Turbo pistons for an M50, M52, M54, S50us or S52.  Designed by Alien Engineering and manufactured by Wiseco.  This is my own proprietary piston design made with a design goal of 1300+whp.  Comes with thicker 1.5mm thick top ring to handle extreme heat and cylinder pressures and .225" wall, Trend H13 tool steel wrist pins to handle the most severe cylinder pressures.  Valve reliefs will clear 280+ degree cams with full vanos travel.  Larger valve reliefs availible on request.
 
Options for DLC coated wrist pins, lateral gas ports, ceramic coating, and skirt coating can be added to your cart from the bottom end menu.
 
Most piston options will use a groove lock spacer in the oil ring groove so the rign pack can be moved down to and leave room for the maximize ring land thickness.
 
These are also designed to sit about 1mm below the top of the block at TDC so you don't have to worry about hitting a cut ring if something moves while your installing the head.
