An Inlet Manifold for fitment to the X20XEV ECOTEC engine. TIG welded in aluminium and fully internally ground to ensure optimum flow and performance.

The runners on this manifold are to suit the R1 carburettor spacings (Please check your carbs are spaced 77mm - 79mm - 83mm prior to purchasing this manifold). All of our manifolds are designed to mount the carburettors at the correct angle to ensure the floats function correctly in their bowls. Ideal for anyone who has already sourced a set of Mikuni R1 carburettors for their X20XEV engined project. The manifold includes a single servo connection - these can be blanked off if not required, please advise when ordering.

Manifold may also be suitable for other bike bodies/carbs with the same spacings - if in doubt please ask. Angles and lengths can be adjusted to your requirements.

This item is made to order and therefore on a 10 working day lead time. If you require any additional vacuum take-offs adding to the manifold or a coolant connection these are easily added - please contact us.

danST Engineering can make manifolds to suit your application, please see our other items. Fitting kits are also available for connecting your carbs/bodies.
