What is your budget? feel free to PM if you dont want to say on here. just want to point out one of the cheapest conversions is to leave the engine in the front of the car and modify very little else apart from whats needed to get the engine in place. K series has been done alot so a lot of info is about, the micra one is quite new so not alot of info but the engines are reliable, or Vtec - lots of power and quite alot of mods required. 16v mini forum often have conversions for sale that people have built and got bored of.
Just as a pointer, ive added up the costs of my micra conversion - ive had alot of work done for me + most of the parts are custom + bought new..im currently at 3 grand and its always going up.
My budget is about 3 grand including car and engine. I just want to keep it as low as possible and my knowledge of engines and gearboxes etc is pretty limited. I'm very proficient in electronics but other than that not great. My dad used to do this kind of stuff when he was my age and he thinks this is going to be a huge task and I'll just end up with a pile of parts. Is the whole thing really that difficult?
