Like I said I haven't really looked at the 2.5L but when I get back from this tour in Korea I may hit up a salvage yard and pick up a motor and build it, it would be cool to do, just because it seems no one has done it, or done it well.
Yea, without trying things I guess we would never get anywhere. Let us know if you do decide to try it. Must include pics tho!

Only problem with my 4.0 for me is passing power and MPG. Once I get up to 55-70 I'm great on the highway but I only have 31 A/T's and no lift so I'm sure that helps. It has plenty of town and off road power tho!

That the Jeep's 2.5L and the Mitsubishi engines both have four cylinders is where the similarities end.
I need to find a site that has the break down on that motor...like I said I have never payed or looked at that motor.

Now I must really go find one and play with it....the challenge has been layed out (well at least that's how I will justify another motor build).

Looks like my winter is now planned out!

Agree'd, I can pick up a motor in the salvage yard for around $350 and I have tons of spare turbo parts and stuff in my garage, as soon as I return to the states I will start the project and keep it posted. I love challenges.

I dont have a 4 cyl and never saw anything about it
but I know you can stroke the 4.0
is there a stoker option for the 2.5

You can pretty much stroke any motor, depends on the thickness of the walls...money is ones only limit when building motors.

I bought the factory service manual ($150) when I rebuilt the trans in my jeep a few years ago. Same one the dealer tech's use. It has any specs you could possibly want it in.

bore x stroke = 98.4mm x 81mm
compression ratio = 9.2:1
140 ft/lbs @ 3500 rpm

I too have thought about trying to mount a turbo up on my 2.5 I have a 92 eclipse project car (my 3rd dsm) so I have tons of spare turbo parts around. Just need to figure out a way to tune it.

Old school
211hp naturally aspirated.


296hp turbo.


Stock air cooled VW motor runs around 50 to 60 horsepower, if they can get performance increases like this out of an engine designed in, and pretty much unchanged since the 30's I bet you could get some pretty impressive power out of the 4 banger Jeep motor with it's much stronger design.

Yep, I know what i need to find now...I was a DSM guy too, can't even begin to count the amount of 14B's I have pulled and swapped.
A simple fuel/air tuner like a SuperAFC would would work, hell you could even use the stock wastegate off of a DSM or Dodge shadow...even a 13 off a stealth would be a small enough turbo you wouldn't have to play with the compression.
The more and more I think about it the better the idea sounds.

I have another post about my starting/running problem. If I can ever get it taken care of, I might just go for it too. I actualy have an SAFC-II, and by the time Im ready to attempt this I won't need it for the car anymore.... Will it work on OBD2? Think any fuel system mods would be needed? pump? injectors? afpr?

For safety I would go with a bigger pump, don't think you would max out the injectors on a small setup like a 13B. You could always go standalone; say a megasquirt setup.

I can't wait to get home and start this project.

I've got the 4cyl in mine. I added the intake, headers and bigger TB with a spacer when I first got my rig. None of it does a damn thing as much as people tell you it does.

If you want to get more power out of your little beep beep sell it and get something with the power train your lookin for or.... Swap in something that you want. I'm lookin towards the latter choice cause I've invested in alot already and I love my jeep...

Well home is where the heart is...and right now all 3 of my hearts are living in Bossier City LA, and that's where I plan to be; come 4 more months.

I still have to buy my Jeep when I get back; I had a Jeep a long time ago and have always wanted another one, but fast cars and bikes have put that to the side...now I want to get back into them. I'm still keeping the fast bikes, just now I want something I can play around with on the trails.

I have to get my MIG welder back from my father so I can throw some pipes together for the turbo, but if plans go the way I want, I should look at starting my project around Jan this year and finishing by early summer...that is if they don't send me to another damn foreign country again.

It seems to me that I have heard of putting the injectors out of a newer Mustang in the 2.5. It it supposed to help with the horsepower some. I have also thought about turbo'ing a 2.5. I had a Cougar that had a 4 banger that had turbo, it was not gutless. Pulled the large body car just fine.

