I'm looking to get around 250~275 whp out of the engine as this seems to be the threshold before additional engine management is needed. I'm pretty sure the stock turbo is shot on my car and I want to replace it? Should I look for a replacement stock turbo, CT20b? Can someone direct me on route that won't break the bank? Places to buy, what to buy for a reliable, moderate boost application that can handle 20min stints in HDPE's?
