I don't know if this goes half in one section and half in another but I've been kicking around the idea of building a car for awhile now, in between trying to save money to buy a house i think i can build one in time for next season in between working 2400 hours a year ;D. I started off with a simple plan was gonna use a 1999 600 ninja with an rpm or jeffco, then kicked around making a solid axle rear, the list goes on and on. I want to put a Honda b16 in something along the size of a long travel rhino, with 930s ( i think) and hopefully mid engine. what transaxle should or could it be hooked up to without spending 6k plus? My main concern is reliablity, that's why i think i'm going with the honda motor, those cars run forever. maybe i should call az trans? but i value your guys's opinions, thanks guys.

Don't confuse Honda cars with Honda bikes. Different design team and end results ;)
In my opinion MC engine toughness goes:
Suzuki toughest
Kawasaki almost as tough as Suzuki
Yamaha & Honda not as tough (or as well designed) but still perfectly useable

Icky,
Sounds like you are thinking Bus Box. Lots of Honda cars out there. Some guys run them in the buggies. Adapter plates, etc might be tough to come by, but not too bad.
One option, as it sounds as though cost is a concenr, is to use a vw on the front end - hear me out here folks. No rad, or ecu costs etc, and oddles of parts. Now as far as reliable - do you have to maintain them? yep. Get you home at the end of the day? Yep.
Could be a slick car and the transition to honda / water cooled, if planed from the get go, would be fairly easy......
-
is that what you're running, a bus box? you have the sub motor right? I'd rather stay with the honda cause i friends that can get me a real good deal on one complete, they do all that import stuff. I don't see me needing to have that thing push over 200 hp, so i don't need a mendi or anything like that i don't think.
-
yep. Bus is good to about 300 is what I hear. Even if you get to 250+ you would still be good. Check with bill of aztrans - he can help and is a heck of a nice guy.
-
didn't you just break yours or get it fixed? how'd you do that? or did i read that somewhere else? What kind of car do you have? Sorry for all the questions
-
I did break it, and it is fixed.
I did it by failing to honor rule number 1 - DON'T USE REVERSE IN THE FFN SAND.
So, I got to pay the cost to learn that lesson. Was the box in great shape to begin with - nope - not likly, the way it was explained to me is the tranmission was good, the differential was worn / not so good - i put it over the top.......
None of them cant be broken. Albins, Fortin, Mendeola, they all break. When is the only answer to consider.
But, in my mind the bus box, for my application, is a good choice for me. Would likely be a good choice for lots of cars using auto power below 300 hp and a budget constraint. Would a Mendeola hold up better - sure. But at that price, I am out of the game. Having said that, a Mendi 2D is - I have been told - about 2k more than a "built bus." Course it is a lot more than a "stock built" bus. So, maybe it is pay it now, or pay it later?
Or, in my case, pay it once, pull my head out and call it good? Friend of mine got 7 years on his bus box. Assuming I keep the cr, I would expect I will NOW do the same.
Note to self - repeeat again and again on the long drive to the dunes:
"Dont use effn reverse in the sand"
repeat again:
"Dont use effn reverse in the sand"
repeat again:
"Dont use effn reverse in the sand"
repeat again:
"Dont use effn reverse in the sand"
repeat again:
"Dont use effn reverse in the sand"

That helps, I feel better now... It's a shame I get to sleep between now and them.
Car = Sand Limo Squirt. Ask away, that is the purpose of the forum....

I like the sand squirt, a friend of mine has one with the gsxr1000 in it. Here's my novice question for the hour, why shouldn't you use reverse in the sand, or was it the way you were using it? Thank you for the help
-
On of the smart guys will tell us "why you should not" my answer - it makes a loud "pop" when you do.
My inclination is they are designed to go forward not backward, so, there is the why for me. Again, one of the smart guys can help with the "real" reason.

