[What Cast Manifold Options Are Available?]

For the RB25DET, what cast manifolds are available on the market?

I've seen that there are HKS T4 low mount manifolds, but i want to know if there are any top mount cast manifolds.

I'd like to use a GT30/40 turbo, so preferably a T3 style flange.

Thankyou.
