Hello, my name is ken and I have an old 1993 dodge intrepid that I got as a gift for my 17th birthday and i was wondering if there is anyway to give it any more power. I have considered changing the air filter to a better brand to give it some extra horsepower but i was hoping for a more substantial increase of about 25+ horsepower. Is this possible? thank you *I have NOT found any cold air injection kits for my carHow do i add more horsepower to my 1993 Dodge Intrepid?You find a forced induction application for your engine or go custom. You will never be happy buying exhausts, intakes and other bolt on wastes of money. The only people that recommend them are people that try to justify their own wastes of money.How do i add more horsepower to my 1993 Dodge Intrepid?If you want more horsepower, and money is no problem, then tear the engine out of it and throw in a nice new Hemi. The newer hemi engines can shut off four valves when it doesn't need to use too much torque so that you can get thr gas mileage of a 4 cylinder, but of course, that's if you have money to blow. ^-^How do i add more horsepower to my 1993 Dodge Intrepid?nope you most likely wont even notice the change from the air filter unless the air filter right now is very dirty
for 25hp increase you would need about an exhaust, intake, and changing to diamond spark pugsHow do i add more horsepower to my 1993 Dodge Intrepid?intake, exhaust, tornado, performance chip (if they even make one)How do i add more horsepower to my 1993 Dodge Intrepid?There really isn't much you can do or should do to boost power output on an early 90s FWD Dodge. The first barrier is that it is speed-density (MAP) based fuel injection and not mass air (MAF) based. What this means is that any mods have to be done before or at the throttle body.
If you do anything that disturbs the volumetric efficiency of the engine such as port and polish, performance exhaust, cam swaps, forced induction, etc. the reading from the MAP sensor will no longer accurately tell the SBEC how much air is going through the engine and so it will inject the wrong amount of fuel which will make the car run like crap. To see what i mean simply remove the muffler(s) and try to drive the car. Upon going from closed (idle) to part throttle from a stop the engine will kick and sputter and have no power for a few seconds then it will catch and take off normally. This happens because lower exhaust backpressure also means lower intake pressure (deeper vacuum) which tells the SBEC via the MAP that there isn't as much air going in as there really is so it doesn't inject enough fuel and the engine runs lean and sputters until the O2 sensors tell it otherwise. Once this happens the SBEC richens the mixture and the car takes off.
To help as much as you can there are a few things you should do. If it is a 3.5 engine find out when the timing belt was last replaced as an old stretched belt retards the cam timing somewhat which reduces horsepower. If it needs to be changed do the water pump and the tensioner pulley at the same time.
Make sure the O2 sensors are the proper Denso ones and not Bosch and make sure the spark plugs are either copper or double platinum as you aren't supposed to run single platinum on a coil pack equipped vehicle because half the plugs fire with reversed polarity and will wear out faster than the other half.
Change the transmission fluid and filter using only ATF+4 fluid. It must say ATF+4 and MS-9602 on the bottle or you will be replacing the transmission (42LE) soon and it will shift poorly while it does work.
Make sure the engine oil is the proper 5W30 as heavier oil will reduce horsepower and MPG due to the extra drag.
