2003-4 Nissan 350z Twin Turbo System Installlation Manual

This installation must only be performed by a competently trained technician possessing the factory manual for this vehicle and all of the tools and knowledge required to safely and successfully complete this specific work. This turbocharger kit has been engineered to provide the highest level of reliability achievable in an aftermarket upgrade and relies heavily on the ability of the installer to achieve this. If Jim Wolf Technology, Inc has not previously trained the installer on this installation, it is recommended that the qualified installer contact JWT before attempting this work.
Installation Steps - Perform the following preparatory work:
- Insure that the fuel tank is less than ― full and that it contains 91 or higher octane gas.
- Safely support the vehicle off the ground for easy access under the car.
- Disconnect the battery ground cable
- Remove the body nose from the car.
- Remove the plastic air deflector shields under the engine and radiator area of the chassis.
- Remove the air filter, air scoop,, MAF sensor, and the intake tube to the throttle.
- Remove the plastic engine shroud on top of the engine.
- Remove the plastic coolant recover tank and hose.
- Remove the windshield cleaner reservoir tank.
- Remove the cross member support assembly behind the cross member.
- Unbolt, but don’t remove the steering rack, just pull it down slightly to get around it. Mark the steering shaft coupling and disconnect the shaft from the rack. Do not rotate the steering wheel during the time this is disconnected. This can damage the spiral cable in the steering column.
- Drain the engine oil and coolant.
- This is a good point to install the colder spark plugs recommended earlier.
- Remove the upper radiator hose and the metal water pipe it connects to on the engine.
- Remove the metal heater bypass tube from the left side of the engine.
- Remove the oil dipstick guide.
- Remove the alternator and starter wiring harness support brackets and discard them.
- Loosen the AC drive belt and remove the air conditioning compressor-mounting bolts, but leave the compressor in place. It does not need to be discharged or removed completely.
- Remove the catalytic converters and exhaust manifolds (unscrew the O2 sensors). Retain the metal gaskets, as they will be reused.
- Remove all upper 6 exhaust manifold studs and the right lower rear stud from the heads. Shorten them by 2 threads to clear the new manifolds and reinstall them. Use 2 nuts tightened against each other to avoid damaging the threads during reinstallation.
