2016 Subaru STi – ProTune

Category : Automobile Performance

Took on this vehicle one evening as this client had bought a few performance parts from us and it was time now to have the STi calibrated.
Oh yeah the client did a phenomenal job in the install of all the items.

Mods on this vehicle were:
IAG air oil separator, Invidia up pipe, down pipe, CBE, 3port EBCS,
killer B pickup / windage tray, Perrin blow off valve, Cobb Tuning SF Intake, Grimmspeed TMIC, turbo inlet pipe and the pitch stop mount.

Have to say this was a very healthy motor and it showed as it was one of the highest EJ257 that I was have had the pleasure of calibrating with the practically stage2 mods on the vehicle.

This is a return client whom bought some nice Gram Lights wheels from us.  Well he was at it again and this time it was some preventive items that he wanted to add to the mix. After those items were installed he wanted us to do a calibration on his vehicle.
Contacted our reps and soon the IAG Performance, Cobb Tuning and Killer B Motorsports items arrived.

The IAG Air Oil Separator was not given a close up picture, but it was installed. You can see it on the left side of the top mount intercooler.


Above is the dyno jet comparison chart showing the whp vs PSI.  Next up we will be upgrading the TMIC, EBCS and regular maintenance.

2019 Subaru STi – Stage 3 install & Calibration

2019 come in to get a plethora of items installed.  This client just recently moved to the state of LA and was looking for a reputable shop to take care of his vehicle.

When the vehicle first came into the shop it was a hot summer day and we placed it on the dyno to get some baseline numbers first.

Now after the baseline was done then we proceeded to start installing the items.

In addition we recommended the client to install a  #killerboilpickup and windage tray as well as a #iagaos

2016 Subaru STi – RevWorks Short block install

Tags :

Category : Automobile Performance

A client came in one day to have his car calibrated.  As the dyno test was being done we noticed that the engine was not making the right power for the boost level that it was in.  After a compression test was made on this EJ engine, it revealed that a short block was needed.  Later it was discovered that the vehicle did not have the right calibration with the parts necessary for that level of power and psi that was being delivered to the engine.  This created a issue to the turbo and the oem turbo gave up the ghost. Along with the oem turbo getting damaged the engine lost compression in 2 cylinders.

Now that we needed a new short block in came the guys from RevWorks Inc.  Got together with Scott the president of that company and he guided me in the right direction to get this vehicle back on the road.  Took a few months to get the short block built and sent to us but it is finally in the shop and the build is coming together.  Here are the specs of the short block from RevWorks:

RW_EJ25_Stage2_ Block 100mm (RW600)

OEM STi Crank
Manley H Beam rods
ACL Race Rod Bearings
ACL Race Main bearings
Wiseco AP 100mm 9:1 Pistons
New Case Bolts (Mains)
KillerB oil pick up
ARP Headstuds / OEM full gasket kit

In a few days we will be having the new engine in the bay and ready for the break in procedure as per the RevWorks instructions.

3/12/19 – This is where we are at the moment on this build.  Hoping to get one item in to continue with putting all the parts back on the engine.

One of our good clients had a mishap on 2016 Subaru STi, yeah you all know the infamous ringland failure due to the crummy OEM oil pick up. So he did not waste time in going for something better that will give his AutoX duty vehicle the piece of mind.  In comes the short block from IAG, and a plethora of performance parts to take advantage of this wonderful robust short block.

Parts on this build include great performance names such as:

Fuel Injector Development 1300cc / Tomioka Racing GTX2971R / Radium Engineering FPR / Gates Racing belt
Mishimoto Rad. cap / KillerB Motorsports oil pick up & windage / IAG Short block, TGV Delete kit, Fuel rails & spacers / Torque Solution Fuel Line kit / Cometic Headgaskets / OEM gasket kit, oil pump & water pump / Grimmspeed TMIC coupler kit / ACT Heavy Duty Street Clutch.

I am sure I am forgetting something but nevertheless I will add it later.  So on to the pictures of the parts of this build which should keep the client busy for some time.
