MotoIQ Project Honda Ruckus

Project Honda Ruckus Part 6: The Final Option, Tuning the Transmission

By Jeff Naeyaert

In our last installment of Project Ruckus we got our super motor tuned and running well, however although our acceleration was vastly improved, we did not see much of an improvement in top speed, only gaining about 3 mph before hitting the 10.500 rpm rev limit. To make matters worse, our Ruckus is now always topped out on the rev limiter. Doubling our power has enabled our bike to zoom right on up to its top speed but once that speed is reached, the engine is screaming at 10,500 rpm continuously. This probably is not the best bet for long life!

Ask Sarah-Hey Sarah, what did the cost of all the Phase 3 mods on project Ruckus cost?

By Sarah Forst

If bling isn’t your thing, you can skip some of the pretty stuff and save about $600 but to get to the 50mph, open your wallet. READ ON...

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.

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.

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.

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.

The Best-Engineered Cars of LeMons

By Dave Coleman

The 24 Hours of LeMons is recognized as many things. Incredibly stupid. Safer than OxyContin. A flagrant waste of natural resources. Yes, yes, and yes, but to us, it is also a festival of junkyard engineering. Ever wondered how a Geo Metro would perform with a CBR 900 engine? Ever wondered if you could build a mid-engine, 8-cylinder Can-Am car out of a couple of Vanagons? Ever fantasized about building a mid-engine racecar out of a 1971 Honda Z600, a first-gen RX-7 and a Motorcycle? All this can be found at LeMons, and all of it deserves a closer look.

Frankenmiata freebuilding the engine

Freebuilding The Engine

by Dave Coleman

The engine used in this project was freebuilt from no less than four junk engines. Freebuilding is like rebuilding, but without all the stuff that costs money. Ignore all your instincts to think long term, and focus only on what is absolutely necessary to make the engine perform the task at hand -- surviving 14 hours of abuse before exploding. Labor cost, it should be noted, is not considered in LeMons accounting, a fact that can lead to countless lost weekends and the absolute destruction of any social life. You have been warned.

Frankenmiata turbocharging

How to Turbocharge a Miata for less than $100

by Dave Coleman

After a few timid part-throttle passes listening for detonation, we finally buried the pedal and watched in horror as our little creation ripped off 170 hp on 7 psi of boost, pegging the 100-psi fuel pressure gauge in the process. Shock, horror, giddy satisfaction and abject terror had a bus fight on the way to our heads. Abject terror won the fight. There was no way the car would survive 14 hours of racing at this power level. It would overheat, throw a rod, melt a piston, ping its ring lands into oblivion, and overheat some more. Then the fuel lines would explode and we'd all burn to death. We immediately started trying to figure out how to make less boost.

And on the 8th Day... Falken Tire's S13 Drift Monster

By Mike Kojima

This is a story of teamwork and determination that began with a Bang.  During the morning practice before the top 32 elimination at the 5th Seattle Round of the Formula D Professional Drift Series, Dai Yoshihara had a serious accident that destroyed the Falken/Discount Tire Lexus IS350 that was featured by us just a few weeks ago. The accident struck a serious blow to Team Falken as the Lexus had just come to a point in its development where it was a force to be reckoned with in Dai’s hands.  With high qualifications in Las Vegas and Seattle, it seemed just a matter of time before Dai and the Lexus would sit on the podium.

Project EVO X: Part 1 - Suspension

By Mike Kojima

What does the guy that has the Ultimate Streetcar do for a daily driver?  Cheston Chiu is no stranger to building some really sick iron.  His super clean, built to the hilt twin turbo 350Z is no show car.  The Z placed second, missing first place by less than a point in Sport Compact Car Magazine’s Ultimate Street Car Contest and repeated the performance when the USCC torch was handed to Modified Magazine after SCC’s demise. Since the Z is a bit extreme to be a daily driver, Cheston wanted something nice but not as boring as his Maxima beater.  The car still had to have some potential for some nice modifications but nothing that would render the car impractical as a daily driver.  After considering several different options, Cheston settled on a 2010 Mitsubishi EVO X.  The biggest reason was the twin clutch TC-SST transmission.
