wanna get a discussion going on this subject based on personal experience. people are starting to crap on the 4.0 i-6 compared to 4.0 v6. i love my i6 but never drove the v6. what do y'all think?

What is the hp and tq difference? The I6 is pretty hard to beat, but isn't the V6 like 75 more hp?

Tural

i don't know what the real numbers are on v6. i'm guessing around 230 240hp. but i beat one with a v6 in my cherokee classic. he couldn't pass me up until 75-80. it was a 4-door

Was the V6 in the Jeep even a 4.0L I thought it was less????

iv never seen a v6 cherokee personally, i go to the junk yard almost every weeknd and all i see are 4 bangers and i6. never made alot of v6 engines eh? my guess that the i6 was more torquey and praformed better off road than the v6?. i love my i6 iv towed a 32-34 foot RV up hill with it. no one thought it could do it. and raced a v8 f-150 we was neck on neck the hole way and i still had 5th to shift into. just ran out of road. thats my experience id take a i6 over any V6 any day. and i plan on rebuilding my i6 into a stoker one day :P

Looked it up. Seems to be correct.....

The 3.7 is from the liberty's. Couldn't find anything about a 4.0 V6 in a Cherokee

XJ never came from the factory with a 4.0 V6.

from like 85-89 or something there was a 2.8L V6.

dude i can't find a single realistic thread on how to completely rebuild into a 4.7 stroker. i heard you have to modify your stock sensors to get it to work right. i would love one, but i don't wanna break the bank. i got the jeep for free and i love the i6. it's a killer. i heard they can run 200-300k miles. some even more.

the 3.7 v6 has overall more power but i heard that they are just complete pieces of crap and arent reliable as the i6

well, also happen to own an 04 dakota 3.7 and i promise you, it's a different beast. i trust my stock dakota off road more than i trust my 4.0 jeep. me and my wife set them head to head, and the jeep took the upper hand on the first 300-400 feet, but then i blew by it. around 45-50 it started catching up but couldn't cover it. my dakota is 5-speed.

Tural

has anyone ever done a 4.7 stroker? if so, is it worth it overall? i mean i don't wanna have a straight out drag car horsepower that get 2 miles a gallon.
