How to Pass Tech Inspection for The Drift League and Other Events!

By Mike Kojima

As the Technical Director for The Drift League, I was pleased that the quality of many of the Pro-Am cars that myself and Nikita Rushmanove were high and we have plenty of solid cars in the series. On the other hand, I was dismayed at the fact that NONE of the cars we inspected passed tech the first time through!

Project DC2 Integra, Testing the Fluidampr Crank Pulley

By Mike Kojima

We have big plans for Project Integra B18C engine.  Instead of swapping to a K Series engine to make easy big power, we are going to build up the older but still noteworthy B Series engine that the car comes with. Something that is relatively easy due to this engines huge level of aftermarket support.

Project GT3RS Getting More Power With Dundon Motorsports Part 2

By Mike Kojima

The Porsche GT3 RS is a supercar with state of the art engineering in the powertrain department.  It has a naturally aspirated 6 cylinder flat 6 that pumps out an amazing 125 hp per liter.  The 9A1 engine has an 8800 rpm redline and a stratospheric 13:1 compression ratio which it somehow runs with on pump gas, even California's crappy 91 octane pee water, with the aid of direct injection.

Sign up for the Hellafunctional Showdown & Super-G Track Battle!

By Mike Kojima

We have been busy laying out the course for the Super-G Track Battle portion of our MotoIQ Hellafunctional Showdown presented by KW that is going to happen during the halftime portion of The Drift League competition this Friday at Irwindale Speedway. I can assure you that it is both fun and challenging, but not so rigorous that it will wreck your street car! The Super-G course is a drag race, road race and autocross all thrown together and requires a maximum G stop into a box. So it is a great judge of your overall driving skills.

Inside the 1000 hp LS, Dai Yoshihara's Formula Drift Powerplant

By Mike Kojima

MotoIQ Garage has taken over the development of Dai Yoshihara's engine program for the last two years from a famous high dollar engine builder. The previous engine had decent power but the reliability was lacking. We were experiencing some sort of engine related issue every few events and halfway through the season, the engine performance would degrade and a fresh engine would need to be installed.

Can an Oil Change Make More Power? We Test Idemitsu ZEPRO Eco Medalist and Find Out!

By Mike Kojima

Can you make significant power gains just by changing oil?  In the past, we have proven that switching from a lower grade mineral oil to a premium synthetic oil can be good for a couple or three hp. However, is it possible to make serious gains in power from just an oil change by changing the viscosity of the oil as well as the type?

Ryan Passey's Amazing Mazda Hyper Miata

By Mike Kojima

We have always liked the super-efficient cars of Moti Almagor's Blackbird Fabworx. His cars have a distinct signature; lightweight, elegant, very fast with very little horsepower. Focus is put on maximizing handling, braking and cornering grip in a simple package. Recently at the last Global TIme Attack event at Buttonwillow raceway we got to check out Ryan Passey's, of Goodwin Racing, 1990 Mazda Hyper Miata that was built by Ryan in collaboration with Blackbird Fabworx.

Dai Yoshihara's 2018 Formula Drift Rebuild Continued!

by Mike Kojima

So the rush to freshen Dai's car for 2018 by Eimer Engineering continues. In our last story, the chassis had gotten acid dipped and the cage and a few other things had gotten some working over for improved stiffness and increased simplicity. 

Now the car is getting reassembled for a quick shakedown run at Irwindale and some more extensive testing at Willow Springs this week. So let's take a look! There are a lot of right ways to build a car here and anyone can benefit from looking at how our car is put together.

Team America BNR32 GT-R First Update in a Long Time!

by Mike Kojima

So most of you probably thought that the Team America GT-R was dead, long abandoned to the scrap heap or maybe left in a pile somewhere in Australia. Not so! After a humiliating first appearance at the 2014 running of WTAC down under, the car has been under reconstruction.

Project Porsche 991 GT3 RS: Dundon Motorsports Headers and Exhaust System

by Mike Kojima

It's tricky to attempt to improve the engine performance of a supercar, especially when its one that puts out 125 hp per liter like the Porsche GT3 RS does. When it comes to NA power, only the Porsche 918 hypercar and the Ferrari 458 Speciale have more punch per liter. With its screaming 8800 rpm redline, titanium internals and a sky-high 13:1 compression ratio, there isn't a whole lot more that can be done without serious engineering, beyond what most tuners can do.

Project Corvette Stingray C7 Z51: Remodeling the Interior

by Mike Kojima

The C7 Corvette's interior is a huge step up from its predecessors. Previous iterations of the venerable Corvette might have been awesome cars, but the interiors were plastic clad and had the look of a cheap rental car. Not so with the C7.

Improving Dai Yoshihara's Formula Drift Engine Wear With WPC Treatment!

by Mike Kojima

The world of Pro Drifting is a brutal place for machinery. Since I started my involvement with Pro Drifting 10 years ago, I have been amazed by the appetite for parts a pro car possesses. In all of my engineering career, I have yet to be involved with a motorsport that eats more expensive stuff on a regular basis.

We Visit the Nitto King of The Hammers Powered by Optima Batteries! Or, the Idiot's Guide on How Not To Go Off-roading

by Mike Kojima

So we were ecstatic when Nitto Tires and Hellwig Products, makers of cool suspension stuff and supplier for several of MotoIQ's truck project suspension goodies, invited us out to the desert to spectate the Nitto King of The Hammers Powered by Optima Batteries off-road race.  Although we are newbs to the whole off-road truck thing, we know enough to have heard of the event and know that it is an extremely tough test of man and machine combining the rigors of both off-road desert racing and bolder crawling together in one event.

Project Porsche 991 GT3 RS- Improving the Aero with a 911R Rear Diffuser

by Mike Kojima

How do you improve a supercar? It is not easy, but leave it to us to give it a try. We recently got to add a Porsche GT3 RS to our project car fleet. If you don't know much about Porsches, a GT3 RS is a limited production model, part of the current 991 platform family and the last of the great naturally aspirated 911's.

Project DC2 Integra- Getting More Grip With OS Giken and Better Response With Centerforce

by Mike Kojima

With our DC2 Integra rocking a state of the art suspension, it was time to get our drivetrain in order for our anticipated track use and increased power. To get the power to the ground, we needed a limited slip differential, and we selected what we feel is the best FWD limited slip on the market- the OS Giken 1 way differential.
