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.

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.

anti lag rocket beyond the dyno

External Combustion Rocket Anti Lag System + JDM Spec C Impreza STI

By Eric Hsu 

The external combustion anti-lag "rocket" combustor was used on the factory Prodrive built WRC STi Subaru cars to improve the EJ20 engine's inherent mediocre torque and engine response. The rocket is so good that a version of it is still in use today in the 2012 Japanese Super GT GT300 STi BRZ which also uses an EJ20. Last time I wrote a teaser article, but this time we'll take a look at some of the details of the rocket combustor anti-lag system as it applies to my buddy Ben's JDM Impreza STi Spec C street car over in the UK.

The Continual Beginner

by Christy Carlson

Repetition leads to boredom. Boredom leads to unrest. Unrest leads to new beginnings. Well, that, and running out of means will force a person to "reconsider the options available" in a fairly brisk manner. I've been precariously balancing the pocketbook of life for a while, be it health or wealth, youth and unrest, ambition and means. This is my life in motorsports, starting at 25.

Building the Subaru VA WRX clutch and Flywheel with ACT!

by Mike Kojima

All wheel drive cars are traditionally hard on clutches. With tons of traction, launches involve a lot of clutch slippage. Fast shifting and even downshifting are all harder on the clutch due to the increased traction of 4 wheels.  With this in mind building a daily driver heavy duty clutch for a street car is always a challenge. 

It just so happened that our friends at ACT were wrapping up development of a clutch and flywheel combination for the late model VA WRX when we were at their office and we thought it might be a good opportunity to show what is deep inside ACT's WRX clutch which shares many design features with all ACT clutches.

Project VA WRX: Enhancing Grip with ARK Design R5 Wheels and Nitto NT05 Tires

by Mike Kojima

Our VA WRX is becoming quite impressive thanks to the gains we have made in its performance.  We are beginning to think that it will soon be knocking at and even exceeding the performance envelope of the much more expensive STI.

Since we have been working on the brakes and suspension of our STI killer VA WRX, it was time to take advantage of those parts with some bigger, grippier tires and wheels to accommodate them. We got the right hardware for the job with some wider wheels from ARK Design and bigger tires from Nitto Tire.

Project VA WRX: Upgrading the Brakes with Stoptech Part 2 - Getting it Done!

by Mike Kojima

In our last edition of Project VA WRX we showcased some of the preliminary testing involved for the design validation of our new big brake kit by Stoptech.  A baseline for the stock brake system was established using Stoptech's test protocols. The brake testing establishes the brake balance, stopping distances and fade characteristics of the stock brakes so improvements can be measured and there is a record of the validation testing.

Project VA WRX: Upgrading the Brakes with Stoptech Part 1 - Getting a Baseline

by Mike Kojima

Our Project VA WRX does not have the trick Brembo brakes that come standard on its big brother the STI.  It does however have brakes that would have been considered to be great just a few short years ago. Although the front and rear calipers appear to be pedestrian sliding calipers with two pistons on the front and a single piston for the rear brakes, the rotors are big. The front rotors measure in at 316mm in diameter and 28mm thick while the rear rotors are 288mm in diameter and 8.5mm thick. The pads are also large for OEM type calipers.

Project VA WRX, Upgrading the Bushings and Swaybars with Superpro Part 1

by Mike Kojima

We decided to be different and tackle the Subaru WRX as our latest Project Car because it's big sister, the STI has been always getting all the attention.  More people can afford the WRX which we consider to be a performance bargain and more enthusiasts drive them.  We will be working with ARK Design to get this car going and make it more fun to drive. 

One of the first things we did as is typical on most of our project cars is to work on the suspension first.   Since we are still deciding on what to do for dampers on our project, we decided to start with changing the soft rubber suspension bushings with some polyurethane parts by Superpro.

MotoIQ Project Gen 3 STi Crawford Performance FMIC front mount intercooler turbosmart clamps Project Gen3 STi - Fueling and Intercooling

by Wes Dumalski

You may have heard the expression 10 lbs of shit in a a 5 lb bag before. Well I am fairly certain the origination of that statement came from the first person to try and remove the intake manifold from an EJ25 and work on the systems surrounding and underneath! In our quest for more power and greater reliability we dive into the bowels (the heart would be the engine) of the boxer motor to upgrade our fuel system, improve the intake and intercooler efficiency and well… To reduce the amount of useless crap tucked in to the engine bay.

by Wes Dumalski

It's single digit temperatures outside and the car is under the knife for a HUGE round of modifications! It doesn't run, we have gotten 14" of snow in the last 48 hours and what are we doing? Why using our daily driver to tow it out of the garage to shoot pictures of our new goodies from Weds Wheels, Progress Suspension, Go Fast Bits, and Kartboy. We risk frost bite to bring you this latest installment of Project Gen3 STi, luckily for you the Internet is warm.

