James’s CN9A Build… Part 1

The Mitsubishi Evolution is one of the more favored AWD platforms locally and today we’ll be diving into a few of the parts James has accumulated since regaining ownership of the car. James always had big plans in store from his initial cross over to the AWD platform,  unfortunately these plans were short lived at the time. Having separated himself from the scene somewhat, James has returned with a new energy in hopes of producing what in his eyes would be the ultimate all purpose Evolution. In the previous posted we touched on the plans James has for the Evo to attend track days, take in some drag racing and he also intends on street driving the car heavily with comfort being one of his main focal points.

Even though the car was already equipped to be a very fun street driven car, there were a few specific things James wanted to tweak. The sole purpose of this would be to bring the car to a level at which it can not only be reliable, but also competitive and consistent when he does take it to the track for either 1/8 mile events or track days.

 

For those who may be viewing this build for the first time, I’ve provided the link to the previous posts below:-

James’s CN9A Build… Introduction

Upon having the car back in his possession James had a few items he wanted to take care of, first was to replace the factory corner lights. On a mission to find OE spec orange corners for the car, James went as far as to source a set out of Japan; and wasted no time in fitting them upon arrival…

James didn’t stop at the corner lights, he also thought it was necessary to change out the dated factory headlight units…

When thinking about going faster with the CN9A chassis, James also factored in how he would be able to slow down. With a plan in mind, he went ahead and upgraded the braking system to the Evo VII Brembo setup all around…

Still being very much on a budget, he opted to pick up a set of Evo VIII Enkei wheels locally and had them wrapped in Falken Azenis RT615K rubber in a 215/45/17 sizing…

In doing the conversion to the Evo VII calipers, James picked up a fresh set of Hawk HPS pads to go with a full set of aftermarket rotors…

Not satisfied as yet and with plans to take in some track day action with the build, he opted to get some FTP steel braided lines for each corner that would allow him to be more consistent with his braking while on the track…

James is a big fan of the OEM spec interior that Mitsubishi provided from the factory; so when it was time to purchase another steering wheel, he opted to go with the factory Momo wheel which gives a sporty feel while retaining the use of the airbag…

In the name of performance, James chose relocated the battery to have some more space in the bay that would accommodate for the use of a  better intake system…

One of the main components of this conversion is having the correct wire necessary to extend the length of the car…

James wanted to ensure everything on the underside of the Evo IV was in top working order and would be up for the tasks ahead. He placed an order for all the necessary bushings that would tighten up the handling characteristics of the CN9A chassis…

Along with the bushings he also replaced all the ball joints and worn steering components…

 

Moving forward with the motor related plans for the build…

IMG_20200216_142202

James knew he needed to make some changes to the cooling system given his intentions of increasing power. He was able to pick up a custom built intercooler locally…

IMG_20200216_142148

IMG_20200216_142227

This featured a 4″ Garrett core and custom end tanks with 3″ inlets; fortunately for James it came with brackets already built for the Evo front end…

When James purchased the car from the previous owner, he was given an option to have an upgraded turbo kit included as a packaged deal. After doing the necessary research James jumped on the opportunity…

IMG_20200216_143017

One of the more exciting things about owning a turbocharged vehicle for James is being able to have an external wastegate…

IMG_20200216_143011

IMG_20200216_143004

With the build moving forward, James knew he would need a larger wastegate to accommodate for his goals. In came a used Tial 44mm that would be adequate in handling the boost pressures…

IMG_20200216_143430

IMG_20200216_143438

As for the main piece selected to power the build, a used GT3076 gen 1 Garrett turbo with a modified core is what James will be using…

IMG_20190921_103302

In the past James had some unfortunate luck where motors stood; wanting to add some more reliability to the car James decided to swap the Manley H beam rods for a set of their lightweight I beams rods…

IMG_20200216_145156

A catch can was advisable not only for the track duty but also for the power range in which James was aiming…

IMG_20200216_144934

Wanting to use technology to his advantage, James sought out an Evo X gas pedal and throttle body to incorporate the use of the drive by wire system…

IMG_20200216_151021

A 4 port mac valve was also included in the mix of things to aid with the regulation of boost…

 

Another major aspect of the build that required some serious attention was the fuel system…

IMG_20200216_150008

This is an area that James made sure was more than adequate to support his future plans. He went with a Magnus billet fuel rail with plans on changing the lines throughout the entire system to AN. The car currently sat with a Walbro 255 pump but an upgrade to their 440 unit was the plan ahead along with increasing the feed line to a -10 and the return line to -6. This was all in preparation for the car to run on Ethanol fuel…

A few shots of the AN hose ends in an assortment of bends that will be used in this process…

IMG_20200216_145511

As for the fuel filter, James went to S.D.R.R and picked up one of their Racing Lines 10 micron inline units…

IMG_20200216_145949

IMG_20200216_145918

While he was in the fuel department he made sure to get a Fuelab regulator in black to go with the theme…

IMG_20200216_145602

To fully execute the AN conversion, James modified the fuel pump hanger to accommodate for the fittings…

 

Apart from his previous builds, James wanted to be more hands on with this build especially where it related to tuning. Even though James wasn’t physically involved in the scene with a project car, he still played a major role. James spent a substantial amount of time around the drag racing scene working with the timing equipment at B.A.D.D for both official race days along with practice sessions. Being so heavily connected to the scene sparked his interest in getting involved with tuning on this current build…

With the idea present, and a car to build in his possession James went about looking for an ECU of his liking. The EMU Black caught James’s attention after hearing some great reviews on the software and the ease of use. As a beginner, James figured this would be ideal for him and went ahead…

 

We’re going to close out today’s post with a shot of the additional components that came with the ECU…
