I would get a HKS actuator, that way you can run a bit more boost, about .8bar (just before fuel cut) Obviously you will need a boost gauge to keep an eye on it. Then I would get a manifold and while fitting it get the turbo off and port the wastegate, will give you stable boost and better delievery plus you will have less chance of boost creep meaning you could run a front mount filter. Then just get a FMIC and thats the breathing side of things sorted, should see 160 brake or maybe a bit more then Thats what I got to do this weekend!!
