The GS-R is a B18C1 but in Japan it is known as a B18C SIR-G. The B16 is a rev happy engine that you can run the piss out of all day long but lacks the torque of a larger b-series so it's a perfect engine for the lightweight crx or EF hatch...not sure what your DA weighs. The DC2 (94+) was actually available with a B16 so it can't be too bad. If you can get a good deal on it then go for it...you can always sell the block down the road and use the head on a gs-r block and you practically have an ITR engine.
