ok heres my prob. i got a t25 on an adaptor plate and Hf manifold, my manifold is a wierd one and i need confirmation on what this manifold came off of, its got a 3 printed on the far left runner.... and my next Q is can anyone tell me where to get gaskets for the bottom of my Hf manifold and my turbo flange being mated to the adaptor plate? and i've tried 20 gauge sheet metal too and it dont work too good..

 

Your local Honda dealer should have that gasket
