This manifold uses 33MM ID runners along with reduced runner length to aid in turbo response and a reduction in lag.

It�s a Reverse Rotation design that uses our innovative universal V-Band mounting system, so any Reverse Rotation 50-55mm V-Band turbos can be mounted up.
The wastegate along with most of our other manifolds are designed to accommodate 44/45/46mm wastegates. In the case of ever needing a larger gate, the internal design of the wastegate runner can accommodate 50mm or larger gates.

People can run this on their RB20, RB25 or RB26 head. The manifold allows turbos from as small as G25 through to G35-1050 and from PTE 6266 and 6466.
