i want to learn about crvtec but know almost nothing about it.. so i've decided to come to you guys. First off i've got a gsr so i already have vtec. Now i know on the crvtec it mostly consists of an Si head and the CRV block . But since i've got a gsr i wouldn't need the Si head, i'd just need the CRV block right???and even if i didn't need the Si head , would i just need the CRV block to do the conversion or is there more to it then that???How much would the block and any other parts that would be needed cost and could i get these parts at a junk yard?????... i've got a friend that can probably install it for me for a very good deal..so i don't think i'd have to worry about the installation...i really just wanna know everything about crvtec before i get serious with it....sorry for my ignorance...any help would be appreciated
