I am guessing that this has been asked 1000 times before, but I am new to the board so please don't get upset if it has. anyway, How expensive is it to convert from an auto to a 6 speed on the turbos. I have been looking at supras and I have been able to find a lot that I like, but they are all auto's and the 6 speeds are much more expensive it seems. I know that you can put the single turbo on the NA, but I also know that it is expensive. Which would be the better choice? put a single Turbo on the non turbo or get the turbo and convert from auto to manual. Obviously I would prefer a 6 speed to start with, but they are all over 20k . thanks guys.
