S4 / RS4 B5 gearbox

Rs has a slightly shorter 3rd and 4th gear

And thats it? no stronger or better internals?
Reason being I'm thinking of taking my S4 off the road in the winter and carring out some serious mods both HP gains and reliability gains. Going to put money aside every week and buy as I go during the summer and then hopefully bolt on all the goodies in the winter. Well thats the plan.
 
Yeah that's what I tell the wife but it won't wash with her.
 
Lol I think with the exception of Sandra no women understands our needs for modding they just do get it.
