Here at Mazworx, we can prep your block to your specifications. Utilizing our CNC capabilities and state-of-the-art equipment, you can ensure that the machining process is done properly. For more understanding of our process, see the additional information section.The Stage 3 package is designed for DIY engine builders that want a high performance street/strip upgrade. This will be good for and engine making up to 1000hp.
Hot Tank Cleaning:Wash your block to get oil and grim off.Sand Blast Block:Since these blocks can be over 20 years old, they may start corroding. Sand blasting the block will get the corrosion/debris off, bring a uniform satin aluminum color to the block and give it an overall better look.Sleeves:When planning on making 400hp, putting sleeves in is a must. Darton Dry Sleeves are made of ductile iron and are able to hold over 1000hp. This process includes the removal of the old sleeves, machining the block for the new sleeves, installation, and step decking.
Bore:Our boring process is done on a 3-axis CNC machine ensuring bores are on center. From there it goes to the honing machine. We have the latest Sunnen SV-10 cylinder hone with diamond tooling. This is for the ultimate in cylinder finishing. We can bore this block from 86mm to 90mm.Surfacing:The surface of the block will be step decked. This is done in our 3-axis CNC machine. We machine the surface so that the sleeve is taller than the deck of the block (also known as a step deck). This concentrates the clamping force around the sleeve to help the head gasket seal under high boost.
R/R Oil Port Plugs:This process includes removing all the oil port plugs. By taking out the oil port plugs, we are better able to clean all the oil galleys. Then we will retap the threads to accept NPT plugs. The main oil galley hole will be CNC machined to accept our o-ring threaded plugs. These have an o-ring to ensure proper seal and are straight threaded for ease of remove in the future.Freeze Plugs:This upgrade is part of this package. Freeze plugs are replaced with Nissan OEM freeze plugs.
Hone with Torque Plate:We make all of our torque plates for just about every block we work on. Using a torque plate simulates a cylinder head being bolted on during the honing process. When the motor is actually put back together, the cylinder is as true as it was while in the honing machine. Using the torque plate is a must with sleeves install.
Main Studs/Caps and Line Bore:All our sleeved blocks are line bored. Our line boring starts with a simple cap grinding. From there it goes into our line boring machine. With our custom tooling, we can bore the main journals within the factory specifications with ease. Then it makes it over to the line hone where it's sized to specifications.
Oil Groove Machining:The GTi-R and VE blocks come with a groove cut into the upper part of the main journals. This allows you to use a 5-hole main bearing to supply more oil to the mains and ultimately to the rods. We can do this addition to all other block in our 3-axis CNC machine.
Front Main Oil Squirter;The OEM front main oil squirter applies oil to the timing chain. These are known for popping out. We upgrade this with our own one that threads in.
Plug RWD Oil Drain Hole:If you are putting a VE (FWD) head on a RWD block, you will need this hole plugged. The RWD blocks have an extra oil drain hole that the FWD heads don't have. This is done when you select a VE Oil Pump.
Core:We will need you to send in your core block.Parts Included:Mazworx/ARP Main StudsMazworx Billet Main CapsMazworx Billet Main Girdle (optional)Mazworx Front Oil SquirterMazworx Threaded O-ring PlugsMazworx Threaded O-ring Freeze PlugsNPT PlugsNew Oil PumpOEM Nissan Blow-By Pipe
