You'll need a t3 or t4 tubular manifold for that engine and a 38mm (minimum) external gate to control the turbo. External gates work off of a remote pressure source (compressor housing or IC pipe) which in turns open up a fairly large valve to dump exhaust to atmosphere. When the exhaust is dumped, the exhaust pressure is reduced to the turbine and thus the turbine slows. A slowing turbine creates less boost pressure.
Hope this helps.
