all of them (rs,ls ,GSR, TYPE-R )have the same block, the heads are different.
normally its an LS Bloc with a SiR head (or gsr head,or type-r) but Sir head is cheaper and have higher compression than GSR.
its called LS/Vtec and it give 190-200hp 140 pound/torque
and theres also a B20/vtec wich is CRV bloc(2 liter) and Sir head, THAT engine in a hatchback run low 14'* and 13 with slick. its 200+hp 160 pound/torque
but you can also supercharge a SiR engine (but you need lower compression) and it give 240hp (jackson racing supercharger) with a good setup. but its 5000 can$
but stock for stock, the Si civic is between the Teg GSR and the LS.
