I was just wondering if anyone knew who or what company made the 2.5L Engine. I know at one point and time that dodge did use mitsubishi engines in some of their cars but was curious as to if my little 4 cylinder might be one as well. Any information or comment welcome.

 

It should be the same motor that is put in jeep wranglers. Currently, Chrysler, Mitsubishi, and Hyundai build motors in the same plant, but as far as Ive seen in the salvage yard, thay are Chrysler/Jeep made.

 

well hmmm, I was planning on over hauling my little 2.5L engine but wasn't for sure who made it. If it was a mitsubishi I was thinking of maybe getting performance parts for it and upgrading it. Unfortunately I don't know much on how to beef up a small inline 4 cylinder. I know there are tons of thing that can be done to most small engines. I just haven't the slightest idea as to where to look for them or who might have done it. I have friend that can take his Nissan and add enough to it that it will run with enough power as a V6. My poor little truck hasn't got much power, i'd just like to see my truck have some more ponys and make the other guys look twice.

 

V-8 swap is really the best overall way to wake up a 4 banger. The 318/360 os a timing chain driven motor, vs. the timing belt of the 2.5L.

 

YESSSSS SIR

 

i was actually at one point looking about getting a v6 motor for it. Really don't want the gas hog v8's.

 

Just becuase the V6 is smaller does not mean it will get better MPG. If you are going be working it or trying to make the other guy look twice,the MPG will drop off fast. The v8 will not have to work as hard to pull your truck. My 95 5.2 with a M1 intake and a CARB , gets 20 MPG .I know that is not great but , my friends 3.9 gets the same MPG. But then I like to baby my truck. I am sure the 5SP and rearend died of natural causes.

 

Well I just got offered today a 318 engine that needs to be rebuilt. I actually (I know what I said previously about v8's.) am considering it. The guy wants to sell it to me for $100. My question is, on the suspension of my truck which right now is running a 2.5L, what would have to be changed to swap it out with a 318. I've never done an engine swap before, and a 318 would make my truck sound and runnin a lot beefier. lol

 

You will need to get the v8 springs. The tranny also will not work. You will blow it out in no time. It is not rated to handle the increased torque of a V8. There is a lot more work and parts needed to swap from a 4 banger to a V8. Need a wiring harness, PCM, tranny, flexplate if not included with the engine, starter, various sensors - IAT, CPS, T-stat, etc. Probably a new radiator, clutch fan for the V8, airhat, fuel rails and injectors, hoses, possibly new accessories as well. I don't know if the stock 4-cyl alt, p/s pump, A/C will bolt to a V8 or a V6 for that matter.

 

Flexplate note- Depending on the year, 96 and up engines run a flexplate where all the torque convertor bolts are at 90 degrees to eachother, (evenly spaced) 95 back flexplates have one bolt that is about 1-2 degrees off from peing perfectly in line. If you use a late model motor and flexplate, you can use an earlier model trans with a late model torque converter IF you swap the front pum gears in the trans to late model gears. The V6 trans (500) will hold up if a good shop built it well with close tolerances and used good components, the heavier trans (518) is optimal.
Like it was said before, all your components will be different, and wiring is more invasive than a 6 to 8 swap. GOOD LUCK Any questions, feel free to ask.
