if i wan buy h/i/e for my b16a2 or n e parts like v tech controler n **** it wud be the asme as b16 rite? are sir-1 n sir-2 parts compatible /same?

 

Yes they all are, now for a question about the B16A2 written in English:

My friend hydrolocked his 99 Civic Si (OBD-2), we need to get him another block, can we order a B16A1 and just put his head on it or do we need to actually order the OBD-2 version?

 

b16a1 = gay *** pistons and a different timing belt bracket/mount
