I agree with MatT3T4. With custom you can do little more then a kit can (SS manifold, choice of wastegate, ect..), but the out come is very much the same for a daily driver. It real comes down to downtime, MONEY, fabrication (who's going to doing it), and what the turbo setup is mainly for (trailer queen, or street racing).
I also disagree with the point that you "can do little more than a kit can."...
Not only do you choose manifold material, but size, shape, wastegate placement, flow characteristics, etc. You can choose from a zillion different companies that do ceramic/heat treatments. You can opt for larger/smaller diameter IC piping, intercooler size/shape/flow characteristics, gauges (EGT is much more accurate than a/f, but you don't see kit-makers including that, do you?!), an ENDLESS number of fuel management/delivery options (FPR's, standalone/piggyback ECU's, upgraded injector size/brand/type, in-tank/in-line fuel pumps, FMU's, MAP bypasses, etc, etc...), IC interconnect tube COLOR (for you show-ers out there), turbo A/R ratios/trim/exducer sizing/water-cooled, downpipe size/placement, air filter size/type, oil/water line type/size, plus a ton of other things I surely forgot.....
I tell you, I've learned so much, and I'm excited to see how my set-up compares to the pre-fabs on the market.
Hopefully this opens the eyes to some of you that are truly interested in knowing your project-to-be inside and out! Keep an eye on my posts for updates/info about my project.
