Both are 2017 STi’s, but the one on the right is getting the PSI built turbo kit. It’s pretty awesome when a customer brings in a practically brand new car for a cool build. The engine is being left stock… for now, but it’s getting the turbo treatment with a big ole Precision turbo.
The plan is to have all the intercooler piping powder coated wrinkle black, and the header & up-pipe ceramic coated by JT Coating. It’ll have a nice clean look, especially with the shaved and powder coated intake manifold. This setup will be pushing it for a stock motor, but I foresee this car getting a built engine in the near future. Here’s a few pics of the fabrication process.
Some mocking up happening right here
All back from coating and looking fresh! JT coating killed it on this one. Big thanks to them!
Everything is getting bolted up and it’s looking good. I’m really digging the wrinkle black powder coating on the compressor housing, intercooler pipes, and manifold. It keeps the car looking brand new and almost stock at first glance.
After getting finished up and tuned by Anthony, it made 388whp and 358wtq at 16 psi! This turbo set-up is capable of a good amount more, but we kept it safe due to the stock engine and clutch.
Here’s a dyno graph comparing the car when it was stock and after we finished up with the turbo kit and tune. You can see the massive difference in power. With our big tube UEL header, the 5858 Precision turbo hits full boost only 300 RPM past that of a stock STi. Having that much more exhaust flow played a huge role in making these kind of numbers that early in the RPM range. With a built engine and upgraded clutch, this kit will be ready to handle a bunch more power. A big thanks to Mike for bringing us this project, and we hope to see him and his STi back soon!
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.
And 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.
To 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.
Now lets get this big turbo Evo strapped down for a dyno tune! Check back for for some power figures.
Evo’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.
To 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.
The exhaust manifold is getting mocked up in our jig to make sure everything fits flawlessly. Check back for more updates on this turbo build!
James brought his GS-R by for some exhaust touch up work. Now that it’s daily driven, the straight pipe had to go. Fireballs are fun, but going deaf is not! We installed a Vibrant race metal core catalytic converter to both help turn down the angry bees as well as please the law. Added benefits over a traditional ceramic cat include better resistance to vibrations and up to 40% more flow than OEM.

Last night we had this clean Nissan 240sx in for a dyno tune and our tuner Steve worked his magic once again. As far as the car goes, it had a RB25 with a GT35R pushing about 9.5 lbs of boost. The car made 362whp on the dyno and it makes for a fun RWD car.
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!
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!
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!
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!
