I am selling my ITBs. After busting the oil pan on my rebuilt engine I replaced it and in less than a thousand miles it seized on me. I'm looking to swap in a M52TU now.
The ITBs are still brand new and are a direct bolt on piece, replacing the upper/lower intake manifolds. All you need is a new lower intake manifold gasket. I test fit them, but never actually ran the engine with them installed.
I will include a set of freshly reconditioned 24lb injectors, a dbilas t-shirt, and shipping for $1500. they are 1453 euro from dbilas. I can provide more pics to folks with serious interest.
