Project Unpimp My Ride: Pedders Easyfit Suspension and Swaybars, Street Performance for the Toyota86/BRZ/FR-S

by Mike Kojima

Not all of us want a race car for the street. Although many of us are hardcore track day participants, autocrossers or canyon runner nuts, there are a lot of enthusiasts who don't want a super edgy race car with a license plate as a commuter or daily driver.

Project Corvette Stingray C7 Z51: Body Modification

by Mike Kojima

Typically aftermarket aero parts are lame; they don't fit and have gaps. They require you to drill holes in your body panels for sheet metal screws. The carbon deteriorates in the sun and gets cloudy. Not so for these Chevrolet Performance offerings. They fit perfectly and are built to the same OEM durability standards as the car!

Building an FA20 Race Engine for Michele Abbate: Part 1- Planning the Internals

by Mike Kojima

We have known Michele Abbate ever since she was a college student doing track days with her trusty Mazdaspeed Protege and have followed her career as friends as she has progressed up the ranks from recreational driver to a Scion Sponsored driver in SCCA's GT1 class. 

Up to now, Michele has been running her car with a bone stock FA20 engine at a very low boost street blower drive ratio. Although this is decent power, she needs a lot more to be competitive in one of SCCA's fastest classes for production-based cars.

Project C7 Corvette Stingray Z51: Suspension Upgrades

by Mike Kojima

In previous articles about our Project C7 Corvette, we got into the high tech chassis construction of the C7 that rivals the stuff found in exotic cars for a fraction of the price. We also did our baseline testing of the car at Buttonwillow Raceway to get an initial impression of the car. We were quite impressed with the results. In stock form, the Corvette is one of those cars that is so good from the factory that heavy-handed, poorly conceived aftermarket suspension mods can ruin.

An inside look at the Feal 441 Suspension for the B13 Sentra SE-R!

by Mike Kojima

The original B13 Sentra SE-R has always held a dear spot in many of our hearts. Produced from 1991 to 1994, the SE-R combined the lightweight shell of the Sentra coupe with the sparkling performance of the beloved SR20DE engine. For its time, the SE-R offered a great performance bang for the buck, and to this day, it has scores of hardcore devotees who treasure them.

We Look Inside Fredric Aasbo's Papadakis Racing Toyota Corolla iM Drift Machine

by Mike Kojima

It is really hard to build a competitive car in Formula Drift nowadays. The rules set is mature, and the competition is ruthlessly tough. When even the best teams develop a new platform, it can take a whole season to sort a new chassis out. A radically different chassis can take a couple of seasons for even a top team to get competitive. Not so for Papadakis Racing and their Rockstar Toyota Corolla iM that they built for 2015 Formula Drift Champion, Fredric Aasbo.

Tested! Weego's Lunch Box Automotive Power Source

by Mike Kojima

We get all sorts of cool stuff in the mail at MotoIQ's palatial mega-garage. Manufacturers send us stuff in hopes that we will test it and write about it. This means that we have more than our share of miracle lubes and additives, car care products and weird gadgets. Most of these things end up not working, so well so you never read about it here. However, the other day we got a box from a company we had never heard of called Weego.

Project C7 Corvette Stingray Z51: Improving Stopping With a Chevy Performance Big Brake Upgrade Kit

by Mike Kojima

When we did our baseline test of Project C7 at Buttonwillow Raceway configuration 13 CW, we were pretty impressed with the stock Z51 Stingray's on-track performance. We felt the chassis was set up pretty well for the wheel and tire configuration that came on the car, and the whole chassis calibration was matched to the amount of tire the stock car had and the power level of the engine.

Project DC2 Integra: Truing up the Suspension with Whiteline

by Mike Kojima

In the last edition of Project DC2, we greatly improved our car's suspension by replacing the ancient, worn out Koni Yellow shocks with some state of the art street KW Suspension Double Adjustable Variant III coil-overs. When paired with a stock front anti-sway bar and the excellent Comptech rear anti-sway bar that came with the car, we had a well-balanced combination that worked pretty well on the track and the street.  

All was good, but we wanted to go through the entire suspension and replace all of the old and well-worn rubber bushings in the car with new, hard polyurethane parts from Whiteline. This would bring our suspension up to snuff with the current best stuff out there.

