Actually Mr. Jez is a cool dude in person. He actully swap my sr20de for my nx in no time like he claim maybe no more than 2 hrs. My motor was from soko too and Jez probable can tell you how shining it is. The block and head is superclean now i just need to adopt a Incon turbo to accomodate my 6puck and fidanza flywheel as my only mods. later, chee
