I didn't see anything on their site for premanufactured Honda Trannies. All I saw were the rebuild kits from Stage 1-3 and the TQ stages 1-3. I'm just wondering if there's anything else I can install in the tranny while it's out for the rebuild. Maybe a Quaife Diff would help. But mainly it's wanting to know if I can switch the gears for something longer or shorter or even the Final Drive Gear ratio.
