Sentra GTR-1

Yo dude I myself have a 94 GA16DE......(this is what I have done ever since I bought my car brand new before and during the time that Ive added all my parts...)
- Always change oil every 3,000 Miles (I myself like to change mine between every 500 and 1,000 miles, but thats just me Im picky, pulling out the dip stick my oil looks like light yellow honey its so clean)(the closer the oil change intervals the more gunk you get out of your engine)
-Replace the Fuel filter every 30,000 miles(I myself do it every 15,000)
-Replace your Ignition Wires with fresh ones( I myself have blue NGK wires which I have replaced with brand new blue NGK ignition wires.) I give em bout three years and replace em.
-Replace your Cap, and Rotor and sparkplugs......stay with the factory NGKs! trust me there the best!
-If you have the stock air filter, replace it. If you have a stillen or JWT POP charger....clean it.
have your transmission fluid flushed and refilled ( believe me just changing does not do the entire job, flushing pumps two quarts through the ENTIRE system....flushing out the torque converter as well. Youll feel smoother shifts as well.
-Flush and fill your radiator once or twice a year once early in the year once late in the year.....this will prevent water pump failure and over heating.
-flush your power steering fluid, youll feel that new crisp steering responsiveness that was there from the beginning.
May sound like a lot but really its not that much for getting her back in shape for go fast goodies! hope this helps!
