Let’s face it, autocross is hugely popular. There is a statistic floating around that the SCCA Solo II Nationals is the largest motorsport event in North America. While I have not audited that fact, I can tell you that a LOT of people love the sport. In fact, my very first interest in automotive performance was an autocross event that I attended and competed in after being encouraged by a friend to give it a try. After that event out came the stereo and in went suspension modifications. That car was Project 200SX and the year was 1999. I have always had a penchant for the sport but after spending more time at the road course, life sideswiped me and my participation in AutoX events waned; that is, until recently.

Fuel systems upgrades vary drastically and sometimes only a simple pump or injector change will suffice. Other times, like in this project, it seems like every component in the entire system needs to be changed. Recently, in Part 2 of Project RX-7, we covered the engine side of the fuel system, where the injectors, rail, and pressure regulator were upgraded. Now it's time to discuss the remaining fuel system upgrades that we are so eloquently dubbing the "chassis side."
Modern diesels are light years ahead of their predecessors when it comes to power. No longer is the diesel owner subjected to white-knuckle freeway merges at school zone speeds, scary amounts of noise, smoke-screen plumes and honking horns as fellow motorists pass them with windows down. That doesn’t mean there they can’t be faster. This goes doubly true when you consider Project Golf TDI’s sporty looks. Getting passed by Mom in the minivan with nary a glance was getting a little depressing.

There are three key ingredients for combustion in any gasoline engine: air, fuel, and spark. Parts 2 and 3 of this project will focus on the fuel component of this recipe. Rest assured, this won't be your typical run of the mill RX-7 fuel system.
In Part 4 we witnessed an aesthetic transformation and a dramatic improvement in all performance categories, especially braking. Going from 60-0mph in 10 less feet, or experiencing a 0.14G improvement in deceleration, after all, is hardly going to go unnoticed. What will go unnoticed--until pad failure or fluid boil--is the increase in heat throughout the brake system, which we tackle next!
With all the parts needed to move forward, Project Supra is now on pace to get fired up! Not only are previously featured parts installed, but we continue to add new stuff as well.

We test a wheel and tire package with eye opening results! The M3 is now quicker, handles better, stops on a dime, and also turns more heads. Check out our numbers!
Now we’re getting into the exciting bits of Project E36 M3. It’s been a joy to drive in mostly-stock form, but it’s time to get into the real fun: Suspension!
The groundwork for our suspension project began a few months ago when I had a meeting with Brian Hanchey of Hanchey Vehicle Technologies (HVT) while we were at Kansas Speedway’s GRAND AM race weekend. The prospects of our discussion had me bouncing off the walls with excitement.
As the SEMA Show approached, we knew we had to do something a bit different. We knew that the show would probably be flooded with tons of FR-S's and BRZ's. We also knew that most of these cars would be sporting either 5-Axis or Rocket Bunny aero kits.
At MotoIQ we are not the guys that build show cars so what could we do to stand out amongst the scores of nearly identically modified cars? We figured we would stick to what we knew best and try to build something functional and not worry about the looks, hoping that by following the old adage that form follows function, we could come up with something appealing in a shot time.
When the nerd-herd decided to upgrade the brakes on our Project Scion FR-S, we of course turned to our partners over at StopTech and found they had their world renowned Trophy Kit available for the front and rear of our FR-S. So of course we had to get our hands on a set to put it through its paces and document the installation process. During the installation of the Big Brake Kit (BBK), StopTech was a huge help providing technical support along with some tips we found to be very useful...so we created a series of videos to help out all you DIY'ers out there.
