Revenge of the Nerd: Bravo Toyota!

By Mike Kojima

Today Toyota announced perhaps what is the most extensive, comprehensive and expensive recall in the history of Automotive manufacturing.  The recall involves eight of their best selling models from the Camry to even our Project Tundra.  2.3 MILLION vehicles will be affected by this recall. In an unprecedented move, Toyota has also stopped all sales and production of the potentially affected models as well. This affects more than 100,000 brand new Toyotas in the sales pipe line.  This is STOPPED, dead cold, with thousands of workers at plants and dealerships who as of next Monday will be sitting around twiddling their thumbs. This recall will probably be disastrous financially for Toyota.


Project Pathfinder Cams, ECU's, & Headers

Project Pathfinder Part 8, Cams, ECU, Headers

By Mari Umekubo

The stock VG cam shafts are very mild.  At the advice of the guys at Nissan Motorsports we added a set of their #2 off road cams to Project Pathfinder.  The cams have 264 degrees of duration and .430” lift with a 106 degree intake and 116 lobe center as opposed to the tiny stock 248 degrees duration and .374” lift with 114 lobe centers.  This is quite a difference and the cams really woke Project Pathfinder up.

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.

Read Part One about how the clutch pressure plate works Here!
