Why Go RWD with Your Honda Civic EG?

So, why would anyone go through the trouble of converting a front-wheel-drive Honda Civic EG to rear-wheel-drive? It’s a valid question, and the reasons are as diverse as the car community itself. Primarily, it boils down to driving dynamics and performance potential. Front-wheel-drive cars, while excellent for daily driving, efficient packaging, and good traction off the line, have inherent limitations when it comes to performance driving, especially in terms of handling balance and driftability. In an FWD car, the front wheels are responsible for both steering and putting power down. This can lead to understeer (where the car pushes wide in a corner) as the front tires struggle to do both jobs effectively, especially under heavy acceleration. Converting to RWD fundamentally changes this equation. By sending power to the rear wheels, you separate the functions: the front wheels are now solely dedicated to steering, allowing for a much sharper and more responsive turn-in. The rear wheels handle the propulsion, enabling controlled oversteer and the ability to drift with finesse. For many, this is the holy grail of driving feel. Another massive draw is the potential for more powerful engine swaps. While the stock EG engines are great, the chassis is incredibly adaptable. Swapping in a larger, more powerful engine – especially one that's naturally RWD-biased (think Rotary, V8, or even a powerful Inline-6) – becomes much more feasible and mechanically sound when paired with a RWD drivetrain. The transmission tunnel and rear axle are designed to handle higher torque and power loads more effectively in a RWD setup. Furthermore, there's the sheer cool factor and uniqueness. A RWD EG is a rare sight. It stands out from the crowd, not just for its modified appearance but for its distinctive driving character. It’s a statement build that says you’re serious about performance and willing to go the extra mile. For dedicated track use and drifting, RWD offers superior control and predictability. While skilled drivers can certainly make an FWD car perform, a RWD setup generally provides a more neutral handling balance and makes it easier to manage the car's attitude mid-corner or during a slide. It allows for precise throttle control to adjust the car's angle, which is crucial in disciplines like drifting. Lastly, it’s a passion project. For many gearheads, the RWD conversion is the ultimate challenge. It’s a project that tests your skills, expands your knowledge, and results in a truly bespoke vehicle that reflects your dedication and hard work. The satisfaction of building something so unique and capable is a reward in itself. So, if you're looking for a car that's more engaging, offers higher performance ceilings, and stands out from the pack, a RWD Honda Civic EG might just be your dream machine.

The Nitty-Gritty: What's Involved in a RWD Conversion?

Alright guys, let's get down to the brass tacks. Converting a Honda Civic EG to rear-wheel-drive isn't exactly a walk in the park. It's a complex, multi-faceted project that requires a significant investment in terms of time, money, and mechanical expertise. You're essentially redesigning the car's core drivetrain layout. The most common and arguably most practical approach involves swapping in a complete RWD drivetrain from a donor vehicle. This usually means finding a rear-wheel-drive chassis that shares some mechanical similarities or can be adapted to fit. Think about platforms like the Nissan S-chassis (Silvia, 240SX), Mazda RX-7, or even some older Honda models that were RWD from the factory, though those are much rarer and harder to find. The core components you'll need to address are numerous and interconnected. First and foremost is the transmission and engine. You’ll need a compatible RWD transmission and, typically, an engine that's designed to work with it. This often means an engine swap goes hand-in-hand with the RWD conversion, as most powerful RWD engines aren't factory FWD. Next up is the rear axle and suspension. This is where things get really custom. You'll need to source a suitable RWD rear axle (differential, driveshafts, hubs) and figure out how to mount it securely and correctly within the EG's unibody. This often involves custom fabrication – cutting, welding, and reinforcing the chassis to accommodate the new suspension geometry and mounting points. You'll likely need to fabricate custom control arms, trailing arms, and shock mounts to achieve proper alignment and suspension travel. The driveshaft is another critical piece. You'll need a custom-made driveshaft that connects the transmission's output flange to the rear differential's input flange, ensuring the correct length, diameter, and phasing to prevent vibrations. Fuel system modifications are also essential. You'll need to reroute fuel lines, install a new fuel tank (often a fuel cell for safety and space), and potentially upgrade the fuel pump to handle the demands of a new engine. Braking system upgrades are non-negotiable. With increased power and different weight distribution, your stock brakes won't cut it. You’ll likely need to upgrade to larger calipers, rotors, and potentially a brake proportioning valve to balance the front and rear braking forces. Steering components might also need modification to work seamlessly with the new front suspension geometry or engine placement. Electrical systems are a whole other can of worms. You'll need to wire in the new engine's ECU, dashboard instruments, lighting, and potentially power steering if the new engine requires it. This often involves custom wiring harnesses or adapting existing ones. The transmission tunnel will almost certainly need modification – cutting and reshaping – to accommodate the RWD transmission's shifter and driveshaft. Custom engine and transmission mounts are mandatory to securely hold the new powerplant in place and ensure proper alignment. Finally, driveshaft loops are highly recommended for safety, especially in high-powered applications, to prevent catastrophic failure if the driveshaft breaks. It’s a massive undertaking, and many opt to have professionals handle the fabrication and major assembly, but understanding the scope is key.

