Here at PSI PROformance we have done a few recent 4-500whp rotated turbo kit Subarus with great results. Some customers just want more, and we are here to make it happen.
We have modified this STi a few different stages since the owner purchased it and after talks of wanting more power he decided on a 600hp goal.
The project began with our custom-spec built/sleeved engine, and our custom rotated turbo kit. With the power goals in mind, a Precision 6262 turbo & E-85 fuel were chosen to make it all come together. With a host of supporting mods & custom built parts done in-house the car easily put down 600 WHEEL horsepower after being tuned on our Dynojet.
We have since installed a resonator to our Race-spec exhaust and the car is happily in the hands of the owner. We are looking forward to it coming back in for a re-tune on higher boost when the owner is ready. At only 29psi the setup is not even breaking a sweat.
The customer brought the car back a week later to have us add a muffler as he was getting dirty looks from annoyed neighbors.
Please check us out on facebook to see regularly updates photos from around the shop including the build of this STi. If you have any questions regarding the build, or would like to start a Subaru build of your own please don’t hesitate to contact us at the shop. Our number is: 215-361-7100
Here at PSI PROformance we had the opportunity to work on a customers ’06 Ferrari F-430. After purchasing it he decided to do a few track days and quickly realized it needed changes. First we upgraded the brakes and suspension, which in combination with the already installed HRE wheels (20×13, 345/25/20 in the rear) the owner was happy. Thoughts of twin turboing the car were tossed around but with two other high horsepower cars already in the stable the idea was dropped. The car definitely needed some more power, but most importantly it needed more sound & feel. To get a little more power out of the car while giving it the F1 car type sound everyone loves building a custom exhaust became the next step. The owner purchased a set of Fabspeed Sport headers and gave the OK to build the rest of the exhaust. We modified the headers making them v-band, which we continued using for the rest of the exhaust. This helps with ease of installation, no leaks, and gives it a cleaner overall look.
We designed and fabricated the entire exhaust including the tips in house. Using the v-band design we are able to swap out catalytic convertors or run the section with open pipe. Being this is the owners track toy, cats have not been used. Once we finished, the owner brought us Fabspeed carbon fiber Maxflo intake covers and BMC air filters to help it breathe a little better. We installed everything and did some dyno testing on our in-house dynojet.
Stock the car put down 401whp & 286wtq. With the new intake, header, and exhaust setup the car put down 422whp & 297wtq with no tuning! That is a very respectable gain with no tuning. These motors are already built & tuned so fine that its hard to really extract much power out of them. We hope to possibly tune the car soon, but that will be a post for another day.
Shortly after the car was finished up we uninstalled the exhaust and sent it out for a High Temperature heat coating. Now it looks awesome, and performs awesome with no potential cooling issues from the thin wall piping.
We are very proud of the way this turned out and even though it sounds awesome in the video there is no way of truly appreciating it without hearing and seeing it in person. We hope you enjoy the small video that was put together, and if you have any questions please shoot us a PM or call the shop.
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.
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.
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.
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!
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.
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!
