Description

The On3 Performance (1987-2004) Mustang Coyote Swap Complete Turbo System offers a comprehensive solution for enthusiasts looking to boost their vehicle's performance. This T4 version is engineered for a precise fit, with headers crafted from durable 304ss thick wall tubing designed to clear UPR/Team Z k-members. The system includes a 2.5" 304ss merge pipe feeding into a T-4 flange, a 3.0" turbo exit stepped to a 4" downpipe, and offers choices between fender exit or through-the-k-member configurations. The system addresses common challenges with electric power steering by recommending a Volvo S40 electric power steering pump, which can be plumbed into the hydroboost system to maintain both power steering and power brakes. This thoughtful engineering ensures that while maximizing performance, practicality is not entirely sacrificed. Each kit includes essential components such as On 3 Performance Forward Tubular 4 into 1 Turbo Headers, a 7875 Turbocharger (with various other turbocharger options available), a 60mm Race-Gate wastegate, a 3" bar and plate intercooler, and a 50mm blow-off valve. The package is rounded out with a merge pipe, downpipe kit, complete cold side tubing, aluminum coolant tubing, coupler kit, stainless T-bolt clamps, and complete oil feed and drain kits for the turbocharger, along with stainless steel V-band clamps for the exhaust. Many users have reported achieving quarter-mile times as fast as 8.3 seconds in full street-trim Mustangs with this system.
