custom or premade turbo kit?

should i take the time and save some cash and custom fabricate a kit for my 00 f23? or should i just save the cash and go premade kits like f-max? im pretty confident i can go custom but the time involved of fabricating I/C piping and so on might be too much hassle than its worth. was thinking of buying manifold from turbo-performance.com used or reconditioned t3 or t3/t4. new intercooler etc. maybe be around $2000-2500 or go for fmax at 3000.
