making a manifold and dump pipe.

The exhaust on my turbo has a twin scroll housing, i was wondering do u run 3 cyls into each side, or 6 into the size of the 2 holes? and does it matter if the pipes arnt equal length?

also Ive made a 3" dump pipe off the turbo, where do i put the external wastegate into it, how far down.
The pic shows it going straight out, but in the car it will be 90deg out of it.

Re: making a manifold and dump pipe.

The turbine housing is a "split pulse" housing, you'd be better off running 1,2 and 3 into one side and 4,5 and 6 into the other prividing the firing order is 1,5,3,6,2,4.
This keeps the exhaust pulses even.
