300 whp you *could* still be very streetable, although half the time you'll be smoking your tires. Unlike FR BMW's, it's much tougher trying to make a FF car hook (not to mention a waste of money IMO).

Mid-sized turbo on a built engine running high boost.

If you want big power I would ditch the integra (again, front-wheel drive just isn't practical for hooking up all that power).

You would be much more satisfied with 220-270 whp in something like a civic hatch. It's still FF but it's easier to lose weight than to tame 300 whp of wheelhop and torque steer.
