hello,
i would like to know if the position of the turbo is the same on the 2wd and 4wd manifold. I want to fit a 2wd manifold on my sierra 4wd cosworth and i want to know if i have to make modifications to the downpipe.

Thanks

 

It is not at precisely the same height no, it depends on the system make ?, whether you need to shorten by about 3/4" or lengthen by same.
I know on the scorpion they are "safe" ie no adjustment needed but some are a lot tighter and will need a little adjust.

I have a 3'' mongoose s/s system

 

I'm pretty sure the goose will need altering in length of downpipe for best fit, any one running a goose done this mod please help!!

You'll need to make the downpipe longer if you change to a 2WD manifold.
