use a early carb and rejet , the later ones had much less cfm flow , remove egr valve and block off , most likey clouged up by now , good exhaust system in order , you can use the tube type manifold off a ford ranger or the cast one off a last of the 2.3 rangers , toss the cats if you can , depends where you live , you can cheat buy removing the whole thing and tow the car to a muffler shop and tell them you want a exhaust put on , last is remove the cat sticker on the door jamb that say it has one , should be good to go
