Dunc, don't give up mate!
Sounds like you've hit the 'wall' like marathon runners do at the 15 mile mark. You feel like you've done so much, yet the end doesn't seem to be anywhere near in sight.
Plus you're at the stage where everything is stripped out, and you are looking at a bare shell and a huge pile of bits. It's at this point that you think 'how the f**k am I ever going to get this all back together again?' Perservere and you will.
It's also worth bearing in mind how much you've already got done in a short space of time. Some restorations/ projects take years to complete.
If it's any consolation, I bought a 1974 Ford Cortina way back in 1990 to restore/ modify. It took me three years to get the bodywork done/ resprayed, put in rebuilt suspension/ subframes, strip and rebuild a 2.8 litre V6 and do what seems like a million other jobs. Though I got it about 80% finished by late 1993, it's still sitting in a lock up waiting for the final injection of cash to get it on the road. Change of career plus working/ travelling abroad meant it had to be mothballed. I've only had it for 15 years...
Plus you'll find that the most satisfying point of a restoration is when you do start bolting bits back on to your restored shell. As long as you've labelled everything and made notes during disassembly it should all go back a breeze. It's the old adage about 'preparation is everything'. Do all the prep/ restoration work on the parts first before fitting up, and it will make it go back together much quicker.
As for the time and cost, both classic and custom car magazines used to say the same thing about doing a project like yours. Work out how much you think it will cost and also how long it will take to do. Then at least double those figures (more likely treble them) and you'll come closer to the real cost and time needed
And as Fro$ty said in an earlier thread, think of the satisfaction you'll get when you have a rust free Uno turbo and even better when you can blow the doors off some expensive modern car that costs ten times as much as your turbo.
Don't give up, we're all willing you on to finish this!
Keep us all updated please!
