Question 1

Is Greddy the same as Trust?

Accepted Answer

Yes. The company is officially Trust Co., Ltd. in Japan. The Greddy brand name is used internationally (including North America). The two names refer to the same company and products, just different geographic branding. The Greddy name has more recognition in the global tuner community.

Question 2

What is the difference between HKS SSQV and Greddy Type RS?

Accepted Answer

Different design and sound character. The HKS SSQV has multi-stage venting and a distinctive "psh psh" sound. The Greddy Type RS has a single-stage design with a deeper "psh" sound. Both are atmospheric-venting and high-quality. The choice between them is largely preference, sometimes nostalgic.

Question 3

Are Greddy parts widely available?

Accepted Answer

Yes, in North America and globally. Greddy products are sold through specialty performance retailers, online stores, and the brand authorized dealers. Major Greddy product lines (intercoolers, exhaust systems, BOVs) are well-stocked. Some products require ordering from Japan with longer lead times.

Question 4

Does Greddy make engine swaps?

Accepted Answer

Greddy specializes in performance parts (turbochargers, intercoolers, exhaust, engine management) rather than complete engine swap kits. Many engine swap projects use Greddy components in conjunction with other parts. The brand engineering focus is on optimizing existing engines rather than transplanting different ones.

Question 5

Is Greddy still relevant in modern tuning?

Accepted Answer

Yes. The brand has continued to develop products for modern Japanese performance cars (GR Yaris, Nissan Z, Toyota Supra A90, GR86) alongside maintaining its lineup for older JDM platforms. The cultural significance from 1990s and 2000s tuner culture has helped maintain brand recognition into the modern era.
