The hose is most definitely rubber. It's a preformed hose, so you need to be sure you buy a hose that has the 90° bend already formed into it. If you use straight hose and bend it, it'll kink up and restrict flow.
The engine was rated at 230ish peak horsepower (utilizing the turbo), so around town driving with your foot out of it will be producing much less than this. My former turbo supra was a little doggy when I first got it, properly setting the ignition timing helped TONS. Not saying that's what is going on with yours, but it's easy enough to check and adjust.
