Since my last post I have been considering repowering my lemon bus a 64 silver eagle with a used engine. It has a 8v71n currently what what engine would produce more power then the 8v71 and fit. I figure that if the weight is the same and you produce more power the milage should go up slightly. nay thoughts? |

The only engine that will "fit" right in without modifications is another 8V71. A turbo engine will require modifing the turbo mount and exhaust system so it will fit under the floor. A 6V92TA can give you 350HP vrs. your old engine that was somewhere between 277 and 304 HP. The 92 will give you more power and better fuel economy for the power. I get 7-7.5 mpg with my 350HP 6V92.

If u consider the bus a Lemon, why would you consider repowering it? If u are going to go the time and expense of a re-power, I would seriously consider something along the lines of 4 stroke power rather than a DD 2 stroke. Nothing wrong w/the 6v92, but there are better options to consider if you're set on a complete repower. Is the trans. under consideration also? |

i did not say the bus was a lemon i said that my lemon bus (i'm just mad at it, it will come around some time) I would like to have a better driving experiance when tooling along and those hills uggg! since I am having other problem i am looking at all of my options and benifits. I think add horses is a good thing for the ecomomy of it. thanks for those who add something here. |

James makes a good point. A repower should consider the whole package, engine trans and rear differential ratio. Do lots of research! |

John: Sorry if I mis-interpreted what u were saying. But, to take things one step further than what I previously said, I tend to agree w/Brian. In many cases it could well be cheaper to go out and buy something more to your liking that is in better mechanical condition and equipped like you want it. If u are somewhat dis-satisfied w/the bus before u even get started w/ the conversion, prospects don't bode well. In today's mkt., many are "eating" a lot of time, effort, and money just to sell. I have yet to see a re-power job done that didn't end up as a major project that gobbles up far more time and money than imagined at the beginning, not to mention all the frustration and headaches that go along with things not going as planned and considerations that were not considered until the "point of no return" was reached. |

RE-POWER...Go big...The real Headaches of doing it will pass And you will be happy!...You will be seeing a repower job that did end up as a Major Progect that will goble up FAR more time and Money then Imagined with true Frustration, thing not going right. There is the "NO POINT OF RETURN"...That is when you start! One good thing is at the end of this project is...YOU will be saying, Its done and I am a "Bus Nut", and I did it "MY Way"

I would like to know what happens to the rear end on a big repower? Chance of it busting goes up? Im sure when the bus was built there was a spec on the HP the rear end could handle. Has any one checked to see what you can put to it with out it going bad 10 times faster then with the stock motor?
Im thinking you go from a 295 hp motor to one with close to 450 or 500hp if you go big ,one day you will hear a snap when some thing busts.
Most bus rear ends was built and spec for buses and not a truck rear end so I would think it would be spec. for the motor and HP the bus come with. Just like car you dont get a mustang rear end in your pinto. Even the same car V6 or V8 with the V8 you got a bigger rear end. I dont see why buses would not do the same.
One thing I know that is fact more power the more heat and strain on the rear end and faster tire ware.
Just my thought.

disagee (respectivly)...if you plan on burnouts...rear-end will not last....putting ONLY the power you need to the rear-end...it will last a lifetime |

My bus does burn outs now.
Then why go for the extra power if you can not put your foot to the floor and not worry about busting it?
For me a extra 5 or 10 min on a hill is cheeper then a repower just so I can try to keep up with the million $$$ rigs. And the 10 MPG is ok with me so far.
Its easer to make a light weight conversion then a repower. If any one been over Hwy 22 east from hwy 5 in Oregon there is a few good long hard pulls.
With my 4905 total weight with my pickup in tow 27700 LBS at the scales at Klamath Falls pulled the pass in 3rd and 4th and some spots you could not go any faster in the turns then 45mph any way.
Now my bus is not converted yet but is full of plywood and tools 3 extra tires and wheels full size air compressor and about 1500# of parts and crap. Bus: Front 8650lb Rear 14550lb pick up truck 4500lb.
I would like to know power to weight how would that compare to a heavy conversion with a big motor repower?
So my thinking with building a bay car 1200lb and if the converson dont go over 2000lb I should be around the same weight as it is now give or take a 1000lb or so. So I can see with a mci or eagle starting out 10000 lb more then the same size GMC where you could have a problem power to weight so you take 15 min more up the hills .

Error. I got the road wrong if any one cares.
It was hwy 58 starts at Interstate 5 at 419 feet and goes up to over 5100 feet .
Oregon's Highway 58 traverses the Cascade mountain range, beginning at Interstate 5, just south of Eugene and ending eastward at Highway 97, just north of the Central Oregon town of Chemult. The Willamette Highway travels through the Willamette National Forest, The Deschutes National Forest and skirts just north of the Umpqua National Forest.
ya I know who cares.
