Nissan SR20 V-Band Exhaust Manifold

The Artec Cast SR20 manifold has been designed to accept a wide variety of turbos that use a 50 to 55mm ID on the inlet flange. These include Precision, Tial, and Garrett. The wastegate has been positioned to allow for easy routing for a plumb back or vent to air layout. The wastegate comes fully machined to accept most 44/45/46mm wastegates. The wastegate pipe is also designed to flow up to a 50mm wastegate unit, so you would simply cut our flange off and weld the bigger unit on, if required.


We use 33mm ID runner (others normally use a 36/39/42) to help keep throttle response up, as well as transitioning from the SR20 exhaust port shape to our runner over a length of 45mm to aid in flow.

The design allows for very easy oil and water line routing.

The V-band also allows you to run a straight forward facing turbo layout our pointed out to the side depending on the owners taste and turbo selection.

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.