Essential Components for Your RWD EG Build

Alright, let's talk parts, because you can't build a killer RWD Honda Civic EG without the right gear. This isn't a weekend warrior list; we're talking about the core components that make a RWD conversion possible. Think of this as your shopping list for transforming your FWD EG into a drift-ready or track-hugging machine. First up, the heart of the operation: the engine and transmission. You’ll need a robust RWD engine and a gearbox that can handle the power. Popular choices often include engines from Nissan (like the SR20DET), Mazda (Rotary 13B-REW), or even some Toyota powerplants. Whichever you choose, make sure it comes with its corresponding RWD transmission. Next, the rear end. This is crucial. You'll need a complete rear subframe or axle assembly from a RWD donor car. This includes the differential, driveshafts, hubs, and potentially the trailing arms and control arms depending on the suspension design. Nissan S-chassis rear ends are common swaps due to their availability and robustness. Custom driveshaft is a must-have. Since you're marrying a transmission from one car (or a specific model) to a differential from another, the stock driveshaft won't fit. You'll need to get a custom one fabricated with the correct length and U-joint configurations. Fabricated mounts are non-negotiable. This includes custom engine mounts, transmission mounts, and rear differential mounts. These need to be designed and welded precisely to ensure proper alignment, prevent vibration, and handle the stresses of spirited driving. Fuel system upgrades are vital. This often means a new fuel tank or fuel cell, which might require modifying the rear of the chassis or trunk. You'll also need upgraded fuel lines and a high-performance fuel pump to feed your new, likely more powerful, engine. Braking system components are a safety and performance essential. We're talking upgraded front and rear brake kits. This could include larger rotors, multi-piston calipers, and performance brake pads. You might also need a brake proportioning valve to fine-tune the balance between front and rear braking. Cooling system components are also critical, especially if you're going with a more powerful engine. This means a larger, high-performance radiator, suitable hoses, and potentially an oil cooler and power steering cooler. Steering components might require attention. Depending on the engine and suspension setup, you might need to modify or replace steering rack components, tie rods, or power steering lines to ensure proper geometry and feel. Custom exhaust system is pretty much a given. You'll need an exhaust that clears the new drivetrain components and runs efficiently from your chosen engine all the way back. Wiring harness and ECU are essential for getting the new engine to run. You'll likely need a standalone ECU or a conversion harness to integrate the new engine's electronics with your car's basic functions. Chassis reinforcement is highly recommended, especially in the areas where the rear subframe mounts. Welding in reinforcement plates or gussets will significantly improve the chassis's rigidity and prevent potential stress-related failures. Finally, don't forget wheels and tires. You'll need RWD-appropriate wheels with the correct bolt pattern and offset, and tires that can put the power down effectively and handle the new driving dynamics. This is a significant investment, so plan wisely and prioritize quality parts.

The Driving Experience: What to Expect

So, you've gone through the painstaking process of converting your Honda Civic EG to rear-wheel-drive, swapping in a new engine, fabricating mounts, and wrestling with custom driveshafts. What's the payoff? The driving experience is, in a word, transformative. It's a completely different animal compared to its stock FWD counterpart. The most immediate and profound change you'll notice is the handling balance. Gone is the inherent understeer that plagues most FWD cars under power. Instead, you'll experience a much more neutral feel. The steering becomes sharper, more direct, and you'll feel a distinct separation of duties: the front wheels turn, and the rear wheels push. This allows for significantly improved turn-in response, making the car feel more agile and eager to change direction. Oversteer becomes a controllable entity. With power going to the rear wheels, you can now use the throttle to adjust the car's attitude mid-corner. A little tap of the gas can initiate a gentle rotation, or a more aggressive application can result in a glorious, controlled drift. This opens up a whole new world of driving techniques and makes the car incredibly fun on a track or a closed course. The connection to the road is amplified. You'll feel more feedback through the steering wheel and the chassis, giving you a better sense of what the car is doing beneath you. This increased feedback allows for more precise inputs and a deeper engagement with the driving experience. Engine swap impact is huge. Since most RWD conversions involve an engine swap, the power delivery and sound will be drastically different. Whether you've opted for a high-revving rotary, a torquey V8, or a potent turbocharged inline-four, the experience will be elevated. The sound alone can be a massive part of the thrill. It requires a different driving technique. You can't just stomp on the gas and expect it to go straight like in an FWD car. You'll need to learn how to manage throttle application, especially when cornering, to maintain traction and control. This learning curve is part of the fun and makes mastering the car incredibly rewarding. Daily drivability can be compromised. While a RWD EG can be a blast, it's important to set realistic expectations for daily driving. Depending on the suspension setup, exhaust loudness, and overall tune, it might be less comfortable for commuting. NVH (Noise, Vibration, and Harshness) can increase significantly due to the custom drivetrain components. Maintenance becomes more involved. With a more complex RWD setup, especially if it involves a swapped engine, your maintenance routine will be more demanding. You'll need to be comfortable with a wider range of mechanical tasks. It's a head-turner. Beyond the driving dynamics, a RWD EG is a unique spectacle. It draws attention not just for its classic EG looks but for the inherent statement it makes about the owner's passion and dedication to creating something truly special. In essence, the RWD Honda Civic EG conversion delivers a raw, engaging, and immensely rewarding driving experience that is unlike anything you'll find in a stock FWD car. It's a project for the true enthusiast who seeks ultimate control, performance, and a unique connection to their machine.
