Title: The new 4 banger......specs too....
Post by: 4low on January 13, 2006, 12:03:55 PM: Anyone driven the new 4 popper and been able to compare it to the old 2.5? What's your opinion?

Also, does anyone have the specs on the engine? Like Bore/stroke, intake and exhaust valve timing? Lift and duration? and comp. ratio? (also, does anyone know how many valves per cyl it is?) All I know is it's something like 150 HP and DOHC.......any more tech info and opinions/experiences would be awesome!!! Thanks!

If you want 4cyl go with the 2.4. way peppy'er and seems to be able to hold highway speed better (I swapped my 31's from my 2.5 onto the 2.4 for the trip so it was a great comparison).

they should put the 230 hp version of the 2.4in the tj ,,

turbo jeeps would be cool

The highway is where you'll notice the difference.... but it's way better than the old 2.5L. This engine and the new 6 speed tranny works great togeather. It's not that hard to keep up to 110, unless you got a good headwind, or if you are towing........I'd place the 2.4L in the middle of a 4L and 2.5L as far as power goes.... if not closer to the feel of a 4L....

I'm also told that intake upgrades will provide more of a benifit to a 2.4L than a 4L, but I haven't really looked into that yet..... Plus I believe it's the same block as used in alot of Chrysler cars, so it wouldn't be too much work to hook up a turbo :P

Dragonmaster, I was thinking of getting 31" for my Jeep.... how much of a difference is that in the 2.4L going from stock tires?

Hardly noticeable IMO.

Post by: 4low on February 05, 2006, 10:59:45 PM: that;s a cool website!
thanks for the info, but no one has the valve lift/duration and timing? it was in the factory manual for my 2,5, was hoping someone could pull it up for the 2.4 in the specification section......

thanks!
