Would a loss of boost occur if there is no gasket in between outlet of turbo to downpipe?
so basically downpipe flange bolted to turbo surfaces
Nope because that is post turbo. If anythnig the exhaust leak might even give you more power? 
Eh… I’d still get it fixed even if it provides better power.
Where can I get a good gasket for manifold to block
Have you tried tightening them down more? If the surfaces on the turbo and downpipe are flat, there is no need for a gasket. chances are the turbo is fien adn your downpipe flange is warped… but I haven’t ever seen a T3 turbo to downpipe gasket anywhere? can make one with exhaust gasket paper, or jsut make one with taht permetx stuff
that would be an exhaust manifold gasket and you can buy them from your local acura dealer
if this is your problem…you are loosing power
Whoops thought he was talkngi about downpipe…
at first I think he was…
that was a different guy asking about the DP gasket.
Ah I hate thread hijackers. Jumps out without notice and messes things up when trying to help :bored:
