The SR20 you currently have fitted is the better option because you have a lot more cam selections... that is a roller-rocker Sr20 out of a p11
The car however, looks really really really good !!!
I'm planning on keeping the highport I've only bought this block to swap over timing chain cover upper and lower sumps as previous owner has cracked them causing to leak a bit oil .
And thanks should be finished by end april fingers crossed
