Project Racer Part 8: Nissan SR20DE S4 Cams from Jim Wolf Technology

By Annie Sam

So what was the cherry on top of our Nissan SR20DE horsepower upgrades? S4HL Camshafts from Jim Wolf technology. What are cams? First, let’s start off with the term “cams”. Cams are actually the lobes of the entire assembly, which is more formally known as the camshaft. But, for this article, we’ll stick to calling them cams, as that is the casual term for the part. So, let’s give a little introduction on the basics of cams.

Mike Kojima Revenge of the Nerd 


By Mike Kojima

My involvement this year supporting Dai Yoshihara and James Deane with Falken Motorsports in Formula D drifting has been a wild ride.  It was a very interesting learning experience as I finally discovered what the dynamics of a really good drift car are and how to set up the chassis to deliver the performance a driver needs to do his job.  Modern Pro drifting is probably the greatest challenge for chassis set up out of any sedan based motorsport and the SPD Metalworks crew works pretty hard to get the car just right for any given course. 




Nissan's MR16DDT 1.6L Direct Injection Turbo Engine

by Eric Hsu

Nissan's exciting new MR16DDT engine has all of the features and stats that you would want in a kick ass engine. It also sounds like it may have what it takes to be Nissan and/or Renault's entry as the GRE (global race engine). Imagine seeing this engine in the back of an F1 car...

Sierra Sierra EVO Update & BorgWarner EFR Turbos

by Eric Hsu

The last test at Buttonwillow was the straw that broke the camel's back both for the choice of turbocharger and the cylinder head sealing issues. You can see the despair (and my head scratching) in the picture above, but with any down there's always going to be an up. BorgWarner with their EFR turbo lineup and Cosworth with our turbo race engine experience are coming to the rescue.

Elmo makes some more progress on his bad ass CRX. AP Racing monobloc calipers, Recaro Kevlar buckets, and other goodies make this CRX probably the most baller CRX around.

BNR32 Skyline GT-R Stage 1, Part 2

by Eric Hsu

The Stage 1 build of my personal BNR32 Skyline GT-R is a 500+whp, pump gas, street car designed for good throttle response and mid range torque for smokin cars on the street and track alike. Anyhow, this is part 2 of the Stage 1 build where I will break down in detail why I chose the parts I did.


Fast Lap with Billy Johnson:  Laguna Seca (Video Inside)

By Billy Johnson

Mazda Raceway Laguna Seca, previously known simply as “Laguna Seca” was built in 1957 on the land of Fort Ord; which was a maneuvering area and artillery target range for the US Army.  World-renowned (by the help of Playstation video games for the younger generation), the track has hosted Champ Car, ALMS, Grand-Am, Moto GP, World Superbike, Formula 5000, Trans-Am, Can Am, and has been the site for several very memorable races.  In 1988 the track was increased to its current 2.238 mile, 11-turn configuration with 300 feet of elevation change and the world-famous “Corkscrew” Turn 8.
