for the ls/vtec, dont u just swap the heads or something like that? how much does that cost? having VTEC doesnt add any horsepower though so what is the point?..snoopy, i dont think im going to go with the B20...if i wanted 127 hp..i would just keep a SOHC...right? or is it just that the b20 has better chances for increased hp with the right mods?..ok..so the H22..is out of the picture right now..certainly does sound like it is going to be expensive...man..the b16a2 is 2800? thats kindof the one i want..but are all 99 civic si manual? cuz i have an automatic..which would pose a problem...ne one have any other engine purchasing links?..hmm...JLAUDIO has not responded?
