I would think that you will be all set with those tranny parts. The intermediate is one of those things that is borderline for your build. I have seen guys break them with stock turbos doing hard launches and I have seen guys that run hard and dont have any issues. If it were me, I would do the intermedate while it was apart and be done with it. Peace of mind more or less if you are paying someone to do the trans build. That is my $.02 on the deal.
