Long time lurker, first time poster. My B18C(ITR) from HMO should be here in a few days(didn't want to do a build up at this time). Anyone encounter any install issues in a 99/00 SI? (Searched and nothing on EM1 swaps for this application) I believe I have to retain my rear mount from my original(B16A2) engine? I am planning on leaving my A/C installed. I have the OBD2.2-OBD2.1 Harness. I would like to use my ultra-light flywheel(7.5lbs) from my CF DF clutch(have one in now, and have new one in garage). DC SS 4-1 Header still should fit even though block is slightly taller? I am changing Water pump, Timing Belt and tensioner(I gather the USDM ones will have to work, JDM might not be available here in US, or are they one in the same?). Anything else recommended that I need to change? Thanks for any comments/opinions.
