Engine Downsizing and Turbos: More MPG and More Power?!

By Khiem Dinh

In an extremely rare instance, government regulations have actually made two seemingly conflicting goals both better.  "To have one's cake and eat it too" as they would say.  With rising fuel costs and environmental concerns, regulatory bodies across the world are demanding reduced fuel consumption and lower emissions.  Previously, this would imply smaller engines with reduced horsepower; two things counter to the wants of performance enthusiasts.  Enter the modern turbocharged engine.  Through turbocharging, engines can now deliver a wider torque curve, more power, and substantially improved fuel economy.  The fuel economy gains are through engine downsizing and downspeeding.  We're going to show you how turbos achieve all of these goals.

Demystifying the Camshaft: Part 2 – Terminology

by Jonathan Spiegel

In the first installment of this series, we took a fairly in-depth look at valve events, which, simply put, are the actions that are caused by the camshaft with regards to opening and closing the intake and exhaust valves. Ultimately, these events determine the power characteristics of an engine, because they control the amount of air/fuel mixture that the engine ingests at any given rpm, and they also control the flow of exhaust gases leaving the combustion chamber. Hopefully, Part 1 helped you to understand the processes involved in developing a camshaft design, so at this point we’re going to discuss the terminology that directly describes the physical parameters of the camshaft itself.

Squirrel Power: Saving a Suzuki FA50

by David Zipf

You may remember when we were battling the power steering in our Project VehiCross, that the biggest reason we got so hosed (no pun intended) was I had no way of getting myself to the parts store for things like crush washers, coolant, or big buckets.  With only one functioning car, we needed something else to get us around when we were wrenching on our daily driver.  See how we rescued and resurrected a forgotten scooter that hadn't turned a wheel in over a decade.

Wrench Tip: Get a Jewelry Cleaner

by David Zipf

Cleaning small parts can be a real hassle.  If you’re rebuilding, say, a carburetor, with lots of little jets, needles, and pins and screws, it can be very easy to break or lose something.  Some parts refuse to come clean, even when scrubbed with strong solvents (brake calipers are a great example of this).  So what’s a car guy to do?

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.

Keep It Simple - Go Tuning's Spoon Sports Civic

by Mike Kojima

What's the best thing to do to re launch a performance brand in the USA?  Go racing. That is exactly what Go Tuning, the official North American distributor of Spoon Sports parts has done in the world of Time Attack in a big way.  In practice for the last Super Lap Battle, Dai Yoshihara, previous Formula D and MPTCC Champ peddled Go Tuning's Spoon Sport Civic to a blistering 1:46.3 second lap time around Buttonwillow's famed configuration 13 CW. This was faster than Chris Rado's long standing FWD Unlimited lap record in the high tech 1300hp F-Wing Scion TC, a record we assumed would be out of reach for a long, long time.

Extreme Engine Tech: Building the Ultimate K24 Part 1 The Cylinder Head!

by Mike Kojima

Modding late model Honda/Acura engines is somewhat problematic lately.  Take for instance the late model K series engine.  Once probably the best naturally aspirated inline four cylinder production engine by far, the K motor in it's latest variant, the K24Z7, is a neutered, decontented version of its former self.  Found in the current 2012 and up Honda Civic Si and the Acura ILX, the K24Z7 still boasts a decent 205 hp and 174 lb ft of torque. This is slightly better power and much better torque than the much acclaimed bone stock K20A2 that everyone knows and loves.

Can the late model K motor be saved?  We will give it a shot with help from the guys at Motovicity Distribution!

How to PROPERLY select and size TIRES for PERFORMANCE

by Billy Johnson

The most important part of your car is not the engine, suspension, or brakes. It’s the TIRES!!!  This is because your car can only perform as well as the capability of its tires. I’m often asked which tire is best and what size to buy.  In this article I discuss my methods for choosing and properly sizing the right tires.  I’m not into the “hella-flush” or “stance” scenes so this article is focused towards those who care about the PERFORMANCE of their car, whether on the street or on the track.

Snowpocalypse: Winterizing Your Car the Right Way

by David Zipf

As the holiday music fills the air on every freakin' street corner in the United States, the weather begins to turn cold and the populace begins to cower in fear of the dreaded flakes of solidified water that fall from the atmosphere.  If you’re like most of the MotoIQ staff, you live in southern California where you have to drive hours to find a hint of the fluffy white stuff.  Not all of us are so lucky unfortunately, and if you live in the northern part of the world, you will at some point have to deal with snow.  And since we live in the age of the internet, there is tons of advice out there on how to prepare for winter, some of it good, some of it questionable, some of it horrible.  So let’s do what MotoIQ does best and cut the crap and help you prepare for the winter the right way.

Project VA WRX: Improving the Suspension With Tein Flex-Z Coilovers

by Mike Kojima

Many of our MotoIQ Project Cars feature top of the line or even exotic suspension parts, exactly the kind of stuff you want to use in cars that see mixed track/street use with a heavy track bias. However, not all of our cars are set up like this, some of our cars are more street oriented and set up towards hassle free daily use.

Project Isuzu VehiCross: Part 5 - Bodywork Round 1

by David Zipf

With four project installments of our Project VehiCross, you would expect we would have done something insane to it.  After all most MotoIQ projects don’t stay stock very long and so far the only aftermarket parts this truck has seen are an air filterbrake pads, and tires.  After ranting and raving about how terrible replacing a power steering hose on a VehiCross is, we promised we would start putting on some sweet aftermarket parts.  We lied.

Wrench Tip: How To Remove a Bolt From Plastic

by David Zipf

I had the recent displeasure of being rear-ended in the Vehicross.  Luckily, the accident wasn't too bad (and we will get into it more in a later project installment), but the bumper cover did need to be replaced.  We decided to replace our damaged bumper with a used one.  The used bumper was in good shape, but we found a number of the mounting bolts were rusted onto what was left of the bumper support.  We would have to remove these bolts without damaging the new cover.  This would require a delicate mix of power tools, cleverness, and a basic understanding of heat transfer.

When TEIN released the EDFC controller nearly 14 years ago, the suspension tuning world hit a new level of technology. Now with its more current EDFC ACTIVE version, TEIN has stepped up its game again, and we got to install it on our 800 WHP Project MKIV Supra!
