Cheap wastegates wont be anywhere as good quality as something like a Tial. If you were to buy one of the ones of ebay, chances are that it will either creep boost or break. Plus you cant beat abit of Purple Tial tartyness in you engine bay
Mine is also a hks mushroom filter. It sits just behind the front mount.. Abit of a tight fit like but im just gona run some ducting from the drivers fog light to the inlet of the tubby. Will make it look abit neater aswell
