I believe the '96 GTSx4 used zip ties from the factory. Titanium nuts were too heavy.

 

more seriously, are there any low compression 928 turbo's around? or do they just turbo it with the high compression?

 

There is a old euro 84 near my house that for longest time wanted to modify and turn into a gts look a like and add all kinds of stuff to it.....then I matured and realized life didn't have to be so hard and wanted an original looking S4
