wouldnt this be the best engine for a swap? being its only a 4 cylinder, its plenty short, available in alot of inner city buses, and rated at 250-320hp, it would be a prime candidate for a swap, more room left for a overdrive auto trans also.....anyone else pondering this idea ?

by the way the 320hp version has 1150ft lbs of torque !!!

Very interesting setup. I believe the issue will be the 2100 rpm governed speed and the 6.72 to 1 axle ratios. I am aware that 4 something axle ratio's are available from O Engineering, albeit, some claim that they are rather weak and best suited for Jeeps and such. Braking is another issue with that kind of power and speed but I saw another vendor who had outboard disc brakes to mount to these axles. I'm sure anyone who had the money to convert to a dual circuit brake system compatible with disc brakes, replace the gears in the axles to one's rated to this duty, and do the swap would have a pretty neat Deuce. I'm not that individual so I'll stick with my 305tq/134hp set up as delivered to Uncle Sam and drool at the person that does put together a set-up with that 4cyl Detroit.

with the stock axle ratio, an overdrive automatic like an md3060, you could cruise that motor at 2100, save fuel , and have plenty of torque. the motors are on e-gay for 2-3k.

the shortness of the motor makes a overdrive allison or a good 10-13 speed tranny a great possibility, these bigger trannys wont fit behind a 6bt or any cat motor

I too have thought about the 4-53 in the deuce, Just never lucky enough to find one. I recently found a 3-53 im gonna grab, for what I dont now. Keep in mind most busses rack 1,000,000 miles on them before de-comission.

There is a guy here who has at least one, maybe 2-3 running 4-53's. They were pulled from 10k forlifts that ran, but they were parted because monster truck builders pay big $$ for the axles.

i've been pondering a 6v-92 two stroke, They just sound sooooo mean. By pondering I havent made any attempts to see if it is possible, but a detroit under the hood seems like it could be a lot of fun.
 
How about a 6V53? I've got one with an Allison 6 speed behind it. Never even considered it.

Big problem with the detroits is the **** accesory drive unit runs off the back. If you could get around this I think it would be much easier.

Dont worry the deuce front axle can take the extra weight :D

The torque increase will take care of the extra weight, might wanna go full hudro steering to make it more streetable.


what does the multifuel weigh ? Id bet it is over 1500.

Hmmmm, seems there is some cross-confusion between the 2-cycle 53-series (3-53, 4-53, 6V53, 8V53) and the newer 4-cycle Series 50. The Series 50 is derived from the larger Series 60 4-stroke, but with 2 fewer cylinders. The Series 50 4-stroke usually features EGR and a few electronic controls on older motors. Some of the newer 2-stroke Detroits came with electronic controls for emissions (DDEC), but typically the appeal of the older 2-stroke "Screamin Jimmies" is that fact that they are straight mechanical and fairly easy to work on.

I have a 4-53 with turbocharger in my 1986 GMC 3/4-ton I'm getting ready to swap over to a 1994 C-6500 chassis, once it's shortened to pickup length (4-wheel disc brakes, 19.5" wheels) and I find a fiberglass tilt hood to replace the pickup front clip with. I just spent all last weekend chasing fuel supply problems, and used a universal 12V fuel pump for fuel system priming. I'm just glad I didn't have to drop the fuel pump to re-clock it after becoming air-locked.

The Deuce engine compartment seems suited for an inline diesel design, much more than a V-configuration. I have a line on a 4-71T and a 6V92T Silver engine, but the 4-71 seems like a better fit. A 6-71T would be ideal, but I can't find one in my price range (CHEAP).
