These came with the twin coil packs from the factory and the different inlet manifold na guys fit. From a google search it says they came with 110ps.
Just wondered if anyone had fitted on to a starlet na?
Your not diverting the air through a T piece it diverts it through the stock boost solenoid.
this is a copy from the hks fitting instructions.
Another option is a JAM Racing actuator which has two ports.
I'm sure when you buy a new HKS actuator (single port) it comes with fitting instructions that show you using a T piece in the line between the turbo housing and actuator to the boost solenoid to retain the factory high low boost function.
