C240 versus C223 engine question

Post by S-10 luv'r »

:?: I noticed that there have been C240 engines on e-bay and in one pic it looked like the bolt pattern was the same as the C223 engine and most of the other component placement looked the same also. So i was wanting to know if anyone has ever used one of these engines in place of the C223? after all the C240 is only .2L larger in displacement. :!: I wanted to know if it is possible to use this engine if the C223 ever becomes impossible to find. and what are the physical size differences to the C223? anyone help here? Or is there any other engine that can take the place of the C223 directly? :|

THOSE ENG,S DONT USUALLY WORK TOO GOOD FOR A STREET VEH, THEY ARE BUILT TO RUN AT A STEADY SPEED AND ARE WAY LOWER ON POWER THAN THE C223, THEIR UPPER REV LIMIT IS MUCH LOWER THAN THE C223 ALL SO, THEY HAVE A GEAR DRIVE FRT PUMP SETUP, AND ALL SO MOST ALL OF THEM HAD DRY SLEEVES , JERRY

Hi, in my country, C240 is direct bolt replacement for C223. I ever done that on my Trooper.
But like JLemmond said, it's not good for street use if you don't change the gear drive (transmission or Final Gear). Mine is blow up within 6 months use on highway. Their upper limit revs is on 3.000rpms vs 4300rpms on C223.

In here, C240 use on Jeep CJ-7 with much higher Final Gear than C223 Isuzu.

Some info about C240 : http://www.dieselenginemotor.com/isuzu/ ... page2.html

It's not the same C240--it's the industrial version.

You misread Jerry's comment.

He's saying that the Injection Pump is gear-driven on our C240 engines. Again, that's an industrial engine.

Yup, you're right Jack. Industrial engine is different than auto purpose engine, although it's the same engine type. Just want to add some information if you get the C240 auto-purpose engine.
My C240 is formerly used by a forklift, then my friend put it on his Trooper before give it to me.

Yes it's gear drive injection pump, I miss read it. What I mean is overall gear ratio.

Sorry :?

I don't know how to work the rpm's problem out but gear drive timing is a real upgrade in other motors. Probably an injection pump upgrade could turn the motor into real performer if the internals are up to it.

Would it be possible to swap the crank out of the c240 into the c223? Or would the gear drive design be an issue?

the 2,800rpm high idle of the off road engine, would be a killer for road use.

here in the philippines, a lot of Isuzu C-240 engines were used to power jeeps and elf trucks. but they had a 5-speed transmission and this helped to make it more driveable on the highway

What would be the sort of "replacement" be since they don't manufacture C223s anymore (right?) if someone wanted a brand spankin' new engine? I've heard of these 4bj1 (Or something) but are they really the same size and rated for the same efficiency and everything?

I wonder if a c240 crank could be used in the c223? The 223 has a stroke of 92mm, where the 240 is 102mm. If we could use this crank to "stroke" our motors, displacement would increase to 2.48L! The torque increase would be awesome.

Im curious about the bore? Could these be oversize pistons for the c223? Wrist pin size?

I went and bought a c240 because of this thread. The 240 has a bore: stroke of 86mm:102mm. The c223 is 88:92. Im currently building a c223 with 240 parts in the thread, a trooper revived.

Hi
I drove an 18 wheeler all over the US and never got over 2100 RPM.The C223 will last indefinately if kept below 3000 RPM.It takes heavy metal to make 400 psi and it changes direction at each end of the stroke,since E=MC2 a body doesn't like to change direction at that frequency.
