An inlet manifold for fitment to the Vauxhall X18XE1 and Z18XE engine. TIG welded in aluminium and fully internally ground to ensure optimum flow and performance

The runners on this manifold are to suit the Yamaha 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 X18XE1 engined project. The manifold includes a single connection for the brake servo - this can be blanked off if not required, please advise when ordering.

danST Engineering can also make a similar manifold, but to suit the standard throttle body spacings - should you wish to avoid the work involved in re-spacing throttle bodies. Please see our other items or contact us for further information.

Manifolds come complete with coolant connections (where applicable) as standard and a brake servo connection on the runner nearest the gearbox.

This item is made to order and is therefore on a 10 working day lead time. If you require any additional vacuum take-offs adding to the manifold 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.
