Prior to that I just fitted a full xforce exhaust system. Its off to the tuners next ( not booked in yet) to get injectors, valve springs and a tune. Im hopping for around 300rwkw or close to and just wondering if at that power the turbo needs is it actuator work or something I read. Hi torque seem to think not but Chiptorque seem to think so. Has anyone got similar mods and what was needed only other mod is panel k&n filter Link to comment Share on other sites More sharing options...

Generally, "rule of thumb" is actuator spring is half of max boost. I.e. 14psi Max boost. 7psi actuator. Having said that a lot of people install 12psi Actuators. But doing this means lowest commandable boost level will be 12psi. Best to see what the tuner recommends. He might be able to tune it with the stock spring to your power level. Your biggest problem might end up being the stock wastegate port. Link to comment Share on other sites More sharing options...

Your probably just telling me what I thought and didnt want to hear but oh well it is what it is. Booked in next monday at Real Dyno Performance in brissie for valve springs, injectors and tune but my 3200 worth of work sounds like it may be more in the range of 6500 by the time the turbo gets worked on and intercooler. Was trying to get away with minimal work as I dont drive it hard but sounds like I have a bit more work to do to make it reliable Could I get away with a hdi intercooler or not worth the money, best to just buy plszamann or process west kit? Any other cheaper coolers worth buying or do I need to just fork out the cash? Link to comment Share on other sites More sharing options...

Looks like ive gotta dig a little deeper into the pockets for reliable power in the range im after. Fuel pump turbo work and cooler it is then.
