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 EP3 Civic Si: Can an Oil Change Affect Horsepower?

by Mike Kojima

A lot of people have asked this question before, and the jury has been out on whether this is something that is true or not. We have attempted to test to see whether certain brands of high-quality oil have a gain in power over others before with mixed results. Our dyno tests have always been inconclusive with the differences being too small to be considered or perhaps caused by variables such as differences in viscosity or sump level.

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!

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.

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.

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.


 

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

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!

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.
