Axis Power Stage 5 Motor 2.5L Subaru description
A new offering, the Axis Power Racing Stage 5 Motor. Same components essentially as the Stage 4.5 Motor but this uses an STi case and retains the 2.5 Liter displacement.
This is the race engine you are looking for. It will handle 30+ PSI of boost and large amounts of nitrous. The thick Darton Sleeves we press in help this block to take those boost pressures or nitrous use with ease. It is a proven winner with the combined parts that make up this monster.
We had our friends at CP make us some custom pistons that will stand up to the abuse you may put this engine through. Pauter Machine is the choice for forged connecting rods, they are tested to withstand almost anything. We use a forged crank and modify it for better oiling and finish with balancing & polishing it to within .25 grams at 10,000 RPMS.
