yup b20 fits just fine...it is a 2 litre DOHC non vtec motor. there are three versions I believe, the most desireable being the b20z because of its higher compression ratio. The b20 is best known for being the "torque monster" of the B series Honda line. These can be re-sleeved and boosted like a bitch, orrr recently there have been many NA builds on the b20 that have put down some very impressive numbers.
