So if there is one thing i learned while in process is... Take that final figure you have and tack another $1000 on it. I did the same thing you did, research, adding figures etc. Now that I'm 1/2 way done Im finding all this little nickel and dime shit that I didnt account for, and other parts I didnnt initally plan on buying... I.E new bearings, new steel braided lines, fancy lever's, billet shit so on and so forth. Granted I could probably get away without buying some of it, but if im this far in already why start half assing now.
Anyway good luck on your projecy when u start
