Naysayers - its a british trait. What they mean is they can't be bothered to put down the computer to do something useful themselves.
I'm in the process of changing a 1.8 k series in an mgzt for a T series, (mgzt forum) you would not believe how many peple have said it´s not going to work, not worth doing, there are better engines, it'll fail on emmissions, the list goes on! In the end I resorted to tell people to can it unless they had something helpful to say, or personal experience of such a swap....
All my life , if someone said to me " You cannot do that " or " That will not work " , then I ask " Why will it not work ? " .
If I do not get a reply , or just get waffle , I will try to do it .
If I fail then I will acknowledge that I could not do it but I will have the info as to why it did not work for me and will tell them why it did not work .
However , I will also acknowledge that , although I could not find a solution at that particular time I am not saying that it could not be done .
Other times I have apparently done the impossible
