Just cos something's rare doesn't mean it's worth lots of money. 115 total import does mean they are properly rare though (not Rallye rare)!
How much power can them there synchro boxes and diffs handle then ?
Tsk.
Rod-change Syncro 'boxes can do about 100-110bhp before spitting their dummy pretty quick. They suffer from the normal 2nd gear crunch and self-machining rivetted crownwheel.
I saw a couple of guys with a rod-change Syncro with a 20VT conversion at Combe in 2007. They were dead chuffed with it. 'Is it on a cable-change 'box?' I asked. 'nah, rod-change is fine' came the response. It had to be towed off the track a while later - first time out after being built. The gearbox had gone pop.
Cable-change 'boxes from the Syncro Passat won't be easily upset by +250bhp.
Rear axle (same on Rallye and Syncro except for a few detail differences) can do 250bhp.
If anyone wants a Syncro rod-change gearbox I have three in my outside store. All good (for up to about 100bhp).
