We have a 2T on a race track and we want to increase the compression ratio. The std starter has been playing up and if we increase the CR it is really going to take punishment. Understand the 1G reduction starter fits onto the 3T/2T bellhousing am I correct or do you have to use the 1G bellhousing as well ?

Can anyone help with the part number on a 1G reduction starter please. Tks.
