Depends on what other mods your going to do as well, but they should give you 375-395BHP with some good quality supporting mods…
You could then upgrade to some…
13T’s will give you a massive midrange that is far in excess of what others will do and quite a few customers have seen 24psi on them with zero knock, which in theory should give you high 450+ BHP
Early Mk.1 TT’s and most N/A’s have the same brake setup (my Mk.1 TT currently runs a full set of discs and refurbished rear calipers removed from an N/A). From around mid-1992 the TT got bigger front brakes and the rear calipers switched from single-pot sliding to twin pot as well as the disc size increasing.
