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.

Project C7 Corvette Stingray: Introduction Part 2, A Closer Look at the LT1 Engine

by Mike Kojima

In the last edition of Project C7 Corvette Stingray, we were doing an overall look at the car including it's mostly all new LT1 engine. As we were saying, although the LT and LS share the same architecture, they are indeed very different engines. They are so different that they only share a handful of parts. 

The LT1 is a vastly different engine that has a lot of development differences over the already excellent LS3 engine and deserves a closer look at some of its unique internals. Most of the differences are to improve fuel economy, emissions, torque and powerband width, but there are are some tweaks to make more power overall as well. Take a close, detailed look with us!

Tested! Honeywell Garrett Upgraded Intercooler for the EcoBoost Mustang

by Mike Kojima

Honeywell by Garrett has recently released a direct fit bolt-on intercooler solution for the EcoBoost Mustang, and we didn't wait any time to verify how it performs! We knew our friends at HPS Performance Products had been time attacking their EcoBoost Mustang, so it would be the perfect test bed for our intercooler test. Read on for all the details and DATA!

Project V8 RX-7: Part 17 – Eimer Engineering Arms, Wheel Spacers and the Hunt for Perfect Stance

by Mike Kojima

In our last articles about Project V8 RX-7, we left you last with photos of our new SSR Professor SP4 wheels and Toyo R888 tires looking flush, but we weren’t ready to explain how we accomplished that task yet. With our Rocket Bunny aero kit giving us a huge space in the wheel wells to fill, we were going to take advantage of all of that.

Our car had to use all of the space for wide wall-to-wall rubber. More rubber means more grip, and with our LS3 providing the torque and power to use it all, we were obligated to do so. However, just putting wide rubber on a car not designed for it creates a few technical issues that, since we are MotoIQ guys, have to be engineered out of the equation. This means the typical spacer to fit and beat to match approach was not going to be a solution.

Whiteline S550 Ford Mustang - Introduction and Initial Testing

by Mike Kojima

Recently, Whiteline obtained a late model S550 Mustang to function as both a test mule for their S550 chassis parts development program, but to also act as a rolling showcase for their Mustang product line. The Mustang will also feature upgrades to the engine, braking system, and the car's cosmetics to make it an all around performer. We will be documenting the build and testing progress here on MotoIQ.

Project C7 Corvette Stingray Z51: Introduction (Part 1 of 2)

by Mike Kojima

MotoIQ recently suffered a great loss, our project Golf TDI. A victim of the great VW emissions scandal, we got a cash deal we couldn't refuse to return her to the motherland for whatever VW plans to do with all those dirty diesels. Although getting great money for a well-used car is always good, it still left us short one very versatile daily driver.  

So the search for the next MotoIQ long term project car started. We looked at a bunch of other cars to try to find a new unicorn. While we were in the showroom waiting on the sales dude to get pricing on something else, we sat in a C7 Stingray on a whim. The rest became history, and we finally found our next project!
