To me, the answer to this issue is very simple. Just go to your local Toyota dealer and order a new factory hose up. All of the aftermarket ones I have seen as of yet have fit poorly without modification, and if you ever plan on going to a bigger turbo the factory ones hold their resale value better (imo). In fact, I'd check out the classifieds section here- there's usually a couple for sale
When you think about how long the factory hose was in the car and the environment it lives in- the factory hoses are pretty freaking amazing!
