hmm i think the GSR weighs in at 2670 and the ITR at 2639. don't quote me on that, but the ITR isn't that much lighter, but uses heavier parts while maintaining the 26XX lb weight of a teg.

then again i'm not so sold on curb weight figures from the factory b/c people have weighed their 4th gens at 2750, their 5th gens at 2800, etc etc (with all different levels of fuel) so i don't know.

back to the discussion:

i think the H22 is a superior engine to the b18c1, b/c of output and torque. like they say, there's no replacement...
