I was about to do a ZC swap w/LSD tranny for my 1990 CRX Si due to it's ease and low cost. The guy that is going to do it says it would cost me $1700 installed, but he then told me about doing a B16 w/ an LS tranny with LSD and have everything done for $3K, but I don't know as much about the VTEC stuff, nor anything at all about the Acura tranny. I believe that he said there was a brand new Phantom Grip (?) LSD in the tranny he guaranteed was good and functional, but I don't know a thing about that. What I'm getting at is this: Should I go with the ZC or the B16 with almost double the cost for the performance increase? I'm looking for it to be a daily driver, no drag racing or track stuff, have it for snow/ice, inclement weather, etc., but have enough power to merge w/ traffic/keep from getting punked/run from the cops, etc... I've done enough research to know that having a ZC motor is a special thing, that comes with the need for 'special' parts and could be a real headache later down the road if I don't remember to specify them when replacing things, but I have no knowledge about VTEC and the B16. I need to have my decision by late tomorrow or early Tuesday so I don't lose out on the ZC availability if that's the decision made. Any and all suggestions or advice is welcome. Thanks in advance.
