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.

IMG_4987   Now that most of the mock up was complete, we disassembled the car and gave Jesse a slew of parts for him to work his magic on. The quality blew us away when he brought them back after powder coating. We knew this would be the head turner we envisioned from the beginning now.

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.

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 waste gate on the intercooler piping to regulate boost pressure, and allow for a better torque and turning a procharger into a TORQUE MONSTER.   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 can produce about 20 psi of boost, but the wastegate will be able to regulate it. The Tial  BOV is located under the MAF on the left side of intercooler,  which Would cause distorted readings.  To solve this, we relocated the MAF to the cold-side intercooler pipe. we also added a PMAS Hpx  Frequency Maf to allow the proper scaling for this setup  This smoothed out readings and allowed us to get accurate data while tuning.

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. Once all of the fabrication was done, it was pulled onto our Dynojet for some tuning.

dsc_0637editdsc_0679editAfter some work on the Dyno this thing laid down an Impressive 702whp and 575wtq at 13 pounds of boost. The tune was Done through Hp Tuners.  The blue lines are from the previous tune with the procharger before the smaller pulley and other modifications we did this time around. It’s definitely a substantial increase in power

TUNED: Camaro SS

The shop was rumbling thunder yesterday with this rowdy Camaro SS on our Dynojet. It arrived with an aftermarket intake and exhaust installed and we unlocked the true power potential hidden under the hood.  As you can see, a good tune goes a long way in maximizing the effectiveness of your modifications! Bring your car to PSI and let us unleash your cars final form!

Baseline: 320WHP / 318 ft-lbs
End result: 360WHP / 344 ft-lbs

TUNED: Sweet Lou’s S13

Lou brought his S13 by for some love to get it on the track this weekend for a drift event.  Before getting down to tuning, we did a  proper break-in session on his freshly built SR20.  Several miles going through varying load patterns on our Dynojet allows for the ideal conditions to ensure a new motor’s longevity.

We set his power at a safe level given that the fuel system was running out of headroom and he will return after the event for more mods and even MORE POWER! The end result will be an easily obtainable and track reliable 350WHP.

TUNED: Brian’s Focus ST

Brian brought his Focus ST to us for one step colder plugs, a few small tweaks, and a retune. We wrapped the inlet pipe with high quality Mishimoto gold reflective tape to reduce inlet temperatures. For the money you can’t beat the performance of this ST!

-Mod highlights: Cobb intercooler, intake, charge pipes, turboback, and Accessport

End result: 274WHP / 360 ft-lbs

200WHP N/A LS/VTEC Integra tune

This Integra came in a while ago with the LS/VTEC conversion already completed. It had a few issues and dynoed in the 150-160WHP range. The owner then picked up a new exhaust, installed Acura RDX injectors, a Walbro 255 fuel pump, & brought it back in for a retune. Using Crome, we tuned it to put down 197WHP with ease. Seeing no reason to push every last ounce out of it we left it at this conservative level in anticipation of a Skunk2 throttle body, cams, and intake manifold.

This is another car that may not have put down a lot of power, but shows what the right parts and good tuning can do. The next round of mods will put this well over 200WHP which will make this already fun car a blast to drive on a daily basis. Check back for updates soon!

If you’re looking for work to be done on your car or getting a custom tune contact us at the shop! With this nice weather everyone is on a mission lately.

 

RB25 single turbo swapped S13 240sx

Here we have a S13 240sx with a legendary Skyline RB25 engine swap. Along with the swap the car is running full supporting mods & a single Garrett 55mm turbocharger. Let me just say, the looks of this car may be controversial with the bright metallic blue paint, widebody body kit, old school non “fitted” wheels, and non “stanced” suspension, but there is no denying the sound & power the RB25 engine produces when modified correctly.

