Hope I'm not resurrecting a dead thread
I have a few questions to pose for the tuners, experts and innovators.
Please see my comments/questions in regard to turbo retrofit for Z4 3.0si.
1- Is it possible to repurpose the (N54)335 twin turbo manifold for bolt on N52 application?
1a- Conversely is it possible to repurpose the (N55)335is single turbo manifold for bolt on N52 application?
From my research theN52/N54/N55 share same block dimensions (different material structure)
2- Is it possible to repurpose the newer (N55) ECU programming for use with the N52? (specifically since it is formulated for use with Vanos+Valvetronic which is a big time FI n52 tuning obstacle) Then add additional piping + low boost tune
I am confident these are the building blocks for single turbo n52 325/328/330/3.0si FI conversion.
