I have an S2 Rs turbo which has the following mods chip, -31actuator, Piper T285T2 cam, K&N, Mongoose Full system, Front Mounted Intercooler. I want to be running a bit more power somewhere around 200 ish mark. Im not sure whether to go for a different Turbo or get head work done. I was wondering if you guys could suggest which one of these would give me better performance results to get the power that i want.

Any help would be appriciated.
