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.


Squirrel Power: Making a Minibear Part 1

by David Zipf

It’s been a while since we talked about our little Suzuki FA50 runabout. You’d be forgiven for thinking it had been abandoned or sold. But fear not! Neither is true. In fact, this thing has been the perfect little around town commuter, running beautifully for the last year and a half. Aside from a minor oil pump problem, we’ve had almost no trouble with our little Suzuki. Unfortunately, it is still as slow as ever and we really need to fix that. And fix that we shall!


WATCH: MotoIQ Approved Feature Car! A Track Ready, Comptech Supercharged 1991 Acura NSX

We take a detailed look at Regan Yu’s very well built Acura NSX that he uses for frequent track days and casual street driving. How do you make one of the best Japanese classic cars even better? Grab a seat and get ready to learn from MotoIQ’s Editor-In-Chief and Engineer, Mike Kojima, as he goes step-by-step through this well thought-out build.


Project V8 E46 M3 Racecar: Adding KW Motorsport Suspension and StopTech Trophy Big Brakes!

by Mike Kojima

When we last left our E46 M3 Project, it was a body in white shell with a cage in it at Pure Performance. Pure started to build the car with an S65 V8 engine from an E92 M3 with a DCT transmission.


Quick Tech: Blowfish Brake Duct Install for BOSS 302

by Mark Gearhart

When it comes to track cars, there’s only so much heat dissipation a rotor can provide before itself becomes overheated. So how do you bring down the blazing braking temperatures even further? A fresh air duct system. We install a Blowfish Racing brake duct system on our Project BOSS 302Revival!


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.


Doodlebug of Doom Part 2: Taming The Beast

by David Zipf

First we fixed the Doodlbug.  Then we rode the Doodlebug.  Then we changed our pants and parked the Doodlebug.  Now, we fix the Doodlebug again so we no longer need to ride with the brown pants.


Project GMC Canyon: Introduction and Icon Stage V Suspension

by Isaac Sandoval

I can't tell you how long I've dreamed of owning a mid-size pickup with a small diesel engine and 4WD. Living in Southern California, we are surrounded by plenty of great desert trails to explore. Another wonderful thing about living in Southern California is that our fuel taxes are high AF! Seriously, the taxes on fuel just went up again, and there is just no way I could justify having one of our two family vehicles be a complete gas guzzler. Enter the new 2.8 liter Duramax 4 cylinder diesel engine. This thing is a real gem when it comes to efficiency. The GMC Canyon Diesel is the highest rated MPG truck on the market. Period. No time is wasted with this project truck, and we install Icon Stage V suspension in this series. Read more to find out what we think!


We Test the Bimmerworld Exhaust and Epic Motorsports ECU Tune for E90/E92 S65 V8 BMW M3

by Pablo Mazlumian

When the S65 4.0-liter V8-powered M3 was released, enthusiasts loved the power, thanks to its 8000-plus RPM capability. However, many also deemed it not torquey enough for a V8. With this exhaust setup and tune, an M3 will make some torque, as shown in our testing at Modified by KC.


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.


WATCH: $1500 for a LSD?!?! Why the OS Giken Super Lock Limited Slip Differential is worth it!

MotoIQ Video

We recently installed an OS Giken Super Lock limited slip differential on our Project DC2 Integra! Watch as Mike Kojima explains everything you ever wanted to know about LSD but were afraid to ask! The OS Giken Super Lock 1-way differential completely transformed our Integra, and even at a price point around $1500, it's one of the biggest bang for the buck performance modifications you can do on a front wheel drive car- especially if you take it to the track!


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.


Dai Yoshihara's 2018 Formula Drift Rebuild

by Mike Kojima

After 3 years of Formula Drift competition, our team had pretty much developed the BRZ chassis to where we were satisfied with its performance. After some post-season testing to try out a few new ideas we decided that with the development stable, it was time to completely go through the car, repair some minor damage incurred during three seasons of hard use and to rethink the car's layout.
