Today I didn’t have a lot of time to work so I focused on removing the motor and placing it on the stand.

I finally had the time to start this weekend. The tear down is always the easy part. As you can see below, the chassis is a little rough around the edges but I will be fixing all of that in the weeks to come. Most of the items have been removed form the engine bay and I began gutting the interior.
This mod is the first step in a progression of mods that will ultimately result in the fabrication of a fully custom cold air intake on the MR2 Spyder. The factory intake makes a 90 degree bend after the throttle body and attaches to an intake box. After the box, a long, 2 piece set of plastic tubing snakes around the driver’s side rear fender well and attaches to a hole just behind the...
Recently project S2000 has enjoyed the addition of a Comptech supercharger to give it a little more … ooomph. But even with the stage 1 pulley peaking at a paltry 5psi, it became clear rather early that the Comptech system is very prone to heat soak. Being daily driven in Tennessee means that this car needs to handle summer temps that touch 100 degrees F. With this year’s mild winter...
The oil pressure gauge installed on project S2000 is a Faze electrical unit. This guide will demonstrate how to install the sending unit and assumes that the actual gauge itself is already wired for power. (If you need help with the wiring, refer to the previous install (Honda S2000 Boost Gauge Install) as it details the wiring of an electric gauge.) Getting Started An electric gauge will come...
The lower rear braces for the MR2 Spyder are member braces that triangulate the control arms on each side of the rear suspension. These braces connect the frame mounting points of the arms together, effectively reducing the flex under corning and acceleration. As a result, the rear end will feel more stable. However, by increasing the rigidity of the rear, the car will also tend to oversteer more...
From the factory, the front of the MR2 Spyder has two braces that connect the frame rail on each side to the front cross member on the under side of the car. These two braces (or bars) reduce the flex in the front of the chassis in a fore and aft direction. However, this is one particular area on the chassis that could really benefit from lateral bracing so in comes Che’s Front Lower Brace...
A boost gauge is an absolute must on any boosted vehicle. On a turbo charged car it will tell you not only how much boost is being developed but whether or not the boost is spiking, creeping or overrunning the wastegate. All of which are important to the longevity of the motor. On a supercharged car however, boost is typically a fixed value dictated by the size of the pulley. Even so, a boost...
To complement project S2000’s newly pressurized intake manifold, the addition of a few aftermarket gauges are being added to help keep tabs on the motor. But first, a place is needed to locate the first two gauges so in comes the pillar mounted gauge pod. The pod chosen is made specifically for the Honda S2000 and replaces the factory driver’s side pillar. (Note: This procedure is...
The TRD front strut tower brace for the MR2 Spyder is a 5.2 lb, dual tube strut bar that reduces the front chassis flex during cornering. I have had strut tower braces installed on most cars I have owned and more often than not, only minimal suspension gains are found. However, the TRD strut brace on the MR2 is truly a gem and really increases the the feedback to the driver while improving...
Purpose: Consider the fuel pump the heart of the fuel system. It provides a constant supply of fuel to the fuel rail to ensure that the injectors always have enough fuel to work with. However, when the power output is significantly increased over stock the motor becomes hungrier and the injectors need more fuel to maintain proper air fuel ratios. (This is especially true under boost.) An upgraded...
The following guide walks through the steps that were taken to install the Comptech stage 1 centrifugal supercharger onto project S2000. The “complete” kit came off of another Honda S2000 that was getting traded for a 350Z. As this was a used kit we did not have directions for the install and suspect that an extra bracket was missing. As such, this tutorial covers the steps we took to...
