Thinking about upgrading or swapping out your engine? A crate engine might just be the ticket. These come fully assembled—honestly, it’s a relief not to have to build one from scratch. The key to buying the right crate engine is knowing which type fits your vehicle, performance needs, and budget. You’ll want to consider things…

When you’re building or upgrading an engine, rod ratio is one of those numbers you really can’t ignore. Rod ratio is the relationship between the length of the connecting rod and the stroke of the crankshaft, and it directly affects how your engine performs. This simple number influences power output, piston movement, and engine stress.…

When you install coilover suspension, corner balancing is a crucial step if you want your car to handle well. It means adjusting the weight on each wheel so the car feels balanced both side to side and front to back. Corner balancing improves your car’s stability and cornering by distributing weight more evenly across all…

Choosing wheel offset and width is a big deal if you want your car to handle at its best. Wheel offset is the distance between the wheel’s mounting surface and its centerline, and it affects how far the wheel sits inside or outside the wheel well. Width? That’s about how much tire meets the road,…

Advanced tuning with CAN bus data lets you tap into the detailed info flying between your car’s components. If you get how CAN bus data works, you can keep a close eye on engine and system settings—and tweak things with a lot less guesswork. This guide lays out the basics and shows how this data…

When you’re installing aftermarket wheels, knowing the right lug nut torque really matters for safety and performance. The correct torque usually falls between 85 and 150 foot-pounds, depending on your wheel and stud size. Most 14mm studs? They typically want about 150 ft-lbs. Using the wrong torque can lead to wheel damage, loose wheels, or…

When you’re dealing with open loop and closed loop systems, you’re basically picking how a process keeps itself in check. Open loop systems just follow preset instructions—no feedback, no second guessing. Closed loop systems, on the other hand, use feedback to adjust and (hopefully) improve their operation. Knowing the difference can save you some headaches…

Real-time engine monitoring lets you keep tabs on your engine’s health and performance in the moment. It’s a handy way to dodge expensive repairs and spot trouble before it gets serious. The best apps and hardware for real-time engine monitoring give you clear data on key engine metrics like temperature, RPM, and fuel use. There’s…

Installing a wideband sensor sounds pretty straightforward, but it’s easy to trip up. There are some mistakes that can throw off your readings or even wreck the sensor. One of the biggest errors is putting the sensor way too close or too far from the turbo or exhaust. That messes with how well it measures…

Building a track sim setup for testing tunes lets you fine-tune your car’s performance without ever stepping onto a real track. The real trick is to get a setup that mimics actual driving conditions closely enough, so you can spot changes fast and with confidence. This saves you time, money, and—if I’m honest—a bit of…

Turbo engines are notorious for pushing oil vapors and blow-by gases right into the intake system. That gunk can build up and drag down performance over time. A good oil catch can steps in to capture those oil vapors before they reach the intake. It keeps your engine cleaner and helps it run smoother and…

When you’re tackling an engine swap, building your own wiring harness is honestly one of those steps you can’t skip. A custom wiring harness ties your engine into the car’s electrical system, making sure everything talks to each other and works safely. Without a proper harness, the engine and vehicle just won’t communicate right—which can…

Choosing the right radiator fan setup is key to keeping your system cool and running smoothly. You want fans that balance good airflow with quiet operation, while fitting your radiator size and space. This means picking the right fan type, size, and placement to make sure heat gets pushed out efficiently. Knowing how many fans…

High-volume oil pumps are built to move more oil through your engine than standard pumps. This can improve lubrication, especially in high-performance or modified engines. The main benefit of a high-volume pump is that it helps ensure enough oil reaches critical parts of your engine faster. That means less wear and more reliability when you’re…

Electric vehicles deliver power in a way that feels totally different from traditional cars. You get maximum torque right from zero speed, which makes acceleration feel instant and strong. This comes down to how electric motors work. They use current to create torque, so when you press the accelerator, you get that immediate response. Combustion…
