Looking at doing a b20b vtec swap, But not sure on the heads, and some of the other stuff. Ive been lookin around and from what I've seen there seems to be a lot of issues with valve clearance on some of the heads like the b16 I think it was? and on the gsr if you mill it to get a decent amount of compression? But does the b17 head yeild decent compression matted up aginst the b20 with good clearance? And all the other stuff that comes with it, like claying the motor and I doubt it wouldnt be a very bad idea to have the rotating assebely balanced...Would it be worth it just to do the full h22 swap? It would just be a daily driver n weekend racer... something to have fun in...not trying to spend over 4000 on it...
