How hard could it be.....
 

I was just wondering how hard it would be to fit a new engine? Is it something that somebody with limited emgine knowledge could do with a Haynes manual and another set of hands or is it really something for the experienced mechanics?

Like if i was to switch my engine for the exact same with lower mileage? Or if i was to put a vtr engine with the same style of ecu in?

long as you got the tools the time second pair of hands and a manual can't see why you couldn't

You could do it yourself, but it would be better to get someone who knows what they are doing, but still do it yourself aswell to learn.
