I getting together the parts to build a set of twins just need to get head studs and a non-gated housing for the 35. I have a 44mm ext. wastgate the HT3B and 90% of the pipe. Question is what size housing a 14cm. or a 16cm. I do what to try and keep the boost down till I get the head oringed I do have two 1/2in. blow off valves.

 

you could run a 9cm housing with that 44mm wastegate and have no problem keeping boost down.
