I wouldn't think that vortech would have info on whether or not it fits motor A in car B...
but you never know it's worth a shot...
I just searched h-t...
http://honda-tech.com/zerothread?id=276029
it's kinda confusing there's no real answer... the vortech will only fit on the a2 not the a1.. cuz of the powersteering pully type... but I believe they said you can swap that... also someone posted a pic of it done (I think the pic was no longer available) try to pm him and see if he can dig up the pic for you.
Just a side note just about everyone agreed you don't want a vortec... they're all saying jr or turbo (go turbo) and their arguement is pretty valid... the vortech doesn't spool up for a LONG time because it WAY oversized... so it has the draw-backs of BOTH turbo and sc... IE parasitic loss at idle and low rpms due to it being pully driven... AND lag... lots of it.
hope that was some help.
read that thread it'll get you going in the right direction.
