I am getting to the point where I am going to start upping the boost on my 1.8t setup. I have the boost control on and running well at 15psi and the engine/drivetrain has held up well for the past 5 years running 22-25psi with the previous owners.
I am looking to get a set of gears as a backup in case the transmission in the syncro decides to grenade, is the gears out of a O2A/J interchangable with the O2C? Is there any fwd gears that are? I would ideally like to find gears that work and are similar if not the same, and get them cryo treated to hold a few more hp, without dropping the coin on a full custom set of gear haha
