Sea doo trixx trying to build a bullet proof turbo set up


ok i was thinking motor swap but i am going back to turbo but i am looking for a few parts to make sure i can get the reliability as good as posable. mostly what size and pitch threads are on all of the head and bottom end bolts so i can get arp studs along with stronger valve springs and valves. and i know this is properly nerdy i am sorry. thanks for reading.
