Dammmnnnn thats a lot for an ecu, I linked you to one on your fb only 10 mins ago. Manifold wise, keep it local and go for a Ricky Lee Race Tech manifold, he only lives in Rawmarsh and i'm sure he guarentee's his manifolds for 2 years and they never crack anyway. PM me if your out in the car sometime, would be cool to have a proper look at it, i can also show you what there like with a jdm ecu, then you wont regret having payed all that....
