I just had another batch of the fuel rails with internal dampers machined, and they are readily available. These are machined from solid billet, not extrusion. They have -6 ORB ports at either end, and are machined to accept Nissan G35 fuel damper inserts. Dampers are installed between each injector pair for optimal dampening in a batch fire system (if retaining the stock LH). Fuel rails also have injector retention clips with an anti-rotation feature for the keyed split-spray injectors. Rails are 6061 and satin clear anodized. Retaining clips are waterjet 304ss.
Internal dampers greatly simplify plumbing, as does the female -6ORB port allowing for use with any number of fittings or directly crimped hose ends.
Suggested flow pattern is parallel for batch, and series can be used on aftermarket sequential for even simpler plumbing.
Mounting brackets are available for direct installation on stock 87+ manifolds.
Fitment has also been confirmed by a third-party on the Euro 16v M28/21 engines with custom brackets (not able to test 16v fitment in-house as I have no 16v engines in the collection).
3D model of the standard damper rail (without the S4 mounting tabs) available for viewing here:
