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.

A Look Inside Dai Yoshihara’s Team Falken Pro Drift Machine

By Mike Kojima

A comment from one of my road racing friends prompted me to write this article. He said as a snide remark "I heard you are now involved with drifting, too bad those are not real race cars". No amount of arguing could convince him that a typical pro drift car is a sophisticated machine, one several times more massaged and engineered than his own race car.  So lets take a look inside Dai Yoshihara's Lexus IS350 that he drives for Team Falken and Discount Tire on the Formula D Circuit.

Project NSX: Part 2 - Tuning a Limited Slip Differential; Tricks of the Pros

By Mike Kojima and Billy Johnson

By nature a differential wants to send all of the engines power to the wheel with the least amount of traction, the path of least resistance. The side effect of this is unwanted inside wheel-spin out of corners, and even single wheel spin on straight-aways (aka: peg-legging, one-tire-fire, etc…). This greatly affects acceleration since the power is not able to be put to the ground efficiently and is lost through the inside unloaded tire.

Demolition Derby Tech part 2 The Science Behind the Horror

By Mike Kojima and Aaron Guardado

After we prepared two cars as seen in part one of this series. We proceeded to enter them in a destruction derby, the infamous Orange Crush event at the Orange County fair. We faired ok, making it through most of the event with only minor injuries despite the car’s taking some enormous punishment.

By Mike Kojima

When we last left project EVO IX we had just tried out the most basic bolt on mods and ended up being pretty pleased with the results, picking up nearly 30 whp from stock with just a few hours of work including dyno time. Drivability was improved as well making our experience a win win situation.

Inside the X-games fiesta lead art

Inside the 800-hp X-Games Fiestas - Update 1

By Dave Coleman

An American rallycross is an autocross in the dirt. A European rallycross is an explosion of rally bundled up and barely confined within the grounds of a racetrack. Roughly speaking, take every european rally car that has ever been banned for being too fast, turn up the boost, and then run 6 of them, wheel-to-wheel, in a sprint race that alternates between pavement and dirt. When a team of Swedish rallycross fiestas crossed the pond to run Pikes Peak and the X-Games I wanted to know more. How exactly do they get these Miata engines (the Ford Duratec is also known as a Mazda MZR) to 800-hp, and how do they harness that power and make it usable? This story is everything I know, updated frequently as I learn more...

Skunk2 Mitsubishi EVO VII-IX Composite Fuel Rail

Skunk2 Mitsubishi EVO VII-IX Composite Fuel Rail

Motoiq Staff Report

The first ever composite fuel rail for Mitsubishi’s Evo VII-IX is here. Skunk2’s Composite Fuel Rails are made using a proprietary carbon-impregnated, aerospace thermo-polymer composite—a material that’s 33-percent lighter and 60-percent stronger than aluminum.  Skunk2's composite material insulates fuel from both radiant and conductive heat transfer underneath the hood, resulting in more horsepower and torque.  The composite material has ultra low thermo conductivity so underhood heat is not transfered to the fuel resulting in fuel temps up to 100-degrees F cooler when compared to aluminum.  This results in denser fuel and greatly reduces the chances of vapor lock, crfitical when volitile running fuels with a high alcohol content.

Project Rally Beater Return to Glory

Project Rally Beater -- Return to GLORY

(or return to rallying an old piece of crap, at least...)

By Dave Coleman

It only took one turn for all my doubts to disappear. It had been four and a half years since the Rally beater last turned a wheel in anger and I was, only moments earlier, quite skeptical that it could still do it. When I dropped the hammer at the start of stage 1, I still had no idea if the car would work. After all that time parked in your driveway, nothing you can do on the pavement will tell you if your old box still handles well in the dirt or if you still remember how to drive it. But as the SR20 wailed and the gravel flew, the beater's normally rough, clattery ride smoothed out into a gloriously fluid set of arcs, slides, and various maneuvers named after old Scandinavians. I had almost enough time to start giggling with boyish glee before the engine turned off.

Project Silvia lead JIC Strut story

Project Nissan S13 Silvia: How to Polish Your Tube
(or What to do When Your JIC Struts Dry Up)

By Dave Coleman

Engineering a car is a series of compromises. When Nissan decided to make the 240SX a slow, soft piece of suck, it was a compromise calculated to make it durable, quiet, easy to drive every day, and cheap to build. When I decided to take this same worn-out, 300,000-mile piece of suck and make it fast, I was naturally sacrificing some of that comfort and undoubtedly some durability.

G-Spec Nissan 370Z brake line Infiniti G37

G-Spec Braided Steel Brake Lines for the Nissan 370Z Rock!

By Mike Kojima

We recently evaluated a set of G-Spec lines for the Nissan 370Z.  The G-Spec lines also fit the Infiniti G37 Sedan and Coupe. We installed them on the Killer B which is starting to become our official 370Z Project demonstrator vehicle.  The Killer Bee is a Sport Package 370Z with the standard factory big brakes.  Although the Sport Package 370Z has exceptional brakes, some improvement can usually be found by installing braided steel lines.  This is because stiff braided steel lines do not expand with pressure like the stock rubber lines

How to Make Your Own Effective Exhaust System

By Mike Kojima and Sarah Forst

You are bummed.  You don’t own a Honda, STi, EVO or some sort of popular sport compact car.  Maybe you have an old school Celica, Corolla, Cavalier, Neon, Hyndai, Geo, Saturn or a similar ride that does not have tons of aftermarket support.  Maybe you want a spiffy all polished stainless system but can’t get a pre-made offering that you like.  Maybe you do have a popular car but it has a ripping turbo system and no one makes a good pre made 3” system for your car.  What to do?  Well we will show you how to roll your own system that will be as good as, maybe even better than a commercially made system, probably for less money as well!

Project Low Buck Nissan SR20DE Part 2

By Mike Kojima

In our last edition of Project Low Buck SR20DE, we stated our goals to obtain a decent amount of naturally aspirated horsepower and good track day drivable reliability from an underdog plain jane SR20DE without braking the bank. Fulfilling these goals would also create an engine with excellent street driving characteristics as well. All of our engine work will be done on the cheap with a tight budget in mind but with plenty of attention paid to minor details that can really help an engine live under the stress of track day pounding, perhaps the most abusive environment that a grass roots enthusiast will subject his engine to.
