Artec T4 Turbo Exhaust Manifold

At ARTEC we have revolutionised the turbo manifold industry with our industry leading SUS347 stainless steel investment cast manifolds. All of our manifolds are engineered and designed from the ground up, CFD simulated and, most importantly, tested in the real world to achieve maximum flow and heat dispersion. The cast stainless construction allows us to maximise flow and efficiency by having smooth merging angles and eliminating any restrictions from tight radius bends or runners.

The result is a truly optimised manifold with consistent performance, resistant to heat pooling and cracking, plus a beautiful smooth exterior finish. Designed and tested in Australia, backed with a lifetime warranty.

Our 1JZ Non-VVTi manifold is a split pulse T4 design with a single 44/45/46mm wastegate mount. It uses 36mm ID for the runners made from the same 347 Stainless Steel all of our manifolds are made with. We went with a single wastegate design to keep costs down as well as keeping the divider continuing almost all the way down to the wastegate mounting surface. This makes it easy if you want to have it divided or non divided, just simply weld in a piece of material. We do not feel this is required.

This design allows for turbos ranging from G30 all the way up to G45, or with PTE from 5858 through to 7175's and larger.
