ok we have a 87 GN and we want to go low 12's. we cant find any proven recipes to do it. what can we do to accomplish this. we want it on pump gas and stock turbo/long block. it currently has 3in terry houston DP no cat with 3in dual torque tech turbo back exhaust. also has injectors (that we dont know what they are and want to replace) has IC pipes and kenny bell cold air kit (with box around filter removed) and a chip (also which we dont know the maker). trans is rebuild as of this past summer with a stock or near stock stall. car has untouched rear end and will be on M/T or BFG drag radial. stock suspension minus poly bushings front and rear. koni shocks, lowering springs, and hotchkis sway bars. want really only bolt on mods possible porting intake/TB. anyonehave ideas of what we can do? the car went 13.5's last year without the DP or TT exhaust, and was on all season tires. so basically 1.5-2 seconds at most is what we want off. thanks in advance
