I have a pair of td03 turbos I'm thinking about fabricating into twins, one off each head, but I'm not sure if they will let the exhaust flow enough because they are quite small. Generally the engines with a td03 are about 1.5L in displacement so theoretically it could work. They are internally Wastegated at around 7psi, just over the 6psi I'm running on my impreza with a 1.8L and td04. Fitting and fabbing isn't a problem, just don't want to do all the work to find out they won't work lol. Any thoughts?
