Stainless Steel Cast Turbo Manifold
The latest in bulletproof turbocharging technology, our kit includes a 347 investment cast stainless steel turbo manifold. The high thermal inertia and excellent heat retention of the cast stainless steel manifold, provides the turbocharger with as much thermal energy as possible raising the efficiency of the system, superior to any tubular fabricated manifold. Lifetime warranty on cracking, precision machined mating surfaces for ultimate fit and sealing, high exhaust gas energy for the best turbocharger performance, no ugly rusting common on cast iron manifolds, our Treadstone 347 cast stainless is the latest in cast turbo manifold technology.

Stainless Steel Downpipe
Our 2.5” diameter 304 stainless downpipe is manufactured to precise standards, and hand tig welded to perfection. The wastegate is recirculated as far from the turbo outlet as possible, this increases wastegate efficiency and keeps you car sounding great. Includes extra O2 bungs for easy wideband hook up.

Cast manufactured 304 stainless downpipe flange ensures proper sealing to factory or aftermarket exhaust system.

The Treadstone mass air flow adapter manufactured for this kit was designed to seal under high boost pressures, and incorporates a bead rolled lip to keep couplers from blowing off and a rubber gasket.

Performance Figures
The performance figures are amazing, at only 5.5-6psi of boost pressure we were able to attain 271hp and 25ltq at the wheels. These dyno #’s were with no catalytic converters, and 3” catback exhaust.
Please view dyno runs below.

Our kit will come with an Apex AFC, one of the best and least expensive way to tune the Nissan spec V. We recommend a qualified tuner to tune the AFC. After installation of the turbo kit, the car can be driven normally, just keep it under 3000K rpm on the way to a tuner or dyno, if needed. We are working with Unichip as an upgraded tuning bolt on for this kit, and will update the site when it becomes available.
