| Underdrivee pulley and lightweight flywheel made the biggest difference to me when I was NA. You can bump the timing up to 17 BTDC as well, but I'd only use premium, maybe only 93, and listen for detonation. Might be better off spending money on suspension mods to help the car handle better and be faster through corners. Practically all of these cars now need most of their bushings replaced, so I'd start there if you intend to keep the car long-term. A TT really is the way to go if you want big power though.