Tested: GrimmSpeed Subaru Top Mount Intercooler

by Wes Dumalski

Around here we appreciate quality and well thought out parts that fill a void in the marketplace. Regardless of company size or the expanse of their market reach it is refreshing to see a company and its collective mindset introduce a product that doesn’t re-invent the wheel but goes a long way to making it much more efficient. In this case that company is GrimmSpeed and that product is their Subaru Top Mount Intercooler.

Project Gen 3 STi: Suspension upgrade with M7

by Wes Dumalski

When last we left off with Project Gen 3 STi we were enjoying the power and up to this point the only modifications we had done so far were to make the car go faster. It was time to change that as the GR STi is a bit soft around the middle. Our friends at M7 came to our rescue with their Super Street Performance Coilover setup. We were eager to put this new suspension through its paces to see what type of performance it really offered so step inside and read all about it.

Global Time Attack Road Atlanta 2013 Doug Wind SRT4

Global Time Attack - Round 1 - Road Atlanta 

By Wes Dumalski 

Quality images by Sarah Forst and mediocre shots by Wes Dumalski 

Attacking time is a funny thing… All sorts of things happen during these 2 day race weekends and no one knows what mother nature or Newton has in store for us. This past weekend at Road Atlanta both of these personas had a chance to show us who's boss and utterly prove that we are in control of very little. In this case the Saturday forecast brought likely promises of rain and when the teams hit the track to sunny skies they were in a fury to set down fast laps as no one knew (not even the weather people; do they ever?) what would unfold. As luck would have it the rain held off and as teams pushed ever further it was Newton who would prevail on this day. Through 11 wins in a row and numerous track records the Professional Awesome EVO VII would turn its last laps in anger, its life cut short by Road Atlanta.

Turn in Concepts TiC X Brace CarLab Development

Tested: TiC WRX Suspension Components 

By Wes Dumalski

Here at MotoIQ we really love our jobs; despite the pay or lack thereof we get the chance to play with some really cool toys, see some really cool cars, and test some cutting edge parts! One of the difficult things we face is having parts we really want to test that do not apply to one of our immediate project cars. When we have those scenarios we are forced to improvise by finding a guinea pig vehicle and having our way with someone else's ride for our own sick pleasure and for the sake of filling this web-site with real world content.  In this case the bovine friendly folks at Turn in Concepts wanted us to put some of their latest products through the proverbial MotoIQ paces and report back with our rants and raves. 

For this test TiC wanted our review on the CarLabs Development X Brace and Super Sexy bushing set for the 02-07 Impreza Sedan platforms.

 Modified StreetCar Shootoout Full Race S14

2013 Modified StreetCar Shootout - The Rules, The Cars, The Big Tease.

By Wes Dumalski and Sarah Forst 

Like all good stories, this one starts on the airplane while on line for the shitter. I hear a voice come up behind me “my GOD this woman won’t shut the hell up”... I turn to fund the animated Bill Caswell and we begin bantering about this woman on the plane who had been talking about absolutely nothing at all for 2 hours. I am on this plane and talking to Bill Caswell because I could not get a refund on my Expedia package and rather than let the tickets go to waste I figured I could still head to Arizona and cover the UMS tuning time attack event and find some good feature cars. As luck would have it two complete car nuts are on the same plane heading to the same place to do the same damn thing; be geeks.

Project Gen 3 STi - Impressions of the Turbosmart IWG75 and BPV

By Wes Dumalski   

"Hey Bro, do you want to test some Turbosmart stuff?" The quoted text is from none other than Martin G from MotoIQ headquarters asking me if I would like to play with any Turbosmart products on our GR STi project. With this project still in the early and mild stages I first scratched my head wondering what I would be able to use and test. When I think Turbosmart I envision huge external wastegates on race cars and e-boost setups. Initially I wondered exactly what I could even use on the STi... Not wanting to miss an opportunity I perused their site and used their vehicle specific search feature to see what they had available.

Project Gen 3STi: Testing the COBB Intake with Some Anti-Bling

By Wes Dumalski

Welcome to WCOB radio... all Cobb Tuning All the time... OK so yeah... the last few installments of Project GR have sounded like the making of a Cobb Tuning radio station! Well quite frankly every time we get the car to a certain point power wise we talk to our friends at Cobb and they tell us we should "try the SF Intake, it's a trick bit of kit and you will love it..." OK so our arms get twisted and we wind up with Cobb's SF Intake and Airbox along with a slew of Cobb goodies to look the part. In this installment we will be testing the SF intake and airbox along with showcasing the e-tune possibilities with the Cobb AccessPORT.
