I am doing a sohc homemade setup (who isnt?) and I have a oyoa turbo and a dsm sidemount intercooler, the exit on the urbo and the entry on the intercooler are very small and I can have aluminum piping made in this diameterr for very very cheap. Will it have any negative downsides? its only like 1.5inches diameter but I thought hat if the turbos exi is the same size it wouldnt help to be any bigger (just like crush bent exhausts dont help much)

 

I'm curious too.

 

homemadeturbo: why not to use aluminum

makes no sense

 

aluminum is fine..

the diameter wouldn't matter too much aslong as you don't step down in size.. and if you do.. not too much.

 

yeah, try to stay at about 2", because the air does expand after it passes through your intercooler. Anything bigger than 2" is overkill at low boost, and anything bigger than your TB is overkill at ANY boost level.

 

DSM sidemount pipe size should work fine for what you're asking of it..