Project GD STI: Making the Front of the Car Stiffer with Ultra Racing

by Mike Kojima

In the last installment of Project STI, we had greatly increased the chassis stiffness with a full complement of Cusco braces. From our EVO project, we had found that on the CT9A chassis, the braces that did the most were the fender braces that add reinforcement from the strong door hinge area to the top of the shock towers. From this experience, we wanted to add similar braces to our STI.

Project Tundra: 5000 Mile Evaluation of Nitto's New Ridge Grappler Tires!

by Mike Kojima

We were very pleased with the Nitto Terra Grappler tires that Project Tundra had been running the last 7 years. We had over 60,000 miles of towing, supercharged burnouts, daily driving and off-roading on them- including a day of driving hard around Willow Springs Raceway. We were very pleased to note that they still had at least 70% of their original tread and still worked quite well!

Hondata's Land Speed Record Honda CRX

by Mike Kojima

A lot of armchair racers like to comment on Land Speed Racing saying things like "how hard could it be to go 200 mph at Bonneville, it's a big flat dry lake, all you have to do is floor it" or "I can almost go that fast down the freeway with my Civic with a turbo kit".  Well, all we have to say about that is to go try and find out just how good you are if you think you can.

Project GD STI: Getting Rid of Chassis Flex with Cusco

by Mike Kojima

The GD STI/WRX had what was considered to be a very stiff chassis when it was first released internationally in 2000. The new Impreza platform was built to be much stronger than it predecessor and used much of the experience gleaned in rally competition to build a chassis that was over 100% stiffer than its predecessor. However, that was 17 years ago, and the design that was once the leading edge in unibody chassis integrity is now something that is just average.

Project Bugeye GDA WRX: Fixing the Clutch with Exedy

by Mike Kojima

Poor Ian, MotoIQ's FNG's daily was his trusty Bugeye GDA WRX. The WRX has given many years of faithful service, but since joining the MotoIQ crew, Ian's commute has gotten much longer and the miles were taking their toll on the car which has over 200K miles. To make matters worse, on his way to work, the car sprung a huge oil leak and oiled down the super old clutch, and Ian barely limped into the MotoIQ garage.

Project EP3 Civic Si: Fixing the @$#%! Steering for Good with SHG Motor Works!

by Mike Kojima

In our last edition of Project EP3 Civic Si, we thought we had fixed our car's bump steer and wandering steering with a roll center correction kit and a bump steer kit from Hardrace. Our car had serious issues since day one. When we first got it, no one wanted to drive it because the car would wander around on the freeway and everyone was afraid of getting pulled over for drunk driving.

So, we installed a bunch of suspension stuff and finished it with the Hardrace geometry correcting parts in the front suspension. With the car finally handling well, which is no small task with an EP3, we were finally having fun driving it hard. All was good for a couple of weeks, but then the wandering steering returned with a vengeance.

Project DC2 Integra: Starting the Journey Toward Better Lap Times with KW Suspension

by Mike Kojima

If you've been paying attention to our DC2 project car, then you know in the last installment we took our car to Buttonwillow Raceway (CW13) to record its baseline lap times and to get some driving impression of its 150,000-mile suspension and tires. Surprisingly the old DC2 was not horrible and not the slowest car entered in Global Time Attack's first ProAm event of the year. 

However, we never settle for "good enough" at MotoIQ, so we're outfiting our Integra with a set of KW Suspension Variant III coilovers as we embark on the journey towards better lap times.

Top Lube for E85?

by Mike Kojima

Admittedly, none of us on Dai Yoshihara's Formula D team have much experience with alcohol. We all knew methanol was a superior fuel but highly corrosive. We knew it would require a lot of post event maintenance, which would include pickling the engine and fuel system by draining the methanol and running gas through the system to remove the methanol. However, we didn't expect to run into the issues that we did. We needed a solution and were recommended some things from other teams' crew chiefs that all came down to one thing.

The Tech Garage Low Cost Borescope!

by Mike Kojima

Just a few short years ago having access to a borescope was a luxury that few racers, engine builders, and hobbyists could afford. You would typically have to spend a few thousand dollars for one. They were not that flexible, in that you would either not be able to record images or would have to spend a bunch of money for camera adapters.

Project GD STI: Making More Power with Cobb Tuning and Precision Turbo Part 2!

by Mike Kojima

When we last left off with Project GD STI, we had just installed our drop-in ball bearing center section upgraded Precision Turbo. In our opinion, this is one of the best drop-in, non rotated mount turbos on the market for these cars, however, we wanted to be able to turn the boost higher. This brought the need for a tune utilizing Cobb Tuning's Subaru Flex Fuel System.
