TESTED: Achilles Tire R1-X

By Steve Rockwood

I've driven on a lot of tires, some of them horrible, some of them great. All of them have been DOT legal. Until now. When we were approached by Achilles Tire to try out their new R1-X racing slick on Project G20 Racecar, we predictably jumped at the opportunity.

Project Honda Civic EJ: Building the B18C1 Part V

By Chuck Johnson

In our last installment of Project Honda Civic EJ, we thoroughly explored the Harlem Shake phenomenon and also partially completed the assembly of our B18C1’s valvetrain.  Now equipped with Skunk2 valve springs and titanium retainers; the cylinder head of our B18C1 engine is ready for completion.  Next on this list? A set of Pro1+ camshafts, Skunk2 adjustable cam gears, and an ARP stud kit. 

The Project Evo X MR is back!

By Cheston Chiu

Just when you thought all was lost, the MotoIQ Project Evo X MR is back on track.
As previously stated back in the November 2011 article Project Evo X GSR - Testing the K&N Cold Air Intake.  "The owner", aka. ME, was fairly reluctant to venture beyond simple engine bolt-ons mainly due to concerns with the twin-clutch SST transmission and its ability to hold power.  The other excuse, which I think would supersede anything else, was the fact that the project stalled because my wife and I were trying raise our one-year old daughter at the time.  All we did was go to work and then come home to take care of her (and the dog)—which didn't allow a whole lot of time for hobbies.  Now, let's fast forward to today, I have a little bit more free time since Mike wrote that article, my daughter is getting easier to manage, and during the hiatus I've stockpiled a bunch of awesome parts that I'd like to chronicle for MotoIQ.

Project Car Update:  The V8 Edition

By Colin Holte

A quick glance at the project car column should tell you that MotoIQ has a large (and ever expanding) roster of project vehicles.  With all these vehicles it can sometimes be tough to keep the updates flowing for each.  In some cases vehicles may have even been sold but we still keep them on the project roll for posterity.  These articles are intended to share a little bit of the details with you of where some of the project vehicles that haven't seen the spotlight in a while are at in their evolution.  In this installment we check in with the V8s:  Project Mustang V8 5.0, Project Tundra, Project V8 RX-7, and Project Lexus IS F.

Project Honda Civic EJ Gets a Full Body Makeover

By Annie Sam

What was supposed to have only been a simple six month project to boost Project EJ Civic's performance with basic bolt-on applications has turned into a two year journey down the long, long rabbit hole. Fast forward two years, and the light we were wondering if we would ever see finally manifested itself at the end of the proverbial tunnel. Project Honda Civic EJ was finally turning the corner to focus more on finishing the build. But then again… as any gearhead would question, are you really ever finished?

Project Supra Part 5: Thermal Coating, Wrapping, and Engine Assembly

by Pablo Mazlumian

A notable tradeoff to turbocharged power is the potential for more heat in the engine bay, leading to less-than-optimal power and increased turbo lag.  Find out how we minimize these fun-killers.  Our cylinder head and built short block also come together, and we show off the variety of MKC-tuned boosted cars.

Project 240SX Land Speed Racer:  Flat Out on the Bonneville Salt Flats (Video)

By Chuck Johnson

It’s really easy for people to discredit going fast in a straight line.  Hell, I myself have been guilty of snickering at the thought of "run what you brung" night at the drag races.  I mean how much skill could it really take to hold a steering wheel straight and mash on the throttle for a ¼ mile?  The truth is though, it doesn’t matter if it’s driving in a straight line or around the same damn circle for hours.

Project 370Z - Improving Grip by Tuning a Cusco RS LSD!

By Mike Kojima

So far with our Project 370Z we have been focused on dialing in the chassis.  After some track time, it has become apparent that the rear differential is the next handicap in achieving faster lap times.  Although the Z has a viscous limited slip diff from the factory,  our testing has found it to be highly inadequate.  In fact it is hardly a limited slip diff at all, allowing a lot of inside rear wheel spin, even out of medium speed corners.  In some street tire testing at Buttonwillow our lap time was being limited to the low 2:06 range for configuration 13CW.

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.
