Word on the street is the 3.0l was revised for 2002. I'm still trying to get any new owners to let us know their experiences with this motor. Hopefully Ford has fixed the issues with the past design...

matt--->The 2.5 is bascially a stroked 2.3l. I heard that the dual spark head was for increased power, due to the low cubic inch (140) of the engine. I'd like to see a 4.2l v6 borrowed from the f-150, or even a 3.8l v6 from the Mustangs in the Ranger. The 4.2l generates 252 lbs of torque at 3400 RPM...

i am leasing my Ranger, but i am going to buy it (should have simply bought in the first place, duh).
when i own it, i intend to play with it a little to get more punch from my 2.5 liter.
I added a K&N filter and i am going to also play with my air intake. after it is out of warranty i am thinking of milling down the head to increase compression or maybe getting new heads for it. any suggestions? i would like around 145 or so horsepower to go along with my 23 mpg.

140 cubic inches was for the 2.3l.
Sounds a little pricey for a 4 banger... But if you want the kick, sounds good. An exhaust system might be close to that amount too. Do web searches for 2.3l mustangs and performance parts for them. The 4 banger mustang is kind of the red-headed step child as far as parts availability, but they can be found. (Under drive pulleys, chips, and a few other ideas here and there...)

a new catback system would increase my horsepower by 10 horsepower???
if so i am going to do it asap. any preference as to brands/shops?
also, would such a system damage my factory warranty?

With 20,000 miles (4.0 w/auto), 16" tires and Off-Road gears (4.10), mine gets up to 19 highway (just under 70 MPH) and around 12 - 14 city. That beat the 95 F-150 it replaced (302 V8) with 15" tires and Off-Road by about 2 MPG.

so, i was checking my oil tonight and i saw a sticker i had never seen before. it was under the hood on the "shelf" above the radiator. it said that my PCM had been replaced as of July 12, 2001.
Why would my PCM be replaced? does this hurt anything or help anything in the long run?

Well I run hooker headers and warlock mufflers on a 460 big block, but that's in my 67 mustang. My '93 is all stock, so I don't have any experience in brands. But the brands I know of are dynomax, borla, flowmaster, and bassani, and one of them can probably offer a kit. Just look in a JEG'S or Summit Magazine and you can find other companies that you can try calling to see if they can help you out. If you go the full route (not just cat-back) you will be losing a little (tiny bit) of low end torque, but you'll gain an equal or more amount of higher end HP/power.
The way the warranty thing goes is that if it's not Ford OEM, they won't warranty it, but any other part on the vehicle not affected by such replacement should still be covered. Exhaust shouldn't affect much but itself. I would just try to get to know your service technicians and manager at your dealership. I'd rather have them as friends than just strangers or enemies. Can't hurt asking their opinion and policy on stuff like that.
Sounds like a sticker marking your car to receive a replacement. That's where they stick the R-134 freon replacements, and other stuff like that. Maybe your sticker was a recall or TSB of some sort, or maybe a special repair(if it's a used truck). All-in-all, you should feel better off because it's been replaced with the aparantly correct one.
Here's a cheap and easy way for a little more HP. If your engine seems to have more power when cold, then replace your thermostat with one rated in the 160-180 degree range. This will force your computer into a "cold" loop, and milage may suffer, but your engine will always act like it does after you pull onto your first street in the morning...

i was going to ask you about the thermostat but i forgot to...funny that you should suggest it. thanks for your advice...
also, does it take the computer time to adjust to my mods?
Dec 05, 2001 (6:58 am)
will adjust itself based on sensor outputs. It has a specific datamap of fuel/air/rpm/speed/temperature ratios. Small things like mass or ram air for the Ford small block v8's had different computers. So if you change anything that could affect air/fuel flow or burning, then a computer adjustment would be beneficial. The computer will adjust to a degree, but it's always trying to reach it's default settings. Hence when you put in a lower degree thermostat, the computer will adjust the fuel/air ratio to rich, possibly decreasing fuel milage and increasing idle RPM. While the engine itself runs cooler, there will be less heat for the heater and defroster.
Trick is to try getting all the modifications done, so you know what to tell the company burning the chip for you. But a new exhaust or removing your air silencer and changing filters won't require or really benefit from a chip. Milling heads, adjusting timing, cams, new injectors, new gears, that sort of thing would probably take advantage of reprograming the computer.
Ever think about just swapping out the rear end gear? Installing a numerically higher gear (like .25 higher) would give you better zip, but you would sacrifice cruising RPM a little. It would feel like an extra 20 horses or so.

i considered that...is it a pain in the butt to do? it will also compromise my warranty i bet. it would give me better mileage and more speed, i know. i dont tow much and all i usually haul is the occasional furniture if a friend is moving, fishing rods, hunting stuff, cooler, friends...etc lol
