  • 2018 Subaru WRX

    James brought his 2018 Subaru WRX in for his next round of modifications!

    Up first in the shop, John removed the factory plastic intake manifold and replaced it with a more Subaru aesthetically appropriate wrinkle red powder-coated forward-facing BRZ intake manifold, beautifully packaged by I Build Racecars, topped off with a front-mount intercooler system from Extreme Turbo Systems featuring that unmistakable cold side titanium charge pipe, all complimenting the existing modifications perfectly, including a down-pipe and SF air-intake system from COBB Tuning, a Street Series air/oil separator from IAG Performance, and a 3-port electronic boost control solenoid kit from GrimmSpeed.

    With the mechanical work wrapped in the shop, Matt strapped her down to the rollers for Vlad to perform a custom Pro Tune via COBB Tuning‘s Accessport. With 93 octane in the tank, and the factory turbocharger delivering 21psi, Vlad increased the FA20DIT’s output to a solid 338.93awhp & 342.05lbft! Great improvements both in terms of performance and under-hood aesthetics as well!

  • 2018 Subaru WRX STI Type RA

    2018 Subaru WRX STI Type RA

    Casey brought us his 2018 Subaru WRX STI Type RA, 1 of only 500 produced, for the first round of modifications! Up first, Matt performed some baseline dyno pulls to establish a starting point, coming in at a healthy 287.09awhp & 293.31lbft. Up next, Alex installed an SF intake system from COBB Tuning, a Street Series air-oil separator from IAG Performance, all topped off with a turbocharger-back exhaust system from COBB Tuning.

    With the mechanical work wrapped in the shop, Matt strapped her back down to the rollers for Vlad to perform a custom Pro Tune via COBB Tuning’s Accessport. With 93 octane in the tank, Vlad increased the EJ257’s output to 323.76awhp & 360.62lbft, picking up 36.67awhp & 67.31lbft at peak, and 60.03awhp & 81.82lbft in the mid-range! That’s definitely a difference Casey will notice, and should keep him entertained (for a while). It’s great to see a Type RA being thoroughly enjoyed as a modified daily driver.

  • 2015 Subaru WRX STI – IAG Shortblock

    2015 Subaru WRX STI – IAG Shortblock

    Steve brought his 2015 Subaru WRX STI back in for the next round of work! First round, Steve came in with a goal of a super-responsive 400awhp & 400lbft on pump gas, while also laying the groundwork for more power down the line if (when) he wanted.

    With his end goal of 500awhp+ in mind, Steve jumped straight to an IAG Performance Stage 2.5 Closed Deck short block, along with all the necessary supporting modifications for the immediate and future goals, including Garrett – Advancing Motion GTX2867R Gen-II turbocharger packaged for stock-placement by ATP Turbo, TiAL Sport MV-R wastegate, IAG Performance Street Series air/oil separator, PERRIN Performance turbocharger inlet tube, COBB Tuning SF intake system, Process West top-mount intercooler, COBB Tuning down-pipe, ARP cylinder head studs, JE Pistons Pro Seal cylinder head gaskets, AEM Performance Electronics 320lph in-tank fuel pump, Injector Dynamics ID1050X fuel injectors, all transmitting through an Advanced Clutch Technology HDSS clutch kit & Streetlite flywheel, with all the miscellaneous OEM and aftermarket gaskets, seals, and fluids needed to bring it together, all dialed in with a custom dyno calibration by Vlad via COBB Tuning’s Accessport, resulting in 400.96awhp & 412.29lbft!

    After a few months ripping around at 400awhp/400lbft, Steve started getting the itch for more power. Willing to make some sacrifice on response for more top-end performance, he opted to upgrade to an ATP Turbo packaged stock-placement Garrett GTX3076R Gen-II turbocharger, along with a Killer B Motorsport equal-length header and up-pipe. Once Alex wrapped the mechanical work in the shop, Matt strapped her down to the rollers for Vlad to perform a recalibration via COBB Tuning’s Accessport. The result? 456.91awhp & 443.19lbft on 93 octane, picking up 55.95awhp & 30.90lbft at peak, and ~100awhp & 75lbft in the top-end! While low-end and responsiveness did take a hit as expected, Steve reported that the increase in top-end performance was well worth the sacrifice!

    Up next, Steve will be making the switch to Flex Fuel, and gunning for his end goal of 500awhp+! Stay tuned for more to come from this STI.

