View Full Version : bigger manifold
I am building a holden 202 (bue) motor, an i am considering fitting the EFI off a VK motor and I would like to known if anyone known where I could get a plenum of suitable capacity(bigger then the stock one) made?
Is there a place in brisbane or on the sunshine coast that does this kind of work?

How big are you going to go? Ages ago I read something about plenums should be 1.5 times engine capacity (for best performance)....which gets a little hard on a 3.3...they want to have one that is 4.95 L. You could cut one off a different manifold and stitch them together or just have an engineering shop weld aluminum tube to the runners...but I have never seen ally tube big enough.
