P2P 4B11 Stage 1 Short Block

Product information


Our Stage 1 motor is the most popular motor and the largest value to be had in the market. Just because this is our entry level motor, doesn’t mean we don’t spend the same amount of time perfecting the geometry and creating a truly balanced and blueprinted motor. Our engine program has been proven time and time again on and off the track. We have countless race hours on these engines as well as millions of street miles that prove you can have the best of both worlds. We balance and blueprint everything in these engines. Our goal is to provide the customer, you, with entry to a level of engine building normally found in super cars and race teams. Our goal is your success, we are not afraid of any problem, and will assist you with any questions.

Why Choose our Stage 1 Short Block Over the Competition? All machining, cleaning, and assembling are done by a degreed engineer. We provide a level of artisan craft in our engines only found in race teams and super cars. The experience we bring to our engine program is unparalleled in the industry. We blueprint the entire assembly of the motor to within .0002 of our 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.
