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.

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.

dsc_0930editdsc_0929editdsc_0045

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.

2017 STi Turbo Kit

dsc_0424editBoth 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.

dsc_0635The 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.

dsc_0042 dsc_0043 dsc_0202 dsc_0209dsc_0050 dsc_0389editSome mocking up happening right here

dsc_0626edit dsc_0611editAll back from coating and looking fresh! JT coating killed it on this one. Big thanks to them!

dsc_0662edit1008161623b1Everything 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.

2017-comparisonHere’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!

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.

RWD WRX Build – Part 2

DSC_0693After getting all the nice powdercoated parts bolted up, the engine was bolted back up in the engine bay. The polished Cosworth intake manifold really tops off the look of everything.

DSC_0599

Before the engine and trans were mated back together, we opened up the 5-speed for some modifications. It really is crazy how everything works inside a gearbox. So many tight tolerances and moving parts working in harmony.

DSC_0597

This shaft on the tail of the gearbox is a spool that locks the center differential, enabling it to work as a RWD transmission. The front axles will be cut off at the hubs to inhibit the front wheels from turning. The hubs will be left in place so that everything stays securely bolted together. This car is riddled with WRX performance parts. Check out our parts web store for whatever you need. Up next is going to be a titanium hood exit exhaust!

RWD WRX Build – Part 1

DSC_0966This WRX hatch was awaiting the return of its EJ255. We went through everything on this engine: pistons, rods, cams, the works. Once it’s all buttoned up, it’ll hop over to our dyno for a tune. If you want the parts going into this EJ, give us a call or visit our Parts Web Store.

A fully built engine isn’t the only thing we’re working on. There’s a unique spin on this build, or lack there of. This Subaru is no longer going to spin the front wheels when we’re done with it. That’s right, a rear wheel drive conversion is in the works. The plan is to lay down somewhere in the ballpark of 400 rwhp on our dyno when all said and done. Check back for more updates!

AROUND THE SHOP: 1

A Mazdaspeed Protege received a trio of gauges, of particular importance an AEM UEGO wideband gauge (including O2 sensor install on downpipe).

Does your Subaru Impreza sound like bees? We turned down the rasp with a Vibrant Ultra Quiet resonator installation on the customers catback. Loudness retained, buzz banished.

We also had a Nissan S14 come in for a wastegate, custom made dump tube, and oil pan gasket replacement.

Rotated 18g WRX tuned

Last week we had another Subaru in for a custom ECUflash tune. This time it was a ’02 WRX with a custom rotated turbo kit using a GReddy 18G turbocharger. With a unknown history 60k mile motor, and a host of other typical Subaru upgrades this is a classic do it yourself modified WRX. It’s a great feeling when you can help an owner finish his project by putting a solid tune on the car.

After fighting a few boost leak issues early on we were able to get back to tuning. Slowly turning up the boost the car was picking up power every pull. By 20psi it laid down 309whp on our Dynojet. The owner was extremely happy with it cracking the 300whp barrier & told us this car will have the most horsepower he’s ever driven or rode in. We felt 300whp was a good place to leave the car at for the owner to enjoy while working out a few other things on the setup.

Tons of big horsepower cars come in and out of the shop on a daily basis which can lead to expectations held high on every project/tune. This home built project making 300whp can show us all that even with “only 300whp” there is still people out there that enjoy chasing goals big and little. At the end of the day its the owner who will be driving the car day in and day out and if he’s happy nothing else matters.

Check out the video below & contact us to tune your next project!

’11 STI dyno tune

Another new model STi came in for a tune the other day, and boy are the stock tunes dangerous. We have done multiple newer body Subarus and they always seem to run very lean & make disappointing power. After making a handful of adjustments this car went from a measly 220whp to 317whp. One of the best things about the tune is that its safe. We’ve seen to many Subarus come in blown up because of “off the shelf” tunes or people beating the cars hard without a tune. It is impressive that with only 3 power mods and a tune you can pick up 100whp!

Don’t hesitate to call us today to set up your tuning appointment! Thanks for watching.

400whp 30r ’07 STi

We had a longtime customer bring this car in for a pre-purchase look over. After going over the car we found that it had low compression in one of the cylinders and was breaking up while going into boost. The customer purchased the car afterwards and brought it back in for a base tune so it could at least be driven smoothly & safely while a plan for a full build could be laid out.

Once on the dyno a small bit of tuning got the car running smooth and clean throughout the rpm range. Surprisingly even with the low compression at only 20psi it laid down just under 400whp & 380wtq! The owner was extremely happy with end result.

Knowing the engine has some issues & won’t last forever, the new owner is preparing to build it over the winter and possibly make a few changes to the turbo setup as well in hopes of bigger power. Check back in the future to see what route this car decides to take, but for now enjoy the sights and sounds of this 400whp widebody hawk-eye.
