unless you like and prefer the revised 4EAT SVX automatic, then save your pennies, drive it for a while & do up the 5 speed conversion. So much less to go wrong & much easier to work on manual gearboxes. Just my $0.02, when (not if) the gearbox goes on the SVX I purchased last week. I'll be converting it over to a manual. I'd love to do a 6 speed, but it isn't cost effective. smallcars kit is rather nice.
