Hi Guys,

Im finishing rebuilding my 728 e38 52b28tu (DN18544). Right now, the rust is being removed and the mechanical parts are perfect. I decided to install turbo gt3582 to get 1 stage +- 350 WHP.

I've got some questions:

1. I have some concerns about the gearbox. I've got 5hp18 and I think it could be to weak. How can I improve that? Should I change it for 5hp30? I'd prefer to stay with automatic gearbox.
2. I'm planing to make custom inlet manifold. Can I modify the original part? I'd like to weld a prototype. Is the original part made of cast iron or steel?
3. If everything comes allright, I will use Ecumaster det3. Before installing the Ecumaster, I'd like to use a safety valve. Can I use the MBC valve? Where should I put it? Will the inlet manifold be the right place?

Thank you for your help.
