Polystrand GT-Lite CRX: Part 4 - Bringing the Design Concept to Life!

by Jonathan Spiegel

As we left off in the previous installment, we’d completed our prototype suspension design, done some analysis on the springs and arms, and sent the dissected chassis off to the body shop to get some much needed love. Now comes the part that is almost as much fun as driving – bringing the design concept to life!

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!

Extreme Engine Tech: Building a BMW S52 – Part 1: The Short Block

by Nick Betz

There comes a time in a project build when you just have to throw everything out the window and rewrite your storyboard. Over the years we’ve been bolting on parts to Project E36 323is and not seeing the gains we were looking for. Sure it’s been fun but it’s time to make some real power. We had plans for an M50 manifold swap paired with M3 cams, bigger air meter, headers and throttle body but as the old adage goes, there’s no replacement for displacement, so that’s where our journey has taken us.

Lessons in Turbo Technology with Garrett!  Lesson 1 - The Compressor Wheel

by Mike Kojima

Recently we were privileged to be able to take a look behind the walls of Garrett Turbochargers' research and development facilities.  We were able to get an insider view of the intensive engineering inside a Garrett Turbo and viewed first hand what differentiates it from your typical aftermarket fare.  We were very impressed by what we saw and we would like to share it with you by breaking some of what a World Class OEM supplier puts into the performance turbos any consumer can buy into easily digestible lessons that we will be presenting to you periodically. Perhaps the key part of any turbo is the compressor wheel.  Let's look at what Garrett does to bring you one of the best compressor wheels on the market.

GTA Road Atlanta: #teamcanada is Coming

by Frank Ewald

Canadians are known for their love of hockey. We are known for having a Tim Horton’s Coffee shop on every other corner of some cities.  We are known for putting the letter ‘u’ in words like neighbour and colour and doughnuts. We are known for being the small country above the United States of America – your northern neighbour with a much larger land mass yet a drastically smaller population. We are known around the world for being a country of polite and respectful people – accepted around the world in more places than American Express. Canadians are known for great Time Attack builds and drivers – whoa, you say! Things were going okay until that bit about Time Attack!

Extreme Engine Tech: Technosquare's Monster Naturally Aspirated Toyota 4AG - Part 2

Extreme Engine Tech: Technosquare's Monster Naturally Aspirated Toyota 4AG - Part 2

by Mike Kojima

In our last edition of the building of Technosquare's monster Toyota 4AG, we mainly looked at the details of the bottom end.  Now we will finish our tour of the bottom end and delve into the engine's cylinder head which is the heart of any high performance engine.

The 83mm x 83 mm stroker motor gives 1800cc.  The 200 extra cc's makes a huge difference, fortifying the 4AG's notoriously narrow power band. The engine cranks out over 250 crank hp, more than the most highly developed Formula Atlantic engines of yore and 30 more hp than the previous 1600 cc version of this motor. Here it is, re released again for your reading pleasure!

Project Tundra: Leveling it out with a Hellwig Big Wig Air Lift

by Mike Kojima

In the last edition of Project Tundra, we had installed Hellwig's adjustable rear antisway bar in an effort to improve our truck's balance and limit body body roll to help keep our stability control from activating prematurely. 

Now to finish up our chassis tuning we wanted to address a problem all trucks that tow have. With tongue weight in place the back of a trucks sags lower and the front lifts higher.  This makes the handling a little squirrely at times, the steering getting light a lot due to the geometry changes of the front end when under droop. The heavily loaded rear suspension is also prone to bottom out with bigger enclosed trailers which can make things interesting and possibly damage the trailer jack.

To fix this by leveling out our truck without hurting our ride, we decided to go with a set of Hellwig Big Wig air bags.  The air bags can increase the rear suspension's capacity by 2700 lbs and restore the proper ride height improving stability and laden ride.  When finished towing, the bags can be depressurized for a stock ride height. and smooth ride.

Technosquare Howard Watanabe 4AG Engine Build

Extreme Engine Tech:  Technosquare's Monster Naturally Aspirated Toyota 4AG - Part I

by Mike Kojima

The Toyota 4AG is a historic engine, one that was essential in launching sport compact car culture in the USA.  In 1985 the 4AG first rocked the automotive world.  It was the standard engine in the Toyota Corolla GTS, the famed Hachi Roku AE86.  The AE86 was the last of the RWD Corollas and Toyota made history by equipping it with the revolutionary 4AG engine.  Not to be forgotten, the AW11 MR2 mid engine sports car was also powered by the 4AG.

Turbo Tech: Size Matters! - Part 2

by Khiem Dinh

In Part 1 of Size Matters, we went over the basic concept of sizing the turbo for the application and desired torque curve shape to match the intended use of the vehicle. You know, because a couple million people a year ask what size turbo they should get for their _______ (insert application here, i.e. car, motorcycle, boat, scooter, lawn mower, etc). Once everyone gets a bit more turbo savvy, they learn of the concept of boost from a small turbo does not equal boost of a big turbo. Well, we’re going to explain why.

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.

Project Tundra, Getting More Cornering Power (and less stability control activation) with a Hellwig Adjustable Rear Antisway Bar

by Mike Kojima

If you have been following Project Tundra, you know we have been struggling with excessive activation of our truck's stability and traction control systems.  The improved power of our supercharged engine and additional traction of our larger tires have been driving the electronic nannys of the truck's OEM systems crazy.  We were hopeful that a new adjustable rear antisway bar from Hellwig would help.

Evaluating the HKS Max IV SP S2000 Coilover Suspension System

by Mike Kojima

The guys at Motovicity have been singing the praises of HKS's new Max IV coilover systems to us for a while.  While we have generally always been impressed with HKS's tidy OEM like engineering, it was a while since we had experienced their coilovers.  In the early 2000's we had tried some of the original Hipermax suspensions on a few of our cars and although we found them to be of high quality and smooth riding, they did not have enough spring rate and damping for serious performance with big sticky tires and especially track use.  We sort of regulated the brand as nice for street use only and looked toward other places for suspension for our projects.

Fast forward 10 years and 4 generations of Hipermax suspension later, plus Motovicity's raving about them made us eager to get our hands on the Hipermax or Max 4 suspension system for another review.
