Tomei Titanium Exhaust 350Z
After nearly 2 years since we first brought you the information, this exhaust and a new Y pipe are available for purchase.
It’s no secret that as cars get older, stuff needs to be done. While driving recently someone stopped me to say my brake lights weren’t working. Definitely not cool and totally dangerous. What I came to discover was that in the daytime, they would not work at all. None of them, not even the third brake light at the top of the hatch. However at night, when you turn the headlights on, the top third light worked fine. Tail lights always worked too, they just didn’t get brighter like they should when you step on the brake pedal.
The culprit turned out to be a simple fix. The factory brake switch had gone bad. After 10 years its to be expected I guess. This switch is mounted to a bracket above the brake pedal, under the dash. Kneel on the ground with the door opened and its simple to see. The switch itself is around $36 at the dealer (we sell em for $18 if you need one). You will see two sets of plugs. The brown colored one is the ACSD switch which is for cruise control and some other functions. The black one above it is the brake switch. It’s a simple device. There is a pin in the center of the switch. Step on the brake, the pin is released, and the brake lights illuminate. Release the brake, the brake pin is depressed and the brake lights are off. Imagine how many times this pin has gone back and forth during its lifetime, and its no surprise that eventually it needs replacing.
While kneeling on the ground grab the switch with your hand and turn it counterclockwise 45 degrees. This will unlock the switch from its holder. Once removed, depress the tab on the top, and the switch is separated from the wiring harness. Plug the new switch in, insert into the plastic locking grommet in the bracket, turn 45 degrees clockwise and viola, you’re done. It literally takes 45 seconds to do.
As wonderful and robust as a 350Z is, like any other car, it’s got it’s share of quirks. The very early cars has transmission issues (solved by Nissan with later revisions), some of the interior stuff is easily scratched. Revup engines are widely known for oil consumption issues. So it goes – every car has it’s faults. One area that is of particular concern for Z33 drivers are the front bushings. The stock bushings are a soft compound rubber, designed for comfort vs longevity. Even on bone stock cars, they are known to start going bad in the 30k mile mark. Add in lowering via springs or coilovers, stiffer spring rates, and wider, heavier tires with lower offset wheels, and the weak factory parts become even more taxed.
The compression rod bushing is an area of particular concern for the 350Z and G35. This horshoe-shaped, aluminum rod makes up part of the front suspension, sitting between the front crossmember and the hub. It features a bushing on one end, and a ball joint on the other. The balljoint is quite strong, and hasn’t proved problematic. The compression rod bushing is another story altogether. Nearly every G35 customer we’ve got has replaced these at least once. 350Z guys also have this part fail over and over. For some reason, Nissan sells a replacement compression rod bushing on the Infiniti side (via part # 54570-AC70A), but not on the Nissan side. Some claim this bushing is “revised” from Nissan. We’ve never found any tangiable evidence that that’s true though. In the aftermarket, for the longest time, the only offering was SPL’s solid compression rod bushing kit. A terrific piece indeed, but really more suited for track use vs street use, as it can be sort of noisy because of the location. Not to mention, so many people have already replaced their lower control arm bushings (inner and outer) with the Whiteline Urethane pieces, that fitting a solid bushing isn’t exactly a perfect match from a stiffness standpoint.
NISMO does a version of these as well, but each time we check, they are not available – sort of perpetually backordered. There is another brand, called Armstrong, which is unique in that it’s a solid urethane design. Have not had a chance to try those as of yet. The Whiteline is more of a sandwich approach so installation is simple, though removing the factory ones does require a press.
Last year, Whiteline introduced a urethane Compression Rod Bushing Kit. We’ve sold quite a few, but never had a chance to do a direct comparison vs. stock. We think the picture speak for themselves. The Whiteline bushing is so much more solid vs the sloppy factory unit. It’s also a considerably higher durometer, but not so overly stiff that it isn’t very comfortable on the street.

Torque Solution continues to push the limits of high performance aftermarket products with our “NEW” Nissan 350z & G35 Differential Mount. This system was designed to reduce movement of the rear differential. This helps to improve transmission feedback when shifting, and gives the car a more solid feel under hard acceleration. By replacing the OEM rubber with these solid billet pieces you are able to get rid of the unwanted slop and flexing of the stock units which allows for the power to go into rotating the tires, instead of flexing the rubber. Giving you better feedback, sharper response, more predictability on throttle input, along with eliminating annoying clunking during hard shifts.
– Improved 60fts / e.t’s
– Reduced Wheel Hop
– Eliminates excessive rearend slop
– Reduces rear end float under acceleration
– Solid feeling gear changes
– Street and track torture tested
– Anodized Black 6061 Billet
– Bushing Driver Tool Included to Ease Install
– Lifetime Warranty
– Made in USA
SPL has recently updated their extensive line of suspension components for the S13 240SX, S14 240SX, Z32 300ZX, Z33 350Z, G35, G37, and GTR. These now feature blue anodized titanium hardware shaves even more unsprung weight from the arms, without compromising strength. In addition, bearings have been upgraded to next generation NCT motorsports bearing feature a carbon fiber teflon liner to provide quiet operation, lower friction, smoother articulation and eliminates bushing deflection under load. The injection-molded slot-loaded liner is also self-lubricating and self-cleaning, offering robust reliability for street and track use.

High performance racing engines require upgraded and improved cooling systems for maximum reliability. One important component of the upgraded cooling system is a thermostat that opens to allow coolant passage through the engine and cooling system at reduced temperature compared to the original equipment thermostat. Reducing the temperature by approximately 10 to 15C compared with that of a standard thermostat, the Cosworth LowTemp Motorsport Thermostat improves coolant circulation through the engine by starting the process earlier than the original equipment thermostat.
Cosworth LowTemp Motorsport Thermostats are engineered with the optimum temperature range in mind for high performance racing use as it is very easy to over cool the engine by either removing the thermostat completely or using a thermostat that is not designed for the specific application. Additionally, over cooling can cause engine damage by preventing critical engine components from reaching their ideal operating temperature, altering the required clearances for safe operation. Another important feature of Cosworth LowTemp Thermostats is the ability to precisely control the flow of coolant when the valve opens. Unstable temperatures and even temperature fluctuation can cause severe engine damage and make it difficult to properly tune or calibrate the engine.
When combined with a correctly sized radiator and other high quality cooling system components, the Cosworth LowTemp Motorsport Thermostat will help to safely maximize engine performance by controlling the engine temperature at an optimum level.
Get rid of the slop in your steering rack with these direct replacement urethane bushings. Includes the mounting bushings and center bushing, these urethane versions will eliminate the tired, dried out factory rubber ones. The reward is much better steering feel and quicker overall response.
