183.5 HPs only if it came straight from japan and only had 25,000km. If it had more, substantially less HPs. If you got one with an adjustable power band, you should be rockin' the high 190's of HPs if you play it right and only use JDM gaskets and JDM axles.
I have that exazckt same setup. It's so JDM it's off the chain y0.
Or maybe you'll figure out that you won't gain more than roughly 10hp with those mods. If you want to play, you gotta pay. Turbo or n/a build it or don't expect miracles; your choice.
