is this for real..swapping out the turbo cams for the n/a cams in the first gen is an upgrade?....are we talking seat of the pants type extra power....or 1.5 hp on the dyno sorta power?...just asking as ive got cam shaft seals that will need replacing in the nearish future...if i gotta go that far i might aswell upgrade the cams if its not gonna cost me much to get em
