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.

Factory Five 818 Car

This is a project that you don’t see every day. A customer brought us a Factory Five 818 kit car. It was running a completely stock WRX motor and 5-speed with a Megasquirt MS3Pro controlling everything.

We ended up tossing on a very lightly 2017 STi turbo and intercooler to make this thing even more fun. It currently doesn’t have its body, but it’s definitely cool to see all of the inner workings of the suspension and frame.

dsc_0847dsc_0860dsc_0851We’re going to get this over to the dyno for some tuning action. With the weight of this car just touching 2,000 pounds, I can’t imagine how much fun it’ll be to drive. I’m thinking this will end up around the 300whp mark. Possibly more since it’s now rear-wheel drive instead of all-wheel drive. Once it’s all tuned up the owner is going to put the body on it and bring it back for a custom exhaust. I can’t wait to see it once it’s all buttoned up.

RWD WRX Build – Part 3

dsc_0368This build was getting buttoned up last week. The car made its way onto the dyno, and it was LOUD. The titanium hood exit makes this thing scream. A few things still needed to be buttoned up, but everything else was ready for engine break-in and tuning.

dsc_0522edit dsc_0587editOnce tuning was done, the last few details were finished up.  The hood exit looks sweet with its burnt titanium trim on the hood. It’s definitely a cool touch. Attention to detail is a huge part of all of our builds, and it especially shows with this one.

dsc_0495editThe face of the WRX was put back on, and the car was sent on its way. That wraps up this build for now!

Here’s a few more pictures of the car during its build.

A Super WRX

Today at the shop we had this Subaru WRX on the dyno for a tune. This Subaru WRX looked stock but was far from it with all of it’s modifications.  These modifications included a Blouch 16G Turbo, 650cc Injectors, Perrin Up Pipe, Agency Power Downpipe, AEM Intake, HKS Catback Exhaust, and a Hallman Boost Controller.  With these mods the car put down 307whp and 284tq, making a fun and awesome daily to whip around town. Here are the pictures and video from the dyno session, and don’t forget get $100 off a dyno tune for the month of December, so get your car in for a tune today!

A Sleeper Subie!

Today at PSI PROformance we had this Subaru WRX STI Hatch in for a dyno tune. It appeared pretty much stock on the outside, but it had plenty of work under the hood to push some power. Some of these modifications include a FP Red turbo, Front Mount intercooler, Full Race Equal Length Manifold, and Wiseco Pistons and Eagle Rods. With these mods the car was able to make 429 whp and 400 tq on about 23 pounds of boost. Here are the photos and video from the dyno tune. Enjoy!

Zoom Zoom!

Today we had one Mazda MS3 in for a tune that lived up to Mazda’s slogan of  “Zoom Zoom”.  From the start you could tell this car meant business with its growl from Cobb bolt-ons including an intake and exhaust.  This MS3 was also sporting a front mount intercooler and a TB30r Turbo, but besides that the car was mainly stock.  Even with it’s mainly stock motor, this Mazda was able to put down 374whp and 347tq, which is quite impressive.  We look forward to even more power and updates from this car in the future.










Freedom Moves!!!!

Over this past weekend was Freedom Moves presented by Club Loose, which is an all around weekend of awesomeness.  There’s partying, drifting, and hanging out with old friends.  A couple of our customers were tearing it up, including Josh and Jim in their 240’s.  Here are some pictures of them in action at Englishtown Raceway Park.  We are looking forward to the next event, which is Finishing Moves on October 1st.
