Have you ever drove/rode in a h22 civic, it is really only good for a straight line... Also, without a LSD, an h22, with all of the extra torque, would simply melt the tires off the rims...
So unless you got a Lude or an Accord, I would have to say the ITR...
However, these are both rare and expensive, so choose wisely...
And despite what these guys say, the ITR motor is overhyped for a reason... It will run at 8000+ rpms all day long because it was designed for this operation - With low-friction coated pistons, and dual valve springs on the exhaust valves...
Yes, the ITR motor is way more efficient, but definitely not worth the extra cost.
With a good set of springs and shocks, an H22 Civic or Integra will perform well. The H22 is not much heavier than the ITR motor.
