Pontiac Sunfire Accessories and Modifications



  • jsakjsak Posts: 7
    2.3 or 2.4 is common and a possible swap i myself have the 2.2 with cold air msd coils denso iridium sparkplugs and accel wires. you can get chips for them depending on the year there is the intake air temp mod which works good what it does is trick your motor into thinking it is getting optimal air tempature(32degrees) at all times and it advances your air/fuel and is as easy as replacing your iat sensor to a cooler place as far as swaps i would like to see maybe a sunfire with a 3.1 in it? come on do something different the old school cavs and sunbirds had em why cant we? maybe even a 3.4?
  • Ok so i got a 2.2 coupe with a custom cold air intake, some basic interior modifications, blue led strips on each side of the center counsel near the floor, some blue leds on the ceiling, old pontiac trans am rims (which dont laugh cuz they were only like 30 bucks for all four and they look sexy so....) xplod amp xplod 12 inch subs and xplod door speakers and soundstorm 6'9" in the back. (plus 2 tweeters in the front and back in addition to the factory ones). So what i'm thinking of doing next is maybe a cherry bomb (glass pack)...what do you think? Afraid it will sound too ricy or two loud, to be honest it sounds really good with the Air intake right now but its not the sound i'm looking to upgrade its the hp im hoping for. Keep in mind i don't want to put too much money into its basically just my little go kart (for when i want to screw around)/winter rat. Also thinking bout getting a strut bar, how much does that actually help plus is it hard to put in I've never really looked into them.

    i dont know about a glass pack but how about a flowmaster or dynomax something that is quiet yet powerful i have had my sunfire(S) with exhaust done and loved the power gains from it but didnt like the cops following me around so yes go for power but keep it quiet? sounds like a plan to me got any pics?

    To take the window handle off theres a metal fork like tool, you can get at any car store. You just need to make sure its the tool for GMs. Thats the easy part. Theres 2 parts to the door panel, you just need to take off the bottom half to get to the speakers. Theres 4 screws you need to take off at the bottom and snap off the plastic clips between the two halves. i have a 2000 with manual windows so i don't see it being much different than yours.

    I got a K&N cold air intake and im pretty impressed with it, and it gives a little better gas milage. I didn't get an exhaust cuz i don't think its realy worth the money to put on a sunfire, but just remember with cars you get what you pay for. Masterflow is a good brand for exhausts and check Summit for stuff
  • I purchased a used 2004 Sunfire. Am interested in installing a cargo net in the trunk. This one came without it and I know there is one somewhere.

    Anyone have any ideas on where to get one complete with hooks and hardware? Please advise. Thanks
  • I have a 1999 sunfire 2.2. Can I put a 1998 engine in it? Looks like things could be changed over that arent the same but when I am done will it start? Coil pack is in different spot and head is a little different.
  • putting a silencer in ur exhaust takes away power.
    louder is better sounds great i love my car...its an 05 sunfire done quite a bit to it.
    just needs turbo lol
  • man u can make any car a race car ...i could get my sunfire to like 400 hp with the right parts so that isnt true.
  • i gotta 99 pontiac sunfire gt with 2.4L twin cam i put a vibrant cold air intake on it n i had my friend put on long pips. If anyone knows were i can get a supercharger that would b great.

    I have recently bought a 1997 white pontiac sunfire and im in the middle of ricing it out, and I have realized that the front headlights r just ugly.... is there any place where u can buy projection or aftermarket headlights for the 97's :mad:

    Can anyone tell me if its possible to stick a 3.4L V6 or 3800 V6 in a 1998 sunfire gt without doing too much extra work. I know i would probably need at least a ram air hood but im trying to keep it as cheap as possible.

  • yes you can the parts are the same from 96'-99'
  • i would like me car to accelerate quick an efficient i would like my handling/cornering to work the best it can, i would like my fuel economy to be as high mpg as possible, with the highest HP as possible without sacrificing fuel economy

    Any tips?

    Answers Appreciated

    What you're hoping for just is not possible in the real world. Every change you make to the motor has a downside in another area. The real power increases are made by pushing more fuel/air mixture into and pulling more burned gases out of the motor. Now I think you are smart enough to be able to understand that pushing more fuel into and pulling more gases out of a motor cannot result in using less fuel. It will use MORE fuel. This is why race cars get absolutely terrible mileage. So you need to sit down and decide what you really want. If you want power; plan to pay more for fuel and pay far more for repairs (more power will put greater strain on all the driveline and engine parts; and they WILL BREAK). If you get serious about power; you'll probably run out of money for school, so you'll have to drop out of school. The first thing that will probably break is your automatic transmission; which will probably cost $2000 or more to repair.

    It is inappropriate and downright foolish to try to hop up a car with over 100,000 miles on it, that has an automatic transmission. This automatic was not designed to last much longer than 100,000 miles to begin with, let along to be used in racing; so as soon as you start putting more power through (or even often driving it aggressively); you'll blow the transmission.

    If you can't afford to have a major unplanned expense wreck your life and educational plans; wake up and stop dreaming. Leave this car alone, or it will soon turn into a pile of abused junk. I speak from experience; after having destroyed every vehicle I owned when I was a youth; by hopping it up and driving it hard. Only after I got into a situation where I really had to have a car that I could depend on every day; did I learn to become mature and responsible enough to quit destroying the vehicles I owned by playing with them. I eventually realized that I was not rich enough to buy all the parts and make the constant repairs which are part of the everyday life of a hot rodder; so I then got into economy tuning. That finally was a place where I could modify my engines without damaging them (as long as I didn't set the mxture too lean; which is a constant temptation for inexperienced people who try economy tuning). So I then burned the valves out of some of my first cars in that era before I learned that lesson.

    There are some unfortunate people on this site who feel the need to lie about the power and performance they have added to their cars. Be warned not to take all the claims seriously about gobs of horsepower which you read here.
  • I am going to be selling my sunfire but need to replace the front speakers. Can anyone tell me what size I need?
