Even at $3300, compared to other kits out there like the FMAX, the IAP kit owns. I've already seen the log manifolds and cast manifolds, great for low boost power but eventually I wanted to build for high boost. The IAP manifold may not have a merge collector, but at that price it more than does it job for bang / buck considering what it is..... and if people can make 500RWHP on the cast manifolds than I imagine that this will only do a much better job.
IAP's newer manifolds have much better welds are are very think, mild steel, which is good. Since the think mild steel and the coating on the manifold does a good job of not cooking everything under your hood like stainless steel would if it weren't ceramic coated.
As for the Greddy Kit... Hmm let me see, the turbo uses an internal wastegate, external wastegate is just plain more flexible better and more expensive. The T3/T04E turbo is better matched for the KA and has proven to make big power, rather than "potential". The Greddy fuel solution rocks though... The Greddy kit is a great way to go if you want a low boost car and want to keep it there...... And just because the turbo will support up to 450HP doesn't mean everything else on the kit is great for that. At that power level consider an external wastegate solution and manifold for better boost control.
How ever you decide to go, full kit or piecing everything together is up to you. I saved myself the trouble of shopping and driving around for parts here and there and just bought the whole kit..... Pricey? Compared to other kits and what I was getting, no. You can always find a away to go cheaper, and cheaper, no matter how cheap you go someone will be even cheaper. I'm happy with what I got for what i paid.
