Clutch Tech Part One: The Pressure Plate, Get a Grip!

By Mike Kojima

Ever wonder what is perhaps the second most important thing that makes your car move? You probably guessed that the engine is the most important thing. The clutch is the second part of the equation, the part that couples the engine to the ground. Although it is the most critical component in your drivetrain, most enthusiasts have very little idea of how a clutch works, what are important attributes when selecting a clutch and how to pick the right clutch for their application. The right choice will get you moving and keep you moving reliably. The wrong choice may destroy itself, quickly wear out, not work according to your expectations and worse yet, break other parts on your car.


Project Aprilia SR50: 100 mpg Madness Part 1, Basic Bolt on Stuff

By Mike Kojima

Our new two wheel project is a very unique machine; it is an Aprilia SR50, perhaps the highest tech scooter on the market. It uses a full of tech, Orbital engine to combine the compactness and power of a two stroke engine with the fuel economy and low emissions of a tiny four stroke. The Aprilia engine uses licensed Orbital technology which is basically An ECU controlled, directly injected, stratified charge two stroke. Two strokes by nature produce pretty low NOX emissions due to their low operating cylinder pressures but are terrible for hydrocarbons as they tend to blow raw fuel out the exhaust port on overlap.

MotoIQ's Project Mitsubishi EVO IX

Project EVO IX: Part 4, In search of the Ultimate EVO Brake System

By Mike Kojima

How do you improve on something that is really good to begin with? The Evo is blessed with one of the best standard equipment brake systems found on any production car. In stock form the Evo has big Brembo 4 piston front and two piston rear brakes and big ventilated rotors on all 4 corners. With the normal brake modifications such as high temperature fluid, braided lines and upgraded brake pads, the stock brakes can handle just about any situation you would likely find on the street, including spirited driving in the twisties. With an aggressive high temperature brake pad, the stock brakes can also handle abusive track duty, even with R-Compound tires. The stock brakes even look good. No wonder many Evo tuners overlook the brakes when building fast Evos.


Revenge of the Nerd: Green, My Ass is Green

By Mike Kojima

One of the things that pisses me off to no end is misdirected members of the green movement. At a recent party I was cornered by one of the guests, a eco hippie hemp wearing type who accused me of pillaging the environment due to my penchant for high performance cars and the fact that I own quite a few of them. She ranted on about how GM killed the electric car, and other conspiracy theories that this type of person seems to always prescribe to. She proudly alluded that she drove a "super efficient" 30 year old VW bus to prevent from contributing to the self-serving industrial political machine, plus recycling an old vehicle reduced her "carbon footprint". Note to reader, this person also makes her own soap from old cooking fat, hardly flushes the toilet in her house and has a smelly compost pile in her back yard. She does bath and shave her pits though.


Robispec Badass 370z street class time attack car

Robispec’s Street Class Time Attack Nissan 370Z, Simple is Better?

By Mike Kojima, photos by Jeff Naeyaert

Robispec is a Southern California tuning shop whose specialty is a rather unusual one. Instead of the typical shop in search of speed via the quest for more and more power, Robispec’s game is increasing lateral G’s, of the cornering kind. The proprietor of Robispec is Robert Fuller or Robi, one of our favorite people. Robi is always willing to lend a hand or give advice to whatever project we have asked him, either formally as in our Project EVO IX or by helping us swing wrenches at the track. Robi is on our short list of people we call for help if we have a problem that needs solving.

About six weeks ago we got a call from Robi telling us he would have something special, a Nissan 370Z he was building for the SEMA show and the annual Source Interlink Super Lap Battle. As there has been a lack of serious Nissan 370Z parts development due probably to its sluggish sales, we eagerly awaited checking out what Robi could cook up in short order.

In the previous installment of Project Honda Ruckus, we worked with Dan Paramore of DPR racing to go where no one else had gone before by carefully porting the head of the Honda GET engine to maximize flow, improve combustion and raise the compression ratio.  To follow the progress of Project Ruckus, click here!


Dai Yoshihara's GT Channel Nissan 350Z time attack car

Dai Yoshihara’s Two Week Wonder, GT Channel’s Time Attack Nissan 350Z

By Mike Kojima

Pro Drifter and Formula D ace Dai Yoshihara is used to working on tight deadlines. Perhaps you have read our story on his 8 day wonder S13 that we covered in detail. To tell this story, and appreciate it, you have to rewind to a week before the 2009 SEMA show. Dai got the request from his long time supporters, The GT Channel to build one of their show cars into a time attack car for Source Interlink's 2009 Super Lap Battle Finals. The folks at the GT channel had a Nissan 350Z roadster that had been originally built as a SEMA show car two years ago, it had been gathering dust and the GT Channel wanted to do something with it. Dai was contacted and a deal was struck to give him the car to build into a time attack car.

The Best-Engineered Cars of Lemons
#2: The MetroGnome (now availbale in rear-drive)

by Dave Coleman

When rumors of a rear-drive CBR-1000-powered MetroGnome surfaced, we immediately assumed Alex had turned his clever streak from junkyard engineering to misinformation and rumormongering. Well played, we thought... We gave him too much credit. The rumors were true. MetroGnome 2.0 does it from the rear.

MotoIQ at SEMA 2009

By Sarah Forst

No other city in the United States besides Las Vegas could possibly host the SEMA (Specialty Equipment Manufacturer's Association) show without being upstaged.  This amusement park for autophiles displays some of the most extreme car builds and aftermarket products.  Crazy concepts surround attendees at every direction.


KW Motorsports 3-way adjustable dampers for Nissan Sentra Spec-V

No Respect, Project Nissan Sentra Spec-V part 3, Building a Race Ready Suspension System

By Mike Kojima

There are 5 elements that have to work well in a successful time attack car. In order to win, a car has to have lots of power, lots of aerodynamic downforce with minimal drag, good suspension, anchor-like brakes and sticky tires. Of these 5, suspension is the most important system for a winning time attack car. Getting the best possible handling is more important than eeking out every last bit of power from the engine. Without good suspension you cannot get the most out of the tires, brakes, aero or engine.
