What happens when Nissan’s Juke six-speed has gearing that’s too short, the Sentra Spec V has gearing that’s too long down low, and the newer Sentra transmission doesn’t have the…

We’re back with Project EP3! This time we’re tackling one of the biggest weaknesses of our Honda Civic Si: its drivetrain. If you liked the video, please subscribe to our…

Can you really make serious power with a Subaru STI while keeping it 100% California smog legal? In this installment of our CARB-legal STI build, we install Cobb’s front-mount intercooler…

The Nissan MR20 was never designed to make three times its stock horsepower — so we’re fixing the weak points. Our original turbo MR20 was built for Nissan’s B18 Sentra…

MotoIQ tests Swift Springs back-to-back against another well-known spring brand on the same coilovers, at the same spring rate and ride height. Mike explains why Swift Springs have performed differently…

Choosing the most aggressive clutch you can find isn’t necessarily an upgrade. In fact, for most street cars, it can make the car harder to drive, put more shock into…

In this video we take a detailed look at a purpose-built street car that combines real aerodynamic function with everyday drivability. We cover splitters, end plates, hood vents, ducting, side…

In this video, we take a technical walkaround of Project Jeep and explain the thinking behind the build. We cover the suspension, steering, drivetrain, cooling, electrical system, armor, recovery gear,…

This video focuses on building a more capable street/track suspension package for the Toyota GR Corolla, emphasizing adjustability over simply installing stiffer parts. Mike explains why sway bars are one…

The Lancia Fulvia might be one of the strangest—and smartest—engine designs ever put into a rally car. In this video, Dave Coleman walks us through the incredibly unique narrow-angle V4…

The GR Corolla comes with solid factory brakes, but we quickly found some weak points: excessive brake dust, fast rotor wear, and inconsistent pedal feel under heat. So we upgraded…

We take a deep dive into the suspension system for our Project GR Corolla with Grant from Annex Suspension. This isn’t just another coilover kit—this is a motorsport-grade, 3-way adjustable…

Building a 1,000 horsepower VR38DETT is easier than most people think—but doing it reliably is where the real engineering comes in. In this video, we break down how to build…

In this video we dyno test a 50-state legal Subaru STI using a full COBB Tuning bolt-on setup and off-the-shelf tune. This car uses all CARB-approved parts with EO numbers,…

A customer brought us a brand-new Bronco that had over $70,000 poured into a custom off-road suspension build by a “reputable” shop… but something didn’t feel right. What we found…

In this video we break down the complete build of a 1,000 horsepower Honda F22C1 engine for the Evasive Motorsports Time Attack S2000. This isn’t a drag build—it’s designed to…

We kick off Project GR Corolla by improving one of the most important foundations of performance: chassis stiffness. Even though the GR Corolla is already a stiff car from the…

The FL5 Civic Type R is one of the best performance cars on the market—but like many modern turbocharged engines, oil temperature control is critical for reliability and performance. In…

In this episode, Mike breaks down one of the most overlooked upgrades in the performance world: bushings. From alignment stability to wheel hop, torque steer, camber loss, and suspension bind,…

In this episode, we give you a deep technical walkthrough of our INFINITI QX80 R-Spec SEMA build — a fully functional, VR38-powered project created entirely in-house with help from some…

We’re putting together one of the coolest versions of Toyota’s legendary 4AG — a stroker 5AG hybrid with a billet MRP crank, JE pistons, and a ton of detail work.…

A Miata should handle great… but this one didn’t. My daughter’s Lucky Dog endurance racing Miata was nearly undriveable, thanks to cheap coilovers, mismatched sway bars, and worn bushings. In…

Welcome to Podcast #5 (even though we called it 4 in the video)! This week we’re joined by a very special guest: Dave Coleman—journalist, racer, engineer, and now Mazda’s Manager…
