Pipe inside up-pipe - porting
got the up-pipe off today! and looking down (from top) I can see a smaller pipe inside! how do I go about smoothing airflow here?
cut notches and fold back????
leave alone???
I guess I best not port top side as I don't want to take turbo off and port that also!

Looked like a total nightmare, any tips?

one of the bolts topside is really awkward to get to! - and mine rounded off (be carefull)
It took about an hour and a half to carefully chisel through nut to get it off
then when it's all loose (this is with manifold already off car)
I had to undo one engine mount and jack the engine up a bit on one side to allow the pipe to be wiggled down (not too bad a job)
anyone got any info on porting topside?

I didn't port the top of the up pipe as I don't think it should be done. The entry to the hot side of the turbo can be enlarged though.
I have pictures of this on my project thread.

There are good gains to be had from a purpose designed up-pipe to match the porting of the headers.
