Street Spec Value Shortblock

Designed for the low noise and long life essential for a daily driven street application while easily handling increased power outputs and weekend track use. The Street Spec Value short blocks features a high quality Mahle 4032 forged piston set. Standard compression 2.5L short block pistons are custom made to RalliSpec specifications and use the same ring package as Cosworth pistons. Manley H-beam 4340 rods help keep the cost down and are suitable for applications up to 450whp. All RalliSpec Street Spec shortblocks are built to exacting tolerances by a technician with 13 years of experience building Subaru engines for high end motorsport applications. A detailed build sheet is supplied with each short block.
