The whole engine upgrade package came next to build a stronger block and heads to support additional power. The engine block was sleeved with Darton MID with CP pistons and Carillo Connecting rods. All the case bolts and head studs were replaced with ARP for added strength.  The heads were equipped with Ferrea oversized valves, springs and retainers complete with custom port & polish for optimum flow on the heads. Flow testing shows a 15% flow improvement .With a fairly conservative tune on E85 fuel, the car achieved 301 whp and 219 lbs/ft on our Dynapack dyno. Tuning was performed using Ecutek which is the best tuning solution for BRZ/FRS FT86.

With meticulous tuning by Edwin Tang, we are achieving a car with great drivability and power with additional feature launch control, flat foot shifting, and auto blipping.


Tyler P. 06 EVO

Tuesday, February 3rd, 2015

Tyler dropped off his 06 EVO IX for some work to be done. When I first saw his evo it was a very well set up car from the RPF1 to the GT Style wing which gave a subtle aggressive street look. I really like what he has done.

Onto what we have done, we installed a set of Cosworth Camshafts and a larger fuel pump. The cams do add a mild lope and makes the car just sound simply beautiful. This should be a very fun street car for him to drive daily or simply a canyon cruise on the weekend.

Kenny T. 04 WRX

Tuesday, February 3rd, 2015

Kenny dropped off his 04 WRX to have a few things upgraded on his car. The best thing any owner of a WRX can do is simply upgrade the turbo. Kenny had purchased a Tomioka Racing TD05-18G turbo for his car and was anxious to get it on. Well don’t we all get anxious when we get new parts to install? Here is a list of what has been done to his WRX

Tomioka Racing TD05-18G

Larger Injectors

Larger Fuel Pump

Up-Pipe w/ EWG

Turbo XS Top Mount Intercooler

COBB adjustable internal wastegate bracket

Once we had all his new parts installed, we finally got the car on the dyno and ready for a custom tune.

With the custom tune Kenny’s car made 270WHP and 227TQ at 15PSI tapered to 10PSI on 91oct. which gave him a net gain of 48whp and 39tq from the stock set up.

2013 Subaru STi Hits 390WHP

Saturday, January 24th, 2015

We recently worked on turbo upgrade for 2013 Subaru STi who customer wished to add more power before doing engine internals upgrade.  The car arrived with Injector Dynamics 1000cc fuel injectors, AEM Cold Air intake, headers, downpipe and 3-port boost solenoid. The customer chose the latest bolt-on Tomioka Racing Hybrid ball bearing TD05-GT28 turbocharger with Billet compressor wheel for his upgraded turbo.

Tomioka Racing ball bearing turbo uses genuine Garrett Ball Bearing and complemented the CHRA with their proprietary aerodynamic turbo blade design.  The size of the hybrid turbo is similar to Garrett GT28. The turbo also came with billet 1.3 bar waste-gate actuator and 8cm turbine housing.

With a conservative tune and peak boost at 18psi, the car hit 339whp and 354 lbs/ft of torque.  Target boost was achieved at less than 4500rpm. The next addition for the customer is the front mount intercooler kit, Tial QR Blow-Off Valve and Tomioka Racing temperature controlled Oil cooler kit and VP C16 Race Gas. We’re pushing the envelope on the turbo and stock EJ25 block.

With peak boost at 23psi, the car powered to almost 390whp and 390 lbs/ft of torque. The target boost was hit slightly later at 4650rpm.   The peak boost level was held back by the 3-port boost solenoid not able to regulate past peak boost of 23 psi. Otherwise the car could easily push beyond 400whp with the current set-up.  We’ll have to see if customer is willing to switch to better 3-port boost solenoid to experience the full potential of his build in the near future.  Overall this is a very efficient ball bearing bolt-on turbo for enthusiast who likes quick response and those who aspire to go beyond 400whp.

Other modifications on this car include Tomioka Racing Air & Oil Separator, 17lbs lightweight battery and throttle controller.

2015 Subaru WRX w/ Prototype Tomioka Racing Catless Downpipe

Monday, October 27th, 2014

We installed the prototype of Tomioka Racing Catless Downpipe on the 2015 Subaru WRX. With the catless downpipe we expect to see gains in low end torque and engine response. We had previously installed the TR Engine Oil Cooler, Cobb Accessport V3, and re-flashed the ecu using the stage1 off-the shelf tune. These minor modifications showed improvements of 10whp and 25wtq from the stock 191whp and 225wtq. Also keep in mind that this was done on our DynaPack dyno which reads lower than most.

