Its cool your dads a fabricator, thats really gonna help you on the build. Make sure he teaches you a lot of shit while doing it.
These cars are a bitch, have fun learning.
I think Guy Smilie put it best:
...These things are very trying and wear down your soul. I have been daily driving my 2JZGTE cress for a few months now and have already had to have my engine back out 2 times for DUMB shit, and this morning on my way to work..... my transmission started to make bad noises. These things will kill your will to live.
But they do sound good.
Like mitch said, dont be a retard and you should do ok.
On a personal note. I know that road, I know where it leads, and I know what got you interested in the cress. Please dont burn that area more than it already is. I would like to return there someday and NOT get pulled over by rangers every 10 minutes for driving an import.
