being you got a n/a engine theres not a whole lot of gains to be made easily for that engine.
a fuel filter from a local parts store is just fine. get a delco o2 sensor.
depending on the condition of your tranny fluid you could also service it as well. filter and new fluid runs about 50 bucks. dont flush it, just drop the pan change the filter add 8 new quarts of new tranny fluid. you could add a shift kit while doing the tranny service, they help keep the tranny a live a bit longer. some one found a transgo for like 40 bucks on line. cheap and easy enough to add yourself.
