Questions
I've got me an S5 jspec for my car, longblock. Before I was running an s5 shortblock, with an s4 front cover and s4 manifolds/etc. Now I've got complete s5 manifolds available, are they better than the s4 ones? direct swap? I've also got an s5 turbo, they're bigger, right? So I should be using that as well. Anything else that I should do?
Is a rebuilt FD Fuel pump + stock wiring + 550cc injectors + S-AFC = enough fuel for 12-14PSI? What's the "ideal" maximum boost for an s5 Turbo?
How can I make the twin-scroll work again with my emmissions crap removed, what silnoid works it, and do I just hook a vacuum line to that? or what. There is a huge difference in low-rpm power with it hooked up
I'm running a top mount right now, but I think I'm going to weld 2 together and front mount them (infront of the rad but behind the a/c condensor). Where can I get piping? I used old rad hoses for my metro turbo, but I'd like to not go the ghetto route with this car
Thanks...

Not sure about the manifolds. The s5 turbos arent bigger. They have a fully divided exhaust manifold unlike the s4 turbo manifold.. Also the s5 wg was designed better than the s4 one which only had one small port compared to the 2 ports the s5 had. Not sure about the twinscroll. You will most likely have to custom make your pipes.

s4 and s5 manifolds are the same size so just use what bolts up to your motor. for the IC pipeing go to www.atpturbo.com They are great people that usally have ok prices on great stuff. Although there site is down right now for ordering stuff I still like. I am asuming you have 4x550s which will only let you boost up to 9psi. if you get 720 secondairis you can boost up to about 14-15lbs on teh s5 turbo. Everyone will tell you something different when it comes to max boost on the s5 turbo but I think its right around there.
actually its summitracing.com for the IC pipeing but atpturbo kicks *** to.

another thing to note.. the S5 upper/lower intake manifolds sit up higher than the s4 setup.. If you are going to use your S4 top mount intercooler, you may have to be a little creative or else it will sit too high and interfere with the hood..