It doesn't for one reason, the PCM (engine computer) prevents them from squirting more fuel in there than the OE injectors do. It's all about the PCM requiring a precise air-fuel mixture as measured by the 02 sensors and the PCM controls the fuel injector pulse width duration to achieve the proper air/fuel ratio. If the Ford injectors can inject more fuel, the PCM will just cut the time they are held open so as to not inject more fuel than required to achieve the proper air fuel mixture. The only thing that you could do to cause them to inject more fuel would be to force more air into the engine and the only way you can do that is with either a turbocharger or supercharger. Only with forced induction would the PCM then cause the injectors to throw more fuel at things.

With today's modern computer controlled engines, it's very hard to throw parts on them that will produce more power. The PCM will just change how that particular component runs until the PCM is happy and the engine is running as it was before.

Exactly. I ran across a problem just like this while building my bronco. I built a 351W from a 95 lightning added a cam and some other parts and in order to even make it run right, I had to rewire the entire engine wiring harness to run off a mustang ECM. Although I wanted to do that mod anyways because it's supposed to increase MPG, HP, and throttle response, I had to just to make it driveable.

Correct, throwing larger injectors on a modern motor alone will not help and in most cases would hurt...but an easy cure for that is a piggyback to the PCM that "fools" the PCM into doing what you want it to do, there are tons of universal fuel management systems out there. Giving your stock motor more fuel is not going to do anything.

When you start adding forced induction into your equation is where you need more fuel, running rich will hinder performance, running lean will cause "things" to go boom. I have always went with a little rich on a "seat of the pants" tune....there is a fine line you have to find when tuning to get the most bang for the buck.

You just can't slap on a turbo and be fine, you have to upgrade the supporting components in order for things to work well, fuel, air, exhaust at a minimum...to much power over stock will start to stress drivetrain and internals of the motor.

For a mild setup with the 2.5 compression, I would think that 7-8psi be safe on that motor. I guess we will find out.

I would seriously doubt that Anyone would want a Turbo for offroading! It is desined for High RPM's if I'm not mistaken. However a Super charger is another story!

4.0 is the only way to go the 4 cyl dont last and are very underpowered.

Prbabley a the cheapest and easiest way to get power and mpg is to get like a jet mod(module) and a borla exhaust system or whatever kind you want but it will give it maybe 12lb of torque and maybe 15 horsepower but you will definatley need it if you were to get a jet mod or a chip. The stock exhaust will pretty much just cancel out what the jet mod would give.

well if you think you can get anywere close to the HP your saying by building and turboing a 2.5 Dale i got a jeep you can practice on. id love to do a swap but i don't have money to do the hole deal yet cuz i'm sure the trans and axles i have wouldn't hold up to something like that yet. there still stock. so if you make that engine what your thinking im sure i can work out getting a trans that can hold up

It's not want you want to hear but the best mod you can make to your 4 banger is to put the stock size tires back on it. My 99 SE came (used) with 265 75 15's which if I remember correctly is a 30.5 inch tire. Without a re gear this little engine doesn't really like bigger then stock tires. If you figure the price of a re gear you can sell it and get a 6 cyl. I went down to a 235 75 and the drive improved and the mileage improved also. It just didn't run at the right RPM to get max performance with bigger tires. I loved the looks of the bigger tires on my jeep but in the end I am glad I went back down. I didn't want to make a bunch of mods to mine so I sacrificed the looks for the driveability. I think the jeep engineers were spot on with the set up for the 4 cyl because there doesn't seem to be much you can do to make huge improvements.

OKay siple stuff here on power mods.: First intakes. If you want to KNOW what and intake mod will do hook up a manifold pressure gage to the intake manifold (old aircraft units are cheap if they need a rebuild). measure the before and after readings at WOT. IF the reading differances are small the power differance will be small. OH before you start IF you read 29.92 inches of pressure at say 25 degrees C at sea level you are NOT going to improve anything since this is as good as it gets. IF you see a WOT manifold pressure corrcet or 28"or lower you may have some ability to get a few percent. Tat is it.

Note a guy dynoed a 4.0L stock andgot about 148 hp to the rear wheels on a 190 hp rated engine, so you can expect about a 20% drop from the 4 also to about 100 HP rw +/- a few. You can guestimate the HP required to rool down the road at 60 by your fule milage. Most folks report MPG of about 18 on the 4s cruising at 60 is. So you are burning 3.3 gallons per hr or 20 pounds per hour. A fule injected engine running LOP which these do at part throttle near torque peak will run a specifi fuel consumption of about .55 to .65 pounds per hp per hour. so you figure 30 to 38 hp to cruise that would push top speed to about 90 mph or so.
IF you could get another 20 hp RW (which is hard to get) you would only gain 3 to 5 MPH top end (cube rule) and maybe 5 % accelleration 0 to 60.

