I have been looking around for hotpipes for the hx35 to the s400 turbo. I was wondering which to get I'm confused on which is better. Some are machined for wastegates and others are divorced. Aside from that they seem to be pretty expensive. I don't want to spend an arm and a leg on buying parts for plumbing a twin setup. But right now its looking like its going to cost right at about 2grand if i buy all the plumbing from online sources. Maybe one of you guys knows of a better route to go???

 

make it yourself out of a schedule 40 90 degree bend and then machine plates for the exhaust housings

 

Ok but whats the deal with the waste gate pocket or divorced waste gate?

 

the machined valley is if you use an exhaust housing with an internal wastegate (not recommended) or the divorced/external wastegate

 

well i just want to rebuild my stock turbo and use it. So don't use either of those set ups with the hot pipe, just make it straight thru, no waste gate setup on hot pipe? Is that what your saying from my understanding?

 

to run your stock housing youll need the wastegate valley macnined in but the problem with that is the wastegates on 35s are vary ineffiecent they only route exhaust from 3 cylinders around the turbine

 

so it would be better to get a non waste gated housing and run an external waste gate? Correct

 

yes