The reverse gear is just very small and weak. The Mendi 2D I believe uses the same gear.... so it is not an upgrade in that department. It addresses the forward weakness of the bus..... The ring gear. Mendi 2D uses a much larger ring and pinion, but the 1-4 gearset and reverse are the same as in a "built" bus.
-
I guess i'll have to wait for one of the smart guys, maybe they can explain why they have reverse in them if we shouldn't use them. ??? nevermind someone just answered as i was thinking of something to say. Sooooooooooo it's usable just be nice to it? I don't want to drive in reverse everywhere ;D i was just wondering in case i needed it.
-

If "just backing out of this hole" turns into, "I will just pop the clutch at wide open to get out", you will definately hear Yummi's POP. :P :P :P ;D
-
Mine was "backing out of hole" no popping of clutch required. Course I was also backing "up" instead of "down."
-
Where did you get your box from orginally? Do you think it's more solid now that AZ fixed it.
-
All engineer and yummi have posted is correct.The reverse is and always will be the weak point of the bus trans and the higher dollar mendi's.Reverse is just too small no matter what you make it from. On the other hand be nice to it and it will serve the purpose pretty well.
-
Came with the car. Yes, yes, I know it's a builder board - for me its a fixer board.
Do you think it's more solid now that AZ fixed it.
YES! It had some good stuff before, but some of it was a little Jethro. After Bill took the time to show what / how / etc I am 100% certain it is in much better shape. You can learn more here. Bill will get you the hookup that would be dollars well spent for your application.

Yummi, when it popped, were the tires wheel hopping....
-
Nope.
-
Hmmm, Sand and wheel hop will break a tank, Generally I find wheel hop to be very easy in reverse.... ;D
-
you suppose that has something to do with the paddle tires going backward at that point?
-
No none at all, it is just the weight distribution of the car, I have wheel hopped a 40ft straight truck at least 250 times, probbaly more, loaded they go thru the sand no problem, as soon as they are unloaded and the weight shift they just wheel hop like a bitch, the paddles will make it worse as there is so much sidewall and such low air pressure, i have always backed up quick...

The reverse gear is just very small and weak. The Mendi 2D I believe uses the same gear.... so it is not an upgrade in that department. It addresses the forward weakness of the bus..... The ring gear. Mendi 2D uses a much larger ring and pinion, but the 1-4 gearset and reverse are the same as in a "built" bus.
[/color] The MD4-E uses bus gears. The 2-D uses much larger gears than a bus. The reverse however is a stock VW part. When VW designed the gearbox it was supposed to use a 1200cc, 36hp motor with 25 inch tall tires about 5 inches wide to back a Bug up on pavement.For that purpose it is adequate. VW never considered paddle tires,big motors,or sand. Mendeola looked at what broke the most in the bus(ring&pinion,case,and differential)and beefed it up.When ever you strengthen a weak point you just shift it to the next weakest point. Second became the weak point which gave birth to his second design(2-D). Then it was the input shaft so we got the G-50. Everbody new reverse is weak DONT use it. But enough people complained so now we have the S-4. If you have $13000.00 and enough room in your car for a 2 hundred pound transaxle great. If not, don,t use reverse!
-
200 lbs? :o what's the bus trans weight? Couldn't you just throw a stronger reverse gear in there, like i said earlier i'm not planning on drving in reverse everywhere, but from what i understand it shouldn't be used at all unless i want to visit you all the time ;D btw thank you for taking the time to reply to this post
-
The bus weighs 85 lbs. There just isn't enough room for a bigger reverse.
-
[/color] The MD4-E uses bus gears. The 2-D uses much larger gears than a bus.
Thanks for setting me straight. Mendi's Nomenclature system is a little lacking IMO. I can never keep their boxes straight without looking them up.
Also, I think we are scaring Icky to much here. The reverse works! Just don't abuse it.
The people who say "they can't use it" Have V-8's and 36" tires.
-
Engineer is right on the money!
-
I was getting scared. I was thinking i guess I'll turn it sideways and run a cvt with an rpm. But everything has It's own set of problems i guess
