I have an hx35 and hx55, and I was thinking about having them put together making a set of compunds. My question is how to get them to oil and wastegate properly.

As far as oil, would it be safe to have some hydraulics lines made with 90 degree pipe fittling ends? They should stand up to heat right? Also does the input line go to one turbo from the block, then the return from that turbo goes to the oil input of the second turbo, then that turbos return go to the actual block? Or is there some type of T-ing necessary?

I am not sure how to get these to wastegate properly, it says the hx55 is set for like 30 psi? I want them to spool to about 50-60psi. Would I actually disable the smaller turbos wastegate and tweak the larger one for more boost? What and how should I do this?

 

i was thinking of doing the same setup on my 96

 

You dont want returned oil from one turbo go into the other, i woul think hyrauilic lines would work ok, but you can buy longer stainless lines to do this also. Where the factory turbo oil line comes out of the oil filter housing, there is another port next to it to connect another line to. On the oil drain situation, you could tee it into the factory oil return in the block, but most of the time, we cut a hole in the oil pan and weld in a bung and use that for the second oil return. Hope this helps you some.

 

Your right, the oil going into the second turbo would be hot. So I'll just do two seperate lines and T the return lines. What about wastegating?

 

just be on the safe side i would get ss braided line, most hydralic shops can get it and aint that much.
