looking into building my DD eg hatch w/ gsr. I was wondering on what parts I should use in my build I want a reliable turbo build making 300-350 whp. I am not looking to cut any corners. should i piece a turbo kit together or just buy a complete one? should I build the block or just the head or both for that matter. I know that my gsr stck can handle that power but will it reliably. any advice will be greatly appreciated thanks HT
