Project E39 M5: K&N Filters and HPS Intake Hoses

by Martin Gonzales

In this installment of Project BMW E39 M5 we will test two very easy to install intake upgrades- the high flow K&N drop-in filters and HPS Performance Parts silicone intake hose kit. We will be doing individual dyno tests for each part to see if they can free up the S62's intake tract and yield some measurable power gains.

Project C7 Corvette Stingray Z51: Suspension Upgrades

by Mike Kojima

In previous articles about our Project C7 Corvette, we got into the high tech chassis construction of the C7 that rivals the stuff found in exotic cars for a fraction of the price. We also did our baseline testing of the car at Buttonwillow Raceway to get an initial impression of the car. We were quite impressed with the results. In stock form, the Corvette is one of those cars that is so good from the factory that heavy-handed, poorly conceived aftermarket suspension mods can ruin.

Project Sim Racer: Part 4 - Project Cars 2 Review

by Erik Jacobs

Having constructed a quality sim rig and then upgraded it with even better controls, I’ve spent a fair bit of time putting in laps on both iRacing and rFactor 2. A while back, an associate offered to make an introduction to the folks at Slightly Mad Studios, the creator of Project Cars. The introduction came very early in the development cycle of Project Cars 2, but the conversation was fruitful. Not long after the release, I received a copy to review.

Project AP1 S2000: DIY Oil Filter Stopper 

by Vincent Soto

Most S2000 owners know about the oil filter problem on AP1 S2000's. At high RPMS, the engine vibration causes the filter to loosen up (our Project AP1.5 S2000 knows this well, as the F22 swap happened due to this happening on track with the original F20 engine). After a nice Sunday drive, before heading home I decided to check the oil. A gut feeling casued me to check if the filter was tight- which is a good thing that I checked because it was loose. After re-tightening the filter, I was back on my way home- only to find it slightly loose again.

An inside look at the Feal 441 Suspension for the B13 Sentra SE-R!

by Mike Kojima

The original B13 Sentra SE-R has always held a dear spot in many of our hearts. Produced from 1991 to 1994, the SE-R combined the lightweight shell of the Sentra coupe with the sparkling performance of the beloved SR20DE engine. For its time, the SE-R offered a great performance bang for the buck, and to this day, it has scores of hardcore devotees who treasure them.

Project AP1.5 S2000: Introduction, Installation of AEM Infinity & Dyno Tuning!

by Karla Pestotnik

Okay, we know what you might be thinking. We already have two Honda S2000 projects at MotoIQ- why have a third? Plus, this one looks modified already- what else would you do to it that would be interesting? And, why call it an AP1.5? What is that?

Let us address all of these concerns. And, while we are at it, we show you step-by-step how to install an AEM Infinity, how to wire and pin multiple AEM sensors, and show you the results of our dyno tuning. Click to read more!

WATCH: Project V8 RX-7 gets ARP wheel studs, wheel spacers and a new set of nuts!

We were so excited about our new Sikky shifter video that we almost forgot to show you exactly how we approached new lug studs and spacers for the rear. We did a pretty good job guessing what offset would give us that perfect flush fitment of our SSR SP4 wheels on our Rocket Bunny widebody RX-7, but there was still room for improvement! We took care of all that with a set of 10mm FIC spacers, new ARP wheel studs and Muteki lug nuts!

Project F150: Part Three - Center Line Wheels and Nitto Trail Grappler Tires

by S.Tate

We deal with a basic but important set of decisions when selecting wheels and tires for your vehicle. We’ll freely admit that aesthetics are a big part of our choice, but we have other considerations too for this racecar hauler rig. We selected Center Line RT3X wheels and a set of Nitto Trail Grappler M/T tires. In addition, we reprogram our speedometer to accommodate the increase in rolling circumference.

