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!

Tested: Mirror Bright Vinyl and Rubber Treatment

by Mike Kojima

We usually don't get excited enough about car care products to write about them, but every once and awhile, we get something in the mail that gets our attention. Tire treatments are something we could usually care less about. The market is saturated with all sorts of goop to put on tires.

Project EP3 Civic Si: Can an Oil Change Affect Horsepower?

by Mike Kojima

A lot of people have asked this question before, and the jury has been out on whether this is something that is true or not. We have attempted to test to see whether certain brands of high-quality oil have a gain in power over others before with mixed results. Our dyno tests have always been inconclusive with the differences being too small to be considered or perhaps caused by variables such as differences in viscosity or sump level.

Project EP3 Civic Si: Fixing EP3 Bumpsteer with Hardrace

by Mike Kojima

In prior editions of Project EP3 Civic Si, we went over the history of the car- the worst handling Civic made with suspension geometry taken right from the Stream minivan. Well, so far we have gotten rid of squishy rubber and added sway bars with help from Whiteline. We also got rid of the flaccid shocks with a set of coilovers from Fortune Auto. Now we will address bumpsteer issues with Hardrace!

Project EP3 Civic Si: Installing Fortune Auto 510 Coilovers!

by Mike Kojima

Over the past few installments of our EP3 project, we have been working on fixing on what is perhaps the car's major weak point, the handling. Previous Civics were known for excellent handling with 4-wheel multi-link suspension. The EP3 however, uses the suspension from a Japanese market Stream van in a really dumb case of parts bin engineering.

Project EP3 Civic Si, Suspension Upgrades with Whiteline! 

by Mike Kojima

So everyone into Hondas just about universally ignores or even hates the dumpy EP3 Civic. The EP3 represents, to most Honda fans the generation of Civic where Honda lost their brand identity and started to make cookie cutter shitboxes.

Lessons in Turbo Technology with Garrett - Burst Containment

by Mike Kojima

What is burst containment for a turbocharger, and why is it important?  A turbocharger is a system that has a lot of potential to cause a lot of bad stuff to happen to drivers, spectators, and surrounding equipment.  Why, might you ask? Well, a typical turbocharger can spin at up to an unfathomable 200,000 rpm for a small frame turbo and a still amazing 90,000 rpm for a large frame turbo!  That is a ton of potentially ass-kicking force. We will show you how much later and it's enough to make you cringe.

Project EP3 Si: Going 5 Lug with Wheels from Enkei and Nitto NT05 Tires

by Mike Kojima

Now that we converted our EP3 Civic from 4 to 5 lug hubs and added big brakes, there was no going back.  In order to drive the car, we obviously needed to do something about our wheel situation.  Our goal was to stuff the biggest tires we could into the stock wheel wells.  Unlike our hellaflush brethren, we want big and we want traction, not stretching a narrow tire on a wide rim and stupid amounts of negative camber.

Japanese Cars That Don't Suck

by Mike Kojima

I pissed a lot of people off with my Japanese Cars Suck article a few weeks ago, where I expressed dismay at the boring state of the Japanese car industry. Japan Inc. seems to be producing either the uninspired transportation device or the trying too hard, over the top stuff that seems like something out of the Fast and the Furious or Transformers franchises.

Project EP3 Civic Si, Improving the Brakes with Fastbrakes, Stoptech and Willwood

by Mike Kojima

In the last edition of Project EP3 Civic Si, we explained how we went about converting our car from 4 lug to 5 lug hubs. We did this for two reasons: one to take advantage of the larger selection of 4x114.3 bolt circle wheels available on the market and to take advantage of the larger RSX Type-S wheel bearings and axles to stiffen up the bearing system in anticipation of performance fixed caliper brakes and more power from a possible engine swap.
