Tyrone's 2004 convertible 350z
Tyrone was on his way to ride CrotchOfTheDragon.com Route 622, when on the interstate, a huge rock broke his radiator and lead to a motor failure. Luckily, he was within 10 miles of JGY. Geico sent the car here for a motor swap. We will also be doing some tasteful motor upgrades, as well.

Agency Power pulley kit

Greddy carbon fiber air diversion plate for radiator

Megan Racing radiator hoses

New stainless steel headers

Once we took the motor out, we found out why it moved so much... the left motor mount is broken

Trying to remove the radiator seemed different on this Z... Well, the convertibles came equipped with a 22 pound energy absorber in the front left corner of the bay...

Replacement motor has the oil filter in the front instead of the side of the block

Upon removing the motor, we found this broken driver's side motor mount

Removing Tyrone's RWD oil pans and accessories so that we could install them onto the AWD donor motor for it to fit his car. The AWD version of the VQ motor has the starter on the driver side, where the RWD has it on the US passenger side. Also, the AWD oil pan is larger to accommodate the front axle shaft that runs through it.

Notice the replacement motor is much cleaner inside than the old one

We installed the Agency Power light weight pulleys onto his motor for added power.

We swapped over the alternator and motor mounts from his motor.

We found two melted coil packs from the overheated motor and replaced them.

We prepped the intake for the Blox Racing Plenum Spacer.

The spacer easily installs and provides cooler intake air, better throttle response, and clears the strut bar.

After installed with the included Blox longer hardware, the fitment is great.

Motor is going in. Once the motor is barely in the bay, the headers will be installed.

Dyno work

After dyno tuning with UpRev, we went from the lower 200's in both up to over 235HP and 216tq

With more refining, we achieved a touch over 240HP and 217 tq
