I was wanting to know how i can make a twin turbo set up i just bought a Borg Warner S400 turbo and i would love to make a set of twins over my hx-35.. any ideas or the specs on how this is done thanks!... or could i just put the s400 in place as a really big single and get rid of the hx-35.. what type of down pipe would i need for the s400??? and would it work???

 

Well, for your COMPOUND turbo set up, there is some work to do. Replacing the HX35 with the S400 isn't an option, it will never spool. I have a HX35 over S400 set up and it work very, very well. I built everything myself, except the hot pipe. I had a welding buddy of mine do that.

by any chance do you have the specs on all your piping? i would love to do the same setup!!! and was it a big headache??
