I have a Y8 head, traded it for some work. I took it apart to make sure that everything was okay, and noticed that one of the rockers for the VTEC lobe was broke!!! I was wondering whether I can get just one rocker, or if I had to replace the entire assembly. Ive got all the other parts that I need to swap it onto my Y7 block, but I need the rocker arm assembly to work, or just have vtec on 3 cylinders.... haha.... just wondering what I need to do. If i need to replace the whole assembly, I will probably just put the Y8 intake manifold on the head and save for a b or k swap. If I DO end up doing the manifold swap, can I reuse all the parts off of the Y7 manifold? IACV and all that? Or will I need to use a 2 wire IACV, what about fuel? Will I need to get a fuel pressure regulator so that I dont burn too lean with all the extra air? Or will the ECU still give me the same ratio? ANY input would be appreciated

 

Should I just do the manifold swap? Im thinking that I have to replace the entire rocker arm assembly. Im not sure whether the IACV is compatible with the y8 manifold. Can anyone tell me that? I will just put a fuel pressure regulator on it to compensate for the added air, thats the only thing that I can figure

 

no, the only rockers that will have the be replaced is the set for that cylinder, and for that side, say you broke the intake primary rocker, 3rd cylinder, youd have to replace all three of them for that cylinder, thats it. if yoor putting a y8 manifold on a y7, use the y8 parts, the y7 tb wont work on the y8 manifold, it touches, and the fuel rail and regulator from the y8 should be used as well. use a 2 wire IACV setup, and cover the third wire if you have one.

 

i priced a rocker assembly for the intake side on the number 1 cylinder.... $135... i dunno if i want to put that into it or not, i have everything that i need for the manifold swap, so i may just do that. as far as the ecu goes, if i cover just the one wire, wont that trigger a code? should I just use the y8 ecu and have a code for vtec and the knock sensor? or will it not run right with that?
