The full race kit is fantastic
Although it is just the turbo and associated exhaust side plumbing.
Add injectors (400-600), fuel pump (80-100), standalone (1000-3000), bov (300-500), front mount (600-1200), intake (80-160), filter (20-100), tuning (500), oil lines, fittings, oil pan modification (100-200), downpipe (150-300) +++ misc fabrication bits, and you’re up another what, 3.5-6k?
The GReddy turbo kit is a bolt in affair, we have installed one and were impressed with almost every aspect of the kit. It is designed for someone that wants stock SR20 performance with KA reliability without the headaches that come from an SR swap (losing A/C most of the time, possibly ABS, putting an unknown engine in the car etc)
You can then expand the GReddy kit as your plans unfold, the turbo has more than enough flow to make it work, and the emanage is capable up to 300whp at least
Did you check out ETS’s kit? It comes with everything you need to go turbo but the injectors and ecu. Less money than the Greddy, substancially better turbo, manifold, down pipe, in addition to IC, IC pipping, turbo intake, fuel pump and it’s a direct bolt on. So no need to find your own custom IC pipping solution for a ka…which is a pain haha.
