Will my 16G FMIC J Pipe work with a 20G?

So I have what i believe to be a Big 16G turbo setup with a front mount intercooler kit and i am pretty sure I have exceeded it's efficiency at about 24 PSI, so it is time to go bigger.

My understanding is that a 20G will bolt right up to my manifold still and work with my current water and oil lines, But what about intercooler piping? Will my 2 bolt flange style J pipe in the picture below work with a 20G ads a direct bolt on?

Yes I have searched quite a bit and all the threads I have read mention the J pipe but don't give much of a solid answer.

Help...Thank you.

You dont use a j pipe with the 20g. It is a downfiring turbo. Looks like it will bolt up though without a 90 degree coupler on your setup though. If you removed your jpipe, im pretty sure you could get a coupler on to your 20g. No mods needed.
 
So you guys are saying that my current 16G housing will go right on? Thats excellent ...Thanks
 
having a hard time seeing how a downward facing 20G will easily go on without modifying all of the intake piping off the turbo. I guess i have not see one of them setup before.
