cp-e™ MZRevolved™ Mazda Mazdaspeed Short Block Stage I

Description

Mazdaspeed Short Block Stage I

Custom Performance Engineering developed the Stage I MZR 2.3L Short block as the affordable solution for higher boost applications. This is a perfect setup for anyone wanting to run a more aggressive setup without a heavy investment. Whether you are looking for a quicker street car or more competitive yet lower budget weekend track racer – this is the solution for power, reliability and a peace of mind.

All cp-e™ MZR blocks are precision machined to our spec and hand assembled with utmost care and attention. Each block is carefully blueprinted, balanced and assigned a unique serial number. All specs are carefully tracked and verified throughout the build. Stage I blocks feature factory size bores with precision honed factory sleeves. The short block features our Manley H-Beam pistons and Stage 1 Pistons. We use performance main bearings. Our Tri-Metal rod bearings are specially coated with a Teflon based coating offering reduced friction and wear.

Each motor comes with full documentation and a spec sheet. A full engine gasket set and ARP head studs are available as well.

We recommend changing your oil every 3,000-5,000 miles, regardless of oil type chosen. High quality engines deserve high quality parts. We recommend using a proven turbocharger system, including a high performance exhaust manifold. We suggest at least a refreshed stock cylinder head for this motor. We do not cover any failures or damage to the block as a result of cylinder head failure.

Perfect choice for a street driven car. Mild to moderate big turbo build. Highly capable with necessary accompanying upgrades. We do not guarantee any specific horsepower number.

Refundable Crate Core Charge- $350

If you want the least expensive option and don’t care about a long turnaround time, the crate charge is the way to go. With this option, we build YOUR motor. We must receive a block that is in rebuildable condition with this option. Any modifications that you select will be done to your personal motor, so lead times will be MUCH longer. To ensure secure and safe transport we provide a plastic crate and block mounting hardware specifically for the MZR short block with packing instructions. Return shipping label is included. Lead times are longer with this option, we will process the block upon receipt and ship it back out once build is complete. Full Crate Core Charge refunded upon return of your crate.

Please review our Engine Core Requirements page to determine if your core will be eligible for return.
