A Stage 1 engine package will be perfect for those who are looking for a high performance daily-driven street car. Stage 1 engine build contain Mahle 4032 pistons which have a 1.2mm Nitrided top piston ring to handle high heat and extremely high cylinder pressure commonly seen in Direct Injection engines. The patented HV385 supersonic thermal spray process is applied to the top ring for superior bonding, increased durability and increased scuff resistance.In addition, the second ring is also 1.2mm but reversed twist taper faced made of cast iron. The third ring is a standard tension oil control ring. The piston’s wrist pin is an H13 Tool Steel material, which is not your standard Premium Chrome Moly nor your 9310 material. These pistons from Mahle have hard anodized ring lands to prevent galling and microwelding. The GRAFAL skirt coating itself helps reduce drag, scuffing, friction and cylinder bore wear which is something you cannot find on any other manufacturer’s pistons. The phosphate coating that gives off the grey appearance to the pistons provides a lubricant film in the pin bores and ring grooves. This will benefit you when there is a lack of lubrication such as on cold starts.
The 4032 pistons mated with Manley H Beam rods make the perfect “M&M” combination. These Connecting Rods are manufactured from 4340 forgings. They are also Heat treated, stress relieved, shot peened and 100% individually magnafluxed. The “M&M” combination has been our proven combo to hold great power reliably for over a decade. ACL Tri-Metal Rod bearings are then paired with the H Beam connecting rods which can endure high loads and high revs. Kings Tri-metal Main bearings are also used in the Stage 1 package, which also are capable of withstanding very high loads for extended periods of time. Their load rating is more than 2000 psi higher than the Bi-Metal bearings and are compatible with all types of steel crankshafts.
Another great service that we offer is the teardrop-shaped cavity machined into the Crankshaft assembly itself to improve bearing lubrication. In order to get extra oil to the rod bearings, we create a teardrop shaped cavity to the crankshaft’s main oiling holes. We then delete the Balance shaft with our BSD kit. This reduces parasitic drag to the crankshaft freeing up horsepower and also allows your engine to rev more freely. The only side effect to this is slight increase in engine vibration transferred through the chassis. The OEM Main bolts, which are perfectly capable of handling 500whp, are replaced with brand new ones.

Your used engine will go through the entire machine shop process to ensure it meets the highest specifications and tolerances. We first put the engine through our teardown process to properly inspect and clean all engine parts in our hot tank. Then the engine is inspected using a magnaflux system in-house. If any failure is to be found, you will be contacted. 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 are no debris left over from the machining process.
The cylinder head is then fully inspected separately by pressure testing and magnafluxing to ensure there are no cracks. Valves, Valve Guides and Valve Seats are also examined for excessive wear. In addition, the Cylinder head is carefully checked for warpage. This includes the block deck, intake deck & exhaust deck. After passing the examination process, the Cylinder head is milled and then reassembled while lapping the Intake & Exhaust valves for proper seating. We install Viton Valve Seals for maximum oil control and seal durability throughout the entire rpm range.
After the head is fully assembled, we then proceed with setting the Lash for the Valves. This is a crucial element in the process as it's what ensures that the valves in the head open and close accordingly with the correct clearance.
Piston to wall clearances are re-checked to reduce the amount of contact area against the cylinder wall when the piston "rocks over" during the transition from T.D.C (Top Dead Center). The Long Block is reassembled then it goes through our heat-cycling process. This will bring the engine itself up to Operating Temps (200*F) to re-torque the cylinder head studs once they endure a heat cycle.
All long blocks have a fixed shipping price of $550, short blocks is $450. Price is to the contiguous USA only.
