Guys - the geek of an engineer that I am (really OCD like (h) ) - wants to know more! I haven't read up on turbos as I was planning s/c so the buzz words are above me & as to their purpose also! (I am questioning myself on fitment of s/c vs Turbo) So Once you are up and running and have some time to kill (snow on the ground - that kinda thing) could you help me out with the lingo, the Y's n what 4's Cheers and dont forget to keep the pictures coming kevhaywire. I watch with interest!
