by the way the other reason people do ls/vtec is u actually end up with more displacement than a b18c1, but im wondering if you could just put the crank and pistons from the ls motor into a b18c, would that achieve the same affect? an ls/vtec engine will net you 1834 cc's and a b18c1 comes with 1796 i believe.

and what makes lz/vtec more unreliable is the fact that it has a longer stroke... or so i've been told.. it's bottom end wasnt made to take the high revs required to achieve performance gains using VTEC... i'm kinda sick right now and not quite up to informing people... but i think i got that right
you'd be better off overboring the b18c1 to make up for the difference, and then adding higher comp pistons... you'd end up with somthing *prolly* more powerful than a c5... with a port job and larger injectors and fueling system in general that is (to increase airflow for the larger displacement as well as giving it enough fuel to feed)

you are correct about the longer stroke being the reliability problem, the other reliability problem is the fact that the bottom end is not built for vtec and doesnt have the necessary oil passageways, you need a new oil pump etc. to make this reliable

do they make stroker kits for the b18c1? because that would also have the same effect as trying to put in the crank etc. also i doubt the engine would be more powerful than a b18c5, as the c5 incorporates the b16a head (i dont remember which one at this point?) along with a few other differences, but with both the head and the boring you would def. have a more powerful motor

btw StreetRacingCRX, to answer your question, i would stay away from any frankenstein combo engines, and i would go with a b18c1 from the gsr, its not an INCREDIBLY expensive swap[i know its still a little pricey, look to pay at least 4000 if your doing all the work yourself], but is about hte best money to power ratio. The b18c5 is the quickest, but it is not difficult to build a b18c1 to get it to the same power

anyway, doesnt the c1 head have a higher compression than the c5 head? i think that with high comp pistons that the c1 head could make more power than the c5 head...
