Hey, i know everyone asks this, and i tried searching but came up with nothing that was applicable to my situation. Most ppl ask this question for their old crx's or HB's. I have a '97 Civic Dx. I've finally saved up the money to buy my motor. I've been told the B16Sir2 (obd2) would be a good buy. However, it must be impossible to find because i have yet to find one. So, my question is: Should i just buy a gsr motor instead? Btw, i am going with forced induction. Or should i just buy the b16a2 and miss out on the 10 hp and few lb's of tq and spend more? I had planned on using the gsr tranny anyways with my b16. Are GSR's good for boosting? If so, would a GSR be a reasonably easy swap? Thanks. P.S. If you have suggestions for other motors, please let me know.