The car was a pleasure to tune & listen to until some small problems arose. The car was running an “ebay” turbo kit with a legit quality Garrett turbo. The external wastegate that was installed wasn’t functioning properly causing severe boost creep the higher the RPM’s climbed. While we wished the car was equipped with higher quality parts to help produce the true potential of this setup there was nothing we could do at the time. To make the best of this situation, boost was set to 14psi and revlimit was set to around 6,500 RPM’s. With keeping max RPM’s here it kept the boost from soaring up to unsafe levels.

Once again this proves that you should use quality parts when modifying your car. Luckily we were able to reach the 340-350WHP goal the owner was looking for, even though we really wanted to make 400WHP with this setup. If your looking to have your car tuned give us a call at the shop! You won’t be disappointed, our tune results & customer satisfaction speaks for itself!

Enjoy the sound of this JDM swapped beast:

1JZ Supra swapped 350Z!!!

Where do I start on this unique…controversial heart transplanted Nissan 350Z? I guess i’ll start with the background. After running multiple VQ35 motors (n/a as well as turbo setups) the owner of this 350Z was tired of having expensive issues and wanted to try something different yet more reliable. So in went the 1JZ 2.5L turbo Toyota Supra motor which has been known to be rock solid over the years.

The car was dropped off to us with the motor in the bay, some wiring done, but overall in need of a lot of work. We built a custom intercooler setup for the car utilizing a Tial QR bov, custom intake, and a full 3″ exhaust that steps up to 4″ in the rear section giving it a unique sound to go with the unique engine swap. After finishing the wiring & other miscellaneous odds and ends we fired it up and boy did it sound wild.

For now, the owner is leaving it stock ecu until funds allow more upgrades so we decided to do some basic data logging on the dyno before it leaves the shop. So stock ecu, stock tune, stock boost with the above mentioned mods left us at 290WHP & 280wtq. We would love to get a tune as well as a few more pounds of boost in this thing, but for now its a responsive fun ride that makes more wheel horsepower then a bolt on VQ35 that originally would of came in the car.

These are just the type of projects that we enjoy here at PSI PROformance, whether they are loved or hated on. We take pride in doing the work other shops can not complete & putting out quality custom fabrication work which can be seen here. Enjoy the video below and don’t hesitate to contact us to get your custom project underway!

Turbo Integra GSR DA tuned

It’s not often you see Acura Integras of the DA era around anymore. Forget seeing one in general, how about a GSR model, that’s clean, turbocharged, and makes 250whp!?!? This Integra is running the original B17 VTEC motor (134k miles on it) along with an Ebay .50trim turbo, FMIC kit , Drag exhaust manifold, and 550cc injectors. The car rips for only making 250WHPat 8psi.

Now many people may think that is “low” for a turbo Honda on a .50 trim, but lets remember this is on an original motor and get this, an original STOCK FUEL PUMP. The pump will be switched out for a Walbro 255 unit & a few other small changes will be made in the upcoming weeks. The owner will then bring it back in & were hoping to see around 300WHP depending on the conditions. The tune is safe, reliable and makes strong power under these circumstances to hold over until more mods can be completed. For now enjoy the video of it at 8psi, and don’t forget to check us out on Facebook for updates on this car and all of the other projects going on at the shop!

RX-8/MS3/MS6 etc. MazdaEdit ECU-Flash tuning!

We are proud to announce that we have been tuning newer Mazdas directly with the factory ECU for a little while now. We all have seen this in the EVO/STI world, which made things a breeze for the customer & tuner when working on the car. Also many weren’t happy with the second-hand middle man tuners that were the only way to tune the cars in the past, but that is all behind us now. If you own a newer Mazda and are looking for a tune please give us a call so we can discuss it more directly.

One of the cars we had in for a MazdaEdit tune was this RX-8 rotary with a K&N intake and stock exhaust running a test pipe. These are known be to overrated on the quoted factory horsepower numbers & this one was no different. After tuning the car it put down 155whp & 113wtq which was a 20+ whp gain from stock. A few more mods to help it breathe would definitely increase these numbers, but for basically being a stock car with a tune these are great improvements.

Again, if your looking to get your Mazda tuned give us a call. Our real dyno numbers & customer satisfaction speaks for itself!
