One of the most important factors in designing an engine is that we must emphasize power and torque within the RPM band where the engine will spend a majority of the time.
So will this engine be for a weekend warrior, drag racer, street performance racer, or basic street performance as an everyday driver? All these factors matter along with budgetary parameters as your application may be somewhat complex. Of course we'll help you make the right decisions that will fit your budget, produce power and torque, and give you the the most enjoyment with your new engine. That's what we are here for!
Rebuilding an engine can be a very rewarding experience. You can learn alot about how the inner workings of an internal combustion engine are layed out and which parts are important to replace. Remember that it's important not to "overbuild" and to save money where possible. A common fault of many other engine builders is their inability to analyze their customers needs. This produces an expensive engine with exotic parts that will never be needed for the application and in turn can disappoint the customer and create buyers remorse.
Below are the items that are included in the stage 3 short block package: Rated 1000hp
Machine Shop Services
Your used block will go through our entire machine shop process to ensure it meets the highest specifications. We start off with a hot tank cleaning service to bring it back to factory clean and then inspect it for any cracks. The block is then bored and plate honed using a torque plate. Final clearances are checked and the block goes through a final cleaning to make sure there is no debris left over from the machining process.

The Mazda MZR engine relys on 3 friction washers between the crank pulley and sprockets to help keep the motor in time. This works very well for stock power levels and even mild big turbo setups. Once you reach the 450whp mark, slipping timing can become a problem. This can lead to catestrophic engine failure amounting to thousands of dollars in repairs. We have developed a square keyway which locks the crank pulley and sprockets from slipping on the crankshaft and eliminates the need to replace the friction washers and crank bolt every time it is loosened. Please note the crank pulley and sprockets are not included and must be purchased separately.
