The Toyota GR86 is an exceptional case, having endured 17,000 miles of track driving without any major issues. However, when its original engine developed problems, the owner was forced to swap it out for a new one. This remarkable story raises questions about the reliability and durability of sports cars designed for track use.
The GR86's engine, originally sourced from Subaru, was replaced by a Honda K-Series inline-four from MA-Motorsports after its harmonic balancer broke off, causing damage to the crankshaft and bearings. The new engine was installed using a KPower Industries kit, which included an adapter that allowed it to connect to the stock six-speed manual transmission.
The K-Series is a popular engine swap choice due to its ubiquity, compact dimensions, and headroom for upgrades. This particular engine was used in the first-generation Acura TSX, producing around 200 horsepower from the factory. With the addition of a Link G4X XtremeECU, the swapped engine now boasts an impressive 240 hp.
The GR86 itself has also undergone significant modifications for track duty, featuring aftermarket coilovers and upgraded brakes with AP Racing calipers in front and Brembo calipers in back. The interior has been gutted to accommodate a Momo steering wheel, OMP driver's seat, and a custom aluminum dashboard housing a Link/AIM digital display.
However, this engine swap raises concerns about the reliability of sports cars designed for track use. While the GR86 is well-suited for its intended purpose, problems like oil starvation due to gasket failure have been reported by other owners. These issues may be covered under warranty, but getting the automaker to make good on that promise can be a challenge.
The extensive modifications made to this car may have voided the warranty, at least in part. This is a concern for owners who may not fully understand the implications of such modifications. As a result, it's essential to carefully consider the potential consequences before making any significant changes to your vehicle.
Despite these issues, the GR86 remains an attractive option for those seeking a simple and relatively affordable sports car. With the replacement engine potentially evolving into something different, this may not be the case for long. The use of aftermarket engine swaps can void a vehicle's warranty, highlighting the importance of understanding the implications of such modifications.
It's worth noting that other reports have surfaced of GR86 engines failing after track use, but for different reasons. These incidents serve as a reminder to always prioritize proper maintenance and care when pushing your vehicle to its limits.
Ultimately, the Toyota GR86 engine failure story serves as a cautionary tale for car enthusiasts who may be tempted to push their vehicles beyond their intended capabilities.
The use of aftermarket engine swaps can void a vehicle's warranty, highlighting the importance of understanding the implications of such modifications.
