Default what bends/dimensions are needed for downpipe to clear A/C?

ok, I really don't have a place to weld on my own (apartment), and since the guy that normally does my fab stuff is taking WAY too long I decided to just buy the bends and have a local muffler shop crapweld them together.. so I'm wondering what bends & dimensions i'll need to get the job done.

I know there's a 90* coming off the 5 bolt flange (driver side) which needs to be cut as close to the bend as possible, then another 2 90*'s, one going toward the passenger and the other going back to the exhaust.. could some supply the dimensions maybe? I would be so grateful

btw 3" is preferred

i've got a set of 2.5" mild steel from an intercooler pipe set I'm going to use.. I'll just try to mark everything as good as possible, take it to the muffler shop and hope for the best

turbo is being mounted on the other side now



also, thinking about doing a dsm/audi/volvo sidemount on the passenger side to avoid running all the pipes around to a front mount

the front mount and piping is the least of your worries. that turbo doesnt look like it is going to leave room for the compressor or condenser

thats ---- your gonna have to measure out then. you have a sawzall? mock that ---- up, and mark the pipes how they should be aligned, then take it to a welder.

Better yet take hose clamps, and some steel strap. Mark where you want want everything, Put a clamp on each pipe about 1/2" from the cut seam. Put 3 straps under neith the clamps and tighten them down. Then test fit. Take it to the welder all fitted together and tight that way they cant mess up welding them.

I do this same thing when I do charge pipes, downpipes, headers, etc. Clamp the stuff together then take it to my table to tack it.
