How hard is it to swap a stock HY35 to a Piers HX40?

I know the output size of the hx40 is 4" and changing the stock exhaust to a 4" when you make the turbo swap is a good idea, and I will do that.

I think they make a 4" turbine outlet pipe for the HX40, but most of the 4" exhaust kits have the necked down turbo outlet pipe. Do they make a 4" exhaust that will mate to the HX40 directly?

How hard is it to swap the HY35 to a HX40? Just the obvious exhaust manifold bolts? How does the HX40 hang?

What about the oil line supply? What about the oil line return to the engine? What about wastegate? Where would you put a post turbo pyrometer?, and a C clamp type or a 1/8" threaded type and where?

My boost gauge goes to 50psi so that should not be a problem

Thanks for the help
