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.


 

Project Viper GTS Part 4 Intro

Project Viper GTS: Part 4 – Baseline Dyno and K&N Intake Test

by Billy Johnson

The Viper is truly a car built around its engine.  In Part 4, we take Project Viper GTS to the dyno for a baseline power audit and see if our mighty 8.0L V10 is cranking out the factory claimed 450hp and 490lb-ft of torque.  From there we add K&N replacement air filters and change out the disruptive corrugated plastic intake tubing for a set of ROE Racing polished aluminum smooth intake tubes to see if we can squeeze out a few more ponies.


 

Project Mazda3: Part 3 - Improving our Contact Patch

by Per Schroeder

Now that Spring has sprung here in the Mid-World, it’s time to get our 2014 Mazda3 ready for some autocross fun.  We are planning on competing in SCCA’s Street Touring F category against MINI Coopers, Acura RSXs and Mazda2s, as well as other Mazda3s.


 

Project [Rotary] FD RX-7: Part 5 - Cooling Oil and Generating Spark

by M-P Spierer

Whether it's high RPM, high power density, or for some, high failure rate, the word "high" is regularly used to describe various attributes of the rotary engine.  Today we are fighting against the rotary engine's high inclination for dangerous oil temperatures and ignition break-up. This requires significant upgrades to both the oil cooling system and the ignition system...and by upgrades, we of course mean complete redesign.


 

Project E46 M3: Part 11 – Castro Motorsports Intake Manifold Installed and Dyno Tested!

by Pablo Mazlumian

We install and test the Castro Motorsport CSL-style airbox on the dyno with video clips of the new sounds.  We also get to check out a couple more of Modified by KC's projects, including one of the baddest BMW 335s in the country!


 

Project Mustang 5.0: Part 9 – Brake Overhaul with Hawk Performance and Disc Brakes Australia

by Vince Illi

You use your brakes a lot.  But do you really know how they work?  We test out Hawk Performance’s new HPS 5.0 pads and DBA’s 4000-series rotors and examine how brake pads and discs work together to stop your car!


 

Project Ford Fiesta ST- Making the Jump to a Race Car with SPD Motorsports Part 2!

by Mike Kojima

When we last left our Project Ford Fiesta ST it was being converted into a race car by the capable hands of SPD Motorsports.  As progress continues, SPD  is working on installing a crash resistant fuel system using components from Fuel Safe, Deatschwerks, and Aeromotive. Other details like Lexan windows, brake ducting and the interior are coming together as well.


 

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.


 

Track Life: Episode 1 - How to Prep Your Car for the Track

by GTChannel

Thinking about going racing this weekend? Karla Pestotnik and Rob Choo use the GTChannel S2000 to show you step-by-step how to change your differential oil, motor oil and transmission oil, as well as how to bleed your brakes and clutch fluid.


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.
