thanks for all the advice/tips/links. i've been looking around for parts and not having too much luck to be honest. does anyone know any good sites/people to go to to find what we're looking for? (decided on a more off roading type thing, like this - http://www.youtube.com/watch?v ... TL&videos=DeT2opx3Lak)
also, does anyone know any good magazines (with classifieds) for this type of vehicle. i looked in smiths with no luck (although farm machinery enthusiasts were well catered for :irked
Make it simpler, stronger and less powerful (and therefore a LOT cheaper) and build two, so that you can race them against each other. 40hp is plenty (20hp would be enough). Make sure that the roll structure is strong enough.
Anything between 600 and 900cc made within a decade should be great. Preferable to be widely available and renowned for reliability so I presume any of the mainstream Japanese companies's bikes are good .
Actually, I think you might also want to look at snowmobiles. They are more or less equipped with the same engines that are on their motorcycle counterparts but the CVT transmission is a better base then tweaking with a motorbike chain transmission or an expensive sequential gearbox from Holinger or Quaife.
maybe not as high-performance, but in terms of length and size, yeah. car shocks aren't long enough and thus don't have enough travel... either pickup trucks, or those truck/van hybrids like the jimmy/blazer/bronco.
(i'm not sure if they made any of those over in the UK)
A pickup will definitely not have that kind of setup. Your best choice for something similar is either an off road shop or to try to find a professional off-roader at a junkyard and salvage its suspension.
While you're at the junkyard, you could also get the brakes from a Ford or a Vauxhall. Should be both cheap and sufficient for a build as light as yours.
ok. how much would you say is a reasonable amount to spend on an engine given our budget? (found a few possible engines online, and want to know if they're too pricey (or suspiciously cheap)