  • 2004 Subaru WRX – EJ207 Swap

    2004 Subaru WRX – EJ207 Swap

    After several years of solid service, the original EJ205 engine in Johnathan’s 2004 Subaru WRX suffered bearing failure. But rather than restarting with an EJ205-based build, Johnathan decided to take a different route: EJ207 engine swap from the JDM Version 7 Subaru WRX STi! What’s so great about that engine? Out-of-the-box 8,000RPM+ redline, semi-closed deck block, AVCS intake camshafts, IHI VF30 turbocharger good for 300awhp+, and proven resilience to over 500awhp on stock internals — one seriously fun package!

    Once we had the imported engine in-shop from J-Spec Auto Sports Inc., John removed the damaged EJ205 engine and transferred the reusable performance parts to the EJ207 engine, along with a new EXEDY USAclutch & Fidanza Performance 9.5lb aluminum flywheel. and performed the necessary wiring modifications to enable AVCS. Next, it’s time for the final installation, first startup, and then she’s hitting the rollers to get dialed in by Vlad via EcuFlash. Stay tuned for results!

  • 2013 Subaru BRZ – Stage III Short Block

    2013 Subaru BRZ – Stage III Short Block

    Seth’s turbocharged 2013 Subaru BRZ is in the shop, and under the knife! This round, we’re setting this 86 up with an IAG Performance Stage-III Extreme Closed Deck short block, HKS camshafts (IN: 266°/11.70mm – EX: 260°/11.70mm), IAG .500″ cylinder head studs, Full Blown Motorsports cylinder head gaskets, REIMAX billet oil pump gears, Full Blown Motorsports larger capacity aluminum oil pan, new Garrett GTX3071R CHRA, and all the OEM Toyota/Subaru gaskets, seals, timing components, and miscellaneous odds-and-ends needed to bring this FA20 to life.

    Once Louis wraps the mechanical work in the shop, then Charlie is strapping her down to the rollers so that Vlad can dial the setup in via EcuTek Technologies Ltd! With the existing turbocharger system, port-injection system, tons of other supporting modifications, and a solid engine in place, this setup is definitely going to perform! Stay tuned for results!

  • 2008 Subaru WRX STI

    2008 Subaru WRX STI

    After experiencing bearing failure, Jason brought his 2008 Subaru WRX STI in to not only get the EJ257 rumbling again, but to also lay the foundation for future modifications! After disassembling the engine to determine the full extent of damage, we discovered that Jason’s quick response to the early signs of bearing failure paid off — the VF48 turbocharger, camshafts, cylinder heads, and AVCS components were all in perfect, reusable shape (not always the case after a bearing failure).

    From there, Jared got to reassembling the engine around an IAG Performance Stage-1 short block, including Killer B Motorsport Ultimate oil pickup tube, ARP 2000-series cylinder head studs, IAG Street Series air-oil separator, GDT cylinder No. 4 cooling modification, COBB Tuning turbocharger inlet mated to the existing SF intake system, GrimmSpeed 3-port electronic boost control solenoid, with all the OEM Subaru pumps, gaskets, seals, and miscellaneous components to bring it all together, with an Advanced Clutch Technology Streetlite flywheel & HDSS clutch kit transmitting the power.

    With the mechanical work wrapped in the shop, Matt strapped her down to the rollers for Vlad to perform a custom calibration via COBB Tuning’s Accessport. Even with 99° ambient air temperature, and a tapped-out stock STI intercooler, Vlad was able to increase output to 309.54whp & 352.06lbft on 93 octane!

    With the foundational work out of the way, Jason’s in great shape for turbocharger, intercooler, and exhaust upgrades down the line to get up to that 400awhp power range.

  • 2019 Subaru WRX STI

    2019 Subaru WRX STI

    Before the first oil change was even due, Justin brought his 2019 Subaru WRX STI in for the first round of work! Starting out in the shop, Louis set the EJ257 up with a COBB Tuning SF intake system, turbocharger inlet tube, down-pipe, 3-port electronic boost control solenoid, complete Flex Fuel conversion kit with pressure sensor, Injector Dynamics ID1050X fuel injectors, GrimmSpeed up-pipe, and a PERRIN Performance recirculating blow-off valve.

    Up next, she hit the rollers for a Flex Fuel calibration by Vlad via COBB Tuning‘s Accessport! With the stock short block still in place, Vlad proceeded cautiously on both 93 & E85 calibrations to keep the torque in check — resulting in 93 octane output of 312.12awhp & 329.77lbft, and E85 output of 325.70awhp & 360.89lbft! Solid results for the first round of work!
