NotEnoughBass Posted June 9, 2011 Report Share Posted June 9, 2011 I have 1998 jeep cherokee classic with the 4.0 L inline 6. With the aftermarket intake and exhaust im making about 200 hp 240 torque. im on a pretty strict budget but I want to get a little more out of it. It is my daily diver but I don't really care about gas mileage. Any ideas on how I can get a little more outa this thing? PS: I don't like drag race this thing except for friendly street competitions. I do a little bit of offloading but other than that its a daily driver. 1998 Jeep Cherokee Alpine HU Crunch Powerone 300.2 mid/highs + AP15001D bass Soon to be two OA18s Cadence coax and sony tweets Big three + All 1/0 wire Optima Yellow Top No hating on my ghetto system plz.

jconnway Posted June 13, 2011 Report Share Posted June 13, 2011 Cold air intake. Bigger throttle body. TB Spacer. Intake manifold. Thermal gaskets. Fuel Injectors. Pistons. Pulleys. Headers. Full Cat Back Exhaust. ECU Tune. Thats a basic list of things you can do to a naturally aspirated engine to bump up power. Its also the list of things I'm doing on my car. Start with a cold air intake. Full Pioneer Build 4 Per Door - Front Door Build Up Link to comment Share on other sites More sharing options...
mr.p Posted June 13, 2011 Report Share Posted June 13, 2011 after exhaust and intake your making about 140whp if your lucky... you need to either stroke it (lolz) or drop in a SBC DCAUDIO BALLS DEEP Link to comment Share on other sites More sharing options...
white4d96 Posted June 14, 2011 Report Share Posted June 14, 2011 Good cheap way to make the car breathe a little better: Take a dremel and port out the intake and exhaust manifolds so they match the holes on the gaskets. Just take care not to eat through to the outside. I tend to go easier on the exhaust because with the heat it sees it will be more prone to cracking if you go too thin. You can also try porting the head as well, but don't go crazy or you can do more harm than good. What exhaust setup do you have? On many cars the exhaust manifold(s) and downpipes are BIG restrictions. Don't go cutting your cat off; on a 600hp SBC, cats rob less than 5hp. Stepping up 1/4 to 1/2" on the tubing diameter can make a huge difference. Going too big will hurt you though, particularly down low. As for intake, as much air as cold as it can get. Keep the filter high so mud, rainwater, snow, etc. don't get sucked into the motor, unless you like swapping engines everytime you drive through a puddle. If you have to put it down low, find somewhere where your tires and cars in front of you won't throw shit into the filter and where it won't get submerged if you drive through mud and shit, or use a filter sock (I believe is the right term.) NONE OF THIS WILL MATTER WITHOUT A GOOD TUNE! I DON'T MEAN THOSE STUPID EBAY CHIPS THAT CHEAT THE IAT SENSOR INTO BEING COLD ALL THE TIME! THEY DO NOT DO NOT DO NOT WORK! Get your car dyno tuned by a REPUTABLE shop! You may gain like 5 peak hp, but 50hp where it counts. I've seen it happen. All else fails, I've heard the 4.0's like boost =P Too many projects, too little time... Link to comment Share on other sites More sharing options...
