Those into turbo conversions know that there are no decent RHD turbo manifolds available and you're most likely going to have to make your own or compromise a LHD manifold.
I have finally found a cast iron RHD manifold for my own E36 compact S50B32 project... but E46, E90 and E92 manifolds are also available.
If anyone is interested - PM me and maybe we can do a group buy??
They're not cheap so don't expect eBay prices. They are top qualilty and guaranteed.
Prices depend very much on the quantities as shipping and import duties have to be added on top.
