I am nearing completion of my B18B1/B17 LSVTEC. Its a stage 1 level engine built ground up. The head was decked .005 in and the block was decked but I don't know how much. I bought it that way. I will have about 10.8-11 compression using SRP pistons and have Skunk2 Stage 1 cams. I have the center line spec for the VTEC lobe on the cams but I don't have anything to lock the VTEC rocker to degree the VTEC lobes. I have the dial indicator etc. but thought maybe I could degree the primary lobe (if I had the spec).

Otherwise my options are:
Don't degree the cams or
Degree the VTEC lobes by disassembling the head, locking the #1 cylinder rockers, degree the cams, disassemble again and put everything back to normal.

I don't feel I want to risk not degreeing but the other option is a lot of work.
Any suggestions?

 

I'm not a tuner by anyway, but just a out of the box thinker..


why don't you just take the valve cover off and put like a plastic rod or something in where the spark plug goes and rotate the crank untill the plastic rod is at the very highest point then rotate your cams accordingly?


my .03 cents.

 

That is the concept but the devil is in the details. To rotate the cams accordingly you have to have the spec for the cam lobe, at what point in degrees of crank rotation after TDC or Before TDC does the cam reach its max opening position. I have that spec and a way to measure both the crank rotation and valve opening. The issue is that the spec is for the VTEC cam lobe which under non VTEC conditions is free wheeling. Its not opening anything. I have to find a way to "lock the VTEC lobe" so that it does operate the valves. There may be a special tool for that which is one of the suggestions I am hoping to receive or the other alternative is to strip apart the valve mechanism for #1 cylinder and mechanically slide the VTEC pistons into place by removing the springs. Thats the part that is a lot of work. The other possibility is to use a spec for the non vtec lobe. I don't have a spec for that. Thats the other thing I was hoping for in this post.

 

I have seen this device in many car mags when they assemble a block, that like has a clamp on one side then a micrometer on the other side that you can have riding on the top of a cam lobe and rotate it, basicly to index your own cams or find out at what point it reaches TDC or BDC couple this along with another one of the micrometers and you can read the TDC of the pistion also.

although I have never assembled a block before only helped with a big block in a hotrod.. honda's are much funner.
