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.

New Turbos are Fun!

Here at PSI PROformance, we offer a variety of services including replacing blown turbos.  When Chris’s Civic Si came in the shop, he wanted a smaller turbo so he could get a better powerband through the RPMs.  We replaced his blown turbo with a smaller Precision SC5252E, and gave him a quality tune from Steve.  After tuning, Chris was able to make more power than before with this smaller turbo and less boost, which is quite impressive.  His Civic Si made 301whp and 250tq on 9.5 lbs of boost.

Our Favorite Legacy GT

The Other Day we had Kevin and his Legacy GT in for a retune after he performed some recent modifications. Some of these changes included a turbo upgrade, which was an AMR 500 Turbo. Along with a turbo, this Legacy Gt is supporting a grocery list of mods including a WBR FMIC, 740cc Jecs Injectors, Walbro 255 fuel pump, JNZ cold air intake, Borla Headers, Grimmspeed uppipe, Tial Mvs Wastegate, Grimmspeed EBCS, Invidia Catless Downpipe, and a Megan OE-RS Exhaust. With our tuner Steve working his magic, this Legacy GT was able to make 373whp and 398tq.



Also, if you are in need of car insurance then we at PSI PROformance recommend that you check out Brandon Insurance Group. All of the employee’s at the shop have their personal and project cars insured through Kevin and Brandon Insurance Group, so make sure you check them out.

Just one awesome 240sx!!!!!!!!!

The other day we had Evan’s Nissan 240sx in for a dyno tune. This Nissan 240sx was rocking a stock S15 SR20DET engine with some bolt-ons. Those bolt-ons included a front mount intercooler, 3″ Exhaust, 740cc Injectors, Walbro Fuel Pump, and an Apexi Power FC. The engine had stock cams and a stock turbo but was still able to make 310whp and 348tq, which is pretty impressive. Evan’s car is one of the nicest 240sx’s we’ve seen and now it makes a good amount of power with our tune. Here are the pictures from the dyno day, enjoy!









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!

One Beautiful 600whp Porsche

Last night at PSI PROformance we had this bright yellow twin turbo Porsche in for some dyno pulls. Being one of my dream cars, this was an awesome sight for me and everybody in the shop. This Porsche was a beauty to behold with it’s fully polished CCW wheels, and beautiful yellow paint. To go along with the looks of the car, this Porsche was sporting twin GT30R turbos pushing about 22-23 pounds of boost. After a couple of dyno pulls the car put down 641whp and 611tq, making it a serious car. I can’t wait to see what this Porsche has in store for it next.

A Not So Stock Scion

Yesterday at the shop we had this stock looking Scion TC roll onto the dyno rollers, but it was far from stock.  The moment you popped the hood, there was a nice Turbonetics Turbo Kit staring you in the face.  The only hint you get that this car is turboed is from the sound of the bov and silver front mount intercooler hiding behind the front bumper grill.  With only 7 psi pushing through the turbo, it was still able to make 246 whp and 218 tq.  Some more boost and this car would easily make over 300whp, making it a fun daily driver to whip around town!

Another 400whp Eclipse!!!!

Yesterday at the shop we had this Mitsubishi Eclipse come into the shop for a dyno tune. The car was looking really clean with it’s sparkling green paint and fresh wheels. After a few pulls on the dyno, we all knew this car had the potential to make some good power. With some simple mods such as a bolt-on 50 trim turbo, and Magnus Manifold it was able to make 409whp and 390tq on 24-25 pounds of boost. With some cams this car could easily make 450-500 horsepower.
