P2P Racing Stage 3 EJ Cylinder Heads - Dual AVCS

P2P Racing's Stage 3 head package matches GSC dual springs, larger lift/duration S2 cams, and a full port to maximize airflow without sacrificing driveability. These are the heads we run in our Time Attack Sti. We keep these heads reliable by retaining the stock valve size, as most people that use these heads, do so on the race track. +1mm valves reduce the seat thickness and can result in a crack causing catastrophic engine damage. If you would like to run to the absolute limits of these heads, please check out P2P Racing's stage 4 head builds as they incorporate a thicker/deeper aftermarket seat. These heads are far superior to stock heads and are made to last. The New OE castings are taken to our in-house machining center and the valve seats are cut with radiused multi-angle seat cuts that allow for maximum airflow, while retaining seat longevity. The porting is hand ported as this allows for the most precise flow matching capability. All castings shift slightly, and if a head is not ported by hand and tested, the results in each runner may vary if, for example, a CNC port without hand porting is done. The spring and cam combination is perfect for our stage 3 or stage 4 short blocks and their ratings.

Why Choose our Stage 3 Head Package Over the Competition? 

All machining, cleaning, and assembling are done by a degreed engineer. P2P Racing provides a level of artisan craft in P2P Racing's engines only found in race teams and super cars. The experience we bring to P2P Racing's engine program is unparalleled in the industry. P2P Racing blueprints the entire assembly of the motor to within .0002 of P2P Racing's specs. It is incredibly important to balance your motor to increase the life of your bearings. It is highly recommended to run a Fluidampr/ATI crank pulley or OEM. Do not run an aftermarket solid crank pulley. All of our inspection equipment is high quality, either from Starrett or Mitutoyo, and is sent off yearly for calibration to a qualified cal-lab.
