are often thinner in the back to reduce weight and improve torso stability. You will not likely need that last 1/2 inch after you install better seats. The completed project looks stock, handles the same, and functions as intended, but the power and reliability are much greater without sacrifice. Why settle for the same performance at a premium with little guarantee on reliability, when you can make the smart and exciting move to the Renegade LS V-8 conversion! Below is the conversion kit and some options that are available to help assist you in completion of your project. If you have any additional questions, please give us a call or email:
