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 SR E30: Part 1 - Test Fitting the Engine

by Nikita Rushmanov

So, you built an s13 daily with an SR20 in it. It’s reliable, it’s fast, it makes awesome chu-chu noises, you put 5,000 miles on it, but then you realize that there is one thing this car doesn’t have- 4 doors. That is the exact predicament we were in.


 

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. 


 

Nerd Alert! Mazda’s Skyactiv-X Engine

by Khiem Dinh

As we are sure many of you have heard, the little car company that could, Mazda, has announced their Skyactiv-X engine with the technology to run Homogeneous Charge Compression Ignition (HCCI). Two major challenges to make HCCI work: timing of the combustion and smooth transition between HCCI and regular spark ignition. The HCCI combustion process has been researched for decades, but the technology to bring an engine using HCCI to market has been elusive until now.

So how did Mazda do it? We are going to take a few guesses, but as with most technologies, it didn’t happen overnight. In fact, we would say Mazda’s first big step was a few decades ago. The final piece of the puzzle is a technology Mazda has called Spark Controlled Compression Ignition (SPCCI), and we will exclusively get into how that ties into making HCCI work.


 


Project E46 BMW M3: Part 19 – Rear Trailing Arm Bushings and Maintenance

by Pablo Mazlumian

BMW rear trailing arm bushings are rubber and prone to cracking. Ours cracked and rendered the car uncontrollable at the limit. We give you step-by-step how-to on installing Powerflex polyurethane bushings from BimmerWorld!


 

Building the FR-S FA20 with Stay Crushing: Installing the Engine and Making Big Power!

by Mike Kojima

If you have been following our story, we are now ready to install the engine in the chassis.  Our engine has been built for durability with forced induction, and it was time to put it in the chassis to get it tuned!


 

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. 


 

TESTED: BG Syncro Shift II Synthetic Gear Oil

by Billy Johnson

Changing out the factory transmission fluid for a higher performance oil is a common solution to reduce the notchy-ness and improve shifting feel. This is especially important in the Getrag MT-82 used in the 2011-2017 Ford Mustang. While we already changed out the trans fluid in our test car, Tim at OPMustang.com said I “HAD TO” try the BG Syncro Shift II Synthetic Gear Oil. I wasn’t really motivated, since the current Royal Purple Synchromax was already a big improvement over stock, but Tim offered to buy me a steak dinner if I didn’t think there was an improvement, so I gave it a try.


 

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. 


 

Wrench Tip: How to Do Your Own Alignment!

by Nikita Rushmanov

When most people hear the word alignment, they think of two things-- lasers and alignment racks. There is a preconceived notion that in order to achieve an accurate alignment, you need a $50,000 alignment rack. That is simply not true. With a little ingenuity and math, you can achieve extremely accurate alignments without any expensive tooling whatsoever. When racers hear the word alignment, they think of strings and levels. 


 

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.


 

WATCH: Project C7 Corvette Gets an AEM AQ-1 OBDII Data Logger! 

Just like Project DC2 Integra last week, we're taking our Project C7 Corvette out to Buttonwillow in 100% stock form for some lap testing courtesy of our friends at Global Time Attack.  Unlike the Integra--who's too old to know what a CANbus is--we're installing an AEM AQ-1 OBDII data logger in the Vette before we hit the track.  AEM's AQ-1 OBDII Data Logger is easy to install and logs engine data transmitted from the CANbus signal feed in the OBDII port of any 2008+ vehicle.  The AQ-1 also has a 3-axis accelerometer built in so we'll be able log g-force data as well!  Take a look at today's video to learn more about it and see how easy it is to install!  And remember to swing by again next week for the results of our C7 baseline track test before we install all the Chevrolet Performance parts heading our way!
