2006 Chevrolet Corvette Z06 Twin Turbo Kit Install - Brutal Force

The APS blow-off valves are clamped onto the rubber discharge tube. Unlike your typical import turbo kit, the APS kit actually re-circulates the bled boost-so don't expect a noisy, stuttering overrun like we've come to associate with turbo cars.

The rubber hose clamps to polished stainless tubes that are precisely bent and boxed for a perfect fit and little loss of ground clearance.

The polished discharge tube has brackets that utilize the leaf spring bracket bolts to mount solidly. Some grinding was needed on the front cradle to clearance the discharge tube.

The downpipes bolt up to the APS off-road mid-pipes with copper RTV providing a seal on the flanges. Since there is no high-flow cat option, Howard says he plans to weld up a set of cats as he doesn't take kindly to the funky exhaust smell or lack of emissions compliance. Tanner also elected to stick with his B&B FUSION catback rather than the raunchier APS piece. The FUSION system retains the valving design used on the factory ZO6 mufflers. This enables noise when you want and a civilized ride when you don't!

One of the dry sump oil lines is replaced by the supplied piece to clear the passenger-side turbo.

Bruce drills the holes in the front frame rail to mount the intercoolers and oil cooler.

All three bolt to the frame and to each other using the supplied brackets.

The directions say to put the air deflectors in from the bottom, but Bruce actually wound up putting them in from the top and loosening the bracket bolts. The deflectors are essential to directing and maximizing airflow through the intercoolers and oil cooler, as well as the radiator and A/C condenser.

The intake tube is clamped to the intercoolers and throttle body. If you are wondering where the MAF goes, it's actually built into the Y-shaped intake tube. The APS MAF housing helps extend the MAF range.

The braided stainless steel oil lines are routed as directed and bolted up to the oil cooler.

The last pieces of the air intake tube including the air filters are attached with the hose clamps. The blow-off valves connect to this piece of tube. To fit the passenger side filter, the horn had to be relocated to the other side of the passenger side front frame rail.

The APS wiring harness has three grounds plus power, fuel pump, and oil scavenge pump wires that need to be wired in.

The packaging, as well as fit and finish, speak for themselves. Minimal to no loss in ground clearance, a neat appearance with no second-rate hackery,...

...and no compromise to the function or durability of any factory (or otherwise) equipment.
