Had some texts today so will paste in The highlights to save repeating myself.
The dump will bolt yo stock exhaust (but that's dumb)
I will include manifold spacer and studs and a 4 to 3inch reducer for intake
All you need to buy is a 90 degree silicon elbow (will double check size for you) oil and water lines, drain.
I had mine with all stock in engine bay pipework no worries, stock manifold
No sorry no photos of in the car. Theres photos of other guys on sau. Can take photos of dump later tonight. I know people worry about split dump cos a split dump on the nissan flange sucks, but gt30 housing s are different, if you Google it you will see what I mean, the gate is seperate already.
Powe wise depends how hard you push it amongst other things, but 300 at 18 to 20 would be possible on 98