Project Infiniti G37S: Suspension upgrade KW Variant 3s and Eibach Swaybars

by Aaron LaBeau

This is a pretty exciting step for us with this project because we can finally add some good handling characteristics to our car to go, along with the more aggressive wheel and tire setup. Despite all the beefy chassis parts that the G37 shares with the 370z, the G is starting to tip the scales as a bit of a porker and tossing this car into a corner really unsettles this car and the driver. We wanted to get the chassis setup right so that it’s fun to drive aggressively without sacrificing comfort- which is a lot to ask for.

Project C7 Corvette Stingray Z51: Improving Stopping With a Chevy Performance Big Brake Upgrade Kit

by Mike Kojima

When we did our baseline test of Project C7 at Buttonwillow Raceway configuration 13 CW, we were pretty impressed with the stock Z51 Stingray's on-track performance. We felt the chassis was set up pretty well for the wheel and tire configuration that came on the car, and the whole chassis calibration was matched to the amount of tire the stock car had and the power level of the engine.

Project Golf R MKVII: Fluidampr Test

by Isaac Sandoval

The Golf R is back for another round of modifications. Now that we have addressed the suspension and feel the car is handling the way we want it, it is time to move on to the powertrain. We are not entirely sure which direction the powertrain modifications will ultimately go, but the best place to start is by making sure our foundation is solid. In this article, we are going to be installing the Fluidampr crankshaft pulley, as well as doing some baseline Dyno testing on Project Golf R.

Project DC2 Integra: Truing up the Suspension with Whiteline

by Mike Kojima

In the last edition of Project DC2, we greatly improved our car's suspension by replacing the ancient, worn out Koni Yellow shocks with some state of the art street KW Suspension Double Adjustable Variant III coil-overs. When paired with a stock front anti-sway bar and the excellent Comptech rear anti-sway bar that came with the car, we had a well-balanced combination that worked pretty well on the track and the street.  

All was good, but we wanted to go through the entire suspension and replace all of the old and well-worn rubber bushings in the car with new, hard polyurethane parts from Whiteline. This would bring our suspension up to snuff with the current best stuff out there.

Project AP1 S2000: Installing Hasport AP Differential Mounts

by Vincent Soto

Our Project AP1 S2000 is a daily workhorse. It’s almost 17 years old and is coming up on 140,000; the car has been a good reliable daily driver that sees some spirited driving every now and then. 

Recently, we discovered that the differential mounts on Project AP1 S2000 were torn and started to leak. Instead of going back to the OEM liquid filled mounts, we decided to just go with a more solid mount. After driving Project AP2 S2000 and feeling how well the Hasport mounts felt, it was a no brainer to go with them again!

Project GD STI: Making the Front of the Car Stiffer with Ultra Racing

by Mike Kojima

In the last installment of Project STI, we had greatly increased the chassis stiffness with a full complement of Cusco braces. From our EVO project, we had found that on the CT9A chassis, the braces that did the most were the fender braces that add reinforcement from the strong door hinge area to the top of the shock towers. From this experience, we wanted to add similar braces to our STI.

Project Tundra: 5000 Mile Evaluation of Nitto's New Ridge Grappler Tires!

by Mike Kojima

We were very pleased with the Nitto Terra Grappler tires that Project Tundra had been running the last 7 years. We had over 60,000 miles of towing, supercharged burnouts, daily driving and off-roading on them- including a day of driving hard around Willow Springs Raceway. We were very pleased to note that they still had at least 70% of their original tread and still worked quite well!

Project GD STI: Getting Rid of Chassis Flex with Cusco

by Mike Kojima

The GD STI/WRX had what was considered to be a very stiff chassis when it was first released internationally in 2000. The new Impreza platform was built to be much stronger than it predecessor and used much of the experience gleaned in rally competition to build a chassis that was over 100% stiffer than its predecessor. However, that was 17 years ago, and the design that was once the leading edge in unibody chassis integrity is now something that is just average.

Project SR E30: Part 1 - Test Fitting the Engine

by Nikita Rushmanov

So, you built an s13 daily with an SR20 in it. It’s reliable, it’s fast, it makes awesome chu-chu noises, you put 5,000 miles on it, but then you realize that there is one thing this car doesn’t have- 4 doors. That is the exact predicament we were in.
