2017 Subaru STi – RevWorks

2017 Subaru STi – RevWorks

Got a client that needed some help on this locked motor.
In came RevWorks Inc. short block

Arrival day.
After we finally received the RevWorks RW750 for this build we proceeded to tearing
the motor out of the vehicle and cracking it open to see the carnage.
The exhaust side on the driver’s side head was the leading culprit here.
Valves bent as well.
Exhaust camshafts not looking to well either.
OEM and aftermarket items needed for the build started arriving.
Assembling begins with the passenger side head as the other head will need to be worked on since new parts were order from Subaru to replace the damaged head.
New driver side head being assembled with new valves and buckets.
Old on the left , new one is on the right side.
Killer B oil pick and windage tray were installed and oil pan back in its spot.
Amsoil oil filter ready for the break in procedure.
Amsoil front and center on this build.
Outfront Motorsports were involved in helping rebuild the AVCS for this and all the EJ builds we do at the shop.
Amsoil Break-In oil is now in the engine and car has been delivered to the client.
500 miles and we will see this vehicle again to place the Amsoil Signature series oil
and proceed with obtaining the power out of this engine. Stay Tuned!

2016 Subaru STi – RevWorks Short block install

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.



Slight Port matching and polish done in house for these TGVs.
