natax I think I just shit myself hearing about this 2.5L putting out that much power. I don't think it is a 2.5L at all, it can't be. If so, you should be wheeling in it. No need to have that much power and not use it off road. Or you could always sell it and make one hell of a profit.

CharTay And there's no forced induction of any kind? Idk about this

Yeah, but not with 250lb-ft. More like 130!

Xpress There's just no way in hell that engine is making 200hp, if it is then it's not even a 2.5L engine that halfway resembles the stock engine. Could be a Honda Type-R engine, they can reach 200hp without much fuss.

American 2.5L engines are big, bulky, inefficient, and basically impossible to make such massive HP figures over stock without an idiotic amount of cash wasted, they're not desirable for high performance engines. None of us are believing you until we see:

-Video proof of said engine putting 204hp to the rear wheels.
-Video evidence of cylinder compression
-Pictures of the engine fully disassembled.

P0234 Even a 16 valve NA 2.5 is going to have trouble hitting 200hp. Sorry, but I wouldn't even believe a dyno printout at this point, it'd take a youtube at a known dyno facility at this point.

If in fact it does make that much power, you need to take it apart, find out what he did, and start selling kits, you're going to be rich quick.

+1. For a 2.4 to put out 200+ at the tire is going to have to be seriously built! Depending on the type of dyno used, there are corrections that can be applied to make it display any hp you want. Accurate dyno results are a combo of the dyno operators integrity, and the dyno itself.

Yeah lets hope not. Your probably right.

Maybe he is too proud to reveal his magic.

fuel blockage

If all else fails, you might want to check the rubber fuel connections to the metal lines. Especially on the input side. Sometimes a flap of the inner liner can get sliced and intermittently block the inlet, say of the filter. Something to check when all else fails.

Ibuildembig x2 I just played around on my dyno program with one and even at 12:1 with a ported head, roller cam, etc etc it only did 178hp and 155tq
04-26-2012 10:20 AM
P0234 Yeah, aside from a supercharger/turbo/nitrous, there is no way the 2.5 is going to put out that sort of power.

1994 2.5L YJ losing power

Hello all i have owned this jeep for about three years and recently had to replace all the rubber fuel lines and fuel filter. After doing this i have noticed very small random losses of power (like its running out of gas) it doesnt seem to favor any one condition. It does it hot, cold an as well as at any angle. I do not take it offroad. Just trying to find out what could be causing this. Thanks for any help.
