Posted: Sat Mar 02, 2024 7:48 pm
The RX8 LS swap is a popular solution for RX8 owners facing engine failure, offering a new life to this common sports car. The RENESIS engine, while innovative, is known for its failure rate, leading many to consider swapping it out for a more reliable option. The LS engine, ubiquitous in the US, becomes a prime choice due to its availability, ease of sourcing, and the comprehensive swap kits available, making the process relatively straightforward compared to other engine swaps.
LS Engine Overview
LS Generation 3 (1997 – 2007): This generation introduced a clean sheet design, moving away from the aging LT engines to create a more compact, lightweight V8 with impressive power output. Popular engines from this generation include the LS1 and LS6, both offering significant power and torque.
LS Generation 4 (2005 – 2020): The Gen-4 LS engines introduced further refinements and innovations such as VVT and cylinder-shutoff technology. Notable engines include the LS2, LS3, and the mighty LS7 and LS9, each providing a range of power outputs suitable for various performance needs.
Choosing the Best LS Engine for an RX8 Swap
The choice of LS engine largely depends on individual budgets and performance goals. Common choices include the LS1 and LS2 due to their availability and the wealth of documentation on these swaps. Transmission choices, differential options, and the necessity of additional modifications (such as suspension and brakes upgrade) play a significant role in the swap process.
RX8 LS Swap Kits
Several aftermarket kits facilitate the RX8 LS swap, including offerings from V8Roadsters and LS1RX8. These kits aim to simplify the engine transplant process but may require further modifications or specific parts to complete the swap successfully.
Considerations for the RX8 LS Swap
Swapping an LS engine into an RX8 is not without its challenges. Key considerations include steering rack relocation, front sway bar spacers, the deletion of the stock power plant frame, custom propeller shafts, fuel pump upgrades, and the integration of the LSx headers and wiring harness. Additionally, relocating the battery to accommodate the larger LS engine and upgrading cooling, fans, A/C, and brakes to handle the increased power are essential steps in the swap process.
LS vs. RENESIS and Other Engine Swap Options
While swapping for another RENESIS engine is the simplest option, the appeal of a V8-powered RX8 lies in the LS engine's reliability and performance potential. Alternatives to the LS swap include engines like the Honda K-Series, Ford Mustang 5.0L Coyote, Subaru EJ Series, Nissan SR20DET, Toyota 2JZ-GTE, BMW S54, and the Mazda 20B-REW for those wanting to stick with a rotary engine.
In Conclusion
The RX8 LS swap offers a blend of performance, reliability, and a unique driving experience, making it a worthwhile project for those willing to invest the time and resources. Whether for performance, reliability, or the sheer joy of a V8 roar in an RX8, the LS swap remains a popular choice among enthusiasts.
