my friend ordered a BW turbo, they said it was a 3 week wait, 3 months after that they still had no turbo....GL!
This is a small issue, your best bet is it to find a dealer that has what you want in stock, or you never know what will happen.
I know alot of people say things about forced inductions, but i have never had an issue with them, and 9 times out of 10 they have what you want in stock.
However they are incredibly busy people.
Id either call them or rob from modular turbo.
