Fiat 126 BIS - want to put bike engine in!
Discussion
Hiya,
I have just bought a Fiat 126 BIS (Have an old aircooled one too). I have had some bad luck with the engine and it basically needs a new one !
Whatever I do, I will have to do it myself because of the cost so I thought why not put a bike engine in. I do need to ask a few questions, I'm sorry if they are silly but I'm a bit new to this.
1) What engine ?
I need an engine that I can get relatively cheaply (say £175 max). The current engine is 2 cylinder, 700 cc, 24 bhp. I understand that most bike engines would be so much more powerful that this :-S
(btw, the car weights 640kg approx)
2) Gearbox
This may seem silly idea but could I not use the current gearbox, and have some sort of chain drive from the engine to the gearbox ? Using sprockets so that the ratio could be pretty much the same. The only problem I can see with this is that the gearbox may not be up to it. But if I didn't do this what would I do about the diff and reverse (and putting a reverse unit in is too expensive to consider, lol)
3) Mounting
I gather you can weld in some sort of frame to mount the engine ?
Thanks for reading !!!

Thanks very much for your reply !
I'll have to look in to adapting the gearbox. Another option is to just leave the fiat gear box in 4th permently and use the bike gearbox, although this is not very suitable!
What's it like driving a car without diff ? Will it turn properly ?
I will post more soon !

Hiya, just a little update!
I rebuilt the engine in my Fiat 126 BIS (the water cooled one), so that's all sorted now! But started some mad work on my Air cooled Fiat 126. So far I have cut the roof off, trimed it all down with angle grinder, cut all the dash back (off), ripped engine and gear box out. The current plan is to cut the rear corners off the car and fit the rear end of a motorbike.... exciting hey ?
Hoping to cut most of the rear body away and fabricate a new 'pointy' rear. I'm at the stage about wandering about which motorbike, and need to ask a few ppl. I think something around the 500cc / 40-60bhp would be amazing considering how light the car is. I think a watercooled engine might be a good idea (?), on the other hand, air ducts could be arranged to flow air over the engine.
I know strength of the body is going to be a issue...
Any ideas as to a motorbike that would be suitable ?