If you do not like th power for hills on the fwy then get a 6. or shift. who cares.

Modern engines do not leave much for power improvements. the 4.0 and 2.5 were builts as off road truck engines. to be durable and produce adequate reliable power. These thing run a long dang time.

WHen I screwed with Harleys and buddys wanted to go fast my comment to them was..you want a fast v twin? buy a ducati. All the great bits of an HD are smooth relaible easy to ride power, all gone when you build the engine.

I guess from an engine building stand point it would be fun to see someone lower the compression ratio on that motor, throw some fuel in it and boost it, not good for hills and climbing, but a smaller turbo would help reduce the lag and make for better highway and driving speeds.

Anyone tried this?
I beleive the 2.5l has about a 9.0:1 or 9.1:1 compression, im not sure but the piston rings are pretty tough but the gaskits and seals on the 4cyl are shit.
But you would need some BA seals. Probabley about 3-4 pounds of boost would be sufficient. After an aftermarket fuel pump and maybe slightly bigger injectors and some e3 spark plugs. THatd be about 65 - 70 horspower, but id reccomend a high flow exhaust and aftermarket aif filter or intake manifold.

Electric fan conversion will do you some justice for only a little bit of coin,they run only around 200.00 for the kit and they will give you better mileage and give you more pep in your step.Me and a few others on here did the electric fans and the improvements are real deal.I run the ffd system and a few others run the flexlight systems.

I dont know a sight specifically for it.
But i know a thing or two about the little 4 banger.
120HP @5250RPMs, 139ft-lbs of torque @3250RPMs
Redline-5,500
150 Cubic Inches
MPFI-multiport fuel injection
9.1:1 to 9.2:1 compression ratio depending on year.
From 1992-1995 it pushed 130HP and 149ft-LBS of torque with a 9.2:1 compression ratio.
Bore x Stroke = 3.875 in (98.4 mm) x 3.1875 in (80.96 mm)

The 2.5L engine produces about 120 HP design SAE net at the flywheel. This is at Sea level where the manifold pressure at wide open throttle is 14.7 psi or 29.92 inches of hg. 3 to 4 psi booots will require a cetain amount of exhaust back pressure to drive the turbo this from equations not to be quoted here is on the order of 10 hp to 15 hp if thing work well. This is NOT free is comes from reducing the exhaust efficieny but only by about half the amoutnstated above. ALso one must take into account that the maximum hp increase (if the porting and such can support the increased flow linearly, which without porting it cannot) will be a ratio of the new max manifold pressure devided by the std manifold pressure. In this case 4psi +14.7 all divided by 14.7 psi.Which is about 18.7 / 14.7 or 26.7% or maximum power improvement of 32 hp. However that is assuming the porting can support this and that the drag fromt the turbo not significant. realistically think more like 22 to 25 hp. Remeber the combustion chamber is NOT desgned for the increased pressure so a lower ing oft he CR would be prudent to prevent detonation. so you may be looking at more like a 20 hp increase or 140 hp total.

Itr would cost less to seel the 4 cly jeep and buy a 6

I'll be honest. A turbo is really the most financially wise option when it comes to gaining horsepower. I'm not sure how savvy you are in the machine shop, but if you get a turbo off of a 2.3L Ford Probe and the waste gate, you can use it. Matching your turbo to a similar sized engine is important. The only thing you have to do, which if you look at pictures on 505 Performance, its exactly what they did. Route your exhaust underneath the oil pan from the stock manifold. Run it into your turbo, then run the exhaust out of the turbo, right back into your stock exhaust. Run an oil line from your pressure gauge and a return line right into the oil pan. There are a couple things i'm unsure of in my turbo. I'm not sure if I need to change my injectors and alter my computer. I won't know that until that time comes. All in all, I'll have WAY under $400 in a turbo and that includes purchasing the turbo (junk yard).
