i have a 91 explorer with the 4.0 SOHC. i want to put exhaust on it, i don't want it to sound like a rice burner. so what i am asking, is what exhaust has the best deep sound. or what setup sounds the best. it doesn't need to be loud, i just want it to sound nice. any suggestions?

I have a 2005 4.0 XLT and I'm looking at different mufflers to install. I like the deep, throaty v8 sound. Interior noise is no problem. I don't do much highway driving so the louder the better. Any suggestions on cat/muffler configurations that I could get done at my local muffler shops for...

Having trouble getting my 95 explorer 4.0 start. The starter is firing and the plugs are also firing. I have no pressure at the shrader valve. I changed the fuel filter and while the filter was off i turned the ignition to on position and can hear the pump working yet no fuel comes out of...

Hey guys, It's my first time on the forum. I got a 2000 Explorer XLS 4.0 OHV. I was recently at the Woodward Dream Cruise in Detroit this past weekend. And I loved it. It got me to want to boost my Explorer. I was wondering what were some of you guys' best performance modifications on a...

:us: I have a 2009 with the 4.0 engine. Was looking for better mpg and have the engine run more efficiently. I added the KKM air cleaner and that increased throttle response and made the Explorer .7 seconds faster 0-60. I then removed the factory muffler and installed a Flowmaster 50 Series...

Hi, I've scoured the forum for a parts list for a stock rebuild for my 4.0 ohv. The engine runs decent with some hesitation and rough idle. I know some would say to just replace the intake gaskets, hoses,etc and be done with it. However, I acquired the car third hand, I don't know how good...

Aloha! I am the happy owner of a 2000 Ford Explorer with a 4.0L overhead cam V6. (I'm not sure if it's single or dual overhead cams.) My Story: I recently popped the seam in the upper tank of my radiator — and went out to purchase a new radiator from a local shop and have my mechanic...

Greetings all, searched the forum for this, didn't find anything so if someone has any info or if this has been discussed help a brother out. Got a 98 XLT V6 OHV, 115K miles. I have a new EGR valve I'd like to put in. I'd fixed my lean codes by replacing all gaskets and vac lines on my...

Hey everyone! I just found the site by googling "Ford Explorer." I look forward to learning a lot about the next Explorer I hope to buy, an '02-'05 XLS or XLT 2WD. I just sold my '98 XLT 2WD after using it exclusively for almost 6 years. It had been in the family for all but a year of its...

Hi All, New member to the forums but have been lurking for some time. I joined to search, and unfortunately came up empty. I have a 97 Explorer Sport, v6 SOHC 4.0 - and am currently experiencing a problem with the drive-line. I guess first of all, I have seen so many threads outlining...

Hi everybody! I'm new on here and am hoping to get an answer about my Ranger. My '90 Ranger has a 2.9L in it and I want MORE POWER!!! But I'm only looking to spend at most $700-$800. My solution is to put a 4.0L in it, but I don't know if the 2.9L's transmission will work with a 4.0L...

I have a 1993 Ranger with a 4.0L OHV engine. It's almost shot, so I want to replace it. From the research I have already gathered, I can assume that with a few change over's a newer model engine out of a 1996 Ranger/Explorer/Aerostar would slide back in nicely. But what about those newer...

I bought a Fully Rebuilt M62 supercharger off of a Frontier on ebay for $124 including shipping. I know they sell the adapter to put this on a 4.0 but my question is, Do they sell those pieces seperately or do I have to buy all the pieces as one kit?

The truck is a 97 Explorer sport with the 4.0 SOHC v6. The engine is completely stock. I bought another truck so this one had been sitting for a couple months, only was driving up and down my road a few times. The last time I got it out it would bog in the 1k-2k rpm range. 2+k range had full...
