Project S2000: Part 23. Testing Air Temps Through Coolers and Vents

by Khiem Dinh

Keeping cool is the key to a reliable track car. To add more coolness, I attacked the problem using two methods: adding better heat exchangers and adding airflow. I’ve shown you what the new fluid temperatures have been after the modifications, but what about the actual air temperatures? I added some thermocouples to find out.


 

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.


 

Project S2000: Part 22 – Testing New Goods and More Intake Mods

by Khiem Dinh

The whole point of modifying cars with go-fast parts is to go fast right? So of course, Project S2000 required a good romping at Buttonwillow after the installation of the Blacktrax Performance/Kingpin Machine spherical bearing suspension setup and Hasport rear differential mounts. The car is also in a constant state of tweaking requiring adjustments along the way as lessons are learned. Everything is better with video too and Replay XD stepped in to help.


 

Project S2000: Part 21 - Getting Rid of Squish

by Khiem Dinh

I’m often of the philosophy of replacing things as they wear out. And when they wear out, I might as well upgrade! It all started with a slight banging noise while going over bumps. Over a bit of time, it got progressively worse. Eventually, going over any type of bump including creeping over speed bumps caused a loud banging noise. What was the source?


 

Project S2000: Part 20 - Stock Air Box Modifications And Not Going Faster

by Khiem Dinh

Everyone who has experienced trying to design parts to get more power of the S2000 naturally aspirated can attest to Honda not having left much on the table. Honda was of course limited by pesky general consumer things related to NVH. If you throw those concerns off the table, is there anything to be gained?


 

Project Honda Ruckus - Part One

by Jeff Naeyaert

Enjoy a Throwback Thursday to one of our very first projects!  In typical MotoIQ fashion we decided that our Ruck was going to need some help in the suspension, handling and brakes department before we increased the power to help keep things safe.  We had almost rear ended cars due to weak brakes and ended up doing a flying W by hitting a water dip at 35 mph on the street. Although this sounds somewhat comical, it was not safe and had to be addressed.


 

Plugging and Playing with AEM's Series 2 ECM and B-Series Coil on Plug Kit

by Joe Popovits

In this installment of Project Honda Civic EJ, we tell our factory ECU to take a hike and get engine management fit for this build through AEM's Series 2 Plug and Play EMS.  In addition, we also bring our B18C1 into the new millennium by tossing out the outdated factory ignition system in favor of AEM’s B-Series coil on plug conversion kit.


 

Project S2000: Part 19 - Ram Air!!! Plus Hot Air Testing!

By Khiem Dinh

Did I mention there would be more hood hacking? Why yes I did. Somewhere along the other 18 parts of this project, I noticed the stock air box looked relatively well sealed along with having a location ideal for ram air. Ram air is used on practically every sport bike you can buy to coax as much power as possible from the engine. Even cars such as the Corvette Z06 and Dodge Viper use ram air.


 

Project S2000: DIY Vented Hood

By Khiem Dinh

The destroyer of all track vehicles is excessive heat. Whether it is the coolant, various oils, or brakes, too much heat will lead to failures. On Project S2000, we’ve already addressed the engine coolant and oil temperatures with an upgraded Koyo radiator and Earls Temp-A-Cure oil cooler. These heat exchangers depend on airflow to in order to remove heat from the coolant and oil. No airflow means no cooling, hence the need for fans when the car is sitting still. One way to improve the airflow through the heat exchangers is to minimize the resistance to the air exiting from behind the heat exchangers. For the vast majority of street cars, all the air has to dump out the bottom of the engine bay. So how do we minimize the resistance to airflow? By increasing the area the air has available to exit. In this case, we’re venting the hood.


 

Project Honda Civic EJ: Building the B18C1 Part V

By Chuck Johnson

In our last installment of Project Honda Civic EJ, we thoroughly explored the Harlem Shake phenomenon and also partially completed the assembly of our B18C1’s valvetrain.  Now equipped with Skunk2 valve springs and titanium retainers; the cylinder head of our B18C1 engine is ready for completion.  Next on this list? A set of Pro1+ camshafts, Skunk2 adjustable cam gears, and an ARP stud kit.
