Some of the basic's, boost, oil, coolant gages, scan master(to tune and monitor knock) K&N filter(ditch the filter housing), gut the cat or put a test pipe with a cut out in it's place, good dual exhaust from there back, walbro fuel pump/hot wire kit, bigger injectors, razor's alky and a turbo tweak alky chip.
Good Luck with whatever you decide to do. I bought my car new way back in 2-84, it's still fun to drive.....
