Possible to build a 400whp sr that spools by 2000-3000rpm?

I know that with every motor your “Pondering” you plan to build it or w.e. But with any turbo motor u will need a custom computer. whether it be a safc, or a standalone. or an ecu done at jwt or w.e u will need something done to the ecu on fuel injected motors. You cant just up hp without changing injectors etc, and that means ur computer wont be putting out enough fuel and BOOM there goes ur motor. ka’t is a good choice for a little fun on a cheaper budget. Theres a few guys with only 2 grand into their ka and its turboed with a t25 run on a safc etc etc. Probably around as fast as an sr if not faster, but alot more torque.
