downpipe advice
 
I had this on my car running 9 psi on my d15b2 stock block w/199k miles. well now the turbo is off and im getting ready for a new motor. I thought i would just rebuild the downpipe while its off. I saw Road Race engineering's 70 or 75 degree bend and it looks perfect. so besides that i need advise on the upper portion of the downpipe. since the ford motor was designed to point the exhuast outlet and inlet in the same direction i had to re-direct the exhaust outlet 180 deg. like so: (warning not a pretty lookin downpipe and dont laugh)

oh yeah i have an extra exhaust housing from another turbo of the same type so i can do everything new from the start. I also saw road race's donuts is there place or a site i can get them cheaper? thanks

I made a new flange for my Ford sourced T3 outa 1/2" mild. Actually made a template from plexiglass and then took it to a guy who welds stuff for me.

Then welded on a 90' mandrel bend onto that. (added o2 bungs too)
Not to hard at all, (you seem to be handy with the welder :P ) and ends up being nice and clean looking.

i used to use the same manifold and ford turbo that you have now....i just angled the flange on the manifold to aim the turbo/dp where i wanted it...try that, it makes a much cleaner path for the exhaust
