I so much want one of those prodrive inlet manifolds
Hi @rudolfssau that information is from Ades 555 website which I am slowly resurrecting and adding too with help from @type-ra and people I know who own and have worked on these magnificent machines. Please continue to visit it and feel free to comment on in this thread
Great work, some awesome videos, keep em coming!
They were a polished up v1/v2 inlet manifold on the customer cars nothing too special so should be easy to replicate @edsel
"Proper" manifolds were specially cast magnesium......
One of my favourite insights into the Subaru / Prodrive world rally team testing of the 555 Impreza.
