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.
Our E46 M3 is really coming along. In the power department, in order to get significant gains we're pretty much at a point where we either need to get into the motor, or go forced induction. However, a clutch and flywheel is one way we can get more out of the already existing power. In the next two parts we install and dyno test a Clutch Masters FX400 clutch and lightweight flywheel, and show you several other products we used to drop more weight for additional overall performance.
When Cole Powelson set out to build an R35 GT-R he initially didn't have the ambitious plans to build one of the world's fastest time attack cars. The 2012 GT-R originally was built as a modified but streetable time attack car which was run for fun. Then the car was repurposed and underwent a metamorphosis, eventually being rebuilt into the sophisticated machine that appears on our site here.

Radium Engineering's drop-in replacement Fuel Pump Hanger for the Mitsubishi Lancer EVO X is the perfect fuel delivery upgrade for high horsepower applications that use the factory fuel tank but require additional fuel delivery from high-flow aftermarket fuel pumps.
Take a tour of ROUSH Performance and the Roush Automotive Collection before seeing the Stage 3 Mustang in detail. This is supercharged nirvana.
An update for My Girlfriend’s Miata Project has us dipping our toes into the world of aerodynamic performance. I feel as this is an often overlooked aspect of street car performance and another area we shall address as we try to improve all aspects of our Miata platform. We’ll hold off on improving downforce/reducing drag for a future article and instead start with improving reliability through better control of the air for the cooling system.
All cars create blow-by and positive crank case pressure which pumps oil and vapors into the engine’s intake to be burned off for emissions. This problem is worse on forced induction cars and performance cars driven at the track. Not only does this oil gunk up the intake tract and valves, it reduces the octane of your fuel which robs power and causes detonation. We installed a Bob’s Air-Oil Separator to the PCV valve and a catch can for the valve cover vent to see how much oil our Viper’s engine was pumping into the intake after some street and track use.
Extreme Engine Tech: 2JZ-GTE; Part 1 - More Strength, Less Weight
By Pablo Mazlumian
Known as one of the badest blocks that ever left an assembly line, the 2JZ-GTE found in the MKIV Supra is known for its ability to handle horsepower. Unable to contain ourselves, we build one, and make it even stronger. We start by discussing our piston and rod selection. The goal? A streetable 800 whp, daily-driven!
What is burst containment for a turbocharger and why is it important? A turbocharger is a system that has a lot of potential to cause a lot of bad stuff to happen to drivers, spectators, and surrounding equipment. Why might you ask? Well, a typical turbocharger can spin at up to an unfathomable 200,000 rpm for a small frame turbo and a still amazing 90,000 rpm for a large frame turbo! That is a ton of potentially ass-kicking force. We will show you how much later and it's enough to make you cringe.

BorgWarner has added an S400SX-E super core to its successful line of AirWerks® series turbochargers. Featuring an 88-mm inducer Gen-C7 forged milled compressor wheel, this new high-performance unit enables an engine to achieve over 1,575 horsepower per turbocharger. Key features include S500 power potential in a S400 frame size, an integrated speed sensor boss and a 360-degree thrust bearing, which improves thrust capability and extends turbocharger life.
Rally cars are awesome. They are small, nimble, and pack a lot of horsepower to roast four tires worth of carbon into some smoky state between solid and gas. Most rally cars are built to a pretty common formula for rally cars based on a strict set of rules. There’s also a lot of heritage that goes along with rally racing. But what if you raced where the rules were more open? What would you do?
The last time we saw the Nissan Juke Multi-Purpose Racer Opy, Opy had some fun competing at a hill climb event. However, Opy ran into some over-heating issues and Lars started working on upgrades. It was time to put in more equipment to put some more ‘Racer’ into the Multi-Purpose Racer too.
There’s an old adage that nothing good comes out of a sequence of events starting with “Hey y’all, watch this!” In the case of Bill and Billy Wagner, what started with a friend’s sideways remark of “Wow, that’s a big motor. How fast will it go?” turned into a world-record setting 232.8 MPH Shelby GT500 Mustang. Maybe that old adage is wrong.
