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.

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.

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.

turbosmart BPV subaru STi impreza

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 GD STI- Getting it Slowed Down with Stoptech

By Mike Kojima

The Subaru GD STI comes with pretty good brakes from the factory, big Brembo 4 piston front and 2 piston rear calipers squeeze big vented rotors. In other words the stock brakes are already quite good, what would have been state of the art just a few years ago. This means we would have to be careful when it comes to modding them, it is easy to mess things up and actually do worse than stock with a poorly engineered brake upgrade.  So why would we want to change them out with something else?  The main reason is that since our car is going to see some occasional track use, we want to upgrade our brakes so we can drive our car to the track for an event without the hassle of having to switch pads at the track.  The big brakes will allow us to run at speed on a streetable brake pad.  Bigger more powerful brakes will also be easier to modulate. The third reason is admittedly that big brakes just plain look cool! We went with Stoptech as the brake system of choice for their combination of daily driveability and track performance.  We selected Stoptech's Trophy STR big brake kit.

Cobb SF intake Subaru STi MotoIQ dyno test

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.

Project GD STI- Keeping Cool with Greddy and Koyo!

By Mike Kojima

At this stage in the modding of Project STI's engine, it is time for us to lay down some base parts to support our plans for more power later.  One of the weak points of the Subaru intake tract is its top mount intercooler or interheater as some call it.  It is pretty ineffective at cooling the charge air as it sits in a heat chimney right over the engine.  It is fed by a large scoop but air only flows through it at speed.  This makes for irregular intercooler effectiveness.  The top mount intercooler is a legacy of the car's rally heritage where the Subaru engineers wanted to move the intercooler out of harms way.  Interestingly enough the last generations of Subaru's WRC car had front mounts.

Project GD STI- Keeping Cool and Protected with 3M Crystalline Tint and Protective Film

By Mike Kojima

Project GD STI is a daily driver that we put a lot of miles on, from driving to our daily appointments, to the office and to the track on the weekends. Just in case you didnt know this, Southern California is a hot area, desert really, with a lot of sun exposure and all tracks around here are in the pit of the earth, really in the desert!

Project GD Subaru STI Part Three- Making More Power with Greddy and Cobb Tuning

By Mike Kojima

When we last left off, we had turned our STI into a G machine without giving up much daily driving comfort.  Now it was time for us to turn our attention to the engine.  The GD STI really responds to very basic tuning.

Project GD Subaru STI Part Two- Performance Suspension, Wheels and Tires

By Mike Kojima

In the last installment of Project GD Subaru STI, we set about replacing our car's worn out bushings, ball joints and tie rods with some trick stuff from Whiteline.  We also reduced the anti geometry in our front suspension and raised our front roll center while making everything fully camber adjustable.  For this edition we will finish our suspension by adding some high performance KW Clubsport coilovers, some chassis reinforcement and some Advan wheels with sticky Falken 615K tires.
