LS2 SUBARU

LS2 Turbo Swapped Subaru STi Build

Jesse from JT Coating had us do a big turbo build on his Subaru STi in the past and it made just over 600whp on E-85. It looked great at the shows, and performed well on the street, but Jesse wanted to build something different for next seasons events. Screen Shot 2017-10-05 at 2.08.07 PMScreen Shot 2017-10-05 at 2.08.22 PM

After discussing some options, some type of Chevy LS build was chosen based on cost, performance and overall uniqueness. We began hunting for parts, while Jesse sold off the Subaru parts we would no longer be using.

An LS2 6.0L engine and transmission was sourced and the project began. Our head fabricator Don took charge on the build and started banging out the mock up phase pretty quickly. Everything went together fairly easy, it was like the V8 was meant for the car minus a few small changes. While the engine was out a BTR cam package was installed with a few other supporting mods. As many of you know the supporting mods can be the most important parts of a project.

Once we had the general setup of the engine and headers laid out, the turbo kit began being fabricated. A cast wheel Borg Warner S475 was the turbo of choice, with complimentary Turbosmart & Vibrant pieces to bring it all together.

 

 

 

 

The excitement of seeing the turbo kit and big front mount intercooler mocked up really had us motivated to get this one running. To make all of this work, the cooling system was custom mounted in the trunk with some Radium Engineering bits and good old fashioned ingenuity.

To go along with the AEM Infinity ECU, the new CD-7 display was custom mounted in the dash to give a clean factory appearance. This makes visibility of all engine parameters easy to monitor while driving around. Plus digital displays just look cool on any race inspired project.

With final assembly under way, we gave Karl from K.P. Tuning a call to sprinkle his LS magic on the build. He came by and went over the build to finalize a few loose ends and get the car started up. It fired up without a hitch and actually sounded pretty tame still using the aftermarket Subaru cat-back exhaust. There wasn’t a person in the shop that didn’t have a big smile on their face hearing the car running for the first time. Screen Shot 2017-10-05 at 2.14.04 PM

Now it came down to strapping it on our in house DynoJet, and backing up all the long hours of work. This car runs on regular old 93 octane pump gas, so we filled up and had K.P. get to work. On only the second pull at single digit boost levels it laid down 599whp. Without even blinking an eye it was about to eclipse what the fully built e-85 Subaru setup did.  By the end of the tuning session the final horsepower number read 794whp at only 12psi! K.P. suggested upgrading the fuel system if we wanted more power, being as it is on stock Subaru lines, in tank fuel pump, and only 1000cc injectors.

Check out the dyno video below, and contact us if you have any questions about starting your own custom build. We will be starting on a second LS swapped Subaru soon with its own unique twist, and we already have a 2JZ Subaru build underway that we can not wait to share with the world.

Procharged Coyote Build

We’ve done Mustangs with Prochargers before, but this one is a little different. The owner brought us the car with the Procharger already installed and wanted to do a little twist on it. He wanted an smaller diameter pulley for more boost, but a wastegate on the intercooler piping to regulate boost pressure. With this kind of setup he will be able to run different amounts of boost up to the max psi that the pulley produces.

dsc_0233dsc_0239dsc_0228Placement of the red Tial blow off valve and wastegate was definitely important. From the outside others had to know that this Mustang was something special. We decided to mount them on each side of the intercooler so that they’d show in the lower part of the front bumper. Their red color definitely makes their presence known.

dsc_0555The small diameter pulley will be producing around 20 lbs of boost, but the wastegate will be able to regulate it.

dsc_0576While we were under the hood, we upgraded the crank sprocket and oil pump gear as preventative maintenance, since they are known to fail.

Stay tuned for more updates!

Evo X Big Turbo Kit – Part 2

 

DSC_0016 Watching a turbo kit come together is always exciting to see, no matter what car it’s on. The intense detail that goes into every piece makes it not only a car part, but a work of art as well.

DSC_0173 DSC_0188And it just looks badass once everything is bolted up, and that big turbo stairs you in the eye. This Evo is craving its appointment with the dyno. Here’s a bunch of extra photos of the turbo kit for your viewing pleasure.

DSC_0287DSC_0343DSC_0559To top everything off we bolted a massive APR Performance carbon fiber wing to the trunk.  Big wings don’t work every time, but it definitely worked this time.

Evo X Big Turbo Kit – Part 1

DSC_0876Evo’s are one of our specialties, and when it comes to custom turbo kits, we’re the best in the business. This Evo X is going to get a PSI Proformance custom turbo kit, minus the intercooler which was supplied by the owner. That means exhaust manifold, intercooler piping, downpipe, etc is all going to be custom fabricated by us.

DSC_0580DSC_0891To help with power even more, we cracked open the head for some upgrades. It was treated to upgraded cams with valve springs and retainers to go along with them.

DSC_0989The exhaust manifold is getting mocked up in our jig to make sure everything fits flawlessly. Check back for more updates on this turbo build!