With the addition of the TR catless downpipe things got pretty interesting.  We had gained 19wtq, but had lost 7whp. Although we had lost nearly the 10whp we gained from the stage 1 re-flah, the increase in low end torque and engine responsiveness was amazing. You can also see that the power is higher at the lower RPM to about 4500 RPM. One thing to note here is that this was not a pro tune. The car is still using the stage 1 map from Cobb. I would expect to see gains in both WHP and WTQ and smoothness with a pro-tune.

As you can see, peak torque was reach much sooner, and the power was smoother up to 5000RPM where a custom tune will help.

EDO Performance & Tomioka Racing 2015 Subaru WRX: Engine Oil Cooler

Saturday, October 11th, 2014

So we have seen the 2015 Subaru WRX made 191whp and 225 ft/lbs from the factory and after re-flash using Cobb Accessport V3 the power jumped to 221 whp with 250 ft/lbs of torque on the dynapack dyno.  Next, we are installing the latest product from Tomioka Racing the temperature controlled engine oil cooler kit. The temperature- controlled oil sandwich adapter adds extra protection to the engine during cold climate with quick engine warm-up and kicks into operation when the engine oil is too warm.The Tomioka Racing cooler utilizes a SETRAB 16-row cooler core well known for its durability and performance. The Tomioka Engine oil cooler kit includes the thermostat adapters, AN8 stainless steel lines assembled with the aluminum fittings and the mounting brackets.

The compact core fits perfectly behind the front bumper beam and the limited ducting space behind the bumper beam fits perfectly for the AN8 stainless Steel lines. The cooler kit comes standard with the additional sandwich plate to accommodate the top-mount oil filter.

With the engine oil cooler installed, we test drove the car in normal street driving condition. The graph below shows the engine temperature difference before and after the installation of the oil cooler data-logged using the Cobb Accessport V3. The result is we saw a temperature drop of 14 degrees. Before the engine oil cooler installed, the engine temperature was at 210 degrees on average and after the oil cooler was installed the temperature average dropped to 196 degree.

2015 WRX

With the release of the 2015 Subaru WRX and a major shift in Subaru’s design elements; automatic transmission option, equal length headers, and a CVT transmission, Tomioka Racing took on the challenge of researching and developing performance upgrades and balancing for the 2015 Subaru WRX. One of our customers agreed to allow us use of his car for R&D purposes for the next few months.

One of the first goals here at Tomioka Racing was to get a baseline reading of the 2015 WRX. We put the car on the dyno and did a few baseline runs. The car stock, made 191WHP and 224 ft/lb of torque at an AFR of 10.88 to 1. The base run showed a quick pick up in power and torque in the low RPMs (1000-3000), with peak power at 5800 RPM and peak torque at 3400 RPM. After getting a baseline we installed a Cobb Accessport V3 and reflashed the car with a Stage 1 OTS (off the shelf) map. Again the car was put on the dyno to see the difference with the Cobb Stage 1 Reflash. With the Stage 1 map, the car made 221WHP and 250 ft/lb of torque at an AFR of 10.88 to 1. With the Stage 1 map, the car saw faster spool up power with a drastic increase between 1000-3000 RPM but a slightly slower pick up in torque, with peak power at 5100 RPM and peak torque at 3600 RPM. With the use of the Cobb Accessport and Stage 1 map, the car saw an increase of 30WHP and 26 ft/lb of torque. EDO Performance Provides reflashes and tuning for the 2015 WRX, starting at $250.

TR 2015 WRX Stock vs Cobb stage 1

Tomioka Racing plans to expand on the 2015 WRX platform, eventually producing parts and other support for this car. Check Back in the near future to see what has been done and what improvements have been made to this 2015 Subaru WRX.

’03 WRX Exceeds Expectations (Tuning)

Monday, March 31st, 2014

Before and after dyno graph of the 2003 WRX Subaru

Now who said lil ole’ early 2000 Subies aren’t able to reach this much power!? What an upgrade! After looking at the results I felt as if I just watched a 70 year old retired NBA star dunk a basketball just like the old days. He’s a bit older but hey, he still got it; just like this 03 WRX! So for those of you driving a much older vehicle, perhaps even older than this, keep in mind that with a healthy engine compression you can still achieve these kind of results after tuning your vehicle like this one with out a problem!

Call or EMAIL us if you’d like to set up an appointment for tuning or for quotes! We’re open Mon-Fri 9AM-6PM
