Retep im in a simmilar situation to you.
I paid fuck all though.
I have a few runs and the enginebay is less than pleasing
My guy seems happy to redo it, but that will set me back a fuckload. I'm am just going put the motor in and get the innerwings redone etc.
Next time I am def going to give it a shot myself aye, atleast if I fuck up I only have myself to blame.
I'm happy enough for the time being though
