Arias Extreme Duty Piston Set Nissan 350Z 2003-2006
Over the past three months, I have been working with Arias on developing an extreme duty piston for the VQ35, that could potentially sustain 1500whp+ worth of abuse, but still be streetable for those shooting for 15-20psi of boost pressure with the current kits on the market.

Designing pistons, much like anything, is all about compromises, and balance. The current Arias piston that we sell comes is made with high silicon AL, which is a terrific material for street driven cars. High silicon AL is much stronger than a casting, but experiences heat expansion that is very similar to OEM cast pistons. What this means to the user, is that you can run much tighter piston to wall clearances, and you have an engine that sounds near stock...even at cold idle. At ZDAYZ, where hundreds of Z owners converge on Deal's Gap in western NC, eastern TN, people were amazed that my motor sounded so quiet....literally just like stock. The Arias high silicon forgings are also very strong, and suitable for 15-20psi of boost pressure on the VQ.

However, in my opinion, as you breach the 550whp mark, more strength and durability is needed. Running a car once on a dyno is one thing, but continuous abuse, for instance, while engaging in road racing, or freeway racing (shame on you) can generate an incredible amount of heat and stress inside the combustion chamber.

So I worked with Arias on developing a custom piston design for the VQ35, that will only be available through ForgedPerformance.com. This piston design is unique in several ways....and will be stocked by us in 9.0:1 CR, and custom CR available upon request.

1) We chose 2618 Zero Silicon Aluminum. This material is roughly 25% stronger than high silicon AL, and about 15% stronger than low silicon aluminum. This is the same material used in most 1000whp+ drag cars

2) The ring lands have been redesigned to be nearly twice as thick on the top land, and about 50% thicker on the second land. More protection from heat and the
