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.

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!

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 EP3 Civic Si: Fixing the @$#%! Steering for Good with SHG Motor Works!

by Mike Kojima

In our last edition of Project EP3 Civic Si, we thought we had fixed our car's bump steer and wandering steering with a roll center correction kit and a bump steer kit from Hardrace. Our car had serious issues since day one. When we first got it, no one wanted to drive it because the car would wander around on the freeway and everyone was afraid of getting pulled over for drunk driving.

So, we installed a bunch of suspension stuff and finished it with the Hardrace geometry correcting parts in the front suspension. With the car finally handling well, which is no small task with an EP3, we were finally having fun driving it hard. All was good for a couple of weeks, but then the wandering steering returned with a vengeance.

Project AP1 S2000: Installing Forbidden Side Diffusers

by Karla Pestotnik

Project AP1 S2000 has specific plans to be the ultimate, fun street car that can hold its own performance-wise, without losing its street-ability factor by turning into a full-blown racecar or track dedicated car. However, what is a good handling street car without its good looks? We clean up the S2000's rocker panels with a set of Forbidden USA's carbon fiber side diffusers.

Project EP3 Civic Si: Fixing EP3 Bumpsteer with Hardrace

by Mike Kojima

In prior editions of Project EP3 Civic Si, we went over the history of the car- the worst handling Civic made with suspension geometry taken right from the Stream minivan. Well, so far we have gotten rid of squishy rubber and added sway bars with help from Whiteline. We also got rid of the flaccid shocks with a set of coilovers from Fortune Auto. Now we will address bumpsteer issues with Hardrace!

Project EP3 Civic Si: Installing Fortune Auto 510 Coilovers!

by Mike Kojima

Over the past few installments of our EP3 project, we have been working on fixing on what is perhaps the car's major weak point, the handling. Previous Civics were known for excellent handling with 4-wheel multi-link suspension. The EP3 however, uses the suspension from a Japanese market Stream van in a really dumb case of parts bin engineering.

Project EP3 Civic Si, Suspension Upgrades with Whiteline! 

by Mike Kojima

So everyone into Hondas just about universally ignores or even hates the dumpy EP3 Civic. The EP3 represents, to most Honda fans the generation of Civic where Honda lost their brand identity and started to make cookie cutter shitboxes.

Project EP3 Si: Going 5 Lug with Wheels from Enkei and Nitto NT05 Tires

by Mike Kojima

Now that we converted our EP3 Civic from 4 to 5 lug hubs and added big brakes, there was no going back.  In order to drive the car, we obviously needed to do something about our wheel situation.  Our goal was to stuff the biggest tires we could into the stock wheel wells.  Unlike our hellaflush brethren, we want big and we want traction, not stretching a narrow tire on a wide rim and stupid amounts of negative camber.

Project EP3 Civic Si, Improving the Brakes with Fastbrakes, Stoptech and Willwood

by Mike Kojima

In the last edition of Project EP3 Civic Si, we explained how we went about converting our car from 4 lug to 5 lug hubs. We did this for two reasons: one to take advantage of the larger selection of 4x114.3 bolt circle wheels available on the market and to take advantage of the larger RSX Type-S wheel bearings and axles to stiffen up the bearing system in anticipation of performance fixed caliper brakes and more power from a possible engine swap.

Testing Meguiar's Two Step Headlight Restoration Kit!

by Mike Kojima

Any car that has the newer plastic headlights will experience weathering and yellowing eventually. This is caused by UV light exposure degrading the protective coating on the surface of the lights. Once the coating is eroded, UV light makes quick work of the clear plastic underneath, and the light becomes cloudy and yellow.

How To Do A 5 Lug Conversion the Right Way! Project EP3

by Mike Kojima

As we finally start to mod our much-maligned shop EP3, the car that everyone loves to hate, we came to the realization that the car had pretty big wheel wells. To us, big wheel wells does not mean room for offset, slammed to the ground ride height or dumb camber but room for big grippy tires!

Building the Naturally Aspirated Honda K Engine Part 3, Assembling the Engine

by Mike Kojima

In the previous two installments of our engine build, you were able to take a look at the parts we will be using to build the bottom end and the cylinder head of our Ariel Atom. Notably, we went with a Dailey Engineering dry-sump system, since the Atom has a lot of aero-enhanced grip, and we want to avoid oil starvation.

Project DC2 Integra - Fixing Old Clutch Woes With Centerforce

by Mike Kojima

Our DC2 Integra was a great find, in near unmolested close to stock condition despite being a GSR and being over 20 years old. Most DC2's of this era have either been mauled by a few generations of ricers, stolen several times or kept as treasured garage queens behind locked gates only to be driven to meets or other special occasions.

Project S2000: Part 24 - Bridgestone Potenza RE-71Rs and DIY Brake Ducts

by Khiem Dinh

In the last episode, I’d worn down the Nitto NT01 tires into slicks. Then I got a nail in one of the tires too. Obviously, it was time to get some new tires. Many of you have asked about my custom brake ducts which bolt to the front lower control arm. Well, I tried out a cheap DIY version along with finally getting around to making some rear brake ducts.

Plastic is Fantastic:  Part 6 – Assembling the Beast

by Jonathan Spiegel

As usual, racecars rarely get finished on schedule when you’ve got a day job, but that hasn’t stopped us from burning up weekends (and a little midnight oil on weeknights as well). When we last looked at the Polystrand CRX GT-Lite car, we had just finished creating the new rear framework for the trick IRS assembly. For those of you who haven’t been following the project so far, you can click here to catch up on the first 5 installments of this crazy journey. Without much fanfare, we’re going to jump right back in, since we’ve made a lot of progress since then.

Project Civic EF Racecar: Part 4 - Improving Cooling Efficiency with Earl's Performance

by Clint Boisdeau

It's been a while since Project Civic EF Racecar has had an update outside of the MotoIQ Pacific Tuner Car Championship race coverage articles.  So here we'll take a closer look at the oil cooler upgrade thanks to Earl's Performance.  The oil cooler setup which came with Project EF worked fine, but had some room to improve in regards to overall performance with the core, and durability with the lines.  With the heat and abuse a wheel-to-wheel race car can put into the engine oil during 30 minute sprint races, having a cooler configuration with high levels of effectiveness is critical.  Also essential is having lines sized correctly for proper flow and oil pressure.

Project Bucket: EP3 Honda Civic Si

by Mike Kojima

What, I said, your brother in law wants to sell his Civic Si for $500?  I was speaking to one of my friends who thought I might be interested in this deal.  What's wrong with it? Does it run? Has it been wrecked?  Is it stolen?  No, my friend said, it's in great shape and runs fine with about 100k miles on it.  Everything works, he just doesn't want it anymore.  What's the catch? I asked. I dunno said my friend, it's a 2003 Si.

Project Honda Civic EJ Finale: Dyno Results and Lap Times

by Chuck Johnson

Back in 2011, we introduced Project Honda Civic EJ to the readers of MotoIQ.  Originally, the goal of the project was to take Annie’s beat down 1997 Honda Civic with over 260,000 miles on it and restore it back to the formidable yet reliable street and track machine it once was.  All this, while keeping to a reasonable budget. However, what could only be described as massive scope creep ensued. Now four years later, Project Honda Civic EJ has finally come to an end... or to a new beginning?
