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

Earn up to 386 BoostBucks.

With the continuously developing mazdaspeed world, we have redesigned our stage 2 motor to be a more affordable solution for those wanted to make lots of horsepower without the need for a fully sleeved block. The stock sleeves in the mazdaspeed have been proven to hold north of 600 horsepower at the wheels. The stage 2 motor is a motor designed to hold that power level and more at an affordable pricepoint, without sacrificing quality. The stage 2 motor has ARP mainstuds, stage 2 pistons, and I-beam rods, to compliment the upgraded bearings and keyed crank found in all of our MZRevolved motor line. We suggest this motor for those with running high octane fuels, a big turbo, and cylinder head upgrades.

Stage II block features a factory size bore with precision machined factory sleeves. The MZR blocks are precision bored and honed to match the stage 2 pistons, line honed for the main studs, and finished off with a precision block decking procedure to ensure a good seal between the block and cylinder head. The short block features our Manley H-Beam rods and MagnumDI Pistons. ARP main studs are included. 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.

Excellent motor for track use and abuse. Highly capable with necessary accompanying upgrades. We do not guarantee any specific horsepower number.

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 an upgraded cylinder head for this motor to match the higher compression ratio. We also suggest using e85 blended gasoline or race gas for the higher in-cylinder pressures.


“I

I Beam Rods

cp-e™ has chosen Manley as its manufacturer of choice for connecting rods.  Manley’s I-beam connecting rods are formed from billet 4340 steel.  4340 steel is a heat treatable, low alloy steel containing nickel, chromium and molybdenum. It is known for its toughness and high strength in the heat treated condition while retaining good fatigue strength.

“Stage

Stage 2 Pistons

Engineered with performance and strength in mind specifically for the Mazda MZR 2.3 DISI motor these Stage 2 pistons will hold up to almost anything. Made using a state-of-the-art forging process with extensive heat treating and special finishing, cp-e™ ensures optimum reliability which is exactly what is needed in a high performance engine.

“Keyed

Keyed Crank

In order to prevent slipping timing in high horsepower builds, all of our cranks have been keyed to ensure a locked in fitment.


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.
