Cusco EVO Twin Disc Clutch

Project EVO VIII part 4, Getting More Trackside Grip, Killing Some Slip

By Mike Kojima

After enjoying driving our much-improved EVO VIII for a few months we were again motivated into another round of mods by the need to fix a necessity, a slipping clutch.  We also wanted to improve our suspension for more aggressive driving.

MotoIQ Project Honda S2000 S2K

Project S2000 Part One, Wheels and Tires

By Khiem Dinh, photos by Jeff Naeyaert

The Honda S2000 or S2K as it is affectionately known is one of our favorite cars from one of our favorite brands, Honda. Its most endearing feature is its front engine rear drive chassis with a front mid engine configuration giving an ideal 50/50 weight distribution.  Although the S2K has a bad reputation as being a twitchy, hard to handle car, we have found, that with the proper modifications, it is just the opposite, a sweetheart that is easy for a reasonably skilled driver to flat out haul ass in that is nearly impossible to make understeer.

RC engineering 1000cc injectors for EVO 4G63

Ask Sarah- How to fix your EVO

By Sarah Forst

First, repeat after me- you can’t go reliably fast if your wallet is on a diet!  Although you haven’t given me enough information to properly answer your question as I don't know what other parts are on your car, I will give it a guess assuming you are not spending much money on your 4G63 to begin with. Your current setup includes too small a turbo and probably too undersized a fuel system for those boost levels.  Let’s start with the stock turbo on the Evo VII.

Nissan QR25DE Engine Turbo by Jim Wolf Technology

Jim Wolf Technology's Turbo Nissan QR25DE Powerhouse - Part 1

By Mike Kojima

Compared to the late great SR engine family, the early Nissan QR25DE has a spotted history as a performance engine.  In the performance world it has earned a reputation for being fragile and the many recalls that Nissan has had for serious problems from blowing head gaskets to blowing rods out the side of the block has furthered this reputation.  The engine's redeeming features are a cylinder head that flows extremely well, a light overall weight and a strongly supported crank and lower end. A fragile engine is not going to work for our time attack Spec-V so we are going to address the engine’s weak points and see if we can turn the QR into a solid performer capable of racing levels of performance and reliability.

Project Toyota Tundra Part One, TRD Suspension and Brakes

By Mike Kojima

Since we are all about worry free towing, we decided to look into getting a new full size truck.  Over the years we have used about every truck on the market including the Dodge Ram and Ford F250 SD (which was our current favorite truck).  Dan Gardner, owner of our Project Scion racecar was awfully impressed with the Tundra he received on long-term loan from Toyota and recommended we give one a try.

Clutch Technology Part Two, The Clutch Disc Friction Material

By Mike Kojima

In our first segment on clutch technology we discussed the pressure plate and how it works.  However the pressure plate is only half of the equation when it comes to clutches and how they work.  We cannot ignore the all important disc. The clutch disc is such a simple device, yet it has a significant responsibility, the responsibly of transferring the engine’s torque to the ground. It also controls most of the clutch’s driveability characteristics. A disc can be the difference between a clutch that is grabby, chattery and nearly impossible to drive on the street to one that is butter smooth. The disc can also make all the difference between a clutch that slips and burns up when the boost is turned up or the nitrous hit, to one that grabs and holds the power.

The Ultimate Guide to Suspension and Handling Part I: Wheels and Tires

by Mike Kojima

Here is a Flashback Friday article to the beginning of our Ultimate Guide to Suspension and Handling. This long running (10 parts and counting) series has everything you need to make your car handle.

Horsepower is sexy and chicks dig it, at least a lot of meatheads think that way. Making horsepower is relatively easy. A lot of competent people know how to make power, lots of it. Until drifting became the rage in this country, handling and cornering prowess was for geeks, the road racing elite and autocrossers. Handling was for dweebs that raced around cones in parking lots, or loners prowling canyon roads at night, not for cool people in the scene.

EFI 101, Basic 4-Cycle Engine & ECU Operation and Tuning Rhetoric

by Christian Krahenbuhl

Automotive engineering involves a series of compromises. The compromise of designing affordable, durable, and fuel efficient engines that are enjoyable to drive while meeting modern emissions regulations has made the job of EFI controls very complex. Afford-ability and durability are concerns because manufacturers and consumers have limited resources. An engine designed to use some super metal like unobtainium (Uo and atomic number of 666) would be ideal.

Ask Sarah

By Sarah Forst

I know back pressure is bad. Everything I remember about high school physics and everything I read over the years from SCC and Honda Tuning tells me back pressure is bad. I made that statement the other night at the pub to a friend. I found myself trying to make the argument without any scientific facts. He drives a 5 year old Mustang GT and claims he needs back pressure for his engine to work. He claims to have dynoed it with open headers and it lost power.

MotoIQ Project Aprilia SR50

Project Aprilia SR50: 100 MPG Madness Part 2, Engine Internals

By Mike Kojima

In our last edition of Project SR50, we had reached the limits of simple bolt on modifications which left us with a nicely running Scooter, capable of just over 50 mph with acceleration good enough to keep up with traffic and 115 mpg. With more time, we are really taking a liking to the refined Aprilia SR50, which rides, handles and brakes better than any scooter in this displacement category. We also like its sporty looks. The SR50 is the king of urban commuter scooters and we are going to take it to the next level.

The Best-Engineered Cars of LeMons - #3: Angry Hamster PART II

By Dave Coleman

At 1400 lbs and 116 hp, the Angry Hamster has the power/weight ratio of an S2000. It packs a mid-mounted, 10,000-rpm V4 engine mated to a 6-speed sequential dog box, and puts its power down thorugh a limited-slip diff. Weight distribution is a dead-even 50/50, and the wheelbase is nearly a foot shorter than a Lotus Elise's. And all of it was built for $449.
