4" downpipe vs. K-member clearance..

i have a bmr kmember with the poly mounts and 4" downpipe all the way to the back, took a little clearancing due to the vband flanges, she is tight but fits good

had to grind the AC mounts down and a couple of places on the kmember.

Those pictures helped alot. Thanks!
I am starting to 2nd guess my turbo placement........originally I wanted it in the battery location. Starting to wonder if a center or lower mounting might be better....
Any pros and cons either way?

well for a lower mount you probably want it high enough so the oil can drain back by gravity. i think were i have mine is at the limit (but not so close it doesnt drain as my drains just fine, i wouldnt go lower though)
Howard... you can gain alot of space if your willing to the the Rad support. Mines here is you ever want to come over and see how it was done.... It is a little harder with truck manifolds to get the bigger pipes back...I was able to slide 3" easily..and a manul rack will buy some precious 1/4"s. in some cases (at least on driver side.
Looking forward to seeing the white machine. I used oval and went under.... I wouldnt do it that way again though.

I'm not understanding how so many folks are running a 4". I have a UMI k member and truck manifolds and my mechanic said he was playing with a piece of 3.5" pipe today and said that it looked POSSIBLE, but would be difficult. He seemed to think there was NO WAY he could fit a 4" DP.
Maybe it is the UMI k member??? If it can be done...he will figure it out. He is a master welder and very skilled at building mandrel systems.

Here are two pictures that show the relationship of the 4" pipe and the SPOHN K-member. I need to install the steering rack and see what kind of issue that creates. I plan on going to a manual rack anyway but it looks like I might be indenting the pipe where the rack crosses underneath it. If that's the case I think I'm home free. Please note that the pipe is just laying on the cross member and still has another 1" to move up.
Another idea that crossed my mind was; once the exhaust leaves the compressor housing as 4", why can't I split it back to two 2-2.5" pipes and runs duals back out under the motor mounts???
The radiator support is coming out already but that is not the clearance I am looking for.

also it makes it easier and yields better clearance as you dont have to go under the tranny to route the exhaust to the back.

I made the solution. I am ditching the stock mount on the passenger side and replacing it with a custom fabbed one. I am going to use a .250" plate on the engine and the same on the K-member. I bent a piece of moly roll cage tubing left over from the cage to make a curved mount. The 4" is going to fit like a champ!
Now I just need to decide if I am going to mount the turbo in the center or off by the battery......
Those of you that have center mount turbos......how are you supporting the dead weight?
here is a shot of the new mount idea;

just make sure you install your steering rack before all that to make sure it wont interfere.
then you still have the problem of crossing over the tranny (clearance problems) to get to the back

Getting 4" off the exhaust housing and at least 4' back is a big plus vs. 3" all the way back. If I need to do some reducing near the tranny I might not sweat it. Don't really plan on getting over the axle either..
